hi guys. i have just had an electrician come round to look at wiring up my shower fan. he said he will fit the isolator switch in the ceiling in the bathroom, i questioned this and he said everyone does this, but he would not be able to give me any certification or anything and it would be best if i said i fitted it myself if anyone asked. can the isolator be fitted in the bathroom or does it have to be fitted outside the room. thanks in advance
