ECO4 and Insulation Schemes

Wednesday 29th January 2025 Lords Chamber

Statement

The following Statement was made in the House of Commons on Thursday 23 January.

“With permission, Madam Deputy Speaker, I would like to make a Statement about energy company obligation 4 and the Great British Insulation Scheme. The Government have identified an emerging issue of poor-quality solid wall insulation installed under those two inherited schemes.

Energy company obligation 4 began in April 2022, and the Great British Insulation Scheme began in May 2023. Around 65,000 households have had solid wall insulation installed under the schemes. In October 2024, TrustMark, the independent body that oversees tradespeople working in homes, did routine audits and found significant examples of solid wall insulation under those schemes that did not meet the requisite standard.

At that point, TrustMark began suspending a number of the installers responsible. After officials in our department were made aware of the issues, they asked TrustMark to conduct a much fuller audit, which concluded in mid-December. Officials informed Ministers at the start of December about the situation, and told them that early findings suggested that there were widespread cases of poor-quality installations that did not meet the required standard. Since that point, we have consulted the certification bodies responsible for overseeing the work, and the building safety regulator, to understand the true scale and nature of the emerging problem.

It became clear to me that there is a serious systemic issue around ECO4 and GBIS solid wall insulation. It ranges from minor problems, such as missing or incomplete paperwork, to major problems, such as exposed insulation or poor ventilation, which, if not fixed, could lead to damp and mould. As more poor-quality work has come to light, a total of 39 businesses have been suspended from installing new solid wall insulation in people’s homes. I can inform the House that suspended installers will not be able to deliver new solid wall insulation under any government schemes until they have fulfilled their obligations to put any issues right.

Additional on-site audits are being conducted as I speak, so that we can get a full picture of the scale of the problem and identify affected households. The auditing work continues at pace, and we have put in place a comprehensive plan for immediate repair and remediation where needed. Let me be absolutely clear about this: installers must fund any repair work themselves and carry it out as soon as possible. Consumers should not be asked to pay a penny towards the cost of getting the problems fixed.

We have instructed Ofgem, the energy regulator, to oversee that work. Ofgem will work with TrustMark and certification bodies to ensure that it is delivered at speed. Non-compliant work found through the audits is already being fixed. In the very small number of cases in which TrustMark audits found health and safety concerns, including wires not being fitted properly, the problems are being fixed urgently, with the expectation that they should be resolved within 24 hours.

Critically, I reassure the House that additional monitoring and checks are being put in place to ensure that future solid wall insulation is done to the requisite standard. It is also important to say that, based on what we know so far, we believe that the issues we have discovered are specific to solid wall insulation installed under ECO4 and GBIS. Stronger systems of checks and balances are in place for other schemes that involve local authorities and social housing providers, so we do not expect to see the same scale of problem there. However, the Government are reviewing the quality of solid wall insulation under other schemes. I will update the House on the results of that work as soon as they are available. We will continue to require the urgent remediation of any issues found across all government energy-efficiency schemes.

I know that this will be concerning news for families who have had solid wall insulation fitted through those schemes. Getting this sorted for those customers is our No. 1 priority. Since I was informed of the problems, I have worked with Ofgem to develop a full plan for assessing all affected properties and getting any problems fixed. Let me set out what our plans mean for those families. Ofgem will now oversee quality checks on all solid wall insulation installed under either scheme, to identify households that might be affected. That will begin with every measure being examined over the coming weeks by qualified professionals, and that will include looking at photographic evidence. If a quality check raises issues, the certification body that oversees the installer, or TrustMark, will arrange an inspection of the property and the problem will be fixed as soon as possible. Installers will be required to provide evidence to TrustMark that issues have been properly fixed. Let me reiterate our assurance that where solid wall insulation under the schemes has not been done right, consumers should not have to pay a penny to fix that.

