The Best Electricians in Mayfair, Greater London, United Kingdom (2025)

Great experience using London electricians. Lucian was very helpful over email, the engineer that came to service our immersion heater was knowledgeable and professional. They were accommodating to our needs and got the report over to us hours after the inspection. Would recommend and use again.

Prompt, polite and efficient service. Lucían arrived at the agreed time and carried out the necessary work (replacement of smoke alarms) without any hassles. He had purchased the necessary items in advance as agreed. I would recommend them.

Very helpful and professional company who successfully removed three old storage heaters and installed new electric heaters in my flat. Quick communication made it easy to book an appointment. Really pleased with the service and would do business with again.

Really pleased with the service I received. Lucian has been helpful from the start to provide insight and professional suggestions on the job I needed to get done. The team arrived on time and carried out the tasks as requested. Friendly and professional service. I would use them again as well as recommend their services to others. Many thanks!

SES have been my go to electricians for many years - at minimum 7 years. Byron and his growing team and responsive, honest and professional, not to forget the great quality of their work. This is why he continues to get my business. Keep up the fab work!

We are delighted and relieved to have connected with SES Electrical Contractors, which has systematically sorted out a number of overdue issues with electrical installations including emergency lighting, fire alarm systems and most recently adding motion-sensor lighting for the communal staircase. The managing director, Byron Sanders, went the extra mile to ensure that this latest installation was the best it could be. We have now met several SES technicians and they have all been professional, capable and personable. I have no reservations in recommending the company.

I can’t thank Byron and the SES Electrical Contractors team enough! After waking up to no electricity in the house, I spent hours calling other electricians but couldn’t find anyone available. Thankfully, I was recommended SES Electrical, and from the moment I spoke to Byron, the service was amazing. He kindly offered to troubleshoot the issue over the phone before arranging a visit, patiently guiding me through a few steps and helping me resolve the issue myself! This saved me at least £300 in Electrian costs/call out fees, and was such kind and professional service which made my day. I highly recommend Byron and the SES team enough for any electrical needs!

Byron visited us to help diagnose a fault we've been having with our oven. He was courteous, efficient and communicative throughout explaining his findings in an easy to understand way. He has provided consistently excellent service in the past helping us diagnose a problem with the electrics of our boiler over the phone and assisting in the sourcing and installation of a range hood. I highly recommend SES and Byron!

Thank you so much for your help!! You saved "my life from darkness" Honestly I highly recommend him to anyone looking for quality , rapidly and excellent service. Thumbs up for your job.

Fantastic service. I wish all companies were as dedicated.

Prompt, polite expert service when electric fully failed in my flat. Up and running very quickly and full check of flat. Polite , prompt expert service at a late hour.

Had a leak under my kitchen sink for several days which was so frustrating but as soon as Naseem came in he knew exactly what to do and the whole process was so convenient and I was kept up to date with every step which gave me the reassurance I needed. The problem was fixed with amazing quality and so straight forward and quick. I am very happy with the outcome. Would definitely recommend!!! (P.s I love how there is more space under my sink now and it looks so neat compared to before :)

Cyryl is absolutely fantastic! He responded to our emergency promptly and was with us within an hour of our call. He was honest, professional and completed the work to a very high standard. There we no hidden charges and he was upfront regarding installation costs from the start. We would happily recommend him to any future customers.

Called out for an emergency decommission of a faulty old burglar alarm on a Sunday. Cyril came bang on the time estimated, was really friendly and did a quick, efficient job. Would certainly recommend

The electrician came early a few hours after I called - Cyril was very professional but also friendly and sorted out the problem quickly. Cost was reasonable particularly given it was an emergency call out. Highly recommended

The call handler was very sympathetic and professional and got a next day appointment to allow for childcare cover. electricians arrived and got the job done in about half an hour - they had to reposition two double sockets and just replace other. very friendly, efficient and showed me working sockets. Having a working kitchen again will be money well spent so I am well happy, thank you

I can only repeat the previous reviewer. It’s great to have such a reliable electrician who’s also local. Crispin is very thorough every time. He’s done electrical safety certificates, new downlighters and fixing dimmer switches for me. Really friendly too. Highly recommend! Services: Light fixture installation, Electrical inspections, Electrical outlet & switch installation

Swift professional service; Crispin inspires full confidence in his profession; extremely grateful for leaving faulty switch safe

Great work done neatly and quickly, would highly recommend to anyone!

I had several issues with the lights in my flat since moving in 3 years ago. Simply put, they did not work and each light had a mind of its own with dimmers not working most times and lights going on and off by themselves. I was given Crispins details by a friend who highly recommended him. Crispin is a highly professional individual. He is reliable and managed to complete the job perfectly (i mean, perfectly). He repaired severely complex wiring issues. He was persistent in finding a solution to each lighting problem and I am happy to report all my lights now work perfectly. He was always on time and with a positive attitude. Highly recommended!

