Conclusion (the committee's words)
Decarbonising electricity generation is crucial to the government’s net zero strategy, including decarbonising home heating. If, as the government expects, most homes switch their heating systems to heat pumps or heat networks, it is important that these are powered by clean sources of electricity to achieve decarbonisation. In 2021, the government set an ambition that by 2035 all electricity should be generated using clean sources, subject to security of supply, while meeting an expected increase in electricity demand of up to 60%. This means phasing out polluting types of electricity generation, such as gas-fired power stations and replacing them with a new mix of zero and low-carbon generation, including wind, solar and nuclear power.73

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.
