Through ECO4 Flex, a local authority (LA) can nominate privately owned households facing fuel poverty or low income and vulnerable to the challenges of residing in a cold dwelling. Eligibility criteria depend on your local authority, so it's important to check with your council to see if you're eligible.

Typically, ECO4 Flex targets areas where there are more off-grid properties or those without a mains gas supply. In these areas, people are more likely to rely on less environmentally friendly and efficient heating methods, which results in higher energy costs. If you're experiencing fuel poverty or low income and live in one of these areas, ECO4 Flex could be a valuable resource for you.
