The short answer
As of September 2026 there is no law stopping you repairing or replacing a gas boiler in an existing home, and nobody is being forced to rip out a working one. What is law is the Future Homes Standard, which from 24 March 2027 requires new homes in England to be built with low-carbon heating. The 2035 date you may have read about was only ever an ambition, never legislation, and the current Warm Homes Plan sets no end date for boilers in existing homes. Hydrogen-ready boiler rules depend on a government decision on hydrogen heating that had not been published at the time of writing.
Can I still replace my gas boiler with a new one?
Yes. Fitting a new gas boiler in an existing home in England is legal in 2026, provided the work meets Building Regulations. Under Approved Document L, a replacement gas boiler must reach at least 92% ErP efficiency, and a new combi must come with one extra efficiency measure, such as weather compensation or a smart thermostat with automation and optimisation. Repairs are equally unrestricted.
What is actually law, what is proposed, and what is speculation?
| Policy | Status | What it means for you |
|---|---|---|
| Future Homes Standard (new homes, England) | Law. Building Regulations amended by SI 2026/335; in force 24 March 2027 | New homes must have low-carbon heating and on-site renewable electricity. It does not apply to existing homes or replacement boilers. |
| Minimum 92% efficiency for replacement gas boilers | Building Regulations requirement, with the figure set in the official guidance, Approved Document L | Any new gas boiler must be a high-efficiency model. |
| Boiler Upgrade Scheme | In force. Grants of £7,500 for air and ground source heat pumps, funded to 2030 | Help to switch if you choose to. Voluntary. |
| Ending new gas boiler installs 'from 2035' | Ambition only (2021 strategy, restated 2023). Never legislated. Not set out in the 2026 Warm Homes Plan | No legal effect today. |
| Hydrogen-ready boilers from 2030 | Conditional. Only if the government decides hydrogen will play a substantive role in heating | No requirement unless and until that decision is made and regulations follow. |
| A date when existing boilers must be removed | Does not exist | Speculation. Ignore any claim otherwise. |
What does the Future Homes Standard change, and when?
The government published the Future Homes and Buildings Standards on 24 March 2026, with the regulations coming into force on 24 March 2027. The government's stated aim is that new homes have low-carbon heating, high levels of energy efficiency and, in most cases, solar panels as standard, so they will not need retrofitting later. A new functional requirement makes on-site renewable electricity generation part of the rules for new dwellings.
- It applies to new homes and new non-domestic buildings, not to work on the home you already live in.
- There is a transition period. The old rules can still apply where building control notices or applications went in before 24 March 2027, as long as building work starts before 24 March 2028.
- Higher-risk buildings follow a slightly later timetable, from 24 September 2027.
So a new-build approved under the new rules will come with low-carbon heating, typically a heat pump or a heat network connection, rather than a gas boiler. Homes still finishing under the transition period may not. If you live in an existing house, nothing in the standard touches your heating.
Where did the 2035 date come from, and does it still stand?
The October 2021 Heat and Buildings Strategy set an ambition to 'phase out the installation of new natural gas boilers beyond 2035', once the costs of low-carbon alternatives had come down, and said no one would be forced to remove existing boilers. In a speech on 20 September 2023, the then Prime Minister said households would only need to switch when replacing a boiler, not before 2035, and announced an exemption for the households who would struggle most to switch, which the government expected to cover about a fifth of homes.
Neither the ambition nor the exemption was ever turned into law. The Warm Homes Plan, published on 21 January 2026, does not set a phase-out date for gas boilers in existing homes. Its approach is to make heat pumps 'the desirable and natural choice for households replacing an existing heating system at the end of its life', through grants, low-interest loans and lower electricity costs, while the Future Homes Standard covers new-builds.
What is the Warm Homes Plan, and does it affect my boiler?
The Warm Homes Plan is the government's £15 billion package for home upgrades. If you own your home, it is almost all incentives rather than rules.
- £2.7 billion for the Boiler Upgrade Scheme to 2030, keeping the £7,500 heat pump grant and adding £2,500 for air-to-air heat pumps.
- A new zero and low-interest loan offer, backed by an initial £2 billion.
- £5 billion for low-income schemes.
- An aim of more than 450,000 heat pump installations a year by 2030.
Separately, until March 2027 off-gas-grid homes replacing oil or LPG heating can get an extra £1,500 on top of the £7,500, making £9,000. Landlords face tighter rules through the confirmed move to EPC band C by 1 October 2030 for private rentals, which still needs legislation to take effect. None of this obliges an owner-occupier to change a gas boiler. You can check the grant against your own home with the BUS eligibility checker, and the Boiler Upgrade Scheme explained covers the detail.
What about hydrogen and 'hydrogen-ready' boilers?
In March 2024 the government said it planned to decide in 2026 whether, and how, hydrogen will contribute to heating. It also said that only if it decides hydrogen will play a substantive role would it require domestic gas boilers to be hydrogen-ready, and then only from 2030.
The most recent position we could find on GOV.UK is more cautious. The Warm Homes Plan concentrates on 'proven electric technologies', says hydrogen 'is not yet a proven technology for home heating', and that any role 'would come later and likely be limited'. The government's hydrogen heating overview, updated 24 March 2026, says it will consult in due course on its assessment. We found no published decision as of 17 September 2026.
In practice: do not pay extra for a boiler because it is described as hydrogen-ready, and do not delay a needed replacement waiting for hydrogen.
So what should you do if your boiler is ageing?
- If it works and is safe, keep it serviced. Nothing requires you to act.
- If it is failing, work through whether to repair or replace first.
- If you replace, price both options: an efficient gas boiler (see the instant boiler quote) and a heat pump with the £7,500 grant.
- Think long term. New homes built to the Future Homes Standard will have low-carbon heating, and your heating system shows on your EPC, but no removal date exists for existing homes.
- If you are unsure, plan the whole house so insulation and heating decisions happen in a sensible order.
Common questions
Are gas boilers being banned in 2025, 2026 or 2035?
No ban applies to existing homes. From 24 March 2027, new homes in England must be built with low-carbon heating under the Future Homes Standard. The 2035 date was an ambition that was never legislated, and the January 2026 Warm Homes Plan does not set one.
Will I have to remove my gas boiler when I sell my house?
No. There is no requirement to remove or replace a boiler on sale. A buyer will see your EPC, which reflects your heating system, but that is information, not an obligation.
Can I get a grant for a new gas boiler?
Not through the Boiler Upgrade Scheme, which only funds heat pumps and, in limited rural cases, biomass boilers. Gas boilers are also standard-rated for VAT, while heat pumps are zero-rated until 31 March 2027.
Should I buy a hydrogen-ready boiler just in case?
There is no need to. The government has not decided that hydrogen will be used for home heating, and has described any future role as likely to be limited. Choose a boiler on efficiency, warranty and fit for your home.
