FAQ

ECO4 is a government energy efficiency scheme running from 1 April 2022 to 31 March 2026. Its main goal is to upgrade the least energy-efficient homes—especially those lived in by low-income and vulnerable households—to help cut energy bills and reduce carbon emissions.

Funding for ECO4 comes directly from medium and larger energy suppliers in Britain. Each supplier has a target based on its share of the domestic energy market. To meet these targets, they work with approved installers to provide and fit energy efficiency measures in households.

To qualify, you’ll first need to check your eligibility. Simply complete our quick eligibility checker to find out if your home meets the requirements. If you qualify, we’ll handle the rest of the process for you—making it simple and hassle-free.

Yes. ECO4 is the latest phase of the UK Government’s ongoing energy efficiency initiative. It is designed to support lower-income households, particularly those facing fuel poverty, by improving home energy efficiency and reducing bills.

Upgrading to an A+ rated condensing boiler could cut your energy bills by 20–30%. It also helps protect you from the impact of future energy price increases while reducing your household’s carbon footprint.

The official information on the Energy Company Obligation (ECO4) scheme, which runs until March 31, 2026, is provided by Ofgem, the UK’s energy regulator, on behalf of the government. For homeowners and tenants, the primary resource is the FAQs for domestic consumers and landlords page on the Ofgem website. This covers common questions about eligibility, funded measures (like insulation, boilers, and heating upgrades), how the scheme works, and application steps.

Key highlights from official sources:

• Eligibility: You may qualify if you’re on certain benefits, have low income (under £31,000 combined household), or live in a low-energy-efficiency home (EPC rating D-G). Local authorities can refer via ECO4 Flex for broader access.
