The ECO4 Flex Scheme is currently closed until further notice. Applications will not be accepted/processed at the current time.

New applications by ECO4 Flex providers/installers wishing to onboard with Ceredigion County Council’s ECO4 Flexible Eligibility Scheme are now closed. We are hoping to review this during the second phase of the scheme in April 2023.

ECO4 was launched in 2022 and will run until March 2026. The scheme will focus on supporting low income and vulnerable households and will improve the least energy efficient homes helping to meet the Government’s fuel poverty and net carbon zero commitments. Local authorities can volunteer to participate in ECO4 Flex to identify eligible households.

ECO4 Flex is regulated by Ofgem and the measures installed are funded by the energy companies. Ceredigion County Council have the responsibility of determining who will qualify for ECO4 Flex in the County. This will be established based on the information supplied in the application form together with the supporting evidence. Declarations will be issued to those who are eligible and could benefit from improvements. 

To qualify, properties must be an occupied private domestic premises (either owner-occupied homes or private rented sector households). Both the property and the household must adhere to at least one of the three available routes outlined below (Definitions: EPC = Energy Performance Certificate, SAP = Standard Assessment Procedure):

Route 1: Property EPC/SAP bands D-G (bands E, F or G for private rented sector households) and households with an income less than £31,000. This cap applies irrespective of the property size, composition, or region.

Route 2: Property EPC/SAP bands E-G and households that meet a combination of two proxies (please refer to the application form and accompanying letter for further information).

Route 3: Property EPC/SAP bands D-G (bands E, F or G for private rented sector households) and households that have been identified by their doctor or GP as low-income and vulnerable, with an occupant whose health conditions may be impacted further by living in a cold home. These health conditions may be cardiovascular, respiratory, immunosuppressed, or limited mobility related.

What if there is no current EPC for your property?

You can check whether there is a valid EPC on your property by visiting If there is currently no valid EPC for your property, then you can arrange for your property to be assessed by an accredited Domestic Energy Assessor (DEA), for which there is a charge (this can vary between DEAs). The DEA then carries out the energy assessment and issues an Energy Performance Certificate. You can find your nearest DEA on the UK Government website by visiting Alternatively, you can contact one of the Council’s approved ECO4 Flex installers from the list; in this case, please contact the Council’s Housing Services on 01545 572105.
