Floor Insulation

Suspended timber floors with access from below (e.g. where there is an unheated basement or an accessible crawl space) can be insulated relatively easily as long as the floor joists are in good condition and show no signs of damp or rot.

*Figures are taken from Energy Saving Trust and are based on fuel prices as of October 2023. Estimates are based on insulating a three bed, semi-detached, gas-heated home.
