Written question asked by Andrew Snowden (Conservative) on Friday, 5 June 2026, in the House of Commons. It was due for an answer on Tuesday, 9 June 2026. It was answered by Katie White (Labour) on Monday, 15 June 2026 on behalf of the Department for Energy Security and Net Zero.

Natural Gas: Boilers

Question: To ask the Secretary of State for Energy Security and Net Zero, what estimate he has made of the number of households that will be required to replace a gas boiler before the end of its natural lifespan in order to meet Carbon Budget 7.

Answer: We have been clear on several occasions that we will not force anyone to rip out a working boiler to deliver our carbon budgets, including in the Warm Homes Plan that we published earlier this year. Instead, this Government is focused on incentivising moves to cleaner, affordable heating and making this attractive and easy for the public.   Our Warm Homes Plan supports investment in heat pumps and other energy efficiency upgrades to help cut bills.
