In actuality...
All work carried out by N G Safety is hurried, improvised and dubious at best. They are unreliable, lack even the most basic of electrical and testing knowledge, and about as professional as a McDonalds employee on their first day at work. They comprise a single staff member who rarely answers his 'phone, and when he does, is utterly unintelligible. Written communication is also ruled out by his illiteracy. Nick Gligs is entirely unqualified for this job and should be avoided at all costs if you at all value your time, money and wellbeing. He's so useless that he'd have difficulty in tagging a dead body at a mortuary, let alone tagging electrical equipment. About the only thing he's good for is giving money to Indian spammers.
