Can You Get a Heat Pump Grant If You Have Gas Central Heating?

Yes — and gas boiler replacement is exactly what the BUS grant was designed for. The Boiler Upgrade Scheme specifically targets homes switching from fossil fuel heating to heat pumps. If you have gas central heating, you tick one of the key eligibility boxes automatically.

Eligibility for Homes with Gas Central Heating

Replacing a gas boiler with a heat pump meets the BUS requirement to switch from fossil fuel heating. You also need to own the property, be in England or Wales, have a valid EPC, and use an MCS-certified installer. Your installer handles the application.

What Changes When You Switch from Gas

• Your gas boiler is removed
• An air source heat pump unit is installed outside
• A hot water cylinder is usually added (replacing the combi boiler function)
• Some radiators may need upgrading
• The gas supply can be disconnected (saving the standing charge)

Cost Comparison: Gas vs Heat Pump

Indicative figures for a typical 3-bed semi. Actual costs depend on insulation, tariff, and usage. Solar panels can cut heat pump electricity costs by 30-50%.

Do You Need New Radiators?

Not always. Many existing radiators work with heat pumps, though some may need upsizing because heat pumps operate at lower flow temperatures than gas boilers. Your installer will assess this during their survey. Read our full radiator guide for details. See also our full heat pump vs gas boiler comparison.
