Energy-Saving Support for Private Rented, Owner-Occupied, Shared Ownership & Social Housing Homes
The Great British Insulation Scheme (GBIS) is a UK Government initiative designed to help households reduce energy bills and improve home comfort through funded insulation upgrades. Whether you rent, own, or share ownership of your home, GBIS could help you benefit from free or subsidised insulation, depending on your eligibility.
At Efficient Energy Homes Ltd, we help households and landlords qualify, assess properties, and coordinate the full process-all in line with PAS 2035 and TrustMark requirements.
Who is GBIS For?
GBIS is open to a wide range of property types and household situations:
Owner-Occupied Homes
If you own your home and it has a poor EPC rating (D–G), you may qualify for insulation support-especially if you are on a low income or vulnerable to cold.
Private Rented Properties
Landlords can apply for eligible tenants to receive insulation measures to meet Minimum Energy Efficiency Standards (MEES) and improve EPC ratings.
Shared Ownership Homes
Residents in shared ownership properties may be eligible, provided the EPC band and household circumstances meet the GBIS criteria.
Social Housing
Social housing tenants with properties in EPC bands D to G may qualify, particularly for cavity wall or loft insulation measures.
What Does GBIS Cover?
Unlike ECO4, which funds full whole-house retrofits, GBIS focuses on single insulation measures to deliver immediate improvements in energy efficiency. These may include:
- Cavity Wall Insulation
- Loft Insulation
- Solid Wall Insulation (where applicable)
- Room-in-Roof Insulation
- Underfloor Insulation
- Draught Proofing (in some cases)
These measures can dramatically reduce heat loss, lower heating bills, and improve comfort-especially in older or poorly insulated properties.
