"Ron and his team have been fantastic, not only is the work they have done top notch but they have been able to adapt to the changing requirements of the job every single day."

"Very pleased with the job Ron completed for us putting new lights up and adding a power extension point. Good communications and a reasonable price. Would use again."

"We contracted Ron to work on our whole house renovation. The job included ripping out all of the old wiring, and re-wiring the house, including a new consumer unit. Ron took great care and pride in our house, completing all work to a very good level. Ron had a great level of knowledge which he politely shared with us and we used this expertise to make many decisions in the house."
