Floor insulation involves adding insulation materials under ground floors or between joists in suspended floors. Up to 15% of home heat loss occurs through uninsulated floors, particularly in older properties with suspended timber floors or solid concrete floors.
Floor insulation can save £100-£200 per year on heating bills and significantly improves comfort by eliminating cold floors and draughts. It's eligible for ECO4 and GBIS grants when combined with other insulation measures.

How Floor Insulation Works
Suspended Timber Floors
For homes with suspended timber floors, insulation boards or mineral wool are fitted between the floor joists from below (if accessible) or by lifting floorboards from above. This method is common in Victorian and Edwardian properties.
Solid Concrete Floors
Solid floors are insulated by laying rigid insulation boards on top of the existing floor, then covering with a new screed or flooring. This raises floor height by 5-10cm, so door heights may need adjusting.
Installation Process
A surveyor assesses your floor type and recommends the best method. Installation typically takes 1-2 days per room. The installer ensures proper ventilation is maintained to prevent damp issues.
