Great British Insulation Scheme Guide IN 2025
As energy costs climb and climate concerns grow, the UK government has launched the Great British Insulation Scheme — a major program to boost home energy efficiency and cut household bills.
Designed to support around 300,000 homes, the scheme offers funding for insulation improvements such as loft, cavity wall, and solid wall insulation.
In this article, we’ll explain how the scheme works, who is eligible, and how to apply for free or discounted upgrades.

Key Deadlines and Timeline
The scheme launched in mid-2023 and is expected to run until March 2026, subject to funding availability.
However, applying early is recommended, as funding is limited and distributed on a first-come, first-served basis.

What is the Great British Insulation Scheme?
Launched as an extension of the government’s Energy Company Obligation (ECO) policy, the Great British Insulation Scheme (formerly ECO+) is designed to deliver affordable insulation to millions of homes across the UK.
Its main goal is to help households — especially those with low incomes or poor energy ratings — make their homes warmer and more energy efficient.
This initiative is part of the UK’s broader plan to meet net-zero carbon targets by reducing energy consumption from homes, which are responsible for a significant share of the country’s carbon emissions.
Who is Eligible for the Scheme?
The scheme targets households most in need of support. To qualify, your property typically needs to meet certain criteria, such as:
🏠 Eligible Council Tax Bands by Region
| Region | Eligible Bands |
|---|---|
| 🏴 Scotland | A – E |
| 🇬🇧 England | A – D |
| 🐉 Wales | A – E |
-
Low Energy Performance Certificate (EPC) Rating: Most eligible homes are rated D or below.
-
Council Tax Band: Generally, properties in council tax bands A to D in England (A to E in Scotland and Wales) are prioritized.
-
Income Criteria: Households on low income or receiving certain means-tested benefits may qualify under the “low-income group.”
It’s worth noting that eligibility can vary slightly depending on your location and energy provider.
Even if you’re not receiving benefits, you may still qualify under the general group if your property has a low EPC rating and falls within the right council tax band.

| Covers Which Insulation Types? | Loft, cavity wall, solid wall, etc. | Usually the same, depending on scheme | All common insulation types |
| Long-Term Benefit | Reduces energy bills & improves comfort | Helps tenants save on bills | Improves EPC & increases property value |
| Common Restrictions | EPC below D, means-tested | Can’t apply without landlord approval | May need tenant cooperation for installation |
| Common Schemes Supporting It | ECO4, Great British Insulation Scheme | ECO4, LA Flex (via landlord) | ECO4, GBIS, Green Homes Grant (if active) |

What Insulation Measures are Offered?
The scheme primarily focuses on fabric-first improvements — meaning the most impactful upgrades that prevent heat loss from the building’s structure. These may include:
1. Loft Insulation
Insulating your loft is one of the most effective ways to reduce heat loss. It’s quick to install and can significantly lower your energy bills.
2. Cavity Wall Insulation
Homes with uninsulated cavity walls can lose a lot of heat through the walls. This measure involves filling the gap between the inner and outer walls with insulating material.
3. Solid Wall Insulation
If your home was built before the 1920s, it might have solid walls. These can also be insulated, either internally or externally, although the installation may be more complex.
4. Other Upgrades
In some cases, the scheme may also offer measures like draught-proofing or installing smart heating controls to improve energy efficiency.
How to Apply for the Great British Insulation Scheme
Check Eligibility
You can use the government’s official tools or contact your local council to see if you qualify.
Contact an Energy Supplier or Scheme Provider
The scheme is delivered through major energy companies. Even if you’re not a customer, you can apply through any obligated supplier.
Book a Home Assessment
A professional assessor will evaluate your property’s current insulation and EPC rating.
Schedule the Installation
If approved, a certified installer will carry out the insulation work at no cost or heavily subsidized rates.
Many households won’t have to pay anything, but if your property requires more extensive work, there might be a partial cost — which will be discussed upfront before any work begins.

What are the Benefits of Joining the GBIS Scheme?
Participating in the Great British Insulation Scheme offers several long-term advantages:
- Lower Energy Bills
Insulating your home can cut annual energy costs by hundreds of pounds, depending on your property type. - Warmer, More Comfortable Homes
Better insulation helps maintain a consistent indoor temperature, reducing cold spots and draughts. - Environmental Impact
Reducing energy consumption also lowers your household’s carbon footprint, contributing to national climate goals. - Increased Property Value
A higher EPC rating can make your home more attractive to buyers and tenants.
How GBIS Scheme is Different from the ECO4 Scheme?
While both the ECO4 and the Great British Insulation Scheme aim to improve home energy efficiency, there are some key differences:
- ECO4 is more comprehensive and typically reserved for households on low incomes or benefits, offering a wider range of improvements like boiler replacements and renewable energy solutions.
- The Great British Insulation Scheme is broader in reach, including households that might not qualify under ECO4 but still need help with basic insulation.
In some cases, households may be eligible for both schemes, so it’s worth exploring all options.
Frequently Asked Questions
Can I apply if I’m not on benefits?

Can landlords apply?
Yes, landlords can apply on behalf of their tenants, but consent may be required, and the property must meet certain criteria.

FAQ
Can renters apply for the Great British Insulation Scheme?
es, in many cases renters can apply, but they’ll need the landlord’s permission. The scheme can cover part or all of the insulation cost, depending on eligibility.
Does the Great British Insulation Scheme cover older, hard-to-insulate homes?
Yes, certain older properties, including those with solid walls or non-standard construction, may qualify for tailored insulation solutions. However, the type of insulation funded will depend on your property’s survey results.
Will the Great British Insulation Scheme affect my energy bills during installation?
No, your energy bills won’t increase during installation. In fact, most households see lower bills within the first month after the work is completed.
Can I combine the Great British Insulation Scheme with other government grants?
Yes, in some cases you can combine it with other grants like the Boiler Upgrade Scheme or ECO4, but you’ll need to meet the specific criteria for each.
How long does it take from application to installation?
The timeline varies, but most households move from application to completed installation within 6–12 weeks, depending on survey scheduling and installer availability.
What happens if I move house after getting insulation under the scheme?
If you move, the insulation stays with the property and continues to benefit the next occupants. You won’t be required to repay the grant.
