The Secretary of State for Transport (Heidi Alexander)
With permission, Mr Speaker, I wish to make a statement regarding the power outage, caused by a substation fire, that impacted on Heathrow airport operations on Friday 21 March.
I begin by acknowledging the disruption to everyone affected by this incident. Many homes, schools and businesses temporarily lost power, some families have had to evacuate their homes, and many thousands have had their travel plans impacted. I thank the firefighters and emergency responders who worked in difficult conditions to put the fire out, as well as Heathrow, the National Grid and all the other public services involved for working so hard to get power back on and people back travelling again. This was an unprecedented event, and we must learn any and all lessons we can to ensure that it does not recur.
Let me begin by setting out what we currently know about the cause of the incident. A large fire broke out at North Hyde substation at 11.30 pm on Thursday 20 March, and was brought under control the following day. Due to the impacts, Heathrow airport announced at 4.30 am on Friday that it would close until midnight that day. Power was restored to domestic customers in a matter of hours, after the operator of the local distribution network, Scottish and Southern Electricity Networks, redistributed power through other parts of the network.
By comparison, Heathrow is one of the country’s biggest consumers of electricity and requires as much power as a small city. What we know is that there was an unprecedented outage, and that it was not the result of a single point of failure on the electricity transmission or distribution system. The feed from North Hyde substation is one of three supply points to Heathrow, and the fire caused exceptional damage that took the whole substation out of service. The other supply points continued supplying to Heathrow airport throughout the incident.
Heathrow’s view was that that supply was insufficient to ensure the safe and secure ongoing operation of all systems across the whole airport. It proceeded to reconfigure its internal electricity network to enable the resumption of full operations, utilising the other two external supply points. That required hundreds of systems to be safely powered down, and then safely powered up, with extensive testing. The airport has a range of back-up generators and uninterruptible power supplies, including diesel generators, to provide power to essential systems to enable them safely to land planes. Those back-up systems ensured that safety and security systems and protocols were maintained at all times, but they were never designed to support full operation of the whole airport.
By 2.30 on Friday afternoon, Heathrow began restarting systems to ensure that they were safely operating. By 4 pm, the airport was 100% confident that all systems were safely operating across the whole network, and announced that some flights would be able to restart that day. The first flights, from about 6 pm, were so-called positioning flights, which were to get aircraft and crew to the right places to resume normal operations the following day. That was followed by flights diverted to UK and non-UK airports, to allow passengers to be repatriated, and a small number of outbound long-haul flights. Since Saturday, Heathrow has been fully operational, with more than 250,000 passengers able to fly to and from the airport on Saturday. Due to knock-on impacts of the event, there continued to be some delays and cancellations over the weekend.
Overall, the impact of Heathrow’s closure led to over 1,300 flights and more than 200,000 passengers having their flights cancelled or diverted on Friday, and a further 110 cancelled on Saturday. The Government are acutely aware of the need to ensure that passengers are well looked after and their consumer rights protected. This is why UK law ensures that airlines must provide passengers with a refund within seven days, or passengers must be rerouted to their destination under the same conditions. We are closely monitoring to ensure that passengers are properly supported. To support the recovery, my Department temporarily lifted restrictions on overnight flights, to ease congestion. Heathrow and airlines also added extra capacity into the system to help affected passengers. We allowed rail tickets to be used flexibly to help passengers who were not able to use their original tickets.
Regarding the cause of the fire, the Metropolitan police confirmed that the fire is not believed to be suspicious. However, due to the location of the substation and the impact that this incident has had on critical national infrastructure, the Met’s counter terrorism command is leading our inquiries into this matter. This is due to the specialist resources and capabilities within that command, which can assist in progressing the investigation at pace to help minimise disruption and identify the cause. It would not be appropriate to comment further while these investigations continue, but we will of course update the House once it is appropriate to do so.
Although it is positive that electricity supplies were restored quickly, there will be learnings to ensure that we avoid such incidents reoccurring. That is why on Saturday, my right hon. Friend the Secretary of State for Energy Security and Net Zero, working with Ofgem, commissioned the independent National Energy System Operator to urgently investigate the incident. The review will also seek to understand any wider lessons to be learned for energy resilience for critical national infrastructure. NESO has been asked to report back to the Department for Energy Security and Net Zero with initial findings within six weeks.
