ECO4 is the 4th and latest incarnation of The Energy Company Obligation (ECO) which has been running since 2013 and is an official UK government-backed scheme where qualifying homeowners & private tenants on certain means-tested benefits could have their inefficient heating systems replaced completely free of charge. Unlike previous versions of the scheme, the ECO 4 grant is to be targeted to ensure the least energy-efficient homes are brought up to a minimum efficiency standard. From January 2023, the scheme is focussed on upgrading properties with EPC ratings of E-G and improving these to a minimum rating of D as outlined in the ECO4 mission statement. The great news is that for properties that meet certain criteria, the grants available are much improved and we have overseen projects where individual homes have qualified for total upgrades of £30,000+ with savings of up to 70% on annual energy bills!
