What income counts for LA Flex?

Typically under £31,000 gross household income, but each council sets its own LA Flex criteria.

Do I need a recent EPC?

An old EPC may under-rate your home; a new assessment could qualify you. EPCs are valid 10 years.

ECO4 Eligibility (2026)

Before you apply for ECO4, check you qualify. This guide breaks down the two routes — benefits and LA Flex — plus the EPC rules, so you don't waste time or fall for a scam.

Last reviewed: August 2026

Benefits route

You most likely qualify if you or someone in the household gets Universal Credit, Pension Credit, Income Support, income-based JSA/ESA, Housing Benefit, or Child Benefit (income thresholds apply).

LA Flex route

If you don't get those benefits, your council can refer you via LA Flex if household income is typically under £31,000, or you're vulnerable to fuel poverty. Criteria vary by council.

EPC band rule

ECO4 targets the least efficient homes: bands E, F, G are highest priority; D qualifies if measures can reach band C; A–C usually don't qualify. Check your EPC on the government register.
