   As of 2022 the installation cost of a heat pump is more than a gas boiler, but with the "Boiler Upgrade Scheme" [104] government grant and assuming electricity/gas costs remain similar their lifetime costs would be similar on average. [105] However lifetime cost relative to a gas boiler varies considerably depending on several factors, such as ...
