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

To ask the Secretary of State for Business, Energy and Industrial Strategy, what his timescale is for the full delivery of heat pumps; and what estimate he has made of how many homes will receive a heat pump each year.

In order to meet Net Zero by 2050, virtually all heating will need to be decarbonised. Given the diversity of heat demand, a mix of technologies and customer options will be needed to decarbonise heat at scale.

As part of my Rt. Hon. Friend the Prime Minister’s Ten Point Plan, the Government is aiming to reach 600,000 heat pump installations per year by 2028. This ambition is in line with the minimum market capacity that the Government anticipated needing for all eventual pathways to decarbonise heating in buildings by 2050. The Government is drafting a range of policy measures to best support the market with this trajectory.

A transition to predominantly electric heating would require deployment to increase beyond 600,000 heat pumps per year by the early 2030s. In the Net Zero Strategy, the Government stated that, in this scenario, deployment would need to increase up to 1.9 million per year from 2035.
