ECO4 (Energy Company Obligation)
ECO4 is the fourth iteration of the Energy Company Obligation scheme, running until 31 December 2026 after a nine-month extension. Large energy suppliers are obligated to fund energy efficiency measures in low-income and fuel-poor households. For landlords, this can mean funded improvements to rented homes rated E, F or G when the tenant is on qualifying benefits or the local authority declares them eligible.
Boiler Upgrade Scheme (BUS)
The Boiler Upgrade Scheme provides upfront capital grants to support the installation of low-carbon heating systems like heat pumps. It is open to owners in England and Wales, including landlords, and its regulations now run to 2030. Grants are £7,500 for air source and ground source heat pumps, £2,500 for air-to-air heat pumps and £5,000 for biomass boilers in rural off-gas properties. Until March 2027, an air source or ground source heat pump in a home heated by oil or LPG with no mains gas connection gets an extra £1,500 (£9,000 in total). There is no EPC rating or insulation condition.
Warm Homes: Local Grant
Delivered by local authorities in England since 1 April 2025, with the delivery window closing on 31 March 2028. It funds energy performance upgrades and low carbon heating in low-income households, including private rentals rated EPC D to G, with cost caps of £16,600 per home for each. One home per landlord can be fully funded, with a 50% landlord contribution for any additional homes. Rented homes rated F or G need a registered exemption to be eligible.
Great British Insulation Scheme (closed)
GBIS ended on 31 March 2026 and is closed to new installations, so it is no longer available. It focused specifically on insulation measures, targeting properties in Council Tax bands A-D with poor energy efficiency (EPC D or below). It was funded by energy suppliers and covered cavity wall, loft, and other insulation measures.
