The 2035 Gas Boiler Ban
What UK Homeowners Actually Need to Know
The 2035 ban affects new-build homes only. Your existing home is not affected. Here is everything you need to know, explained without spin.
Updated April 2026
The Key Point
From 2035, new-build homes in England cannot be fitted with gas boilers as the primary heating system. Existing homes are exempt. You can still buy, install, repair, and replace a gas boiler in your current home after 2035. There is no forced switchover for existing properties.
What the Law Actually Says
The Future Homes Standard requires that new homes built from 2025 onwards produce 75-80% fewer carbon emissions than current Building Regulations allow. In practice, this means most new-build homes will have heat pumps or other low-carbon heating.
From 2035, the government has committed to ending the installation of new gas boilers in new-build homes entirely. This is part of the UK's legally binding commitment to reach net zero by 2050.
The Clean Heat Market Mechanism, starting in 2028, will require boiler manufacturers to sell a minimum proportion of heat pumps alongside gas boilers. This is designed to scale up heat pump production rather than ban gas boilers outright.
Key Dates
Future Homes Standard takes effect for new builds. New homes must produce 75-80% fewer emissions.
Government decision on hydrogen for home heating expected. BUS grant extended with new £2,500 air-to-air category.
Clean Heat Market Mechanism starts. Manufacturers must sell a proportion of heat pumps.
No new gas boilers in new-build homes. Existing homes continue as normal.
Net zero target. Government aims for most homes to have low-carbon heating by this date through incentives.
What This Means for Existing Homeowners
Nothing changes for your current home. You can continue to use, repair, service, and replace your gas boiler after 2035. Gas engineers will continue to be trained, parts will continue to be manufactured, and the gas network will continue to supply homes.
The government's strategy for existing homes relies on incentives rather than mandates. The Boiler Upgrade Scheme (BUS) grant offers £7,500 toward a heat pump. ECO4 provides free boilers for eligible households. The aim is to make low-carbon heating attractive enough that homeowners choose to switch, not to force them.
There are approximately 23 million homes with gas central heating in England alone. Forcing all of them to switch would be politically and practically impossible. The transition will take decades, not years.
Hydrogen-Ready Boilers
A hydrogen-ready boiler runs on natural gas today but can be converted to run on 100% hydrogen if the gas network switches to hydrogen in the future. The conversion involves swapping a few internal components, typically taking a few hours.

Our verdict: There is no downside to buying a hydrogen-ready boiler since the price premium is negligible and performance on natural gas is identical. However, do not buy one expecting hydrogen to arrive soon. The UK has no residential hydrogen heating network, and the government decision on whether to pursue hydrogen for homes was still pending as of early 2026. Most industry analysts believe hydrogen will be used for industrial processes rather than home heating.
Should You Buy a Gas Boiler in 2026?
Yes, buy a gas boiler if...
- Your boiler has broken down and you need heat now
- Your home is poorly insulated (EPC D or below)
- You have standard-size radiators and no budget to upgrade
- You live in a terraced house or flat with no outdoor space
- You plan to move within 5-10 years
- Your budget is under £4,000
Consider a heat pump if...
- You are doing a major renovation with insulation upgrades
- Your home already has underfloor heating or large radiators
- Your EPC is C or above
- You have space for an outdoor unit
- You plan to stay for 15+ years
- You want to use the £7,500 BUS grant
The bottom line: Gas boilers will be supported, serviced, and supplied for decades to come. A gas boiler bought in 2026 will last 12-15 years, by which point heat pump technology and energy prices may have shifted further in heat pumps' favour. There is no urgency to switch unless your home and circumstances make it financially sensible today.
Will a Gas Boiler Affect Your Home's Value?
In 2026, there is no evidence that having a gas boiler reduces your property value. What matters more is your EPC rating. A new, efficient gas boiler will improve your EPC (often by one or two bands), which can increase your home's value.
In the longer term (2030s onwards), homes with heat pumps may command a small premium as energy efficiency becomes a bigger factor in buying decisions. But for now, buyers care far more about having a reliable, modern heating system than about what fuel it uses.
Frequently Asked Questions
Will I be forced to remove my gas boiler?
No. The government has no plans to force existing homeowners to remove gas boilers. The 2035 ban applies to new-build homes only. You can continue to use, repair, and replace your gas boiler for the foreseeable future.
Are hydrogen boilers worth buying?
A hydrogen-ready boiler costs the same as a standard model (£0-200 premium) and performs identically on natural gas. There is no downside to buying one. However, do not rely on hydrogen arriving for home heating anytime soon. No UK residential hydrogen network exists, and the policy direction remains uncertain.
Will gas boilers be banned in existing homes?
Not under any current legislation. The 2035 ban targets new-build homes. The government's approach for existing homes is to incentivise switching through grants (like the £7,500 BUS grant) rather than mandating it. With 23 million gas-heated homes in England, a forced switchover is not practical.
Should I switch to a heat pump now or wait?
If your boiler is working and your home is not well insulated, wait. Use the time to improve insulation, which benefits any heating system. If you are doing a major renovation and your home suits a heat pump (good insulation, space for outdoor unit), the £7,500 BUS grant makes now a reasonable time to switch.
