From time to time there are Government incentives to encourage householders to generate renewable energy and to make their homes more energy efficient. The most recent of these (from April 2022) is the Boiler Upgrade Scheme (BUS). This grant provides £5,000 off the cost of an air source heat pump or a biomass boiler and £6,000 off the cost of a ground source heat pump.
To encourage householders to make their homes more energy efficient the Government set up the Energy Company Obligation which for people on low incomes means that certain energy improvements can be carried out at no cost to them.
