Conclusion (the committee's words)
DESNZ clarified that it was “working on making the Government digital offering in this space much better”. It added that it signposted to digital companies that helped households to calculate running costs and lifetime costs via gov.uk. It recognised, however, that there was a role for it to do more. It also explained that it mitigated the risk of poor installations by requiring Microgeneration Certification Scheme-certification for all heat pump installations funded through the Boiler Upgrade Scheme.31 29 Q 31; DHH0015 30 Q 33; DHH0026; C&AG’s Report, para 2.16 31 Qq 31–32, 34, 37, C&AG’s Report, para 3.14 14 Decarbonising home heating 2 Increasing heat pump installations Training installers

Government response
The government responded to the whole report on 11 July 2025 (deadline 26 July 2024).
Summary written by Accountability Index from the government's response. It is not the government's own words.The government states that it agrees with most of the Committee's recommendations on decarbonising home heating, some with target dates still "to be confirmed", and disagrees with one, on gas network decommissioning.
- On heat pump running costs, the government agrees with the recommendation, but implementation is "dependent on further steers from new ministers" and no date is set. It says it "is considering" the best way to bring costs down.
- On installer numbers, the government agrees, with a target of Summer 2025. It says decisions on future training support "will form part of Spending Review 2025 (SR25)", as the Heat Training Grant is funded until April 2025.
- On data, the government agrees to publish quarterly data on retrofit installations using government funding, with a target of Winter 2024. It "cannot commit" to publishing data on new builds or unfunded installations "until a suitable mechanism is found".
- The government disagrees with the recommendation to set out gas network decommissioning arrangements by end-June 2025, saying a full assessment "will require more time". It says it is "currently exploring ways" to facilitate the transition.