In addition, Heathrow has asked Ruth Kelly, a former Secretary of State for Transport and an independent member of Heathrow’s board, to undertake a review of its internal resilience. The Kelly review will analyse the robustness and execution of Heathrow’s crisis management plans, the airport’s response, and how it recovered the operation.
Colleagues across the House will appreciate that we do not yet know everything there is to know about the incident, but I will try to answer questions from hon. Members in as much detail as possible based on the latest information I have at my disposal.
I commend the statement to the House.
Gareth Bacon (Orpington) (Con)
I thank the Secretary of State for her statement and for advance sight of it. I join her in extending my gratitude to the firefighters who responded so swiftly to the incident. I extend my sympathies to everybody affected by the disruption and place on record my thanks to all those at Heathrow who worked diligently to ensure that the airport came back on line over the weekend.
The loss of power in the Heathrow area caused significant disruption for thousands of travellers and countless businesses. Heathrow is one of the world’s busiest airports and Europe’s busiest air hub. It was scheduled to handle 1,351 flights, carrying up to 291,000 passengers on Friday. However, as we know, the fire at a nearby electrical substation forced planes to be diverted to other airports, with many long-haul flights returning to their points of departure. The financial cost of the shutdown to the airline industry is expected to total tens of millions of pounds, and there are significant question marks over the airport’s possible vulnerability to further disruption in the future.
Before we discuss the specifics of the incident, I ask the Secretary of State to confirm that she will remain engaged with Heathrow, the airlines and other key stakeholders throughout this period to minimise the impact on passengers and the economy.
I note that the Secretary of State for Energy Security and Net Zero, whom I am pleased to see in his place, has instructed NESO to investigate the incident urgently. It is crucial that NESO’s investigation delivers a clear and objective assessment of the incident’s circumstances and the UK’s broader energy resilience. I ask the Government to keep the House informed as that investigation develops.
I also note that the Secretary of State for Transport will closely monitor Heathrow’s internal investigation into the incident. She is right to do so. Although I trust that she will share any conclusions drawn from the report with the House, may I ask that she provides specific assurance today that she will indeed do so?
Let me focus on the details of the incident, which evidently raises significant concerns about the resilience of Heathrow airport and critical infrastructure in general. On Heathrow’s resilience, important questions arise about why the airport was dependent on a single electrical substation, which proved so vulnerable to such an incident. I understand from media reports and from the Secretary of State’s statement that although two additional substations are capable of powering the airport, doing so would require reconfiguring the power supply structure for all terminals. Does the Secretary of State believe that that set-up is appropriate for the country’s largest airport? Additionally, what assessment has she made of the power supply resilience of other major UK airports?
With regard to the resilience of our critical national infrastructure, the episode underlines the urgent need to ensure that our critical infrastructure is safeguarded against both accidental incidents and deliberate acts of sabotage by malign actors. Hon. Members will recall that when President Putin launched his illegal invasion of Ukraine, global energy markets faced immense disruption, which posed the most significant threat to European energy security since the 1970s. Despite that upheaval, Britain’s energy prices remained broadly stable, but only because the Government of the day took decisive action to protect businesses and households from price spikes as far as possible. That came at a significant financial cost.
The event at Heathrow reminds us that true energy security depends not only on price stability but on the physical safety of our energy infrastructure. Given the crucial role of airports in our economy, we must remain vigilant. In the light of that, what discussions has the Secretary of State had with the Secretary of State for Energy Security and Net Zero about ensuring that the energy supply to major airports remains secure? What is the timeline for the Kelly review, and will its findings be made publicly available? Will the Secretary of State engage with colleagues across Government Departments to assess and mitigate the risks posed by malicious actors who will undoubtedly have taken note of this weekend’s events? Finally, what specific steps will she take to strengthen the resilience of our critical national infrastructure?
