PAT Testing is a process that can identify faults in electrical items that could potentially cause harm. Most cars are all tested every year to ensure they are safe to drive and they don't have any faults that could potentially cause harm. PAT Testing is in some respects the same, it is a series of inspections and tests on electrical items that we plug in and use quite often on a daily basis. Just like you would not want the brakes to fail in a car you are driving and cause an accident you would not want for example to plug in an iron, pick it up and get an electric shock or worse have an electrical item that is plugged in to cause a fire because it is faulty and a test could have identified it as a risk.
