Home Insulation

Martin McCluskey Excerpts

Wednesday 26th November 2025 Westminster Hall

[The Parliamentary Under-Secretary of State for Energy Security and Net Zero (Martin McCluskey)]

It is a pleasure to serve under your chairmanship, Mr Dowd. I thank all hon. Members for their contributions today, and I thank particularly my hon. Friend the Member for Shipley (Anna Dixon), not only for securing the debate, but for all her work on the Public Accounts Committee in scrutinising the ECO4 scandal. Over the last few months, she has fought extremely hard for her constituents who have suffered from substandard insulation through Government schemes.

When I came to this brief, about 10 weeks ago, I was presented with the outcome of the National Audit Office report. I was shocked by the extent of the failures under the previous Government, by the system that we inherited and by the many personal stories of people impacted by damp, mould and other issues.

Homes hold a special place in people’s hearts. They are places that we pour time and money into. We make memories in them. They are sanctuaries, shelters, places of care and settings for our lives. People will not put their homes at risk unless they can be absolutely sure that things will not go wrong—or that, if they do, they will be put right. That is why we are making consumer protection reform such a central part of the upcoming warm homes plan.

Just a few months into this new Government, widespread cases of poor-quality insulation were identified under the ECO4 and Great British insulation schemes. The Government, including both me and my predecessor, have spoken extensively about our actions on this. To give hon. Members reassurance, those include enhanced checks and oversight of contractors and TrustMark; new restrictions on installers operating through the multiple certification bodies we have; updated standards for retrofit co-ordinators and designers; and an offer of a comprehensive on-site audit to every household with external wall insulation installed under those two schemes, at no cost to the consumer. I see hon. Members present who I know are advocated for constituents facing particular problems with ECO4; they will all be receiving notices of audits, or maybe they have already. I encourage hon. Members to make sure that their constituents take up that offer of an audit, because that is the gateway to remediation.

[Anna Dixon]

I thank the Minister for the reassurance that householders affected by faulty work will be getting an audit and that there will be remedies. Can he confirm when those letters will be going out, if they have not already, and whether they will be from Ofgem?

[Martin McCluskey]

The letters will be sent, I think, from today. Many of those households will already have received knocks on the door or possibly direct contact from scheme providers. We are clear that the system needs to remediate this in the first instance. The issue was caused by the system, and there are guarantees available through the schemes to ensure that they are remediated. If any Member is dealing with constituents whose audits are not getting done properly or who are having difficulty with the guarantee providers, I ask them please to come directly to me, because we need to know exactly what is happening as this action takes place.

Despite all the actions we are taking on ECO4, we still need to think about the future system. That is why we have committed to reforming the system and to accelerating that process. I can confirm that we are looking at the entire landscape of consumer protection, from how installers work in homes to where people turn for rapid action and enforcement if things go wrong. The Government are planning to consult on the specific proposals early in the new year, and are already working with industry and consumer protection experts to develop and stress-test plans, including through the retrofit system reform advisory panel, which was set up under my predecessor and began work in July.

As this is one of the most urgent challenges that the Government face in our mission to improve the lives of working people, my right hon. and learned Friend the Prime Minister gave me the clearest of instructions on my first day in the job: to reduce bills by making millions more homes warm, safe and fit for the 21st century. We face a number of challenges, as my hon. Friend the Member for Shipley alluded to. More than 80% of UK homes rely on gas for heating—among the highest percentages in the world, meaning that we are particularly exposed to crises or energy shocks, as we saw after the Russian invasion of Ukraine. Moreover, we have some of the oldest housing stock in Europe; more than a third of houses were built before the second world war, most with uninsulated walls, meaning that yet more money and fossil fuels are needed to heat them.

My hon. Friend mentioned a project in Saltaire, and I will be more than happy to visit. I have had good and constructive conversations with Members across the House regarding heritage retrofit. That is something we have to address in the new plan.

