It's something we all take for granted, something we generally don't even think about. Computers, Power Tools, Lighting, Heating and even the kettle we use to make the tea. They all just work, don't they? The only time we tend to realise just how much we rely on electricity is when all of a sudden, someone switches it off and we are usually plunged into chaos and darkness! So how do we ensure that the lights stay on, that the computers keep running and that the people who use an electrical installation can feel safe in the knowledge that if something does go wrong, any disruption will be minimised and that it's safe for everyone to plug in and use electrical equipment? Simple really, get it tested!
