Is installation testing a legal requirement?
There is no legal requirement to have electrical testing carried out, however you do have a duty of care to ensure your electrical system is safe at all times The best way to show this is to have a Periodic Test and Inspection carried out, together with action to remedy any faults identified as a result of testing If an accident does occur, where electricity is found to be the cause, then the duty is yours to show you did all you could to avoid the accident/offence.