Heidi Alexander
I am grateful to the hon. Gentleman for the tone of his comments. I assure him and other Members of this House that I will do everything I can to keep them updated, and I will continue the engagement I have had with Heathrow since the incident first became known to me. I spoke to the chief executive of Heathrow on Friday morning and again today. If my officials can do anything to assist those on the Opposition Front Bench in understanding this very serious issue, I am willing to facilitate any such meetings that the hon. Gentleman wishes to have.
On the internal investigation that the London Heathrow board has commissioned Ruth Kelly to do, as the hon. Gentleman knows, I have asked to see a copy of that report. Assuming that I have the permission of Heathrow to share it more broadly, I am happy to share its contents with him and the House. On his question about whether I am content with and confident about the set-up for airport power supplies, I am not going to become an armchair electrical engineer; I want to see the report that has been commissioned by the airport and the report that my right hon. Friend the Secretary of State for Energy has commissioned from NESO. We are also conducting a resilience review of critical national infrastructure via the Cabinet Office, and I assure the hon. Gentleman that we will look at any and all the issues that this incident raises in those reviews. I spoke with my right hon. Friend the Secretary of State for Energy on Friday evening, and I assure the hon. Gentleman that I will continue to engage across Government on any of the issues that this incident raises.
Ruth Cadbury (Brentford and Isleworth) (Lab)
I thank the Transport Secretary for her statement. I also thank the fire services and the airport and airline staff who did so much over the weekend to address and support the situation and ensure that it did not get any worse. We will have a Committee session next week with the chief exec of Heathrow airport and others. We also look forward to asking the Secretary of State more questions when she comes to us after the Easter recess, by which time I hope that she and I will be better genned up on electrical engineering.
There has been talk this weekend about the single point of failure. In this case, that is about not just a particular electricity substation but what happens when our busiest airport closes. All our airports—critical national infrastructure—have an impact when they are at risk. I am told that the next airports national policy statement, like the last one, will cover only Heathrow. Is it not time that we had a national airports strategy to include what happens when any one of our airports is taken out of action?
Heidi Alexander
I am grateful to my hon. Friend, the Chair of the Transport Committee, for her remarks. The airports national policy statement is a site-specific document, but I will reflect on her suggestion of a wider airports strategy; I am sure that we will discuss it further when I am in front of her Committee in a couple of weeks’ time.
Mr Paul Kohler (Wimbledon) (LD)
I thank the Secretary of State for advance sight of her statement. I echo her words and those of others in expressing my gratitude to the firefighters and other emergency workers who fought the fire and to the airport, airline and other staff for all their hard work in the face of this catastrophic systems failure.
What has happened is clearly a rare occurrence, but it raises a number of significant questions about the security and management of our critical national infrastructure. While I am pleased to hear that no foul play is currently suspected, the event has revealed vulnerabilities in our national security that may be exploited in future by terrorists and hostile state actors. It is consequently vital that lessons are learned to ensure that an incident like this does not happen again, and I welcome the announcement of a full investigation.
It is deeply concerning that the failure of a single piece of infrastructure has taken down the entire airport. Heathrow is connected to three substations, and while two were impacted, the third was running and had enough capacity—thought to be around 72 MW—to power the whole of Heathrow, which requires a little more than 40 MW. It is evident that Heathrow’s power set-up could not be swiftly reconfigured to allow the third substation to be used. We need to understand why that was, and whether it could be remedied in future. While Heathrow claims that it is normal for airports not to have sufficient back-up capacity to power all of their needs, other industries that require even more power than Heathrow—such as data centres—take more robust steps to ensure they have sufficient back-up systems to counter such failures. Should our key international transport hub not have the same safeguards?
We must also not forget those whose journeys were disrupted. It is estimated that over 200,000 passengers have been impacted by the event. However, under current regulations, most of those passengers will not be eligible for compensation. As such, I have three questions for the Secretary of State. First, what impact, if any, will this incident have on the Government’s plans for expansion at Heathrow? Can the national grid infrastructure cope with a third runway, or will the airport become more prone to failure? Secondly, does the Secretary of State believe that UK airports should be taking steps to increase their back-up capacity, in order to ensure that an incident like this does not happen again? Thirdly, does she believe that the current regulations around passenger compensation are sufficient?
