The UK Government offers several schemes to help homeowners reduce the cost of upgrading their heating systems. These are designed to improve energy efficiency, reduce carbon emissions, and help households save on their energy bills.
Available Schemes (2026)
- ECO4 Scheme: The Energy Company Obligation scheme provides free or heavily subsidised boiler replacements for eligible low-income households. If you receive certain benefits, you may qualify for a free new boiler.
- Boiler Upgrade Scheme (BUS): Government grants to help homeowners switch from fossil fuel heating to low-carbon alternatives like heat pumps. Grants of up to £7,500 available.
- Great British Insulation Scheme: Funding for home insulation improvements that can significantly reduce your heating costs and improve boiler efficiency.
How to Save on Your Heating Bills
Beyond government grants, there are several ways to reduce your heating costs:
- Upgrade to an A-rated boiler: Modern condensing boilers are up to 94% efficient, compared to 60-70% for older models — saving up to £300/year
- Install a smart thermostat: Programmable controls let you heat your home only when needed, saving up to 20% on heating bills
- Improve insulation: Loft and cavity wall insulation reduces heat loss, meaning your boiler works less hard
- Annual boiler service: Regular servicing keeps your boiler running at peak efficiency and prevents costly breakdowns
- Radiator balancing: Properly balanced radiators ensure even heating throughout your home without wasting energy
Boiler Grants FAQ
Am I eligible for a free boiler grant?
You may be eligible for a free boiler under the ECO4 scheme if you receive certain benefits (Universal Credit, Pension Credit, Child Tax Credit, etc.) and your current boiler is inefficient. Contact us for a free eligibility check — we'll help you understand your options.
How much can I save with a new boiler?
Replacing an old G-rated boiler with a new A-rated condensing boiler can save you up to £300 per year on your heating bills. Combined with a smart thermostat and proper insulation, total savings can exceed £500/year.
What is the Boiler Upgrade Scheme?
The Boiler Upgrade Scheme (BUS) provides grants of up to £7,500 towards the cost of replacing fossil fuel heating with a low-carbon heat pump. While this isn't a direct boiler grant, it's worth considering if you're looking at long-term heating solutions.
