Customer voice from the public record
"Having tried to contact electricians in Bridgend where I live but receiving no response to telephone calls, emails, messages left, I decided to try Cardiff and found Mr Williams on Which Trusted Trader. He returned my call within hours and came and carried out the work I required within a week. He is an excellent electrician, the work was all completed to a very high standard and he was happy to give me advice on other aspects of electrics. Even though he had to travel several miles to my house, his price for all the jobs which took a few hours, was extremely fair. Mr Williams was a very pleasant and efficient electrician and cleared up after the work was finished. I would use him again 100%."
"Simply the best."
"Mark delivered the perfect service, from start to finish. Contacted Mark on the back of super high reviews from my family. His communication from the start was exemplary: quick to reply and clear with his messaging. The work undertaken involved removing alarm systems, adding electrical sockets and updating existing electrics. Mark started the work promptly and finished within the pre-estimated timeframe. The finish is of the highest quality and we’re super pleased with the outcome. Mark’s friendly, yet professional demeanour put us at ease and overall, I can’t recommend his services highly enough. Massive thanks for your work!"
"We have used Mark many times in the past - always on time and he leaves his workspace clean and tidy. He is our first choice electrician!"

We have used Mark many times in the past - always on time and he leaves his workspace clean and tidy. He is our first choice electrician!
I rang Mark on the recommendation of a neighbour, to ask whether he could do two small electrical repairs, namely mend two pull switches, one of which had stopped working altogether and the other which had developed an intermittent fault. Mark was happy to agree and a mutually convenient time was agreed for him to call. He arrived on time and was very pleasant and helpful in person. He had brought replacement parts with him, which he fitted. He completed the two jobs quickly and cleaned and tidied up. Meanwhile, we had remembered that the front door bell was intermittently faulty, so we asked if he could look at that for us. This needed a replacement part and he checked our choice with us before buying it. We felt what he charged was very reasonable and we are very happy to recommend him.
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
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.