Heidi Alexander
I am grateful to the hon. Gentleman for his questions. The question of Heathrow expansion and this very rare—unprecedented—event are two entirely separate issues. He will be aware that the Government have invited Heathrow to bring forward proposals for a third runway, and we will review the airports national policy statement after that.
With regard to back-up capacity at airports, I am told that the back-up power systems at Heathrow operated as they should have done during this incident—they did not fail. I do not want to come to knee-jerk conclusions as a result of this unprecedented incident, but we will be looking very closely at the two reviews I mentioned in my statement. I have also worked with the Civil Aviation Authority to ensure that passengers who have been affected by this disruption are aware of their rights.
John McDonnell (Hayes and Harlington) (Ind)
Heathrow is in my constituency, as is the substation that caught fire, so I join other Members in thanking the firefighters who worked so hard to get this incident under control so quickly and at some risk. I also thank the police and the council officers who helped to evacuate 150 of my constituents from their homes. I was there on the day and met some of the residents, and I will be writing to them all so that we can pick up lessons from what they experienced on that day and build those lessons in.
Now that this site has gained such a high profile, there are concerns about its security for the future. I would welcome some more detailed information coming out of the inquiry about how we will secure the site for the future, not just from accident but from potential attack.
Heidi Alexander
My right hon. Friend raises a fair point. I will ensure that we provide that information to him once we have reviewed the different reports that are going to be published over the next couple of months.
Mark Pritchard (The Wrekin) (Con)
The Secretary of State mentioned consumer rights. Not only were Heathrow customers delayed and disrupted, but they were ripped off, with huge hikes for alternative flights, car hire and hotels. Is it not time that the Government brought forward robust anti-price-gouging legislation? In fairness to the Secretary of State and Labour Front Benchers, I also asked the previous Government, who did absolutely zero on this issue as well. [Laughter.] It is true, and I think we saw the result of that in many other ways. On behalf of the British consumer and international consumers, many of whom have been ripped off through no fault of their own as a result of this incident, is it not time that for new legislation? Should we not also carry out a wider review of the monopoly held by the operators of hotels at Heathrow and the lack of competition among airlines coming into Heathrow?
Heidi Alexander
I can categorically say that it would not be right for anyone or any business to capitalise on this disruption. Whether airlines or hotels, I would expect organisations to be doing everything they can to support travellers who have been disrupted by this incident.
Laurence Turner (Birmingham Northfield) (Lab)
The Secretary of State’s statement underlines why it is important to avoid speculation in the immediate aftermath of a critical incident such as this. Can she reassure the House that if any systematic risks are identified that potentially affect other major airports, there will be a co-ordinated response? If any such issues are identified at regional and local airports, will Members of this House in proximity to those airports be kept informed?
Heidi Alexander
I am happy to give my hon. Friend that assurance.
Jim Shannon (Strangford) (DUP)
I thank the Secretary of State for her answers. Of course, this is not the first time there has been a problem with Heathrow. Back in August 2023, UK air traffic control problems caused chaos. In July ’24, faulty software caused chaos again. We are always hoping that Heathrow is getting better. After the incident in the early hours of last Friday morning, 290,000 passengers—I was one of them, by the way—found themselves stuck somewhere in a queue. That includes many of my constituents, and they had trouble getting home, too. They have been contacting me over the weekend to tell me their stories.
The incident poses questions about whether the current operators are capable of running a third runway, if this fire caused a complete shutdown. Reports indicate that complete closure was not required. Confidence in travelling and in Heathrow are at an all-time low among my constituents and others. Has the Secretary of State made Heathrow officials aware of the need to ensure that contingency plans are not simply notes on paper, but actions to take during a crisis? What has been their response to allay fears caused by the turmoil of last weekend?
Heidi Alexander
I do not think anyone underestimates the distress and disruption that this incident caused. Having spoken directly with Heathrow’s chief executive on a number of occasions, I know that he is fully aware of that. This is an unprecedented event of significant magnitude. Day in, day out, Heathrow successfully provides services to hundreds of thousands of passengers and businesses. While it is right that we do everything we can to interrogate the causes of this incident and learn any lessons, I believe that Heathrow airport can continue to be a trusted partner for Government in the longer term.
