You can't turn down an offer like that, we had ours done a few years ago.....It does make a hell of a differenceI was in bed at 3.30AM this morning and up at 9.30AM due to bloody scaffolders putting up scaffolding across the road. Gonna be the same for the next month as all the houses in and around (including mine) are getting exterior wall insulation fitted. Got a good deal on it. Usually costs 12k but only had to pay 1k as the local government are financing it as an energy saver.
