The Great British Insulation Scheme (GBIS) is a UK government initiative that provides free or subsidized insulation to improve home energy efficiency. One of the key measures covered is External Wall Insulation (EWI), which helps reduce heat loss, lower energy bills, and enhance home comfort, especially for solid wall properties.

What is External Wall Insulation?
External Wall Insulation (EWI) involves applying an insulating layer to a home’s exterior walls, preventing heat loss and improving energy efficiency. It is ideal for homes with solid walls, which lack cavities for traditional insulation.
How Does External Wall Insulation Work?
- An insulating layer (such as mineral wool or expanded polystyrene) is applied to the outside walls.
- A protective render or cladding covers the insulation, providing durability and weather resistance.
- The process improves energy efficiency, prevents dampness, and enhances the home’s appearance.
Eligibility for External Wall Insulation Under GBIS
To qualify for External Wall Insulation (EWI) through GBIS, homeowners or tenants must meet these criteria:
| Eligibility Criteria | Details |
|---|---|
| Property Type | Suitable for solid wall properties (brick, stone, or concrete homes built before 1920). |
| Energy Performance Certificate (EPC) Rating | Homes with an EPC rating of D, E, F, or G are prioritized. |
| Homeownership Status | Available to homeowners and private tenants (landlord approval required). |
| Income Level | Focused on low and middle-income households, especially those receiving government benefits. |
