Loft Insulation
Buildings which have an accessible, unheated loft space can benefit from installing insulation above ceiling level.
Insulation can be fitted between ceiling joists and extra layers of insulation laid perpendicular over the joists.
*Figures are taken from Energy Saving Trust and are based on fuel prices as of October 2023. Estimates are based on adding 270mm of insulation to a three bed, semi-detached, gas-heated home which previously had 0mm of insulation.
