Frequently asked questions
Here are some of the most common questions we receive about the ECO4 scheme, the Great British Insulation Scheme and how we can help.
The ECO4 scheme is a government-backed initiative that helps low-income and vulnerable households access free or subsidised energy efficiency upgrades, such as insulation, first-time central heating and renewable heating systems. If you qualify, the work is fully funded by energy suppliers and carried out by accredited installers.
This scheme is designed to help more households across the UK install insulation at little or no cost. It is open to a wider range of properties than ECO4 and aims to improve energy efficiency, lower energy bills and reduce heat loss by installing measures like loft, cavity wall or solid wall insulation.
Eligibility depends on a few factors, including your income, whether you receive certain benefits, the energy rating of your home and your current heating system. You can use our quick online checker to find out if you qualify for either scheme.
In many cases, the upgrades are completely free, especially under the ECO4 scheme if you meet the criteria. Under the Great British Insulation Scheme, you might be asked to contribute a small amount, but many households still receive support at no cost.
