I have had an ongoing issue with Miller homes for over 3 years concerning levels of condensation. After getting nowhere I reported the issue to NHBC who attended my property today, along with Miller Homes reps who I was unaware were also attending. The opening gambit from NHBC was 'your policy doesn't cover condensation' ! I asked both NHBC and Miller what I should do about the 8inches of condensation on my windows and received the very technical response to leave my windows open. This defeats the purpose of the super efficient insulation we have and the fact its not particularly practical in the west of Scotland. Can anyone advise if I can take this anywhere else?

Miller and the NHBC should be looking for the causes of the condensation.
It could be down to you, drying clothes indoors, not using extractor fans etc.
More likely is that you have a plumbing leak somewhere that is increasing the moisture in the air.
It should be checked out.
