Measured after survey
Commercial buildings are measured and priced per m² after a survey, and works are planned around how the building runs.Recommended
The insulation we usually recommend
Floors over garages and open space
Insulating floors over unheated garages, passages, undercrofts and overhangs.
External wall insulation (EWI)
A complete certified build-up of insulation board, mesh and render from one system holder.
Commercial flat roofs
Warm-deck and tapered insulation with new waterproofing.
Acoustic insulation
Sound insulation in floors, party walls and ceilings.
Funding and VAT
0% VAT on energy-saving materials applies to homes, so commercial work is normally standard-rated. We'll set out any funding that may apply after the survey.Commercial and public buildings