Bill Esterson (Sefton Central) (Lab)
The power outage, which had such a significant effect on Heathrow and its immediate surroundings, has raised real concerns about resilience and back-up in our energy system for major infrastructure projects and sites. The Government have plans for a significant expansion of our clean energy electricity networks, so can the Secretary of State say to what extent the Government will build into their clean power plans the greater resilience and back-up that this worrying example at Heathrow has emphasised are so badly needed?
Heidi Alexander
I can confidently say that as we transition to clean power, resilience will remain key in the delivery of our power network. I do not think that anything changes as a result of our determination to move to clean power, but I am happy to continue discussions with colleagues in the Department for Energy Security and Net Zero to make sure that that is the case.
Sir Edward Leigh (Gainsborough) (Con)
Following that last question, can the Secretary of State give us an absolute assurance that nothing in our drive towards green energy and net zero will ever affect the sustainability and safety of our vital transport systems?
Heidi Alexander
I can give the right hon. Gentleman that assurance. I am aware that some other Members of this House—not present in the Chamber today—were busy peddling some myths on Friday morning about this issue. It is clear to me that Heathrow’s back-up power supplies consist of both diesel and electricity generators. No matter what some other Members might be saying, those systems did work. I can give the right hon. Gentleman the assurance that he seeks.
Clive Efford (Eltham and Chislehurst) (Lab)
Fires at electricity substations are not unheard of, and it seems that there may have been a considerable lack of preparedness at Heathrow. When the Secretary of State receives her reviews, will she look into what preparedness there was, and what scenarios those at Heathrow had envisaged for dealing with possible outages of this kind and getting their operations up and running again as quickly as possible?
Heidi Alexander
I think that the Kelly review will be looking at that. My hon. Friend makes a fair point about preparedness as well as resilience, which I will be discussing with those at Heathrow in the future.
Luke Taylor (Sutton and Cheam) (LD)
The level of disruption caused by the fire and the subsequent closure of Heathrow airport have highlighted the importance of reliable aviation connectivity to our daily lives, as well as the fragility of much of our UK infrastructure. The National Infrastructure Commission published reports in 2020, 2023 and 2024 calling for the Government to implement standards and frameworks for resilience in key sectors such as telecoms, water, transport and energy. Does the Secretary of State agree that this incident shows how important such standards would be, and will those in the appropriate Department pick up the reports which, I am sure, found their way on to their desks over the weekend and start to implement their recommendations?
Heidi Alexander
I think they are already doing that, because the review of resilience that was announced by the Chancellor of the Duchy of Lancaster last July is looking at the subject in the context of our critical national infrastructure.
Andy Slaughter (Hammersmith and Chiswick) (Lab)
I rarely disagree with my right hon. Friend, but I am not sure that this major incident can be entirely divorced from Heathrow’s plans for a third runway. It is precisely because it is up against densely populated communities that the effects were so devastating, with tens of thousands of people losing power, hundreds being evacuated, and part of the M4 being closed. Will my right hon. Friend assure me that as part of any consideration of a 50% expansion of Heathrow—which would presumably make problems such as this 50% worse—she will at least look into the risks, and the resilience, that would be consequences of such an expansion?
Heidi Alexander
I doubt that it necessarily follows that an expanded Heathrow that accommodated twice as many flights as it does currently would make an incident such as the one that we saw on Friday any more likely. This was an unprecedented fire of a significant scale. However, I can assure my hon. Friend that before making any decisions about the expansion of Heathrow, we will ensure that any proposals that may be forthcoming comply with all our legislative requirements.
Alberto Costa (South Leicestershire) (Con)
The Secretary of State mentioned that many families were evacuated from their properties. Safety is clearly of paramount importance, but only a few days ago NatPower UK informed me that it wanted to build an enormous electrical substation in my constituency. Once NESO has reported on this matter, will the Secretary of State please help to organise a meeting with the relevant Energy Minister so that we can discuss its findings and link them with any proposal for a new substation in my constituency?
Heidi Alexander
The relevant Energy Minister—my hon. Friend the Member for Rutherglen (Michael Shanks), who is sitting next to me—was nodding, which suggests to me that he would be happy to have such a meeting.
