Cost after grant
Based on current energy prices, a heat pump would cost more to run than your existing boiler.
Your boiler is already highly efficient, so the running cost saving isn't there at today's gas-to-electricity price ratio. However, heat pumps still reduce carbon emissions and protect against future gas price rises. A heat pump may become more cost-effective as electricity prices fall relative to gas.

What Homeowners Say About Our Heat Pumps
“From start to finish, Improveasy made the process simple. The grant was handled for us and the installation was quick and tidy.”
“Our home is warmer, quieter, and cheaper to run. We wish we’d done it sooner.”
How Does an Air Source Heat Pump Work?
Air source heat pumps extract heat from the outside air even in cold weather and convert it into energy to heat your home and hot water. They work most efficiently with low-temperature heating systems like radiators and underfloor heating.
They’re highly efficient, low-maintenance, and powered by electricity rather than gas.
