ECO Scheme External Wall Insulation, How Homeowners Can Get Government Funding
Homeowners in the UK may qualify for free or subsidised external wall insulation under the ECO4 scheme, the Great British Insulation Scheme (GBIS) and certain local authority funding programmes. These grants aim to reduce heat loss, increase EPC ratings and cut energy bills, especially for older homes with solid brick or solid stone walls.
Eco Renewables UK provides eligibility checks, surveys and grant-funded wall insulation installations nationwide: apply for ECO4 funding.
What Is External Wall Insulation Under the ECO Scheme?
External wall insulation (EWI) is an energy-efficiency upgrade applied to the outside of a property. It involves fixing insulating materials to the exterior walls and covering them with protective, weather-resistant render.
Homes built before 1920, which typically have solid walls, lose a significant amount of heat and qualify for insulation funding through the ECO scheme external wall insulation programme.
EWI improves:
- Heat retention
- Structural protection
- Energy bills
- Home comfort
- EPC rating
- Home value
Many homeowners do not realise that they may be eligible for government insulation grants UK that can cover a large portion of the installation cost.
ECO4 Scheme for External Wall Insulation
The ECO4 scheme is a government programme focused on helping low-income or energy-inefficient households upgrade insulation and heating systems.
External wall insulation is one of the most effective measures funded under ECO4 because solid walls lose heat rapidly.
To qualify for ECO4 external wall insulation, you may:
- Have an EPC rating of D, E, F or G
- Receive income-related benefits
- Have a household income below £31,000
- Live in a home with solid walls or poor insulation
- Use qualifying heating systems

Great British Insulation Scheme (GBIS) for External Wall Insulation
The GBIS scheme also offers funding for external wall insulation, specifically targeting:
- Homes in council tax bands A to D (England), A to E (Scotland and Wales)
- Homes with high heat loss
- Low-income households
- Properties with insufficient insulation
