What is the Great British Insulation Scheme?

The Great British Insulation Scheme (GBIS) is designed to be complementary to the current ECO scheme, which is known as ECO4. The scheme will help install energy efficient measures that will lower your energy usage and save you money on bills. The scheme launched in Summer 2023 and will run until March 2026. The government believe the scheme will save households around £310 a year.(1)

How will the Great British Insulation Scheme help lower my bills?

Making our homes more energy efficient is the best way of cutting household energy use and reducing heating bills.

Insulation measures are included in this scheme and will help reduce heat loss and save money on your heating costs. This is because insulation keeps heat from escaping through your loft, windows and walls.

Who's eligible for the Great British Insulation Scheme?

Under the new Great British Insulation Scheme there will be two groups with different eligibility criteria, the general group and the low-income eligibility group. These groups will receive different levels of support. 

To be eligible for the general group, you must:

  • live in a home that falls within Council Tax bands A-D in England,
  • live in a home that falls within Council Tax band A-E in Scotland or Wales
  • have an EPC rating of D or below

If you're eligible, you may receive a single insulation measure. This group does not include the private renter sector.

To be eligible for the low-income eligibility group you must:

  • receive means-tested benefits
  • have an EPC rating of D or below

If you're eligible, you may receive a single insulation measure.

Properties with EPC ratings of F and G in the private rented sector will not be eligible for insulation measures. However, properties with EPC ratings of D and E can receive insulation measures, but heating control measures will not be installed.

Cavity wall insulation

Cavity wall insulation is one of the best and most affordable ways to improve your home's energy efficiency.

Insulating the cavity space between the outside and inside wall adds a barrier to stop the cold from coming in and heat from escaping.

No, we're offering our Great British Insulation Scheme to anyone not just EDF customers.

We are unable to accept applications from social housing tenants. Please contact your social housing provider to discuss the options they have available. If they do provide permission for you to approach an installer directly, you can find a government-endorsed installer by visiting the industry quality assessor, Trustmark.

For customers who privately rent funding may be available provided the tenants meet certain criteria, such as earning a low income and living in a property with an EPC rating that's D or below.

EDF works with a network of fully accredited installers who will assess your property to determine if an installation is needed.

We aim to install single low-cost insulation measures to households rather than multi measures. Alternative types of insulation are more costly and can take longer to install.

Even if you don't qualify for either group's eligibility criteria, you can still opt to pay for insulation. We're here to assist you in arranging to install cavity wall insulation in your home.
