I have a newish house and my son (who's on an electricians course) decided to fit me a new light switch in my hallway, its a double downstairs that works to another double downstairs and two singles upstairs.
The other double works downstairs, but no lights come on upstairs, other than the bathroom! I have checked the fusebox and nothing tripped, I do know he added another earth wire, from the box to the light switch, which is chrome, he has taken it off and replaced the switch with the original, but no joy!! Please help!!