We are clear that the responsibility for finding and fixing any problems lies with those who carried out the work. Consumers do not need to take any action now. However, given the inevitable concern among those who have had those measures installed, all households with solid wall insulation fitted under the schemes will be sent a letter from Ofgem in the next three weeks. It will set out the steps that we are taking, and how households can proactively raise concerns. We are also setting up a GOV.UK advice page specifically for those affected.

The Government are moving fast to protect households, but I must be honest with the House: these issues are the result of years of failure in a system that must be reformed. Home upgrades are, we believe, one of the best tools to get bills down for good and deliver warm homes. That is why our warm homes plan will cut bills for millions of households by upgrading their homes, including with solar panels, batteries, heat pumps and energy-efficiency measures such as double glazing and loft insulation. However, the Government have inherited a fragmented and confusing system of protections for people who want to insulate their homes—too many organisations with different roles and responsibilities, not enough clarity for consumers about who to turn to if things go wrong, and problems that should have been picked up earlier being missed. The system is in dire need of reform.

Installers are responsible for poor-quality installations, but they have been allowed to operate in a failed system that has left some households exposed to bad practices. The system can no longer command confidence, which is why we are committed to overhauling it, and to driving up quality and protecting consumers through the warm homes plan. We will look at the entire landscape —from how installers work in people’s homes and are certified and monitored, to where home owners turn for rapid action and enforcement if things go wrong—and we will ensure that there is more of a guiding mind overseeing upgrades across the system.

The steps I have set out demonstrate that the Government will do whatever it takes to protect consumers. We will regularly report back to the House about the steps being taken. We have set up a process through which colleagues from across the House can raise concerns about their constituents. Above all, we are determined to ensure that families are never let down in this way again. We will put in place a robust system of compliance, audit and regulation, so that consumers have the confidence to take up the offer of upgrading their homes. We will do what is necessary to ensure that families can have warmer homes and lower bills. I commend this Statement to the House”.

[Baroness Bloomfield of Hinton Waldrist (Con)]

My Lords, the energy company obligation scheme and the Great British Insultation Scheme were established to improve the energy efficiency of homes—one of the best ways to cut consumer energy bills and keep people warm. This is particularly true for those experiencing fuel challenges. We took significant steps to improve the energy performance rating of homes. By the time we left office, 70% of social housing had an energy performance rating of A to C, up from 24% in 2010. In fact, almost half of the measures installed under the GBIS have been to low-income households.

The installation of solid wall insulation makes up a small proportion of the work undertaken by the ECO schemes and the Great British Insulation Scheme. It is worrying, however, that we have seen examples of substandard solid wall insulation under the schemes as identified by TrustMark.

It is with that in mind that we welcome and support the action announced by the Government last week, in which Ofgem will oversee the repairs and remediation. We are also grateful to hear of a review into the quality of solid wall insulation in other schemes and that additional on-site audits will be conducted to inform future action. It goes without saying that installers should fund the necessary repair work to remedy impacted households, which may experience issues with damp and mould.

However, we look to the Minister to provide clarity. Will the Government publish a full list of the 39 companies suspended from the scheme for carrying out poor-quality work? Can the Minister explain how the suspended companies will be required to remedy their work, and how will the Government ensure that the remedied work meets the necessary standards? Finally, will the Minister clarify exactly what action will be taken to ensure that every household which had solid wall insulation implemented under the schemes is thoroughly and properly informed and provided with the necessary information to rectify the work?

I am sure that all noble Lords in your Lordships’ House can all agree that households should have warm homes that are both cheap and efficient to run.

[Lord Teverson (LD)]

My Lords, I gather from looking at the press release more than the original Statement that 65,000 applications will be checked through Ofgem procedures. Today I met someone who is affected by this, and I want to emphasise just the worry that the 65,000 or whatever will have over the future of their houses, their saleability, their onward renting or the damages to landlords. This is a real concern.

How many of the 39 companies that the noble Baroness, Lady Bloomfield, mentioned, were part of the TrustMark scheme? That scheme, which I believe all those contractors should have been a part of, is described as “Government Endorsed Quality”. What really worries me regarding future schemes—I know there is a big ambition on the part of this Government to carry on retrofitting—is that there will be a loss of confidence.

