Thanks for the advice chaps.I would consider myself 'competent ' in basic installations and anything 'of the norm' but as beanzy asks i have not got ,or could even contemplate testing
.Actually went to look at the office today and although the actual wiring and connections looked well within my capabilities,the fact that the 'suspended/false ceiling is actually screwed to the flat roof joists and the existing lighting (2x double florrys) are thus screwed to the side of the joists,facing sideways! ??? I therefore have know idea what his options are,there is literally no room to even get my fat fingers in to change the faulty tube
But i have at least told the missus that ,although i might be capable of doing something(what,i dont know!) it is not down to me to do it,its up to her boss .The missus has now 'had it out' with him
and included the advice you lot have given,ie testing legal lighting requirements etc,and when the bosses partner returns from his hols' has promised to refit and rewire the office.(we 'll see!!!!!) Once again,thanks for all your help and advice,its been most useful.(even if it is to just shut the wifes moaning up!)
