According to the Energy Saving Trust (January 2024), a detached household moving from a G-rated boiler to a new A-rated condensing boiler with a programmer, room thermostat and thermostatic radiator controls (TRVs) could save up to £580 a year. Savings will vary depending on the size and thermal performance of your home.
Actual sum is £399.71. Savings of £399 are based on the following comparison: a G-rated gas boiler running at 70% efficiency with an average annual consumption of 10,436 kWh at 6.33p per kWh used for heating and hot water, versus an air source heat pump with a Seasonal Coefficient of Performance (or efficiency rating) of 4.2 and an annual consumption of 1826 kWh at 15p/kWh with the Heat Pump Plus add-on.
