What is Underfloor Insulation?
Underfloor insulation is a simple yet effective way to reduce heat loss through your floors especially in homes with suspended timber flooring. It involves fitting insulation material beneath the floorboards to stop cold air entering from below and warm air escaping.
Through the ECO4 and GBIS government schemes, eligible homeowners can get underfloor insulation installed for free. It’s ideal for older homes with poor energy performance and draughty ground floors.
Underfloor insulation is perfect for improving comfort, eliminating cold floors, and cutting heating bills, especially in winter.

Is Underfloor Insulation Right for My Home?
Underfloor insulation is ideal for homes with suspended timber floors, which are common in properties built before the 1980s. These floors often let in cold air from below, making your home draughty and harder to heat.
Here’s when underfloor insulation is most suitable:
- Your ground floor is made of timber floorboards, not solid concrete
- Your home was built before 1980
- You notice cold floors or draughts in downstairs rooms
- You have a low EPC rating (D, E, F, or G)
- There's access beneath the floor (a crawl space or cellar)
Not sure if your home is suitable? Don’t worry — we’ll carry out a free survey to assess your floor type, access, and eligibility before any work begins.
