My Lords, here we have it: 32 pages of regulation to introduce something that some would consider a mere mouse in terms of its impact on this market. After all, it introduces a £500 fine for selling each excess gas boiler, relative to the proportion that is prescribed in the regulation. That £500 is actually quite big relative to the cost of a gas boiler, which is typically around a couple of thousand pounds, even though it is relatively small relative to the cost of a heat pump. None the less, I ask the Minister this: will that £500 fine, which then becomes a marketable instrument, be available to importers? If I have correctly understood how the system will work, someone who exports to this country heat pumps from abroad could sell the certificate that this measure will give them to a domestic producer who has not sold enough electric heat pumps for up to £500—that is a jolly nice subsidy for importers of heat pumps into this country, even if it is not massive.
It is expected that this measure will raise the number of heat pumps sold from roughly 40,500 last year, nearly 3% of the boiler market, to 77,000 pumps—6% of the expected market this year. That is not a huge increase. The Minister said that last year, without the benefit of this measure, the number of heat pumps sold increased substantially. So it will not be a huge increase in the coming year. Why do we think this measure is necessary if these things are proving so attractive and the market is growing anyway? Can the Minister confirm that the 6% target is what is introduced, and that it will continue and persist unless and until he introduces, via further legislation—I also ask him to confirm that this will require further legislation—a higher target?
Failing the introduction of a higher target, any future growth in the market will depend on hopes on the cost of heat pumps coming down as manufacturers find more efficient ways of making them. When I was still in the House of Commons I had a meeting with Octopus Energy, which reckoned that the materials involved in making a heat pump cost about £2,000. Obviously, a huge amount of processing goes into making a heat pump, but it suggested that the potential for bringing down the cost over time was significant. One hopes that will happen. Failing that, the only other thing—we are stuck with the 6% target and this £500 fine—will be the lure of subsidies for consumers to buy heat pumps instead of fossil fuel boilers.
The costs and benefits of the whole procedure are spelled out in the impact assessment. It says the net present value of the costs involved is £195 million. The benefits were put at £220 million, of which those that result from the main purpose of the operation, to reduce carbon, were less than the costs. The total benefit is above the costs only if you allow for the impact it will have on cleaner air. As well as reducing the amount of CO2, which is a very clean thing that we breathe all the time, the reduction in the other impurities put in the air by fossil fuels just about brings it to a net benefit. We are talking about the costs and benefits being roughly the same order of magnitude. Once again, an almost religious fanaticism, which does not take the costs and benefits into account, is driving this policy.
I will make a few observations about the situation in France, because I have a house in France and I observe what is happening there. Two of my French neighbours have installed heat pumps. One in a comparatively small cottage cost over €20,000—not for the pump but for the insulation—all paid by the French taxpayer. Bully for him. Another friend has a rather more substantial old house. It cost the French taxpayer €100,000 to install the heat pump and the necessary insulation. In his case, it would not work for a year because the installers were so busy—because it is free to users—that they would not come back and tell him how to make it work. It took him a long time to find anyone who would. I noticed, when I went round to enjoy his hospitality over the new year, that he had wood fires burning as well.
I sincerely hope that we do not go down the path of subsidising something at the huge costs that the French taxpayer is having to absorb, when the costs and benefits of the whole process, even without subsidies, are so marginal. We do not want to put ourselves as near bankruptcy as the French state is.
