Question to the Department for Business, Energy and Industrial Strategy:

To ask the Secretary of State for Business, Energy and Industrial Strategy, whether he has made an assessment of the implications for his policies of the findings of DELTA-EE’s whitepaper, published on 26 October 2021, on the potential for reducing the cost of installed heat pumps.

The findings of Delta-EE’s white paper support existing evidence in demonstrating the potential for reductions in the installed cost of heat pumps. As made clear in the Government’s Heat and Buildings Strategy, published in October 2021, growing the number of heat pump installations to at least 600,000 a year by 2028 is contingent on the market finding ways to reduce the upfront cost of the systems. The Government has commissioned further research on this issue and will publish its conclusions later this year.
