The scheme covers energy-saving upgrades including free boiler replacement, central heating systems, loft or wall insulation, renewable heating solutions, and smart controls — depending on your property’s needs and eligibility.
Yes, if you meet the eligibility criteria, your upgrades are 100% funded through the government’s ECO 4 program. You won’t pay anything for the installation or equipment — the funding comes from major UK energy companies.
