Current UK Home Energy Grants
ECO4 (Energy Company Obligation)
What it is: A government-backed scheme (running to March 2026) requiring major energy suppliers to fund energy efficiency improvements for lower-income and vulnerable households.
Typical measures: Loft, cavity and solid wall insulation, room-in-roof insulation, heating controls, first-time central heating, eligible low-carbon heating (e.g., heat pumps) and, in some cases, solar PV where suitable. A fabric-first approach applies.
Who it helps: Primarily owner-occupiers and private renters with EPC D–G. Qualifying benefits or local authority flexible eligibility can apply. Availability for social housing is limited by scheme rules and property rating.
What you pay: Many installs are fully funded; some homes may require a small contribution depending on the works and property.
Great British Insulation Scheme (GBIS)
What it is: A nationwide programme (to March 2026) focused on delivering a single, cost-effective insulation measure to reduce heat loss.
Typical measures: Loft insulation, cavity wall insulation, underfloor insulation, room-in-roof insulation and, in certain cases, solid wall insulation.
Who it helps: Two routes: the General Group (homes with qualifying EPC and council tax bands) and the Low-Income Group (benefit recipients or those eligible via LA Flex). Not everyone will receive a 100% grant; a contribution may be required, especially under the General Group.
Boiler Upgrade Scheme (BUS) – England and Wales
What it is: Upfront grants to help replace fossil fuel heating with low-carbon systems, available through to 2028.
Grant values: Typically up to £7,500 for air-source and ground-source heat pumps. Biomass boiler grants (usually £5,000) are available in limited circumstances (e.g., off-gas and outside certain air quality zones). Final amounts depend on scheme rules at the time of application.
Key requirements: An eligible EPC and no outstanding loft or cavity wall insulation recommendations (or these must be installed). Installations must be carried out by MCS-certified installers. Landlords can apply.
Home Upgrade Grant (HUG2) – Local Authority-led
What it is: Council-run funding for low-income, off-gas homes with lower EPC ratings. Timing and availability vary by local authority.
Typical measures: Insulation, efficient electric heating, air source heat pumps and renewables (subject to scheme design). Check your council’s current programme for dates and eligibility.
Local Authority Flexible Eligibility (LA Flex)
Under ECO4 and related programmes, councils can publish a Statement of Intent allowing them to refer households that are at risk of fuel poverty or have health vulnerabilities, even if they do not receive benefits. Criteria vary by council and may include income thresholds, health conditions and property EPC.
Other support in devolved nations
Scotland: Programmes such as Warmer Homes Scotland are delivered via Home Energy Scotland. Wales: The Nest scheme offers advice and support. Northern Ireland: Separate schemes operate via the Northern Ireland Sustainable Energy Programme. Availability and measures differ; we can signpost you to the correct service.
