Great Customer Service
Customer Service
Jamie and Steve were brilliant. They sought to get some power back for me when I had a major failure. They arrived at the time they said and managed to isolate the fault and get most of my power up until they could come back to finalise the solution. They also spent a day installing a new fuse board and lights and power sockets in my kitchen. They are both courteous and have a great customer service ethic. They left my house clean and tidy and me feeling very confident about the work that they did. The price remained as quoted. I have no hesitation in recommending them. As a woman living on my own I felt very comfortable with them in the house. Very trustworthy.

They did some garden wiring as well as wiring up our hot-tub. Very happy with the work. They are prompt on time and can't fault them.
