Conclusion (the committee's words)
We are concerned that there is too much complexity and potential confusion for households to enable them to make informed decisions about installing a heat pump. Households can face complex decisions when looking to install a heat pump. For example, DESNZ is removing a requirement to have minimum standards for properties to have loft and cavity wall insulation in order to be eligible to apply for a grant through the Boiler Upgrade Scheme. It is instead leaving this as a choice for householders, but has not made available any additional evidence about how this choice will impact on energy bills. DESNZ accepts that it needs to undertake a fair bit of myth busting about the quality of the consumer experience when living with a heat pump. Households also need to identify a skilled installer and to do this they need proper information to decide where to spend their money. But many are unsure where to get impartial advice on making improvements to reduce their homes’ emissions. Recommendation 2: DESNZ should, as part of its Treasury Minute response, set out how it will make the heat pump landscape easier for consumers to navigate, for example being clear on the impact of insulation on energy bills, by directly comparing heat pump running costs in homes with and without insulation, with this information provided through an easy-to-use website. 6 Decarbonising home heating

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.