[Gareth Snell]

Stoke-on-Trent has some of the oldest housing stock in the country: brick-built terraces, single skinned and in some places still single glazed. A programme by the last Labour Government that made a real difference was the housing market renewal programme, which ran up until 2010 and then was unceremoniously guillotined by the incoming Tory Government. It was able to retrofit housing in a style that matched the local communities, but it was done with communities as part of a more progressive regeneration programme. It meant that houses were better looking and warmer, they lasted longer and residents wanted to live there. Why the Tory Government got rid of it I do not know, but it is something the Minister might want to look at for future ideas.

[Martin McCluskey]

I would be more than happy to look at that. I have been working to help develop the warm homes plan and am looking particularly at area-based approaches; one of the most effective is when entire communities and neighbourhoods are upgraded at once. The effect is much larger, and neighbours can see the impact on their bills, which helps to spread the benefit.

The warm homes plan will set out in more detail how we are going to meet the challenge addressed in this debate. We have been working hard behind the scenes to get it right and will publish it in full soon. We have been clear from the moment we came into government about the scale of the ambition. My hon. Friend mentioned £13.5 billion; after the Budget today that number is actually £15 billion, and we have extended our ambition to upgrade 5 million homes.

As a student of history, I think of the first Labour Government in the 1920s with their housing Act—the Housing (Financial Provisions) Act 1924—which upgraded and subsidised half a million homes. What we are trying to do with the warm homes plan is 10 times that. That is the level of ambition we have. It means entire streets and whole neighbourhoods benefiting from solar panels, heat pumps, home batteries and better insulation. We have already kick-started that. We are not waiting for the plan to get on with delivery. We have allocated £1.8 billion through the warm homes local grant and warm homes social housing fund. We have set out proposals to increase minimum energy efficiency standards in the private rented sector in England and Wales to EPC C or equivalent by 2030 and introduced a minimum standard in the social rented sector, which is incredibly important for many of our constituents. Those measures, combined, will lift hundreds of thousands of households out of poverty.

For homeowners, we are making it cheaper and easier to install a heat pump. To the point made by the hon. Member for Strangford (Jim Shannon), we announced the extension of the boiler upgrade scheme to new technologies last week, and we have an ongoing consultation on alternative technologies. We have doubled the funding for the boiler upgrade scheme to £295 million this year and, because of decisions made by my right hon. Friend the Chancellor in the Budget, we will be increasing it year on year up to 2030. Just this month, as I said, the expansion has meant that we are able to extend the scheme to air-to-air heat pumps, a technology that I know many of our constituents were calling on the Government to make a change on last summer.

While we deliver the plan, we know there has to be short-term as well as longer-term action. That is why we have expanded the warm homes discount this year to every household where the billpayer is on a means-tested benefit. That is £150-worth of support directly to billpayers this winter. My hon. Friend the Member for Stoke-on-Trent Central (Gareth Snell) mentioned Beat the Cold; I met Fiona Miller yesterday and had a very good conversation with her about the work she is doing on data sharing between the NHS and her organisation. That is something I want to look at, and I am keen to visit Stoke-on-Trent Central to see in person the work that Beat the Cold is doing.

All those action that are taking place are good in the short term, but how do we tackle the cost of living and bring energy bills down for good? In the long term, we do that by pushing for our target of clean power by 2030: clean power generated in Britain, which we control and which will end the rollercoaster of energy bills that, bluntly, are at the moment decided by dictators and upheavals beyond our borders. We do that by upgrading homes with electrified, energy-efficient technologies, putting people in a position to benefit directly from clean, secure, affordable energy.

My immediate focus remains on some of the issues that we have heard about today, and on the people across the country living in homes that they can barely afford to heat. As we enter another winter, people should not have to choose between heating and eating. A large part of the reason the Chancellor took the action that she took in today’s Budget is that she wants to stop people having to make those incredibly difficult choices. When we publish it, the warm homes plan will set out our path to a future that we all want to see. We want warmer homes, no matter where we live or whether we rent or own—homes that are smarter, cheaper to run and greener, and are protected by a system that keeps them free of damp, mould and other issues. I welcome this debate, and I again congratulate my hon. Friend the Member for Shipley.

Question put and agreed to.
