Conclusion (the committee's words)
Several written submissions to our inquiry highlighted that uncertainty over the role of hydrogen is delaying key decarbonisation investment decisions until government makes a decision on hydrogen. Hydrogen UK, for example, told us that the decisions about trials and recent announcements had “created ambiguity in the role of hydrogen in domestic heating”. It explained that clarity around the role of hydrogen was needed to “enable industry stakeholders to make informed decisions, commit to necessary investments, and drive forward the innovation and infrastructure development required”.59 Similarly, a climate change think tank, E3G, suggested that industry was “suffering” from a lack of clarity regarding government’s “indecisiveness” on the future role of hydrogen for domestic heating.60 The MCS Foundation also told us that businesses, installers and manufacturers will be reluctant to invest in skills and technologies if there is a risk than in later years the government will focus on hydrogen rather than electrified solutions.61 Good Energy further indicated that manufacturers of heat pumps and heat network developers require “affirmative signals” over the future of hydrogen for heating.62

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.
