What we do
We explain the ECO4 scheme (the Energy Company Obligation) in plain English, using GOV.UK and Ofgem as our sources, and we show the date we last checked each fact. If you fill in the eligibility enquiry form, we read your answers and reply by email with the ECO4 route that may fit your home, or tell you if ECO4 is unlikely to help.
What we do not do
- We do not decide ECO4 eligibility. Energy suppliers and, for ECO4 Flex, local councils do that.
- We do not install anything, carry out surveys or employ installers.
- We do not have an installer partner, and we do not pass your details to an installer.
- We do not promise a grant value, an approval or a timescale.
Sending us the checker is no obligation and costs nothing. Before you agree to any ECO4 work, we always suggest you check the installer on the TrustMark register, as Ofgem requires ECO installers to be TrustMark accredited.
