So had a surveyor from The Mark Group knock on the door earlier to assess our house for 'free loft and cavity wall insulation'. He spent an hour here, testing the walls for depth, assessing loft space etc. I signed up to the scheme as he said our post code made us eligible for the free scheme.
However, I am now wondering what the catch is. Is this too good to be true? Anyone have experience of having this done? There is a 14 day cooling off period so can cancel it..
