KAELTRIPTON VERDICT Air source heat pump fully installed: £8,000-£15,000. After £7,500 BUS grant: £500-£7,500. Well worth it if: your home is EPC C or better; you can switch to an off-peak electricity tariff; you have or plan underfloor heating or large radiators. Less compelling if: on standard electricity tariff; EPC D or below without planned insulation.
