Underfloor Insulation Grants
What is Underfloor Insulation?
Underfloor insulation is a highly effective way to stop heat escaping through your floors — particularly in homes with suspended timber flooring. By installing insulation beneath the floorboards, it blocks cold air from entering and keeps warmth inside your home.
Thanks to the ECO4 and GBIS government schemes, eligible homeowners can have underfloor insulation installed completely free of charge.
It’s especially beneficial for older properties with draughty ground floors or low energy ratings.
✅ Prevents heat loss and cold draughts through the floor
✅ Quick, professional installation with little disruption
✅ Fully funded for qualifying households via ECO4 or GBIS
Is Underfloor Insulation Suitable for My Home?
Underfloor insulation is particularly effective in homes with suspended timber flooring, which is commonly found in properties built before the 1980s. These floors often allow cold air to circulate from below, leading to chilly rooms and higher heating costs.
You’re likely a great candidate for underfloor insulation if:
✅ Your ground floor is made of wooden floorboards rather than solid concrete
✅ Your property was built before 1980
✅ You experience cold floors or draughts in downstairs rooms
✅ Your EPC rating is D, E, F, or G
✅ There’s accessible space below the floor (e.g. crawl space or cellar)
Not Sure If Your Floors Qualify?
No problem — we’ll arrange a free home survey to check your floor structure, access points, and eligibility before any work is carried out.

Why Choose Underfloor Insulation?
Lower Heating Costs
Insulating under your ground floor helps trap heat inside, reducing energy waste — especially during colder months.
A Warmer, Cozier Home
Say goodbye to chilly floors and draughty rooms. Underfloor insulation keeps temperatures stable and makes your home feel cosy all year round.
Lower Carbon Footprint
Improved insulation means less energy use, helping you reduce emissions and live more sustainably.
You May Also Qualify For:
- Cavity Wall Insulation – Ideal for homes built after 1920 to reduce heat loss through external walls.
- Loft Insulation – Stops up to 25% of heat escaping through the roof.
- Internal Wall Insulation (IWI) – Best for homes with solid walls that lack a cavity.
- Room in Roof Insulation – Keeps attic or converted loft rooms warm and compliant.
