Hi
Our house is a 2001 build (Persimmon Homes I think) property. Do ALL new houses have CWI? I read somewhere, that it's not a legal obligation to have CWI, but they must meet minimum insulation requirements. It mentioned that they sometimes use thicker thermolite blocks to help insulation.
How can one find out whether CWI is fitted?
Thanks
