Heat Pumps
The question
To ask the Secretary of State for Energy Security and Net Zero, what estimate he has made of the number of additional heat pumps installed in homes in the financial year 2025/26 as a direct result of the Clean Heat Market Mechanism.
Answered by Martin McCluskey
The Clean Heat Market Mechanism is designed to support the development of the retrofit heat pump market as a whole, alongside and complementary to other measures such as the Boiler Upgrade Scheme. There was a 24% increase in supported heat pump installations under the Boiler Upgrade Scheme in the year to March 2026 relative to the previous year.
The Government has outlined plans to carry out an evaluation of a range of policies supporting the home heating transition, including the Clean Heat Market Mechanism. This multi-year evaluation is in its inception phase and will produce findings reports in due course.
