Disruption at Heathrow

Lindsay Hoyle Excerpts

Monday 24th March 2025 Commons Chamber

[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.

[Mr Speaker]

I call the Chair of the Transport Committee.

[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 Speaker]

I call the Liberal Democrat spokesperson.

[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?

[Mr Speaker]

I call the Father of the House.

[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?

[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?

[Mr Speaker]

A tenuous link.

[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.
