Re:Insulation Hi Paul,
The building regulations that apply are the ones in force when the plans are approved, not when the houses are built. In your case it sound like several years have elapsed. I know some developers build in phases over a number of years. There is a Jones Homes site near me that has been on the go for over five years.
It is recognised that cavity wall insulation is the easiest way to meet the target U levels, but if this is not installed, you should simply ask how it is achieved? This seems like a reasonable question, but as they have yet to provide a bath panel I don't suppose they will be too forthcoming with an answer.
BTW Go to the NHBC about the bath panel if the builder is not being helpful. You could also buy one your self and claim it back theough the small calims court online - make sure you have all the necessary evidence .