The one question I would really like an answer from the Minister on is about what I think is wishful thinking: namely, the Government’s view that all these issues will be replaced or rectified by the original installers. I do not wish to accuse the department of being naive, but let us be clear: the majority building business model is that when you get into trouble, you go into liquidation. I and, I think, other people really want to understand who will then bear the cost of those rectifications where that happens, as I suspect it will quite regularly.

[The Minister of State, Department for Energy Security and Net Zero (Lord Hunt of Kings Heath) (Lab)]

My Lords, I am grateful to the noble Baroness and the noble Lord. The noble Baroness has taken time out from Nuclear Week, which we have both been spending a very enjoyable three days on. She is absolutely right to stress the importance of the scheme. Clearly, there is consensus across the House on dealing with this big problem, as both the noble Lord and the noble Baroness suggested.

I make it clear that we have the evidence of an audit of about 1,100 of those 65,000, and there will now be a massive piece of work to follow up with further audits, which will be overseen by Ofgem. Some of those will be desk based and others will be in-person site visits. There will be a proportionality test to decide how the audits will be undertaken.

The sampling that has been done was geared towards the installers that were thought to be most risky, but the fact is that a significant proportion of that sample showed that there were major issues, which is why we needed to take swift action to conduct further checks and initiate a further programme of remediation. We think it is 38 installers, not 39—a correction has been made by TrustMark. To answer the noble Lord, of course they were all under the auspices of TrustMark, and we are working very hard through certification bodies and TrustMark to require them to remediate the work.

As the noble Lord pointed out, it is a requirement for those schemes to be registered with TrustMark. In the case of those already audited, this is happening. I believe most installers want to do the right thing and do a good job. My understanding is that where issues are being flagged, they are repairing the work, but clearly we are having mechanisms put in place to make sure that the installers deliver on their obligations, and the guarantee system we have acts as a backstop. Clearly, the current system is not working. There is a combination of TrustMark, the companies involved, the certification process and the UK accreditation system—there are a lot of bodies involved and there is not sufficient co-ordination or tight oversight of this. We need to focus on remediation, but then we must move on to establish a better system in future.

On whether remediation will be carried out effectively, we are going to put additional spot checks in across the system to make sure that where insulation faults have been remediated, that work has been done to the required standard. Suppliers have committed to additional checks and monitoring future installations of solid-wall insulation so that householders can be confident that it is done to a better standard. I very much agree that any householder who has learned about this issue will be concerned. They will be concerned about the impact on their home, but also about whether the remediation work will be done effectively.

In terms of information to those households, Ofgem has begun writing to all households that have had solid-wall installation installed under energy company obligation 4 or the Great British Insulation Scheme. As I said, we will be reviewing the quality of all 65,000 solid-wall insulations, and we hope that the vast majority will not have any issues or that any issues found will be minor, but if we see major concerns, we will want action to take place immediately. It is clearly important that we carry out a quality check across all solid-wall insulation under these schemes.

I want to pick up the issue of saleability raised by the noble Lord, Lord Teverson. Clearly, this will be a concern. Householders seeking to sell or perhaps remortgage their home will be worried about lenders’ approach. Our expectation is that the firms that have done this shoddy work must pay for the remediation. Clearly, that must be the principle under which we operate. There is a moral hazard in my saying anything different from the Dispatch Box on that issue.

Looking further ahead, it is clear that the whole system of consumer protection is fragmented and in need of reform. In terms of our overall goal towards net zero and the massive challenge of heating efficiency in our homes, it is essential that in all these programmes the public have confidence in the quality of the installation. That is why what has been discovered has been very disappointing, but we have to take it, look at the whole system and improve it.

