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

I had a very pleasant experience with George and his service when having difficulty in installing an oven. After a failed EICR etc

The job was diagnosed and completed quickly. Thank you for the quick and efficient service. A++

George completed an EICR report for me and was brilliant. He kept me informed of his expected arrival time and was very polite and thorough in his checks to ensure the safety of the electrics. He was efficient and completed the check within 20-30 minutes. Arranging the appointment was really easy on the phone. Completing payment using the online link was quick and easy. Highly recommend this company.

The guys came when they said and were professional and good value . Thanks Dan

Great service! The team was professional, arrived on time, and completed the EICR efficiently. They handled everything quickly and at a fair price. I highly recommend them.

Fantastic experience! Very professional, on time, and got the job done efficiently. They installed my bathroom light quickly and at a reasonable price. Highly recommend their services.

We are a letting agent, we’ve been using Ilford Electricians Ltd just over a year, job is done prompt neatly & professionally, never let us down. Any urgent job is also taken seriously. Rashid

He replaced my fuse board and was very clear when explaining how the new one works, he felt the area he was working in very clean, a great guy i will use him again and recommend him to everyone

Aziz was the most experienced technician who visited my house to give me a quote to replace the fuse box and install an RCBO unit along with a cooker switch. He was the only one who noticed my house did not have water or gas electric bonding and explained the risks of not having that. While the job ended being a little bigger than the other quotes, it seemed to me other electricians were offering a lower service job and not really taking into account the whole electric system of the house, given that the works involved something so central as the fuse box . Aziz was also the only one to offered an electric certificate for the house, having tested it throughout. As for the price, his quote was around the same price as the other electricians that visited the house.

I've had two service appointments with these electricians and would highly recommend! They're easy to communicate with, arrive on schedule, polite and courteous when in my home. In addition, they repaired my bathroom fan and it is now working well.

We spent a month with no bathroom lights waiting for our estate agent who said they’d resolve the issue. We decided to find someone ourselves and contacted Aziz who fixed it in a day. Great service, fast and clearly very experienced.

Aziz is very friendly. He showed us how things work when we didn't know how to start them. He replaced two heaters in the apartment and I am very happy with the work he's done. Would recommend him to family and friends.

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.

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.

I am very pleased with the work. Absolutely great service, they responded spontaneously and were warm and friendly. Thank you very much again Jermaine & Ben you were absolutely fantastic! Really top class service. Highly recommend!

Highly recommended. Jeremain and Ben installed my Tesla charger and they really did a fantastic and very tidy job - which involved extending power supply from the fuse box to the front garden. They explained the whole process in detail beforehand and are very polite and professional.

I'm happy to convey my feedback for the services EVP Electrical Ltd provided which was to fit two new panel heaters. I found Robert (the electrician) to be both friendly and knowledgeable. He worked quickly and made sure he tidied up after himself. He tested the product before he left.

We contacted EVP Electrical for an EICR based on the online positive reviews and can confirm that they are indeed a very good choice. Jeremain and Ben were very professional, efficient and extremely thorough in their work with excellent attention to detail. They uncovered long-standing defects which they remedied promptly and returned a few days later to finish the job, fitting around our schedule and at no extra cost. The quote they provided initially was fair and there were no hidden or extra charges after they completed the work. They explained everything they were doing clearly and provided valuable advice going forward. We found them personable and trustworthy, and have no hesitation in recommending them to anyone who needs electrical work.

Outstanding service from Andrei and colleagues who installed a Joule unvented cylinder for me recently at very short notice. Very professional and skilled work carried out with real care and attention. Andrei also did some extra light installations. Highly recommend Andrei - nothing is too much trouble!

Beautifully installed boiler. Now every time I open the utility door I am happy. Absolutely beautiful. The team stayed till 2 AM in the morning to finish the work, it is unheard of in this country.

Really lovely experience dealing with Andrew , the installation was quick and efficient. We got the boiler in 2 days later after the one we had broke . Usually you would have to wait at least 7-14 days for a new boiler to be delivered. He even repainted for us ! Will definitely be using him again for anything we need and would highly recommend him to other people Thanks so much Andrew !!

I cannot recommend this service highly enough. 🌟🌟🌟🌟🌟 I had no water Saturday morning, and arranged a visit with Andre for Sunday in the 12-5 appointment window. I had a restaurant booking for 2pm Sunday I had forgotten about and when I called Andre to see if he can please come closer to 5 so I wouldn’t miss my outing, he went above and beyond for me!! He arrived within a few hours (late on a Saturday night,) checked my boiler out, and came back this (Sunday) morning at 8am with my new boiler. and a helping hand to have it installed. I write this with a new boiler installed about 24 hours after reporting the problem, on my way to my booking with no problems. Never has something that felt like a crisis gone so smoothly. Thank you SO much Andre!!!! He was also careful and considerate with my very curious cat and I really appreciate that as well. A friendly guy who does a great job. I will absolutely be recommending this service to anyone I can, and hope this review has helped you decide this is definitely the right company to call. 🤝

“Fantastic job by Will from OW London Electricians & Home Automation! Extremely pleased with the service—they are highly professional and offer great value for money. Would 100% recommend them!” I added before and after pictures

You never know the characteristics of the hired workers who will come to your door to perform jobs. I needed an electrician to install a ring doorbell, floodlight camera and chime. I was very fortunate to receive Will from OW Electric Limited. Johnny supported him, and they worked very well together, displaying the professionalism I like to see. They assessed the positioning of everything and involved me throughout this process, ensuring I was happy with the action plan. Their attention to detail was excellent. They ensured that wiring, etc., was neat and secure. Johnny made sure everything was connected to the app. They respected the property and went above and beyond to meet my request. I would happily invite them back into my home for new jobs. They have become my go-to electricians, and I highly recommend them. Thanks, guys!

Ow Electrical team Mike and Johny did a fantastic job in our home. There some issues from before we moved in and they solved it all in excellence. They even made all the connection safer. Our tube lights were missing mounting brackets they came up with a brilliant solution to safely fit all the lights. We highly recommend Ow Electrical.

The team added spot light to our living room, they worked efficiently, supplied all materials and cleaned up well after completion. Will be using for all our electrical work!!

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!

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!

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.
