As energy costs continue to impact households across the UK, government initiatives like the Great British Insulation Scheme (GBIS) are providing crucial support to help homeowners improve their property’s energy efficiency. But what exactly is GBIS, and could your home qualify for free or subsidised insulation? Here’s everything you need to know about this important energy efficiency programme.
What is the Great British Insulation Scheme?
The Great British Insulation Scheme (GBIS) is a UK government initiative launched in 2023, designed to help households reduce their energy bills through improved home insulation. Running alongside the ECO4 scheme, GBIS specifically focuses on installing insulation measures in homes across England, Scotland, and Wales.
Unlike income-based schemes, GBIS has a broader eligibility criteria, making insulation improvements accessible to a wider range of households, including those in Council Tax bands A-D and social housing tenants.
How Does GBIS Work?
The Great British Insulation Scheme operates through energy suppliers who are obligated to fund insulation improvements in qualifying properties. These suppliers work with approved installers to deliver high-quality insulation measures at no cost to eligible homeowners and tenants.
The scheme prioritises:
- Cavity wall insulation – Filling gaps in exterior walls
- Loft insulation – Improving thermal performance of roof spaces
Who Can Benefit from GBIS?
Primary Eligibility Criteria
GBIS eligibility is broader than many energy efficiency schemes:
Council Tax Band Eligibility:
- Properties in Council Tax bands A, B, C, or D
- Must be your main residence
- Located in England, Scotland, or Wales
Property Requirements:
- Must lack the specific insulation measure being installed
- Property must be suitable for the proposed insulation type
General Eligibility Route
Even if you don’t meet the above criteria, you may still qualify through the general eligibility route if your property:
- Lacks adequate insulation
- Would benefit from the proposed measures
- Meets technical installation requirements
What Insulation Measures Are Available?
Cavity Wall Insulation
Perfect for properties built between 1920-1990 with unfilled cavity walls. This measure involves injecting insulation material into the gap between exterior and interior walls, significantly reducing heat loss.
Benefits:
- Reduces heating bills by up to £395 per year
- Improves home comfort and warmth
- Quick installation (usually completed in one day)
- Minimal disruption to daily life
Loft Insulation
Suitable for properties with accessible loft spaces and inadequate existing insulation (less than 270mm depth).
Benefits:
- Can save up to £355 annually on heating bills
- Prevents heat loss through the roof
- Improves temperature regulation throughout the home
- Reduces condensation issues

Common GBIS Questions
“Is GBIS Really Free?”
Yes, for qualifying households, GBIS-funded insulation is provided at no cost. There are no hidden charges or repayment requirements.
“How Long Does Installation Take?”
Most insulation measures are completed quickly:
- Cavity wall insulation: 1-2 days
- Loft insulation: 1 day
“Will It Disrupt My Daily Life?”
Minimal disruption is expected:
- Cavity wall and loft insulation cause little disturbance
- Solid wall insulation may require temporary relocation of furniture
“What About Warranties?”
All GBIS installations come with comprehensive warranties, typically 25 years for cavity wall insulation and guarantees for workmanship.
Is GBIS Right for Your Home?
GBIS is particularly beneficial for:
- Older properties with poor existing insulation
- Homes in Council Tax bands A-D with high heating costs
- Social housing tenants struggling with energy bills
- Properties with single-glazed windows and other heat loss issues
The scheme offers an excellent opportunity to improve your home’s energy efficiency without the significant upfront investment typically required for insulation improvements.
Technical Considerations
Not all properties are suitable for every insulation type:
- Cavity walls must have adequate cavity space
- Loft spaces must be accessible and suitable for insulation
Building Regulations
All GBIS installations must comply with current building regulations and safety standards, ensuring quality and safety.
