Paul, Thanks for reminding me.Yes you are absoulutely spot on and right in what you say; but dont you think that the doors are shut not bolted but shut quite tightly. Very nearly all building contracts no matter haow small have a one liner in them saying installation to be to BS 7671:2001. So reverse that into the fact that the building work has to comply with building regs, I think its pretty tight and I dont think I want to challeng it in the courts. After all BS 7671:2001 is only a MINIMUM standard is it not.
