I can see the point of the guy doing it.
Undoubtedly there's going to be a lot the old plastic CUs fitted during quarter one, where the design section of the EIC is filled out as December. A lot of these will be installers trying to get around the change in regulations. These are basic domestic works, not big projects with tens of DBs which is designed a long way in advance, it is unreasonable for most (not all, I will concede) domestic jobs to have a design date much in advance of the construction date.
The guy doing the job probably doesn't want to end up lumped together with the installers who will be doing this kind of trick
