What is the Great British Insulation Scheme?

The Great British Insulation Scheme (GBIS) helps eligible UK households improve energy efficiency with free or discounted insulation.* Upgrading your home insulation can provide multiple benefits, including consistent indoor temperatures, improved comfort, and reduced energy bills.

What insulation types does the GBIS cover?

How can the Great British Insulation Scheme help you save?

Did you know that over half of the average UK household’s energy bill goes toward heating and hot water? Without proper insulation, a significant portion of that heat escapes through walls, roofs, and windows — with around 33% lost through uninsulated walls alone.

By improving your home insulation through the Great British Insulation Scheme (GBIS), you can reduce heat loss, lower your energy bills, and keep your home warmer in winter and cooler in summer. Insulation works like a protective barrier, helping your boiler run more efficiently and cutting energy costs while enhancing

The Great British Insulation Scheme (GBIS) is available to homeowners, landlords, and private tenants across the UK. To qualify, your home must typically have an EPC rating of D or lower, and meet one of the following criteria:

  • Your property falls within Council Tax Bands A to D in England, or A to E in Scotland and Wales.

  • Someone living in the property receives a qualifying benefit.

Even if you’re unsure, it’s worth checking your eligibility — many households qualify for free or discounted insulation under GBIS funding.

Your Council Tax Band determines how much local tax you pay and also helps identify your eligibility for GBIS funding.
To qualify for the scheme, your property must be in:

  • Bands A–D in England, or

  • Bands A–E in Scotland or Wales.

You can check your Council Tax Band online by visiting the official GOV.UK Council Tax Band Checker.

An Energy Performance Certificate (EPC) shows how energy-efficient your home is, rated from A (most efficient) to G (least efficient).
To be eligible for the Great British Insulation Scheme, your property usually needs an EPC rating of D, E, F, or G.

You can check your EPC rating for free on the official GOV.UK EPC Register.

No — you don’t need to be an E.ON Next customer to benefit from the Great British Insulation Scheme. The initiative is government-backed and available to all eligible households in the UK, regardless of energy supplier.

The GBIS covers a range of insulation measures designed to reduce heat loss and improve home comfort. Depending on your property, you could qualify for one or more of the following:

  • Cavity Wall Insulation

  • Loft Insulation

  • Room in Roof Insulation

  • Solid Wall Insulation (Internal or External)

  • Underfloor Insulation

These upgrades can help reduce energy waste, lower heating bills, and improve your home’s EPC rating.

Your insulation type will depend on your property’s construction, location, and existing insulation levels. A qualified energy assessor will carry out a home survey to determine the most suitable insulation measure.
While you can express a preference, the final recommendation will be based on GBIS criteria to maximise your home’s energy efficiency and savings.

Both ECO4 and GBIS are UK Government energy efficiency schemes, but they serve different purposes:

  • ECO4 Scheme – Focuses on whole-home energy efficiency upgrades for low-income and vulnerable households, covering heating systems, insulation, and renewable technologies.

  • GBIS Scheme – Aims to provide single insulation measures, such as loft or wall insulation, to a broader range of households, including middle-income families.

In simple terms, ECO4 targets deep retrofits, while GBIS offers affordable insulation improvements to help more homes reduce energy bills.

Under the GBIS Child Benefit eligibility criteria, your income must fall below a certain threshold depending on your household size:
