If you came here looking for an ECO4 grant, here’s where things stand: ECO4 runs until 31 December 2026, and Consumer Rights can no longer help with ECO4 applications. This page explains what that means, what to do if you already have ECO4 work under way, and where to look for help instead.

Is ECO4 ending?

ECO4 is the fourth phase of the Energy Company Obligation, which requires larger energy suppliers to fund energy-efficiency improvements for lower-income and vulnerable households. Ofgem says ECO4 “will run until 31 December 2026, following a nine-month extension”. No ECO5 has been announced.

Ofgem also says ECO “is not a grant scheme”. Energy suppliers decide what they fund, a household may be asked to contribute, and being eligible doesn’t guarantee an installation.

The related Great British Insulation Scheme (GBIS) ended on 31 March 2026 and is now closed to new installations.

What can I look at instead?

The government’s current home energy schemes sit under its Warm Homes Plan. Your options include:

See all of them side by side on our home energy grants overview, or browse the grants and funding hub.

I already have ECO4 work under way — what now?

Contact the installer who arranged the work to confirm the timeline, bearing in mind ECO4 ends on 31 December 2026. Keep written records of what you’ve been told. If something has gone wrong with work that has already been done, complain to the installer first and then to the energy supplier that funded the work — our guide to ECO4 complaints explains the steps.

Watch out for ECO4 scams

As ECO4 nears its end date, be extra wary of anyone cold-calling, texting or messaging you about “free ECO4 grants”. Never pay an up-front fee to someone who approaches you unsolicited, and check any installer on the TrustMark register. If in doubt, read our guide to spotting ECO scams.

For reference: how ECO4 works

ECO4 applies to measures installed from 1 April 2022. Households can be covered through qualifying benefits or through ECO4 Flex (LA Flex), which lets councils and the Scottish and Welsh governments refer low-income or vulnerable households who aren’t on qualifying benefits. ECO4 Flex ends with ECO4. Our ECO4 guides stay online for reference.
