Frequently Asked Questions
❓ What is the ECO4 scheme?

❓ How does the ECO4 scheme work?
Energy companies are legally obligated to meet carbon-saving targets by funding home improvements. They partner with approved installers who assess your home, recommend suitable measures (like A-rated boilers), and complete professional installations at zero cost to eligible households.
❓ Who is eligible for ECO4 and GBIS?
You may qualify if you receive benefits (Universal Credit, Pension Credit, Child Tax Credit, etc.), have a low household income (LA Flex route), or your property has an EPC rating of D-G. Homeowners and private tenants (with landlord permission) can apply.
