Reason for only a 3 star review is as follows. Didn’t rewire a light that said would as said shouldn’t be just plugged in to a socket and was included to be done in the quote. I messaged Chris as the lights timings not set up correctly even though he said he had to send me the instructions so I could do it and I saw him with the instructions but I never got any response so I had to spend time up a ladder sorting myself using guesswork. There were a couple of other issues but out of characters !!

Although seemingly very professional initially, arrived on time to quote, supplied a reasonable price, agreed time and date to commence work. Unfortunately week 1 failed to show, lame excuse ‘ van issues’ possible of course, week 2, failed to show again, no excuse, no response to phone calls, didn’t have the courtesy to return calls or convey reason for failing to attend, rude, so I can’t comment on the standard of his work but if it’s as poor as his customer service then avoid this electrian
