Usually under the ECO scheme residents who are either homeowners or private tenants are directed to contact one of the participating major energy suppliers. Eligibility is dependent on the receipt of certain benefits and stipulations concerning the existing property characteristics such as a maximum existing level of loft insulation and that heating systems must be broken or condemned to qualify or require a qualifying ‘dual measure’ such as cavity wall or underfloor insulation to access funding to upgrade older inefficient but working boilers. Please note that the offer available may differ between energy suppliers and you may need to be a customer with some providers.
