Who prepared the plans? Are they the ones used for the Planning submission? I assume the extension is being done under Building Notice rather than a Full Plans submission? If you’ve submitted & paid the fee, you should contact & receive guidance from your LABC, as stated.
I reckon you should have had at least 2, possibly 3 inspections by now, have you actually had any? I assume that either your builder or you have actually made a Building Notice submission?

hi all, late update
i spoke to my planner who said he called building control about this he said "there is no problem with 9.5mm plasterboard to stud walls, between the ensuite there should be 50mm insulation and it should be moisture resistant."
i sumise theres nothing to say this cant be done but it is obvious it is "standard practice" and recommended from those in the trade to use at least 15m for stud walls. Its also stated by British Gypsum that this is case as well but theres nothing to say its agaisnt building regs.
I myself am going to remove (on maybe board over) with 12.5m myself and get wedi boards for the bathroom.
Do you think this is right what my planner has reported back? it seems unreal to think you can use 9.5 esp in a bathroom when its going to be tiled, even my tiler said he wouldnt tile on something so thin. It seems a grey area to me.

As I originally stated; sound insulation is not mandatory if the stud wall is between the en-suite & the bedroom it serves, only the stud walls between the w/c & another habitable room (the bedroom next door). Insulation would do no harm but, personally, I would rather he spent the extra cash overboading with another layer of 9.5mm. Building Control would not give a FF if you used 9.5mm or if it’s moisture resistant or otherwise (but yes it should be), it’s about what is accepted good practice & gives satisfactory results. Admittedly without checking back but I don’t think there was a single contributor who said 9.5mm boards on a stud wall was good idea. The combined experience on this forum is considerable & it’s outside accepted practice; your builder is being cheapskate.
It is if the stud wall is between the room with the w/c & another habitable room; it’s not compliant unless it’s Wallboard 10 with sound insulation but 15mm Soundblock is superior & probably what most would use. If your builder is saying otherwise, he’s being economical with the truth; ring your LABC & check for yourself.
Why are you having to do it?
It’s not a grey area & it all sounds very suspicious to me; I repeat my earlier questions, did you or your Builder submit a Building Notice (it’s ultimately your responsibility) & have you actually had any LABC inspections yet because by my estimation you should have had at least 2/3 by now; if you haven’t you may well have an illegal extension there!
Why are you reluctant to trust the supported advice you have already received which is also being echoed by your tiller.
I have always wondered who uses those little boards. Now I know who.
My questions is WHY?
Surely there are no benefits what so ever using those little boards. Unless you use a car for your work vehicle.
