Why Bexley homes benefit from floor insulation
Real comfort improvement
Most Bexley homes lose 25-35% of their heat through uninsulated walls or roofs. Floor Insulation cuts that loss dramatically and eliminates the cold spots and draughts that drive heating costs up.
Lower bills
Savings depend on the starting point, the measure and your tariff, so we give you an honest estimate at survey rather than a headline figure. Loft and floor insulation pay back fastest; wall insulation saves the most on solid-wall homes.
Adds value
Insulation lifts the Energy Performance Certificate score, which buyers and lenders see, and landlords need a good EPC to keep letting. We lodge the work with TrustMark so it is on record when you sell.
