With the possibility of financial support from the government’s Green Homes Grant (only available in England) and the Renewable Heat Incentive (RHI), the prospect of switching a gas- or oil-fired boiler for an air-source heat pump (ASHP) seems more enticing than ever before. Powered by electricity, ASHPs extract warmth from the air, and increase the temperature to supply heating and hot water. But how much does air source heat pump cost? The average cost of an ASHP for a three-bedroom detached house is between £8,000 and £10,000,’ says Max Halliwell, heat pump specialist at Mitsubishi Electric. It is possible this outlay can be offset against financial incentives provided by the RHI and, if you live in England, the Green Homes Grant – as long as you meet the necessary criteria. ‘The latter scheme, for instance, provides homeowners with vouchers covering two thirds of the cost of eligible improvements, up to a maximum of £5,000,’ Max adds.
