What improvements are people going to make to their insulation ? I have some areas of my loft that do not have 270 mm so that’s an obvious place to start, but should I go higher than 270 mm ?
My RetrofitWorks survey suggested finding out if the cavity wall insulation done some years ago was patchy or had slumped, is anyone else going down that route ?
How about an extra internal wall insulation. Then there’s draught proofing… blocking the unused fireplace, the list is long...
