GBIS Explained: What Is the Great British Insulation Scheme?

If your home is hard to heat or your energy bills are too high, the Great British Insulation Scheme (GBIS) could offer the help you need. Launched by the UK government, GBIS aims to make homes across the country warmer, cheaper to run, and better for the environment.

In this guide, we’ll explain how the scheme works, who’s eligible, what’s included, and how to apply.

What Is the Great British Insulation Scheme?

The Great British Insulation Scheme is a government-funded programme that provides free or low-cost insulation upgrades to households across Great Britain. It was introduced in 2023 as part of the UK’s broader plan to cut energy use and reduce carbon emissions.

Previously known as “ECO+”, GBIS is focused on single, high-impact insulation measures, especially for homes with poor energy performance ratings.

The scheme is expected to run until March 2026.

What Types of Insulation Are Included?

Depending on your home and needs, you could receive one of the following upgrades through GBIS:

  • Loft insulation
  • Cavity wall insulation
  • Solid wall insulation (internal or external)
  • Underfloor insulation
  • Flat roof insulation
  • Room-in-roof insulation

These improvements can significantly reduce the amount of heat lost from your home, helping you stay warm and save money.

Who Is Eligible for GBIS?

GBIS has two main eligibility routes: the low-income group and the general group.

Low-Income Group

You may qualify if you:

  • Receive means-tested benefits such as:
    • Universal Credit
    • Child Tax Credit
    • Income Support
    • Pension Credit
  • Live in a property with an EPC rating of D or lower

General Group

If you're not receiving benefits, you might still qualify if you:

  • Live in a home with an EPC rating of D–G
  • Are in a Council Tax band A–D (England), A–E in Wales and Scotland

Landlords and tenants may also be eligible under certain conditions, as long as the tenant consents to the work.

How Much Could You Save?

Insulation is one of the most cost-effective ways to cut energy use. Here’s what you could save each year with a typical installation:

Insulation Type Estimated Annual Savings*
Loft insulation £300+
Cavity wall insulation £400+
Solid wall insulation £500–£900
Underfloor insulation £150–£250

*Figures based on 2025 energy prices and average UK homes. Actual savings will vary depending on your home and energy use.
