I struggle to see how the previous owner and/or their builder could have done this without the knowledge of the Building Inspector assigned to the job.

Does the new owner have a claim for liabity against the Council?]]> New Extension built without Insulation!

Much like a House buyers £800 'professional full survey' , not worth a toffee.
Hurrah for public accountability and the world of box ticking paper tigers
My experience of BC officers is many ( not all ) have little interest in anything to do with quality installation of insulation. Many seems bewealdered when I do anything above that required by B regs, such as 3G or additional insulation.]]> New Extension built without Insulation!

Yes, but this isn't 'quality installation of insulation', it's none at all!

Mike, at very least I would refer it to the relevant BCO for their comment (after checking that it was LA, not independent BCO)]]> New Extension built without Insulation!

You would be difficult to prove the BC officer or the council was negligent in order to get a claim from the council.

IMO the previous owner who caused the work are at fault.]]> New Extension built without Insulation!

That seems a very logical response and I think you may well be right , particularly about proving liability. On my jobs however (in the same area) the BC always insists on seeing the insulation at regular intervals. This is two storey extension, two rooms up two rooms down with three of the four walls being external. Lots of oppertunities for all those involved to see what was going on. That's why i'm so cynical about it.]]> New Extension built without Insulation!

OK, a lot of my jobs are *purely* insulation, so maybe I am spoiled, but BCOs always tell me what they want to see at what stage, and we tailor visits accordingly. I am surprised given the importance of AD L that they wouldn't have asked to see at least a sample of what was going in and how (maybe you've not found the 'sample', Mike - and they just didn't do the rest!!)]]> New Extension built without Insulation!

I would have thought a visit at wall plate would be statutory, where any cavity issues would become clear.


Posted By: Mike Georgeat least where weve drilled some holes.


Have you considered they may have used cavity bubble wrap(Alreflex2L2 or simular) if you’ve only drilled a small inspection hole expecting to see PUR pulling back through on drill bit, that wouldn’t happen with this product. Maybe strip a couple of tiles and have a look at the wall plate. I think BCO would have asked for whatever insulation was used must be extended to WP.]]> New Extension built without Insulation!

Check approved drawings, check with BCO.
