Plugged Electrical were hired to carry out a rewire of my property. The quality of work carried out was substandard and in some cases dangerous. As we were getting electric shocks from light switches they had installed, we get an independant inspector to check his work and he was horrified. Problems included wiring blocks not secured, Fuse board incorrectly labelled, switches not earthed, cables exposed and a fake EIC report that was never submitted to the council. They also never paid their plasterer!

He didn’t try to make a mountain out of a molehill or push for any unnecessary work—just gave honest, practical advice on what to do next. Really appreciated how straightforward and helpful he was.
