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

Excellent, reliable and dependable team. Can always rely on PJ Electrics to do a good and professional job to a high standard and at a competitive rate. Particular thanks to Ryan George for carrying out our electrical survey and providing sound advice ahead of a flat refurbishment.

Excellent service, reliable, fair, and a great quality of workmanship with an attention to detail - I would definitely recommend PJ Electrics London (I dealt with Sean the Ops Director & Ryan the Engineer)

Being a property manager for a local estate agent, that covers London and Surrey, I am always in need of good contractors, and P J Electrics have never disappointed. They are reliable, efficient, and great at communicating all aspects of their work. I have had nothing but positive feedback from both our landlords and tenants. Kevin has been great to deal with, and I now wont use any other electricians for all our rental properties.

I called Sean from PJ electrics recently and he was polite and courteous and offered to provide a free quote. Ryan came along and confirmed the job. Ryan and John were prompt, polite and respectful - I even handed them the keys so they could let themselves in/out. The work was speedy, done to an excellent standard and they left my shed spotless! I am 100% pleased with this work - you should try this company - they have “good old-fashioned” values (well mannered, great work ethic and polite) you won’t be disappointed!

Lloyd and his team did an absolutely fantastic job at our property. The booking system is extremely easy to use and you have full transparency on who is coming to do the work and how they are getting on with the journey. Communication with Lloyd was excellent throughout. He was very quick with responses at all hours of the day (including weekends) and always went out of his way to provide very detailed explanations of what kind of work needed to be done, why they were recommending it be done a certain way, etc. He gained our trust from the very first interaction and we were never disappointed. In terms of the actual work carried out, we first had an EIRC done which highlighted a lot of remedial work required, as the property we recently bought had been somewhat neglected in that respect. We discussed the results with Lloyd and got a very fair and practical recommendation on which items were important vs nice to have. In the end we decided to take him up on most of the work and that required multiple visits, but all was carried out seamlessly. The finished work is to a very high standard and we are overall very happy and would wholeheartedly recommend Lloyd and his team.

I needed an electrical timer on an immersion heater uograded, and a switch elsewhere replaced. I was on a tight deadline and they went out of their way to help me get it resolved in time. Communication was great from start to finish, Alfred who came to complete the work was very friendly, polite and helpful. I would not hesitate to recommend this company and will use them again in future.

Fantastic experience from start to finish - Lloyd was very communicative, patient and helpful in explaining my various options, which I was grateful for. Works (carried out by Nathan) were done to a high standard. Thoroughly recommend, I wouldn't hesitate to use Lloyd Hallowell electrics again!

Lloyd is probably the most professional, empathetic and thorough tradesman I have ever dealt with. His work and that of his team is consistently first class (I have used the company of a few occasions), his availability is extremely reasonable and he is always available to talk to on the phone. In addition, when my tenants had no power, he was on the phone sending videos and instructions to them at midnight and they were able to fix the problem in 10 minutes. Bravo, what a sensational business you run. I give at least 6 stars for Lloyd Hallowell Electrics!

I cannot praise the TNS team enough for their work on my project. They did an outstanding job on the full electrical rewire of our house, and the entire team was incredibly kind, knowledgeable, and helpful, with excellent communication throughout. Moreover, they noticed my struggles with other aspects of the house renovation and went above and beyond, connecting me with reliable tradesmen to help fix and improve jobs that were badly done by others. I'll always be grateful for their efforts and will definitely use their services in my future projects.

An absolutely exceptional service. A big thank you to Farhan, Afrim, Florian and Karim. You were polite, professional and explained everything, your work was amazing. I can't recommend this company enough. I will certainly be using them again.

Excellent Commercial electrician. They have identified our electrical fault within 15 minutes although we do have a very complex and modern heating system combining signals from Daikon and Crestron. We are strongly recommending the engineer called Nasser, who has an expertise with hearing interchange units (HIU) and an advanced heating technology.

I had a small job that only required an electrician for one hour. Although not everyone is happy to accept small jobs like this, MK Electrical booked me in straight away. They were on time, courteous, tidy and got the job done perfectly! Would definitely recommend - and would definitely use myself again!

Great service. Quick response to a technical issue with our wireless lighting system. All was resolved under warranty with no fuss. I am very pleased with MK Electrical London and am happy to recommend.

I live abroad and let out my flat. MK Electrical have never failed to promptly solve every problem my tenants have reported with minimal fuss. Continually great service.

A very professional company. Excellent service. Courteous and considerate professionals and service team. I felt very confident with the extensive electrical repairs and improvements they recommended to update wiring, plugs, fuse box and a number of things to improve the supply and usage. I would strongly recommend.

Installed electrics for our loft conversion and a kitchen refit. Henry was very punctual, friendly and efficient. Would definitely recommend!

Henry was super responsive, arrived on time and did a great job in installing my chandelier and other lighting fixtures. Will certainly call him again!

Called up with a minor electrical issue. Could easily have come out and charged me for a problem I could have sorted myself, but gave helpful advice over the phone that allowed me to fix the issue. Top guy!

Henry was brilliant in helping me with electrical problems in my flat. He went above and beyond to find the problem, fix it, and came back multiple times to ensure that it was working as intended. Highly recommend.

I highly recommend SES for any electrical work! Byron and the team are super experienced and trustworthy. It's definitely worth it to have someone do the job right. They were neat, tidy, and really friendly throughout the whole process. I can't fault them at all - great service and a pleasure to work with!

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.

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!

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!

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 called ‘Emergency Electrician London’ after a failed Smart Meter installation by our energy company (sub-contracted out to Magnum Utilities) left us with no power in the house at all. I got an answering machine initially but didn’t leave a message as I thought I’d just try another company. However, Cyril called back within 2 mins. and agreed to pop around within 90 mins. He arrived after about 60 mins. and got to work straight away and managed to find the issue after about 10 mins (a disconnected wire). He explained to me exactly what had happened and got the power back on within another 5 mins. and then he proceeded to check all the other connections to ensure they were tight - some were very loose. All in all he was very professional, on time and he clearly knew what he was doing. Overall I’m very happy with his service and thankful for his quick response and fix.

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.

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

Rang for a short notice appointment and was very lucky. Knowledgable and polite Shamim came along assessed the problem and fixed it with no fuss bother or mess Would definitely give a recommendation to use this company

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

Very efficient, professional and knowledgable. Shamim got here as fast as he could despite difficult circumstances!

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 have called on Certified Electricians London Ltd three times now and I couldn't be more impressed with the service! From the moment I contacted them, the communication was prompt, professional, and clear. After sending photos or short videos via text message or WhatsApp to help diagnose my issues, they scheduled an appointment quickly and arrived on time on each occasion. I saw their van on my way to work one morning and took a photo of their contact details painted on the side. What fortunate serendipity that has proved to be! Marlowe, my electrician on all three occasions, was incredibly knowledgeable, thorough and efficient, quickly diagnosing and resolving the electrical issue I had on the first two occasions. He took the time to explain what was happening and offered helpful advice on how to prevent future problems. On the third occasion he fitted outdoor sockets and fitted a new ceiling light. All the work was completed to a high standard, and he made sure everything was in perfect working order before leaving. On top of the technical skills, I really appreciated how friendly, respectful, and tidy he was throughout the process. It's not every day that you encounter such great customer service alongside top-notch workmanship. I highly recommend David’s team at Certified Electricians London Ltd for any electrical needs and will definitely be calling them for future projects.

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.

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!

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.