A wonderful Job. The truncking was discretely managed in our Victorian house without looking obvious. Thoughtful and clean workers.Will be using them again.

Fantastic service - courteous and incredibly knowledgeable. Not only did they arrive within 1 hour to central London but demonstrated their vast experience and found the fault straight away. Fixed things quickly, cleanly and calmly. Explained the process professionally throughout, and was lovely and friendly. Pricing clearly stated and honest. 10/10 would 100% recommend.

Aziz arrived an hour after I called and from start to finish he was courteous, diligent, professional and knowledgeable. He explained every step and answered all of my questions with great patience. His rates are exceedingly reasonable and I would not hesitate to use his services again should I have issues in the future.

Satisfied customer. Lounge refurb. Lights, switches,sockets. Wiring, chasing in. Walls already very bad so patresses were sometimes less than completely horizontal. Morrocan sourced pendants needed reworking. Abdul did it all. Came back at short notice to fix one pendant and eventually sourced to a faulty bulb. Reasonably priced and went the extra.

Excellent service from Sharim. Our complicated shower issue was fixed in a day. He was considerate, knowledgeable and very quick!

Great service! Arrived promptly to fix electrical problems and install a washing machine. Also provided advice on several other electrical issues, would highly recommend.

Sharmin did an excellent job fixing our shower and replacing our old electric shower with a thermostatic one. Job was done in one day and he made a huge effort to not remove more tiling than was necessary. He was tidy and considerate and I would fully recommend him.

Excellent service and I was very happy with the work. The electrician is a very good guy and done the job very quickly. Definitely recommend 👌 😊

I was so pleased that I went with House Rescue for my solar install. The planning and communication was great and made complete sense, the instal itself was remarkably quick and smooth, Jack hand his team were professional, punctual and very hard working. The handover documents were complete and detailed. Overall an incredibly well organised, efficient and stress free job. I am actually looking forward to having Jack back to install the EV chargers!

Excellent service, yet again. The extraction fan in our bathroom had stopped working then a wall heater did the same thing. Appointment made promptly, electrician turned up on the dot, the price was very reasonable and the job was done to a high standard. The fan was replaced and the heater fault fixed. Frankly it is such a relief to have found this company. Though I’d rather not have anything go wrong with our electrics obviously at least I know that if they do I have a completely trustworthy source for repairs. Highly recommend.

I moved in to a house with an existing solar installation. Unfortunately, the installers had decided to focus entirely on commercial installations so were not interested in helping me to get control of the system I’d taken over. I got in touch with a number of companies looking for help. House Rescue were superb – quick replies, excellent advice and friendly service. If I needed to have a new system installed or my existing system serviced, these are the guys I’d go to.

Cannot recommend highly enough - our experience with House Rescue Electrical was brilliant from consultation to installation. The work required was a full rip and replace of the outdoor and garden lights which the team delivered with stunning results. Communication was excellent and we are thrilled with the smart home compatibility. Thank you Jack and team!

Jason was very professional, efficient and helpful. He replaced the external emergency lighting and PAT tested all appliances. We are extremely happy with his work and will be using him again. We can strongly recommend his service.

Excellent, speedy service, at a fair price from Jason, to fix a long standing issue with our bathroom spotlights, that a couple of other electricians hadn't wanted to undertake. Very happy with the speed of response and the results and would definitely use Jason and his team again. Highly recommended.

I had a couple Ring floodlight cams installed and connection of my Ring doorbell by Jason.Fantastic Electrician very pleased with his work,charges very fair price.I would not hesitate to contact this Company for any electrical work I need doing in the future.If you are looking for an Electrician look no further!

Excellent work. Highly recommended. Jason was so helpful, knowledgeable and professional. His work was very thorough, well executed and efficient.

David did an excellent job of identifying the best spot for our plug and adding it in. I thought it was an excellent touch that the plug socket colour matched the rest of the flat. Will be using them again!

Very good service. Quick response and easy to book. Marlow sorted everything out for us quickly and efficiently. Very friendly and helped explain a few things to help us in the future too. Would use again and recommend.

I was very happy with Certified Electricians London. This is the second time I used their services. David was very friendly and fast to reply to my email to replace a ceiling light. The booking was arranged promptly and the work done on time by Luke. The process was very efficient. I recommend them for electrical work and I will use them again in the future.

The first visit was from David and he got part of the lighting working for us within two hours; however, due to time constraints a return visit was planned for 8am the following day. The second visit was by Marlowe and he spent 4 hours fault finding and rectifying the issues. Marlowe was very thorough and got the lighting working properly for the first time since we moved in 7 years ago. This is the second time we have used this company and I will definitely use them again. The service is prompt, they are always on time and they just do the job in the most efficient and cost effective way.
