A great team!
Ben and Mark have recently completed the refurbishment of our home electrics. We have renewed our kitchen/diner; Ben repositioned all the electrical points in the kitchen to match the positions of the new integrated appliances and powered sockets for the island. The Kitchen lights were upgraded to LED and Ben powered and hung a flat screen TV for the diner. They upgraded the 20-year-old central fuse boxes with up to date safer solutions, replaced broken bathroom extractor fans and improved light fittings to LED. Any unsafe circuits were addressed and repaired and the only electrical snag that arose during the fitting of the new kitchen was quickly addressed so the project could complete promptly. Ben and Mark work seamlessly together and not a moment is wasted. We are delighted with the quality, speed and timeliness of their work and will be in touch with them again when we need electrical services.

Superb
Second time I have used J&M Electrical because their work is superb, and I can’t recommend them highly enough! Mark & Ben replaced my very old storage heaters with new Dimplex Quantum, fitted an immersion timer and also went above & beyond. Even hanging a massive full-length mirror on the wall in the living room. And re-attaching the heated towel rail in the bathroom which had come loose. Installation is never straightforward, because I live in an old converted warehouse. Super helpful and kind. Thanks again chaps

Lennon & McCartney, Laurel & Hardy, Mark & Ben
Great duos like Mark & Ben from J&M Electrical, as well those others Lennon & McCartney and Laurel & Hardy, show the whole is greater than the sum of the parts. Mark and Ben's qualities complement each other. You find the job not only gets done well, but often they come up with a better plan than your original idea, and you get to a better solution you hadn’t thought of yourself. And, (don’t tell them I said this), they are actually good to work with as people. We repeatedly re-use them for a reason. It’s fair to say, these guys really do come highly recommended.

Excellent, friendly service
I'd highly recommend J&M Electrical. Mark & Ben installed Dimplex Quantum storage heaters and a Q-Rad for me today. They've been very helpful in email correspondence beforehand, and were efficient, friendly and helpful today. They went above and beyond and helped me with a couple of other bits and bobs too.

Repositioning electric meters
Mark & Ben from J&M Electrical were not only extremely competent but also unfailingly courteous and considerate. I needed to have the main supply, consumer unit and smart meter moved from its old position to a new one 20m away. I had been a bit concerned but they were so reassuring and efficient I soon realised that I had nothing at all to worry about. They arrived promptly and kept to the original estimate even though extra work was involved. Mark answered the few questions I had simply and clearly. I wouldn’t hesitate to use them again and can wholeheartedly recommend them.

Very professional, Knowledgeable, helpful, good value service
J & M Electrical installed a Dimplex storage heater for us recently. We were so impressed with them from initial contact to completion of the work. We knew very little about storage heaters and Mark gave us great advice on the best model for our size of room. He seemed to know everything there was to know about Quantum storage heaters! Once we had made our decision, Mark gave us a very competitive quote the next day and fitted us in very quickly. At installation Mark and Ben were very organised, knowledgeable, friendly and helpful and they didn't complain about having to come up 5 flights of stairs with the heavy bricks, etc! Once the heater was fitted, Mark spent time explaining all the settings, etc and suggested which programme would be best for us which was very helpful. The work was finished to a high standard and the room left tidy. The same day Mark emailed us all the information we would need to register our new heater for an extended guarantee, including a very useful link to Dimplex! We would have no hesitation in recommending their services to others and we will definitely use them again for any electrical work in the future.

A brilliant and very friendly service!
J & M Electrical recently completed a desperately needed full house rewire for myself and my husband on our recently purchased 134 year old property. From our first meeting Mark has shown the utmost knowledge and professionalism during the process, with very fair pricing too. As first time homeowners we are particularly grateful to have had J & M Electrical recommended to us by someone we know and were very pleased that Mark could alleviate our anticipation about the first big home improvement task we would be about to undertake. He listened to and advised very well on what we wanted, and was very flexible to change a few things which we had requested at short notice. Whilst moving out during the time of the work being done (which was our choice) Mark ensured we were fully informed on what was happening on a daily basis, communicating with updates and photos which we were delighted to receive. Our work was finished on time to a very high standard which other tradesmen we've had round since have even taken the time to notice and compliment. He also left our house very tidy and presentable, which is something which can be rare to find with tradespeople these days! We would not hesitate to recommend J & M Electrical for any electrical jobs you might need and we will be sure to call on his services again in the future.

Great work as quoted
Arrived at the agreed time and I received the quote the following day. Extremely polite, tidy and cleaned up after themselves. The work was completed to a high standard and was emailed the certificate the next working day. I would recommend them and would use them again

Great experience
I contacted J&M electrical as I needed the consumer unit to be relocated as it was restricting access to the electricity meter, preventing the installation of a smart meter. Ben and Mark were very friendly and helpful right from the beginning, responding swiftly to my initial enquiry and then quickly arranging a site visit and preparing a quote promptly. On the day of the work, they arrived promptly on time and did a great job of moving the consumer unit to a much better location and completed the work swiftly, professionally and very tidily. Overall, I had a great experience using J&M Electrical and would be very happy to use them again and would happily recommend them to anyone else.

Excellent, friendly and good value service
Mark and Ben did an excellent job of replacing my light fittings and installing a complicated set of Lightwave smart switches - more complicated than any of us expected! They persevered and got everything working perfectly and were friendly and good humoured throughout. Despite the extra time they stuck to the quoted price, which was already very good value compared to previous electricians I have used. I will certainly use them for any future electrical work, and have no hesitation in recommending them.

So pleased we chose J&M Electrical West London Ltd!
J&M Electrical carried out a full house re-wire for us in August 2022. We found Mark and Ben to be friendly and very professional. The quality of their work is very good and they were punctual and respectful of the house- especially as we were living in the house during the re-wire! Mark and Ben's work was tidy and due to their wide experience and knowledge they were able to find the best ways to complete the work both on time and budget and also with the minimum of fuss and disruption. The quote from J&M Electrical West London Ltd was competitive (in fact I think they did a bit of extra work without charge!). We would recommend J&M Electrical without hesitation if you require any house re-wiring!

Storage Heaters Upgrade
J&M Electrical supplied and installed 5 Dimplex Quantum storage heaters. While visiting for the quote they thoroughly explained what work was required and were happy to answer any questions. I couldn't be more satisfied with the installation and how tidy they left my flat at the end of each day. At the end of the installation, they stayed with me until I fully understood the programming. I plan on using them again.

Superb service
I had both my Dimplex storage heaters replaced, and from initial contact through to the installation visit, Mark has been so helpful. He answered all my queries efficiently, gave a accurate quotation and kept me informed of the whole process regularly. At installation, both Mark and Ben were so organised, knowledgable about the products, and respectful of my property. Nothing was too much trouble - they happily carried all the heavy bricks up and down two flights of stairs! Mark demonstrated how to use the heaters before leaving site and I received the follow up information/link needed to activate Dimplex’s warranty from Mark the very same day. I was so impressed by the professionalism of the company overall and would happily recommend them to others - I also asked for a quote for a future project as they were so trustworthy.
