The first step is to get in touch with us on 0333 200 5119(1).

1 Consultation

Answer our quick questions to find out whether you’re eligible for the ECO scheme. For a gas boiler replacement, you’ll need to tell us the current model of your boiler. 

2 Book a date

We’ll arrange your technical survey with our installer who’ll be able to confirm what options you qualify for. Technical survey appointments are often booked within four weeks of your initial call.

3 Home visit

Our installer will gather all the information we need to assess your property. They’ll let you know any technical requirements needed for the improvements.

After the technical survey has been completed, we’ll get to work on the improvements. Our installer will send you an invoice if there’s any additional work needed before the installation begins. We aim to have all measures installed within three months of your initial contact.

Can I spread the cost of installation via finance?

Unfortunately, EDF Energy doesn't offer a finance option. 

Can I apply for the ECO scheme online?

Not at the moment, but we hope to have this functionality in the future, for now you can enquire through your account, or switch to EDF Energy.


If I’m not eligible for the ECO scheme, can I pay for insulation and/or a replacement boiler to be installed?

Yes, EDF Energy has a replacement boiler offer and many more energy efficiency options.


Why are council/social housing tenants not eligible for the ECO scheme?

Your local council is responsible for maintaining its housing. Please contact them to see if any help is available.

Who do I contact if I have a query or complaint about my installation?

In the first instance, you should contact the installer directly. If you are unsatisfied with their response, please contact the EDF Energy ECO team on 0333 200 5119.

Are there any property types that don’t qualify for the ECO scheme?

Certain property types may not be able to receive certain measures, such as insulation in park homes, or properties more than three storeys high.
