Works quietly and diligently and solves problems

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.

We asked Mark to fit an induction hob where a gas hob had been. The work turned out to be non-trivial and needed difficult cutting of the worktop. He worked away diligently - it took him about four hours to complete the fitting. He was concerned to get things right, such as fitting an isolation switch for the oven that is fed by the same cable as the hob. We were very pleasantly surprised at how reasonable the cost was. We propose to use him if we need other electrical work done.

I have used Mark since 2018 and will continue to do so (he is trustworthy knowledgeable and professional) for all electrical work e.g Creating extra sockets (other electrician quotes said couldn’t be done) but Mark said can be done Extra spotlights fitted Double outside electric socket fitted. He has recently done work on my daughter's new property New bathroom light fitting after his advice on what to go with Fitted upgraded electric wall heaters, a fabulous job done so pleased. 5* service advice. No job is too big or small. Thank you again
