Will Gas Boilers Be Phased Out? Government Plans and Reality

Yes — new gas boiler installations will end by 2035. This is confirmed government policy backed by legally binding climate targets. The exact date might shift slightly, but the direction is irreversible. The smart move is to plan your transition now, while £7,500 grants are available and installers are not overwhelmed with demand.

It is one of the most searched heating questions in the UK. The short answer is yes — new gas boiler installations are set to end by 2035. But the reality is more nuanced than the headlines suggest. For the full comparison of alternatives, see our pillar guide.

What the Government Has Actually Said

• 2035: No new gas-only boilers installed in existing homes
• 2025 onwards: New-build homes must meet the Future Homes Standard (usually requiring heat pumps)
• Net zero by 2050: Legally binding under the Climate Change Act

These are not vague aspirations. The net zero target is law. The Future Homes Standard is regulation. Supporting mechanisms — the BUS grant, Clean Heat Market Mechanism — are already operating.

Why It Is Happening

Home heating accounts for roughly 15% of UK carbon emissions. The vast majority of 24 million homes are gas-heated. Decarbonising this sector is essential for net zero. The government has concluded that heat pumps are the primary replacement technology.

A Reality Check: Will It Actually Happen on Time?

Arguments it will: Net zero is legally binding. Multiple supporting mechanisms are already active. Heat pump technology is mature and proven. Installer capacity is growing rapidly.

Arguments for delay: Current installation rates are below target. Some property types are challenging. Political pressure from homeowners could lead to flexibility on timing.

Our assessment: The direction is certain — gas boilers will be phased out. The 2035 date may shift by 1-2 years in either direction, but the transition is happening. Waiting for it to be postponed is a gamble with poor odds.

What It Means for You

If your boiler is under 5 years old: You have time. Start researching and improving insulation. Get a survey when your boiler reaches 10 years old.

If your boiler is 10-15 years old: Start getting quotes now. Act when the boiler needs its next major repair or reaches end of life. The grant makes it much more affordable.

If your boiler has failed: Seriously consider a heat pump instead of another gas boiler. With the grant, costs are comparable, and you future-proof your home. Get quotes today.

Combining a heat pump with solar panels creates a fully renewable energy home and maximises savings from day one.

Frequently Asked Questions

Will gas boilers definitely be banned by 2035?

The 2035 target is confirmed policy backed by the legally binding net zero 2050 target. The exact date could shift slightly, but the direction is clear and irreversible.

What if the government changes its mind?

The net zero target is law under the Climate Change Act. The mechanisms (BUS grant, CHMM, Future Homes Standard) are already in operation.

Should I panic and replace my boiler now?

No panic needed. If your boiler is under 10 years old, you have time. But if it is ageing, getting quotes now secures grants and avoids future rush.

Will heat pump installation get cheaper?

Prices should decrease gradually as the market scales. However, grants may also reduce. The current combination of mature technology and £7,500 grants is a strong time to act.

What happens to gas prices?

Gas prices are expected to rise as carbon taxes increase and production declines. Green levies are being moved from electricity to gas bills, making gas more expensive relative to electricity.
