Find out if you qualify for government-funded insulation through the ECO4 scheme, and what's changing in 2026.
The Energy Company Obligation (ECO4) is the current government scheme funding free insulation for eligible households. To qualify, you typically need to meet criteria based on benefits received or household income.
Even if you don't receive the benefits listed above, you may still qualify through ECO4 Flex, which allows local authorities to refer households based on other vulnerability criteria.
Households with a combined income below £31,000 living in properties with an EPC rating of D-G may qualify, even without receiving means-tested benefits.
People with health conditions made worse by living in a cold home, such as cardiovascular, respiratory, or mobility issues, may be eligible.
Households with children under 5, people over 65, or those receiving certain disability benefits may qualify through local authority referral.

The government has announced significant changes to home energy efficiency funding. Here's what you need to know.
The current ECO4 scheme is confirmed to end on 31 March 2026. The government announced in the Autumn 2024 Budget that ECO will not be renewed in its current form, with costs being moved off energy bills and into general taxation.

The Warm Homes Plan will be delivered through local authorities and combined authorities, with funding allocated through schemes like the Warm Homes: Local Grant and Warm Homes: Social Housing Fund.
ECO4 ends 31 March 2026. Apply now to secure funding under the current scheme.
