“Our advice is - don't try and do a whole house insulation project without a knowledgeable engineer and project manager, and we thoroughly recommend Ben Foster at Tactical Energy.

We truly could not have done the project without Ben and feel he was worth every penny (if not more) of his very reasonable fees. We now have a wonderfully warm insulated house and are very happy that the work done was of the highest standard, as Ben has checked on it every step of the way.


The bonus is that Ben is also a very friendly and lovely person who you can have a coffee with, whilst discussing your house progress!”
