What is the Great British Insulation Scheme?

The Great British Insulation Scheme (GBIS) is a UK government initiative, aiming to improve energy efficiency in the worse insulated homes. It puts an obligation on energy suppliers to implement energy-saving measures in domestic properties, particularly focusing on insulation.

This scheme, a part of the broader Energy Company Obligation (ECO), and is instrumental in reducing carbon footprints and helping householders to reduce energy consumption in the home.

The scheme is administered by Ofgem and is due to run until 31 March 2026.

The person’s severe or long-term health condition must be due to:

• A cardiovascular condition,
• A respiratory disease,
• Limited mobility, or
• Immunosuppression.

GBIS Property Qualifying Criteria – EPC Rating/Council Tax Band Rating

The qualifying criteria for properties under GBIS are centered around Energy Performance Certificate (EPC) ratings and Council Tax band ratings.

Properties with lower EPC ratings (typically D to G) and those in specific Council Tax bands are prioritised, aligning with the scheme’s goal of improving energy efficiency in less efficient homes. 

What is an EPC? 

An Energy Performance Certificate typically called an EPC, shows the energy rating of a property from a G the lowest to an A the highest.

The ratings go from a scale of 1 to 100, these are called Sap points. These are then subdivided into bands, so for example 1 – 20 is a G rating, 21 – 38 is an F rating etc.

We can arrange to carry out an EPC for you to find out the rating of your property. An EPC typically costs £60 to £70. However, you can first check if you have an epc.

If you are worried about incurring any costs, you can always give us a call on 01234 294873 to get an idea of what band we estimate your EPC may be before you book an EPC.

In most cases the cost is nil. A full house survey will determine if there would be a contribution to pay.

You are under no obligation to proceed should you have a survey.

What's the difference between ECO4 and GBIS?

ECO4 is targeted towards low income households and provide a whole house energy saving improvement package that may also include heating. The Great British Insulation Scheme provides single insulation measures improvements only and is not necessarily means tested.

Under GBIS, the property would still need to qualify in terms of having  EPC rating of D -G and being in council tax band of A – D.