Matt Rodda (Reading Central) (Lab)
I thank the Secretary of State for her statement, and for the way in which she has approached this very serious issue. Heathrow is clearly a vital piece of national infrastructure; it is also central to the economy of west London and the Thames valley, and plays an important part in the attraction of inward investment to our region. As the Secretary of State works with the authors of the two reviews, will she also liaise with the local business community and local authorities in the Thames valley and ensure that they are kept fully abreast of the work that is carried out in the reviews?
Heidi Alexander
My hon. Friend has made a fair point, and I am happy to give him that undertaking.
Munira Wilson (Twickenham) (LD)
I again urge the Secretary of State not to divorce the question of expansion from what has happened here. Surely what this incident, crippling Europe’s busiest airport, shows us is that we need a better Heathrow, not a bigger Heathrow. We need to focus on the infrastructure in and around Heathrow, to improve resilience, security and the passenger experience. While a third runway may not increase the likelihood of such an incident, the impact of such an incident will be all the greater if she continues to put all our aviation eggs in one basket.
Heidi Alexander
Let me assure the hon. Lady that I am not putting all the country’s aviation eggs in one basket. At the moment we do not have proposals before us for a third runway at Heathrow. We will look at those proposals carefully when they are submitted and ensure that any decisions about either the airports national policy statement or any subsequent development consent order are taken in line with our environmental obligations on things such as carbon, air pollution and noise. Consideration of the resilience of the infrastructure will be part of that.
Mr Tanmanjeet Singh Dhesi (Slough) (Lab)
A “national embarrassment”, a “laughing stock globally”, “shocking”; with memes doing the rounds, those are just some of the words that could be used to describe this weekend’s events at Heathrow. While right hon. Members on our Defence Committee and the Joint Committee on the National Security Strategy were busy discussing hybrid and cyber-threats from our adversaries, our nation’s biggest port was taken down by a single substation fire. Does my right hon. Friend the Transport Secretary agree that, while my Slough constituents and people across the country are not bothered with the blame game that is now under way, this event should be a wake-up call regarding the resilience of our national infrastructure, and there should be no repeat?
Heidi Alexander
This was an unprecedented event and Heathrow stood up its resilience plans swiftly. Within 18 hours of the fire starting, planes were once again landing at the airport. For an airport the size of Heathrow, that is no mean feat. It is right both that an internal review of the airport crisis management and resilience plans takes place, and that the Government have commissioned the review that will be conducted by NESO.
Graham Leadbitter (Moray West, Nairn and Strathspey) (SNP)
The Secretary of State has indicated that she spoke to the chief executive of Heathrow on Friday and again this morning. I would like to think that, with an incident of this scale, there were ministerial contacts throughout the weekend, possibly on a more than daily basis, given the impact it had on so many people. Will she commit to urgently reviewing the DFT’s response to this major incident, in addition to Heathrow’s? She will also be aware that airports the length and breadth of the UK are vital transport hubs and linked to critical infrastructure, such as Aberdeen airport and, in my constituency, Inverness airport, with dozens of helicopter flights servicing offshore oil and gas and renewables infrastructure; and airports are also home to air ambulances, police helicopters and coastguard services. Will she therefore commit also to reviewing the level of operational resilience in those and other locations that host services critical to people’s wellbeing and to energy security and national security?
Heidi Alexander
I can assure the hon. Gentleman that, in addition to the conversations I had with the chief executive of Heathrow, I was updated throughout the weekend by my officials on what was happening at the airport. I am happy to write to him about the wider point he raises.
James Asser (West Ham and Beckton) (Lab)
As the Secretary of State is aware, my constituency contains London City airport, which sits closely alongside residential and business buildings, so safety is something we are very alive to. It is also an area of massive regeneration, so we are also alive to power pressure, and that part of her statement will be interesting for my constituents. Can she assure us not only that the review and the lessons learned will be shared, but that we will look at how they can be adapted, so that other airports can adjust and carry out future-proofing for their resilience, and so that we are not just learning lessons after the event?
Heidi Alexander
I am very happy to give my hon. Friend that commitment.
Dr Andrew Murrison (South West Wiltshire) (Con)
Does the Secretary of State agree that what happened on Thursday and Friday is a complete national embarrassment and should never have happened? Will she do an assessment of our remaining airports to ensure not only that they also have multiple supply points for electricity, but that they do not rely on the illusion, as plainly happened at Heathrow, that those multiple supply points made it completely reliable as a hub airport? That appears at first glance to have been the case for Heathrow, and it is not adequate.
Heidi Alexander
Perhaps the right hon. Member was not listening when I responded to questions from this side of the Chamber. There were multiple power supply points to the airport, but Heathrow took the decision that it needed to reconfigure the supply in the airport, as terminals 2 and 4 were very badly affected. It decided to put the safety and security of the travelling public first. It powered down all those systems and then powered them up again. I was not in the room when those decisions were taken. Heathrow is a private company, and it took decisions about what it thought was best for the travelling public. I, as Transport Secretary, am not going to second-guess those, but I will ensure that we do very thorough reviews. I will interrogate those reviews very carefully and ensure that any lessons we need to learn are acted upon.
Emma Foody (Cramlington and Killingworth) (Lab/Co-op)
I thank the Secretary of State for updating the House. As well as being one of the busiest airports in the world in its own right, Heathrow is also a crucial hub, meaning that connector airports, such as Newcastle International and others, are really impacted by any issues at Heathrow. Can she please assure me not only that a proper investigation is taking place, but that we will learn the lessons and ensure that there are no more such issues, and will she keep the House updated in the meantime?
Heidi Alexander
I recognise that Heathrow provides really important connectivity for our regional airports, and therefore for my hon. Friend’s constituents. I can assure her that I will keep the House updated, once both the internal review commissioned by Heathrow comes back and the report by NESO has been published.
David Mundell (Dumfriesshire, Clydesdale and Tweeddale) (Con)
Obviously, this event was on a catastrophic scale, but there is regular disruption at Heathrow. One of the consequences of that is the wholesale cancellation of flights between Heathrow and Scotland, which I have raised previously in this Chamber. When Ruth Kelly does her report on Heathrow’s resilience, will she look at its wider resilience and its ability to cope with weather-related or other technical issues, so that they do not lead to the wholesale cancellation of flights between Scotland and London?
Heidi Alexander
I am not writing the terms of reference for the Kelly review, because it has been commissioned by Heathrow airport itself, and I hesitate to stand at the Dispatch Box and try to amend the terms of a private company’s review. The aviation Minister, my hon. Friend the Member for Wythenshawe and Sale East (Mike Kane), tells me that the right hon. Gentleman has written to him about this issue, and he is due to come back to him on it. The matter is also being considered by the aviation futures forum.
Chris Vince (Harlow) (Lab/Co-op)
I thank the Secretary of State for her statement, and I add to the comments made by other Members by thanking those who dealt with this terrible incident at the time. It obviously had a huge impact on passengers, including residents in Harlow looking to get to the US. What reassurance can she give passengers that this was due to an unprecedented power outage? Does this add to the case for other airports such as Stansted, which employs some of my constituents, having greater resilience, greater capacity and, potentially, even transatlantic flights?
Heidi Alexander
My hon. Friend is tempting me to make a whole series of interesting comments about Stansted. I can assure him that when we get the reviews back, we will look at their implications for other airports, including Stansted, which provides employment for a number of his constituents.
Mr Joshua Reynolds (Maidenhead) (LD)
The fire and Heathrow closure will have impacted not only on travellers and on goods and services, but on the employees and contractors who work at Heathrow. Could the Secretary of State reassure me and those workers that she will urge all employers at Heathrow to ensure that staff who were due to work but were unable to do so, through no fault of their own, will be paid for that day?
Heidi Alexander
I am grateful for that question. I must admit that it is not a subject I have, to date, discussed with the chief executive of Heathrow, but I am happy to follow it up for the hon. Gentleman and come back to him.
Rachel Taylor (North Warwickshire and Bedworth) (Lab)
I thank the Secretary of State for all her hard work on this matter over the weekend. Can she reassure my constituents that our energy resilience remains high, and that the holidays they have saved long and hard for will not be disrupted by similar incidents at regional airports up and down the country? Will she also look into the particular impact that such outages have on disabled passengers?