17:54

[Lord Foster of Bath (LD)]

My Lords, I do not for a minute doubt the Government’s commitment to improving the energy efficiency of existing properties, and I know that they are well aware of the huge task that is ahead of them to meet the 2030 and 2035 targets. However, the Statement makes it very clear that yet more work will have to be done as a result of the problems described in it. Earlier today, I asked the noble Baroness, Lady Taylor, whether she could explain where the staff were going to come from to carry out this work. Now there is an additional problem to be dealt with. The noble Baroness made it very clear that the department is working closely with the Department for Education to develop solutions to this, not least through the apprenticeship scheme, but can the Minister give us a little more detail about what is actually going to arise as a result of those discussions, because many people are deeply concerned that we will not have the staff to be able to carry out the work that arises under this Statement, let alone the work that is urgently needed to improve energy efficiency in other homes?

[Lord Hunt of Kings Heath (Lab)]

My Lords, I was privileged to be by the side of my noble friend when we had that very interesting Question, because of course, although she answered it, the future homes standard very much concerns my department as well, which is why we are working so closely together. I think that she said that not only is the skills issue very much on her agenda but that her department is working closely with the Department for Education. Of course, my department has a huge vested interest in ensuring that we deal with any skills shortages. We are very focused on the supply chain. We are supporting the sector to obtain necessary qualifications to work in government schemes through our skills competition and exploring measures to ensure that installers are getting the right skills and experience to carry out high-quality installation. Clearly, this is one issue that must arise from what has happened: why installers do not seem to be able to do the right thing.

There is much that we are going to work on, but I would say on the positive side that if ever one wanted to make a connection between the growth agenda and the charge to net zero, this is it. A huge number of skilled jobs will be there to be filled in future. Our job in government is to facilitate the training and development that need to take place to respond to that challenge.

[Baroness Bennett of Manor Castle (GP)]

My Lords, the Minister just spoke about the possibility of a huge number of skilled jobs. He may be aware of the TUC’s recommendations from last year for the Government’s warm homes strategy. If we are going to train people in those skills, we have to make sure those are also good jobs. Those TUC recommendations include ensuring that these are high-quality jobs supporting direct employment, with strong procurement rules and adherence to nationally negotiated terms and conditions. One key thing we have seen in the past is that government policies have come and gone, people have got trained up and started businesses, then the money has gone away and those people have left the industry. The TUC is recommending a multi-decade national retrofit plan. Are the Government listening to what the TUC has to say on making sure those are good jobs for skilled people?

[Lord Hunt of Kings Heath (Lab)]

Actually, I agree with much of what the noble Baroness says. What the sector—and that includes trade unions and the people working in the sector—needs is certainty for the future. Indeed, to relate it to another low-carbon energy structure, nuclear, that is the message that we have been getting over the last three days. Obviously, we are still developing our plans and projects around the massive challenge of the decarbonisation of buildings. Clearly, we need to make sure that we provide the kind of certainty that the private sector needs to make the investment. We need to make sure that a supply chain is vibrant and that we have skilled people working in it. I should say that the whole energy industry, if I may put it that way, although it also relates to my noble friend’s responsibility, offers such potential for the future. It really is an exciting time to be thinking about what we need to do to provide what the noble Baroness has just said.

[Baroness Wheatcroft (CB)]

My Lords, the Statement says:

“We will put in place a robust system of compliance, audit and regulation, so that consumers have the confidence to take up the offer of upgrading their homes”.


Can the Minister say whether he thinks this was a failure of regulation? If so, can he reassure the House that the move to regulate or not regulate so that growth can be set free will not jeopardise schemes such as this and lead to more failure?

[Lord Hunt of Kings Heath (Lab)]

Actually, that is a very interesting question and the answer is yes. Clearly, the failure was in the hands of the companies that got the contracts to provide the services. They have been shown visibly to have failed. However, the regulatory system is a mishmash. There are too many bodies involved. There is confusion about who is responsible for what. The certification bodies can be in competition with each other. There is a risk, therefore, of a lowest common denominator approach. Clearly, we need to improve that, but what we want is not a huge amount of unnecessary bureaucracy but proportionate regulation. I think this can be done more efficiently and the public can have more confidence—and that actually is the Government’s view on regulation generally.

