Local Authority Flexible Eligibility (LA Flex), is part of the ECO scheme, and gives local authorities scope to widen the eligibility criteria for the ECO scheme so that more households will be able to benefit from solar grants. The ‘flex’ aspect of the scheme means that local authorities are able to have greater flexibility to tailor qualifying requirements specific to their respective areas and the needs of the people living in that area. This means more residents, not just those claiming benefits, can qualify for solar grants and other types of eco funding. Being based on factors like low income, health, age, or location, means that councils are able to better target grants at people who most need it, either because they are living in fuel poverty (i.e. spending at least 10% of their net income on heating their home) or at significant risk of living in a cold home during winter (including those with cardiovascular or respiratory conditions, disabilities, mental health conditions and learning disabilities, aged 65+, with young children under 5, or pregnant.) Households that have a property with EPC rating of E, F or G who meet any two of the following criteria could also be eligible for a solar grant under LA Flex: House is in the low-layer super output (LSOA) 1–3 area (considered the most deprived in England. Householder receives a Council Tax rebate due to low income. Someone in the household is vulnerable to living in a cold home Householder has been referred by the Local Authority Delivery (LAD) scheme. Some households receive free school meals. Household struggles with sustained debt on mortgage and utility bills, and has been advised to seek support by a recognised agency (mortgage lender, energy supplier or Citizens Advice)   LA Flex has been expanded under ECO4 so that energy suppliers will be able to provide up to 50% of their obligation via LA Flex, as opposed to the 25% it was previously under ECO3. To achieve funding under LA Flex, the local authority need to send a signed declaration to the relevant energy company confirming eligibility on behalf of the customer. This declaration will be presented to accredited ECO installers for the grant to be awarded.
