when i worked on a job in nottingham the appartments were divided by double fire boards at each side and void in between, we had to fit these special dry lining box's. but that was to seperate dwellings. is this gonna all be the same dwelling?? your saying that the existing exterior wall is now an interior wall and you wanna fit sockets on it and labc say you cant?? sound like tripe to me!! but then im often wrong!!

I've never heard this before but then again i don't often ask that sort of question. Did LABC give you a reason?. If it's fire protection you can either use special intumescent seals in the boxes (pricey) or fireseal sealant in all the holes. The intumescent seals are the right size to fit into a KO box and are the same fabric as smoke hoods. Easy enough to fit as long as you're not fitting flat plate into 25mm but expand to seal the aperture when subjected to fiery heat.

yeah we fitted the dry liners with intermescent seals on them, thats was only because there was another dwelling next door tho.. is this just an extension thats still part of the same dwelling?

so if its classed as the same dwelling and not another property then dont see why it needs any more protection than any other socket etc??

yeah that van is a tranny connect with a focus rs turbo lump bolted in getting sideways! driven by tiff needel, have a look on youtube!!

Fire protection should only be necessary (i'm pretty sure) if there is a danger of fire passing through a fire rated wall ( or ceiling) to a normally inhabited area. I have had recommended that I shouldn't recess sockets because of damp but this shouldn't come up in new build.

Marty Is this a timber framed extension or a brick/block with drylined walls?
