1 Geographical and eligibility restrictions apply. A 2023 study indicates that air heat pumps are up to four times more efficient than average gas boilers over a full year, as measured by the Seasonal Coefficient of Performance (SCOP). This metric includes all heating and hot water, providing a realistic comparison to combi boilers.

2 Figures are based on standard MCS calculations for a south-facing 12-panel solar array in central England, on a 35-degree tilt roof, with no shading, and annual electricity usage of 4,800 kWh. The tariff rate is 22.4p/kWh (Ofgem Energy Price Cap from 1 July 2024). Savings assume a 5.1 kWh battery and Smart Export Guarantee (SEG) payments of 40.0p/kWh under the E.ON Next Export Exclusive tariff. Actual savings may vary.

6 Savings information for heat pumps provided by the Energy Saving Trust based on a standard air source heat pump in an average sized, four-bedroom detached home, with radiator upgrades as required versus an old G-rated gas boiler.

7 These are example figures only, based on standardised MCS calculations. Savings are based on property fitted with a south-facing solar array in central England on a roof with a 35-degree tilt and no shading, with electricity consumption of 4,800 kWh per year (with the customer Home all day), at a tariff rate of 22.4p/kWh. The solar array contains 12 x 435W panels (5.22 kWp) generating 4,881 kWh/year, fitted with a 5.1 kWh (5.1 kWh usable) battery.