Heidi Alexander
I will look at the specific issue my hon. Friend raises about disabled passengers, but I would like to reassure her and her constituents that I am confident that our airports and critical national infrastructure are resilient. I recognise that significant disruption was caused on this occasion. The NESO review will tell us if there are any other actions we need to take, but I am confident about our current arrangements.
Harriet Cross (Gordon and Buchan) (Con)
It is, first, really important to emphasise that energy infrastructure is generally safe. However, the example on Friday indicated that things can go wrong. What is the Secretary of State, alongside her Government colleagues, doing to address over-industrialisation in certain areas? In Kintore and Leylodge in my constituency, we have a 275 kV substation next to a 400 kV substation, with a 3 GW hydrogen plant and nine battery storage sites in the planning. Together, there is a huge risk, if we consider that a fire was able to start on Friday.

All these risks are considered in the round, but if the hon. Lady wants to write to an appropriate Minister in another Department and copy me in, I would be happy to follow up on those discussions.

Following the incident at Heathrow, will the Secretary of State commit to investing in regional airports, such as Blackpool airport, to diversify our air travel options and support local economies such as mine in Blackpool South, and therefore reduce our reliance on major hubs?
Heidi Alexander
Mr Speaker, I am really very sorry, but I did not quite catch the question. If my hon. Friend would like to write to me, I will ensure I come back to him.
Sir Jeremy Wright (Kenilworth and Southam) (Con)
The Secretary of State has, perfectly fairly, said that some of the specific learning about the incident will have to wait until we know more, but she also said that she has been told that, as a matter of design, the back-up power arrangements for Heathrow were not intended to cover all airport operations until, as we know, a significant reconfiguration took place over a matter of hours. Will she assure that she can and will begin the work of considering whether that is the right position, not just for Heathrow but for other airports? I make no predetermination on her behalf on whether it is or is not, but she can surely do that now without waiting for the specifics of this incident all to be clear.
Heidi Alexander
Heathrow, as a private company, is responsible for developing its own resilience plans. This is an issue that will be considered properly by the Kelly review, but the right hon. and learned Gentleman is right: I have been told that the back-up power systems were not designed to provide power for the entire airport. When I discussed the matter with the chief executive of Heathrow on Friday, he told me that is quite typical for an airport the size of Heathrow, but I am sure it is an issue the Kelly review will be looking at.
Lillian Jones (Kilmarnock and Loudoun) (Lab)
I thank the Secretary of State for her statement and associate myself with the comments of gratitude towards the firefighters and airport staff who responded to the incident. Will my right hon. Friend confirm that passengers have sufficient rights to receive support and compensation when these kinds of external events disrupt their plans?
Heidi Alexander
Airlines are responsible for providing passengers with a refund within seven days, or to be re-routed to their destination under the same conditions, with required suitable accommodation and food. That is the airlines’ responsibility. We have advertised the rights of passengers via the Civil Aviation Authority in recent days to ensure that people are aware. Those are the provisions that exist within our law to compensate people who have been affected by this type of disruption.
Bradley Thomas (Bromsgrove) (Con)
In any modern economy, it is clear that the resilience of critical national infrastructure faces many risks and threats, and that resilience goes hand in hand with our national security. Does the Secretary of State agree that the incident and other risks we face demonstrate that the role of the Prime Minister’s national security adviser should be bolstered to more prominently cover national security and critical infrastructure resilience?
Heidi Alexander
I assure the hon. Gentleman that the Government will do everything in their power to learn the lessons from this incident and ensure that our critical national infrastructure is protected and resilient as we move forward.
Robin Swann (South Antrim) (UUP)
The Secretary of State said in her statement that the review by the National Energy System Operator will seek to learn wider lessons for energy resilience and critical national infrastructure. Will that review include the infrastructure in Northern Ireland, specifically Belfast international airport in my constituency and Belfast City airport?
Heidi Alexander
My understanding is that the grid is separate in Northern Ireland. I will take away the hon. Gentleman’s question and consider with colleagues the appropriate geographical scope of the NESO review. The terms of reference have not yet been finalised, so I will come back to him on that.
