Electric systems in an office need to be in good working order to meet with health and safety standards. It’s also incredibly important for the general maintenance of your building and the everyday safety of the people who use it. If you are unsure at all about the electrics, get everything rewired and start from scratch. It is going to be a lengthy and potentially expensive process but it is the only way to know that what you are doing is going to be safe.

Always employ a trained electrician to be on the safe side. It is not something that an amateur or somebody with a little bit of experience can take on. Have a look at the people you have worked with previously and see if any of them will be able to help. Alternatively, find a contractor through people you know or find somebody online using a trusted tradesmen tool.
