How does the ECO scheme work?

You may already know you can reduce your energy bills with loft and cavity wall insulation. What you might not know is that with the government's ECO scheme, you may not have to pay for insulation at all. This government scheme is designed to help people in the UK reduce energy loss in their homes and lower heating costs.

Common questions asked:

Am I eligible for the ECO scheme?

  1. You don't have to be an EDF Energy customer to qualify for free loft or cavity wall insulation
  2. You must either own (and live in) your home or be a private tenant(2)
  3. Your home must be considered suitable for loft or cavity wall insulation if you’d like these improvements(3) 

How do I apply?

The first thing to do is call us on 0800 404 6068. We’ll run through the eligibility criteria (above) to check you qualify. If you qualify, we’ll set up a free, no obligation home assessment with one of our qualified installers. They’ll visit to check your house is suitable. It'll be around four weeks after you first get in touch with us.

What happens at the assessment?

The installation company will take some measurements and photos. The assessment will take around two to three hours, depending on the type of property you live in. You might need to show them some paperwork (like a tenancy agreement or proof of benefits). They’ll also need to do a technical survey – they’ll either do this on the same day as the assessment, or make an appointment with you to come back another day.

The installer will then tell you which improvements will be best for you subject to technical survey. There might be some extra costs you need to pay but they’ll let you know what these are before they start the work.

How long do the improvements take to get installed?

As long as you’re happy to go ahead, the installer will book a date for the work – usually around four to five weeks after your technical survey. You’ll need to sign a contract with them for this.

Once the work’s finished, they’ll send your warranty and maintenance documents in the next two to three weeks.
