Clean Heat Market Mechanism Regulations 2024

Earl Russell Excerpts

Monday 20th January 2025 Grand Committee

[Baroness McIntosh of Pickering (Con)]

I am grateful to the Minister for setting out the contents of the regulations before us. I am afraid that I share some of the scepticism of my noble friend Lord Lilley. I am grateful to the noble Lord, Lord Hunt, for referring to the warm homes scheme. He is aware of my disappointment that the discount is not going to be revisited, and I say that as honorary president of National Energy Action.

My understanding is that the heat pumps that are the subject of this measure simply are not as efficient as oil-fired central heating. I say that as where I live in the north of England, it is all oil-fired central heating; we are off grid and we cannot use gas. I walked past a surgery in the north of England that did not have just one heat pump; it had fitted three heat pumps, which probably means that one heat pump was not sufficient to generate the heat required.

My understanding—and I would be grateful if the noble Lord, Lord Hunt, could confirm this—is that, without log fires or some other secondary heating, heat pumps heat only to a top temperature of about 16 degrees. If you are retrofitting an existing building, as many of the windows may not be able to accommodate the size of the heat pump or the radiators that connect to it, substantial renovation may be required.

Furthermore, I am grateful to the Secondary Legislation Scrutiny Committee, which highlighted that the starting point referred to by the noble Lord, Lord Hunt, of around 40,500 installations per year is—in its word, at paragraph 56 of its 10th report—“ambitious”. The department expects the scheme to help ensure the installation of at least 77,000 heat pumps a year in existing homes between 2024-25 and 2028-29. I ask the Minister a simple question: is that feasible and realistic?

My noble friend Lord Lilley quoted £2,000 as the cost of an ordinary boiler. I recently got two quotes for a boiler. The boiler itself was not the issue. For the fitting, even that of an oil-fired boiler, you are looking at something in the region of £8,000 to £10,000. I repeat: if you live off-grid in a very rural area, it would be nice to think that heat pumps were an alternative, but, given the state of the current market, I just do not see them as feasible if they heat up to only 16 degrees when, in just the past two weeks, we have regularly had temperatures of freezing or down to minus 10. With those few remarks, I press the Minister to comment on these queries.

[Earl Russell (LD)]

My Lords, we are supportive of these regulations and the other actions that this Government have already taken—particularly in removing the outdated 1-metre rule on the requirement for planning permission—since coming into office. We are hopeful that, taken together with the other measures that the Government talk about, these measures will help us begin to make progress towards the target of 600,000 heat pumps by 2028 and help us to fulfil the need to meet these same figures every year going forward.

There are both supply-side actions and demand-side actions in this SI. We feel that the combination makes some valuable reforms. Most of all we welcome the work that has been done with industry after listening to concerns, making some much-needed reforms and finding ways forward on these issues. Our worry, though, is that, as welcome as these changes in the regulations are, they may not be sufficient in and of themselves to deal with the scale of the problem. In making this point, I quote the conclusion of the House of Lords Secondary Legislation Scrutiny Committee, which has already been mentioned:

“The DESNZ expects the scheme to help ensure the installation of at least 77,000 heat pumps a year in existing homes between 2024/25 and 2028/29. We consider this, from a starting point of around 40,500 installations per year, to be ambitious”.


Before I turn to the SI, judging by the debate on this measure in the other House, a little background information would be useful.

These regulations amend and reform a system that the Conservative Government brought in but mainly failed to make work in practice. The last Government compounded these problems by failing to work alongside and with industry and others in order to find amendments to the proposals, such that industry itself was prepared fully to support them and get behind them. These problems then led to further internal discussions about the policy itself, which further derailed progress. This problem meant that the implementation never really got resolved and, as a result, we are a long way behind on these targets. In short, the Conservatives had clear targets for the installation of heat pumps but failed to deliver them.

I give this background only because the Conservative Opposition spokesperson appeared to disown or not acknowledge that this is a reform of their policy. It may be that the Conservative policy has changed. If that is the case, I hope that the Conservative spokesman can make that clear.

[Lord Lilley (Con)]

They are of course three times more efficient on average—though not necessarily in cold weather. But electricity is four times as expensive as gas per therm.

[Earl Russell (LD)]

I welcome the intervention and will come back to the noble Lord on his point. During this transition, it will take a huge effort across government and beyond—and beyond the scope of this instrument—to meet the scale of these changes.

The regulations establish the new UK-wide heat market mechanism to promote the development of the market for retrofit installations of heat pumps in existing buildings. The CHMM is to launch on 1 April 2025 and run for an initial period of four years. In the interests of time, I will not go on too much, but there are two big changes from previous proposals. First, they propose to reduce the payment in lieu of any missing heat pump credits to £500 from the first year from the £3,000 proposed by the previous Government. Secondly, the period over which boiler sales are counted has been delayed to give the obligated parties more time to prepare. The Government have said:

“As set out in the consultation response published in November … We have also aligned the periods over which boiler sales and heat pump installations will generate obligations and credits, respectively, providing manufacturers with more time to prepare”.—[Official Report, Commons, Second Delegated Legislation Committee, 13/1/25; col. 4.]


The big change is that the new Minister has engaged and listened to industry and has managed to make some of the adjustments required by working in partnership. This approach has been welcomed by industry. Removing penalties and allowing more time is pivotal to finding common solutions. The approach of giving manufacturers more time to scale up the supply chain and expand sales without penalising customers is good and needs to continue while hitting some very ambitious and fast-approaching targets.

The ongoing relations with manufacturers and industry are clearly key to delivering this policy. How do the Government intend to continue these better relations while making sure that targets are met and that unnecessary costs are not passed on to consumers? I want to make it clear that this is not a boiler tax. The Conservatives, when this was their policy, were very keen that those words were not used to describe it.

Review mechanisms and relations with industry are crucial to delivering this policy. I note that any adjustments would require further legislation and that would change the whole impact assessment. Any increases in the target in future schemes would require further secondary legislation. I note that the Government have said that they will not force consumers and that this is about working in partnership. My worry is about the confidence that the Government have in the ability to deliver the volume of heat pumps required in the time available.

I would like briefly to ask the Minister about some wider points. The cost of getting a heat pump is still a barrier to entry. I welcome the fact that the Government have continued the £7,500 grant, which, to their credit, the Conservatives not only introduced but increased. Since that increase, we have had a remarkable uptake in the number of heat pumps. But, as we have heard, installing a heat pump is about a system-wide change. It is more than just installing a heat pump; often it involves under-floor heating and changing radiators. On average, this seems to be costing consumers at least an additional £5,000.

We have had some conversations as part of the GB Energy Bill about green mortgages. Are the Government considering finding ways that the additional costs, not just of heat pumps but other renewable energy technology, can be added to mortgages? Quality and innovation are clearly important as well, as is making sure that these are good-quality products.

The noble Lord, Lord Lilley, intervened on electricity market reform, and to some extent I agree with him. Our electricity is still very expensive—some of the most expensive in Europe. The Government’s policy is to get people away from gas and on to electricity. What plans do they have to make sure that electricity is affordable and to introduce social tariffs for those struggling to pay their bills?

On disinformation, misinformation and ignorance, according to the Government’s own policy document, only 51% of people in the UK know about heat pumps. There is disinformation and misinformation in this space—for example, that heat pumps do not warm our homes enough—so it is important that the Government have a strong public information campaign for the take-up of heat pumps, about what they are, how they work and what they do.

Finally, heat pumps can save the average household £300 a year, so they would go a long way towards Labour meeting its manifesto pledge. I wish the Government well, but these things are complicated.
