I would highly recommend him.  Gillian Dawson

  • Several lights in our house began to flicker. Greg came out same day and correctly diagnosed the problem as being external. It turned out to be an ESB issue affecting several houses in the estate and was corrected. We then had Greg install two LED security lights outside, add three double sockets inside, and repair/convert recessed lighting in ceiling to LED lights. Extremely helpful with advice, prompt and tidied up after. Great work done and peace of mind. Would definitely recommend!

Greg was very careful to understand exactly what we wanted in terms of location of lights etc. and did everything spot on and exactly the way we wanted it done. Overall we were very happy with the speed of work, the

  • Would highly recommend Greg. He installed pendant lights in kitchen which required chasing the wall and plastering;he did a very neat job .He also installed lighting in a unit which was tricky however he resolved the problem. I asked him to look at a ceiling smoke detector which had a broken base and was hanging from the ceiling , he just happened to have a spare in his van and fixed it for me. His work was excellent, efficient and clean. His price was very reasonable. It is great to have a professional, reliable electrician I would not hesitate to
