I don't think it would help the OP Murdoch as he's from Northern Ireland which have a different set of building regs. Technical Booklets 2012 ? Building Control NI A quick look through technical document R page 46 and I think they have different requirements on heights of accessories for example.
How stupid can the UK get. Surely 1 set of regs would be best.... no wonder the incomers get confused then don't give a txss!
