This was our second year using them as I though give them the benefit of the doubt and they yet again tried to add an additional charge of £39.99 for ! SOCKET TESTING ! which they only inform you of in very small print and state ! "if you don't tell the visiting engineer you don't want it he will perform it as standard" ! but in reality the visiting engineer performs no other additional works on the sockets or plugs as the machine they use for the PAT testing performs a same loop impendence test, the socket testing is the same as what a small cheap £5 3 light plug in device from any hardware store can tell you but they don't do this either. Also the microwave testing is another rip off for an additional £9 as this is not performed correctly as a trained electrical fitter I had to explain the correct procedure for testing a microwave safety to them two years consecutively. Once you call them and highlight the above issues they are quite rude and blunt but will reduce the invoice immediately, so they obviously know this is happening and just try it on as imagine how many people / companies just swallow the costs due to not knowing. Candidate for Rogue Traders I would say. We will never use this company again for testing of any kind, please use a online search to read reviews of this company before using.
