What is Home Insulation?
Home insulation acts as a thermal barrier, reducing heat transfer between the interior and exterior of your home. By minimising heat loss in winter and heat gain in summer, it keeps your home comfortable and energy-efficient throughout the year.

Types of Home Insulation We Offer
- External Wall Insulation (EWI)
A cost-effective solution that enhances energy efficiency by adding insulation to external walls, covered with a protective render or decorative finish. It reduces heat loss, lowers energy bills, and refreshes the property’s appearance—ideal for homes with solid walls lacking a cavity. - Internal Wall Insulation (IWI)
A highly effective solution for improving energy efficiency, especially in restricted areas. IWI involves fixing thermal insulation to internal walls, reducing heat loss, enhancing comfort, and lowering heating costs—ideal for solid-wall homes, though it may slightly reduce room space. - Loft Insulation (LI)
Loft insulation involves adding insulating material between and over joists to reduce heat loss, making homes more energy-efficient and cost-effective year-round. - Room in Roof Insulation (RIRI)
Designed for loft conversions, RIRI insulates sloping ceilings, walls, and dormer windows, enhancing comfort, reducing heat loss, and improving energy efficiency. - Cavity Wall Insulation (CWI)
CWI fills the gap between brick layers with insulating material, reducing heat loss and enhancing energy efficiency—ideal for homes built after the 1920s. - Flat Roof Insulation (FRI)
Flat roof insulation improves energy efficiency by adding insulation above (warm roof) or below (cold roof), reducing heat loss, preventing condensation, and lowering energy costs.
What Home Insulation Grants Are Available?
The UK government offers grants through schemes such as the Energy Company Obligation (ECO), Warm Homes Local Grants, and the Great British Insulation Scheme (GBIS). Our team will guide you through the application process to make your home insulation services London project more affordable.
Am I Eligible for a Home Insulation Grant?
Eligibility for an external wall insulation grant in 2025 depends on the following key criteria:
- EPC Requirements In the UK, every property—whether newly built, being sold, or rented—requires an Energy Performance Certificate (EPC). This certificate provides an energy efficiency rating from A to G, along with important details like energy costs and suggestions for potential eco-friendly improvements. If your property falls under ratings D, E, F, or G, it may be eligible for ECO4, GBIS, or Warm Homes Grants for external wall insulation. These grants are designed to support low-income households living in the least energy-efficient homes, helping reduce high energy bills. Not sure about your EPC rating? Check your home’s energy performance on the official UK government website: https://www.gov.uk/find-energy-certificate
- Council Tax & GBIS Eligibility – Council Tax is a UK local government charge that funds services like waste collection, policing, and schools. The amount is based on your property’s valuation band (A to H) and local authority rates. The Great British Insulation Scheme (GBIS) considers Council Tax bands when determining insulation grant eligibility. Households in lower bands (A to D in England, A to E in Scotland & Wales) may qualify. EPC ratings and other factors also affect eligibility.
- Benefit Requirements for ECO4, Warm Homes Grants, & GBIS (Low-Income Group) – To qualify for the ECO4, Warm Homes Grants, and GBIS Low-Income Group schemes, you or your tenant must meet specific eligibility criteria, including receiving certain benefits. These include:
- Income-based Jobseeker’s Allowance (JSA)
- Income-related Employment & Support Allowance (ESA)
- Income Support (IS)
- Pension Credit Guarantee Credit (PCGC)
- Working Tax Credit (WTC)
- Child Tax Credit (CTC)
- Universal Credit (UC)
- Housing Benefit
- Pension Credit Savings Credit (PCSC)
- Child Benefit (subject to income caps)
