The Energy Company Obligation (ECO4) is a government energy-efficiency scheme in Great Britain, designed to tackle fuel poverty and help reduce carbon emissions. ECO is an obligation placed on energy companies to deliver energy efficiency measures to domestic premises. ECO is not a grant scheme; it is up to the energy companies to determine which retrofit projects they choose to fund, the level of funding they provide, and the Retrofit Coordinator and installers that they choose to work with. Any obligated supplier can deliver measures to any domestic premises in England, Wales and Scotland, provided the eligibility criteria are met.
ECO4 measures were able to be delivered from the 1 April 2022. The ECO4 scheme will run until 31 March 2026.
ECO4 focusses on improving the least energy efficient homes and households in fuel poverty, as only properties in bands D-G can be treated. It also aims to deliver a more complete upgrade of those homes, shifting to a multi-measure whole-house retrofit approach. Furthermore, a minimum number of private tenure homes in energy efficiency rating band E, F and G must be upgraded throughout ECO4, ensuring the least efficient homes are treated.
It primarily focuses on providing funding for energy-efficient home improvements to low-income households and those living in poorly insulated homes.
You can get better heating, loft and cavity wall insulation, smart heating controls, solar panels, or even an air source heat pump among other measures with UK Energy Support – all 100% free, funded by the ECO4 Scheme.
Are You Eligible for ECO4 Scheme?
- Homeowners: The ECO4 Scheme is aimed at homeowners. Tenants can apply with landlord’s permission if they qualify. Landlords can encourage their tenants to apply (both parties need to agree).
- Income and Benefits: If your household has low income, and you receive qualifying benefits, you are likely to get it (no benefits? we may be able to help through other grants).
- Property Type and Condition: Prioritisation is given to households living in fuel poverty or with low Energy Performance Certificate EPC rating D and lower.

The Heating measures include:
- Solar Panels
- Air Source Heat Pumps
- Electric Storage Heaters
- First Time Central Heating
- Boilers (Non-condensing gas boiler to condensing boiler upgrade, like for like swaps)
.
Ensure that, as part of the installation, you also look at the hot water cylinder side when using solar and heat pump technologies. Our range of heat pump cylinders and solar compatible cylinders are supplied in a standard design, or bespoke designed to suit the available space.
Speak to our team today for further information on the cylinders.
