The short answer, and the one most Sussex homeowners are looking for: no, gas boilers are not banned. As of 2026 there is no law preventing you from installing or replacing a gas boiler in an existing home, and no confirmed date by which that will change. If your boiler fails tomorrow, you can have a new gas boiler fitted, just as you always could.
That said, there are genuine changes happening to UK heating policy, and the headlines around them cause a lot of unnecessary worry. Here is an honest, jargon-free explanation of what is actually changing, what is not, and what it means for your next boiler decision.
Where did the "2035 gas boiler ban" come from?
You may remember headlines about gas boilers being "banned by 2035." This referred to a proposed target to phase out the sale of new gas boilers — but it was never written into law, and the government's current approach has shifted firmly towards incentives rather than bans. In other words, there is no legislated 2035 ban on gas boilers in existing homes, and there never was.
The direction of travel is to encourage lower-carbon heating through grants and support, not to force homeowners to rip out working boilers. For the foreseeable future, replacing a gas boiler with another gas boiler remains a perfectly legal and sensible choice.
What about the Future Homes Standard?
This is the change that is real — but it is widely misunderstood. The Future Homes and Buildings Standards were published in March 2026 and come into force in 2027, with new homes expected to fully comply from 2028.
The crucial point: the Future Homes Standard applies only to brand-new homes. It sets tough efficiency and emissions targets for new builds, which in practice means developers will fit heat pumps or connect to heat networks rather than gas boilers. It does not apply to existing homes. If you already live in your house, nothing about this standard requires you to change your heating.
What is the Clean Heat Market Mechanism?
The Clean Heat Market Mechanism is another policy that sounds alarming but does not target homeowners at all. It places obligations on boiler manufacturers to sell a growing proportion of heat pumps alongside their gas boilers, or pay a charge.
It is aimed squarely at manufacturers, not households. It is not a tax on you, and it is not a ban on buying a gas boiler. It may gently nudge boiler prices over time, but it does not stop you fitting one.
Are hydrogen-ready boilers the answer?
You may have seen "hydrogen-ready" boilers marketed as future-proof. Be a little cautious here. There is currently no national plan to convert the gas grid to hydrogen for home heating — the government's clear preference is heat pumps and heat networks, and the hydrogen town heating trials were dropped. A hydrogen-ready boiler is essentially a standard gas boiler today, so don't pay a large premium on the promise of a hydrogen future that may never arrive for domestic heating.
What if I want to move away from gas?
If you are ready to switch to low-carbon heating, there is financial help available. The Boiler Upgrade Scheme offers grants of up to £7,500 towards an air source or ground source heat pump (and up to £5,000 towards a biomass boiler in eligible off-grid properties) in England and Wales.
Heat pumps are not right for every property — they work best in well-insulated homes — but for the right home they are an excellent option. We cover the grants in more detail in our guide to boiler grants and the ECO4 scheme.
So should I still buy a gas boiler in 2026?
For most Sussex homeowners replacing an existing boiler, the answer is yes. A modern A-rated gas boiler is affordable, reliable, efficient, and entirely legal — and it will be serviceable for its full lifespan of 10 to 15 years and beyond. There is no risk of waking up to find your boiler suddenly outlawed.
If you are building a new home, or you are renovating and your property is well insulated, it is worth at least considering a heat pump and the grant that comes with it. But there is no need to make a panicked, expensive decision based on a ban that does not exist.
FAQ
Can I still replace my gas boiler in 2026?
Yes. There is no ban on installing or replacing a gas boiler in an existing home. If your boiler breaks down, you can have a new gas boiler fitted by a Gas Safe registered engineer exactly as before.
Will gas boilers be banned in 2035?
No 2035 ban on gas boilers in existing homes has been made law. The figure came from a proposed phase-out target for new boiler sales that was never legislated. Current policy focuses on incentives for low-carbon heating rather than bans.
Does the Future Homes Standard mean I have to remove my gas boiler?
No. The Future Homes Standard applies only to new-build homes from 2027–2028. It places no requirement on existing homes, so your current gas boiler and any future gas boiler replacement are unaffected.
Should I pay extra for a hydrogen-ready boiler?
Generally, no. There is no confirmed plan to convert the gas grid to hydrogen for domestic heating, and a hydrogen-ready boiler functions as a normal gas boiler today. We would not recommend paying a significant premium for the hydrogen label.
Is a heat pump a good alternative to a gas boiler?
For a well-insulated home, a heat pump can be an excellent, low-carbon choice, and the Boiler Upgrade Scheme offers up to £7,500 towards one. For many existing Sussex homes, however, a new A-rated gas boiler remains the most practical and cost-effective option. We are happy to give you honest advice on what suits your property.
