Garyo/Cyclone,
Thanks for taking the time to respond. Maybe I didn't make it clear in my initial post but the reason for the post was just to find out if anyone had experience of challenging Building Regs years down the line, to which Jeds cleared things up. I'm not ready (yet) to ask for assistance from folks on here regarding the actual workmanship. But that time will come.......soon!!!
Thanks again
Reading it again you simply have a disclaimer from the homepack outfit that they were not able to inspect the superstructure of the roof.
However what should have been provided to them was a completion cert by the local authorities stating the work was done to building reg standard.
These thing are very important docs and should have been passed on to you. You need to contact the LA and confirm if a completion cert was issued, and get a copy if possible.
I have done 2 such conversions, one from scratch and one to rectify a dangerous conversion that had been done without control. The dodgy one was obvious to anyone
He has allready done that and it has been confirmed that building regs were passed. The question was whether there was any claim on building control because they (not for the first time) passed a pile of crap. Unfortunately there is no chance of a claim because it's out of time and in any case - as somebody else pointed out - it is quite possible to build a pile of crap that does pass the minimum requirements.
