Mark did electrical work at both my house and my mum’s house. This is the second time I have used Mark for electrical work. He is reliable and polite and completes the work in a timely manner. He provides advice on best lighting / solutions. He purchased the lighting fitments on my behalf (saving me time & effort working out the best option). Reasonably priced. I would recommend Mark and will use him again in the future.

I recently contacted Mark for the first time to remove two ceiling lights and install two new ones. He arrived on time on the day agreed. He worked quietly and efficiently to do the work. A problem was detected with an existing dimmer switch for one of the new lights. Luckily I had a replacement light switch in the house , which Mark was able to install with no problems. All the work was completed and I am very happy with work. I would have no hesitation in using Mark for any other electrical work.

Mark was able to fit a new socket and change another with very short notice. All options and steps were described to us and the work was carried out to a high standard and with no mess.

We have used Mark before as Electrician of choice. On this occasion we needed some sockets repositioned, some sockets installed where there were no existing sockets, and electrical leads resting on top of the kitchen cabinets needed to be tidied up. In addition, we needed Mark to track down why one particular electrical circuit which powered the garage, tripped on an infrequent basis. This was a particularly difficult task because at times the circuit would trip, meaning there was no way to access the garage. If only the garage had an entrance from the house, or from the garden we would have been able to get into the garage. In the end, Mark dismantled some of the overhead door and was able to detach the garage door motor to enable the door to be opened manually. Once inside the garage, Mark was able to rectify the problem. Mark can be relied upon to work quietly and diligently, and keeps the customer advised throughout.

We had no electricity in our kitchen, especially fridge and freezer , and in our dinning room. Mark found out the problem and managed to fix everything. It was not easy as we live in an old house. Mark was very patient, explained what he was doing and job done. 👍 We are very grateful and pleased with his service. We will definitely call him again , and definitely recommend him to everyone that we know.

Mark came to repair two malfunctioning lights at our home. He arrived promptly and was courteous and thorough, explaining the problems, and what he intended to do, which he did speedily. His charges were most reasonable, and I heartily recommend him to anyone looking for an excellent electrician in the Cardiff area.

Hat Trick of Successful Visits

This was the third occasion we have called upon Mark, and it was every bit as successful as the previous visits. He fitted a new double plug socket for which he provided an electrical certificate, installed a heat alarm, and diagnosed and fixed a problem with our cooker hood. Mark always explains what he proposes to do before starting, and his charges are very reasonable.

Professional, trustworthy and thorough. Mark came out at short notice to diagnose a tricky problem with our domestic electrics and was determined to fix the issue, which he did successfully in very little time at all. Replaced two sections of wiring and got our downstairs socket circuit back up and running. Will definitely contact him again if we require any further electrical work, and will recommend him to everyone we know locally!

Mark fitted a PIR light by our front door. He arrived promptly, did a great job and was a pleasure to deal with. I will definitely use him again for any electrical work and would recommend him to my friends.
