Heat pump running cost

Estimates the annual electricity cost of running an air source heat pump for heating and hot water, using the maximum a supplier may lawfully charge per unit under Ofgem's domestic price cap. It is not a price, a bill, or an estimate of what you will actually pay — what you pay depends on your own tariff, supplier, and how efficiently your system actually runs.
