Unfortunately, there are no funding options available to replace your boiler. However, you could look into renewables. With the government pushing for more renewable energy sources to be fitted in homes, there is a £7,500 grant under the Boiler Upgrade Scheme to support the upgrade to an Air Source Heat Pump.
Air Source Heat Pumps offer up to 400% efficiency, and they future-proof your home against gas prices. You can use your boiler upgrade grant to replace a heating system in your home, a second home, a property you rent out to tenants or a building you use for your business.

The Boiler Upgrade Scheme (BUS) is currently the best immediate option for homeowners looking to switch to greener energy. It provides a £7,500 grant specifically for Air Source Heat Pumps, which can bring the installation cost in line with a standard gas boiler.
Air Source Heat Pumps (ASHPs) offer up to 400% efficiency and help future-proof your home against rising gas prices. While a like-for-like gas boiler replacement is often the most cost-effective initial option , ASHPs are a superior low-carbon alternative for reducing your carbon footprint.
