Domestic Heat Pumps: Budget Underspend

Lord Greenhalgh Excerpts

Tuesday 28th February 2023 Lords Chamber

[Lord Callanan (Con)]

I thank the noble Lord for a question not at all related to heat pumps. He makes a valid point: the price cap has been reduced in line with the reduction of wholesale prices. At the same time, there is a gap in funding because of government support. We have—the taxpayer has—been paying about one-third of people’s energy bills through the winter. That support is unsustainable in the longer term and is starting to be withdrawn, but I am sure the Chancellor is looking at this very closely.

[Lord Greenhalgh (Con)]

My Lords, is it not fair to say that implicit in the last two Questions is the rather disappointing uptake in the number of homes putting in heat pumps? I declare that I put in a gas boiler recently and got change from £5,000. Have the Government done any work on the point raised by my noble friend Lord Forsyth on the cost for the average punter to change their home? The reality is that the markets determine what people put in. We need to look at the actual cost of installing a heat pump. If we imagine a scenario where 10% of new builds have heat pumps and the retrofit programmes go in great guns, what would it cost to install one of these things? Have we got research? If the Minister cannot answer me directly at the Dispatch Box, will he please write to me with a detailed response?

[Lord Callanan (Con)]

I can answer my noble friend directly: we have done lots of research on these matters. I will give him a couple of examples of existing offers. British Gas has a starting price for an air source heat pump of £2,999 and Octopus Energy is offering one for £2,500 including the upgrade grant that we are offering. It obviously depends on the circumstances of the property. There are huge number of variable factors, such as how many radiators you need—whether your existing radiators can be reused will depend on their size. There are a lot of different factors to take into consideration, but his point is ultimately valid, in that we have to make sure that the prices of heat pumps come down over time. As consumers get more used to them and volumes go up, I think that they will.
