3years ago we got 2 electrical sockets moved by an electrician about 1.5m further along the wall. They also installed a fused spur for an electric fireplace. We never received a minor works certificate for the work. We are now moving house. I can't get in touch with the person who did the work. Do you have to have a certificate for this sort of work? If so, can I get another electrician in to test it and provide one? Thanks.