[The Earl of Lytton (CB)]

My Lords, the Minister has made several points that certainly chime with me. In a sense, we have been here before because of things such as electro-osmotic damp-proof courses, types of urea formaldehyde foam being put into wall cavities and, more recently, polyurethane foam being sprayed on the inside of roof slopes. All these firms seem to be task-and-finish jobs. I have been involved with this for probably nearly 50 years as a professional dealing with property and I have seen these people come and go and reappear in different guises. If one is going to have a system of regulation-lite and move to individual responsibility, I get that up to a point, but there is not the penetration to make sure that that is constantly policed and enforced, and there is only one other option that is available to prevent people operating like spivs and charlatans, if I can put it that way—that is not to say all in industry are like that, but clearly some of them are—and that is to have a regime of strict liability at director and company level, in the same way as we had with health and safety, in order that they cannot escape the liabilities anything like as quickly simply by disappearing off and becoming insolvent. Would the Minister care to comment on that?

[Lord Hunt of Kings Heath (Lab)]

My Lords, I am grateful to the noble Lord because he speaks with such expertise in this area. In a sense I should have reflected on that in my answer to the point made by the noble Lord, Lord Teverson. I am not going to commit myself in terms of what the future is going to look like, but I will take his remarks and make sure my ministerial colleagues see them. As I said, our first task must be remediation and responding to the concerns of 65,000 people who will be very concerned. Obviously, they are going to get the letter from Ofgem; some of them are already getting it. We will then be reflecting very much on how we need to develop a more robust system.

I, too, have experience. I remember being a Minister in the Department for Work and Pensions when King’s College reviewed the work of gas installers, and, again, they found a great number of problems. As a result, the whole gas regulation process was shaken up. So we have to look at these things very seriously, because the credibility of the net-zero programme and the decarbonisation of our homes depends on public trust. If we cannot gain the public’s trust, they will not take the necessary action, so we really have to work hard on this.

[Viscount Thurso (LD)]

My Lords, further to the answer the Minister gave to my noble friend Lord Foster regarding skills, I sit on the Industry and Regulators Committee and we had a very good presentation regarding the Government’s skills strategy and the formation of Skills England, but there was some concern expressed as to whether sufficient weight would be given to those in the construction trades, which is where many of those who are required will come from. I hope that the Minister and his ministerial colleague will put some pressure on Skills England to make sure that those skills are given the weight they should have, because without them we will not get the benefits of growth in that industry.

[Lord Hunt of Kings Heath (Lab)]

My Lords, I agree with the noble Viscount. I will take that away in terms of the work we are going to be doing. Within the energy sector there are some fantastic examples of industries that really have invested in skills and training. To take EDF as an example and looking at Bridgwater and Taunton College, where it has invested hugely and where the quality of education and skills training is phenomenal, I say that it is things like that I would like to see across the whole sector.

[Lord Grantchester (Lab)]

I welcome the determination to correct this and put the situation right. I am concerned over the effect of this on public confidence in TrustMark and undertaking home improvements. Regarding retrofitting, householders used to be able to approach with confidence the charity Carbon Trust as a one-stop for advice on energy home improvements. It was extremely helpful in giving independent guidance to householders on the necessary measures for upgrading the energy efficiency of their homes. Will the Minister look at how such advice might be made available again?

[Lord Hunt of Kings Heath (Lab)]

My Lords, I think my noble friend is hinting at whether there is a one-stop shop. The answer is no, there is not. Obviously, we have a number of agencies that provide very helpful advice, including the Energy Saving Trust, Citizens Advice and National Energy Action. In the immediate aftermath of what has happened, Ofgem, in addition to sending letters out, will have a helpline and contact details. The point the noble Lord raises is an important one and we will be looking at this as part of our review of the general arrangements.
