Insulation is always the first type of measure to consider when trying to cut your energy costs or carbon emissions. Under-floor Insulation is an effective insulation measure, particularly if you have a basement or crawl space beneath a timber floor.

Costs and Benefits

A typical house will cost about £600 if you can easily get below the floor. If you have to lift floorboards then you will need a quotation. With normal weather and standard occupancy, you should get your money back in less than 10 years*.

Materials and Guarantee

All under-floor insulation done by ecologic-energy uses materials approved by the BBA, the UK’s body responsible for testing and approving materials. ecologic-energy is also accredited by the BBA as a PAS2030 installer.


Installation for a typical home takes less than 2 days. Watch the short video for details of how it is done (its from Australia, but uses the same material as we do).
