What is ECO?

ECO is a grant funded scheme available for eligible homeowners to install property improvements to a home’s insulation and heating, as required, to increase overall energy efficiency.

The government grant is designed to improve the thermal comfort of an eligible homeowner’s property by installing insulation such as:
