What is the ECO4 scheme?

The Energy Company Obligation (ECO) scheme is a government scheme which takes a whole house, insulation first approach to reduce fuel poverty across England, Wales and Scotland. After insulation has been completed, any further savings that can be made by upgrading heating can also be completed through the scheme.

The scheme is funded by the largest utility companies in the UK and we work with them to provide access to this free funding, helping to reduce your fuel bills, making your home warmer and reducing condensation, damp and mould which is associated with poorly insulated and heated homes.

Not every household can apply and there are certain criteria which have to be met in order to qualify for the scheme. The ECO grants are not repayable and for most installs will cover the whole cost of the installation.
