Rating: 5 / 5

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.

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!

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!

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.

Fantastic service and very competitive pricing. Jack and all his team have been amazing. Had an EV charger fitted and the guy who did it was excellent. Extremely careful and had unbelievable attention to detail as well as being an expert electrician. Would highly recommend this company.

Rating: 5 / 5

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!

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

Rating: 5 / 5

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

Rating: 5 / 5

Crispin was recommended by a friend who said that he was like a detective. I can confirm that assessment, and I'll add that he is reliable (he arrives when he says he will), reasonable, efficient, explains things very well, and is just a very nice person.

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.

Rating: 5 / 5

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.

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

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

Rating: 5 / 5

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.

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.

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!

Rating: 5 / 5

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.

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.

I used this group to install an outlet in my home. I recently found out it wasn’t grounded. I brought this to the attention of the owner. He, nor his technician took any accountability for the mix up.

I had a fantastic experience with Trish from Quantum Electricians & Plumbers. Her service was impeccable, and she was incredibly friendly and polite throughout our phone conversation. She patiently listened to my concerns and provided me with all the information I needed. Her professionalism and helpful attitude made dealing with our issues much easier. I highly recommend Trish and Quantum for anyone in need of plumbing services.

Rating: 5 / 5

Had a major electrical problem with my house alarm. I had amazingly prompt service. In this case it was Ben who was so helpful and experienced. Sorted it well within the hour and even voluntarily got my WiFi, which had nothing to do with the alarm, working again. He’s my hero. And I love the efficiency of the office, email confirming appointment etc..which I think was down to Trish. I can’t wait for my next emergency so that I can call them in again. (Okay, maybe that’s going a bit far…but I love them).

Called in the morning one day last week as something was triggering the fuse box. Billy was able to attend later in the day, he kept me up to date through the day with his ETA and when he arrived he was really friendly and chatty, found the fault and left us with working electricity. There was a part that needed changing, Billy again kept in contact and arranged to come back on Saturday morning to fit, turned up on time, tidied up after himself and explained everything clearly. Really happy with the service we recieved and felt the costs were reasonable and fair, especially considering a same day emergency appointment. Would definitely book Billy again if we needed any work doing.

Rating: 5 / 5

Used Quantum thrice now, for different plumbing and heating issues. Good quality of service and efficient with the use of time. For one of the issues the visit had to be rearranged at short notice due to the engineer becoming unavailable. The issue was not urgent though and given the overall experience I feel that 5 stars is deserved. Kudos to Charlie for the engineering work and to Trish for assisting with navigating through the visit rearrangement.

London Electricians Direct were very straightforward to deal with, by phone and email. They carried out an EICR inspection / report and then dealt with the remedial actions. Their site electrician - Sam - arrived on time and carried out his work with care.
