I had the team come out to replace my consumer unit, fit new sockets and switches throughout my flat, and fit 3 new lights. It was a great experience from start to finish - David was really responsive and helpful over email before and after (when enquiring about further work) the guys were polite and friendly. They arrived exactly when they said they would and honestly didn't stop working. It was during the summer heatwave but they didn't complain and were also really conscientous of the flat the whole time, making sure to tidy up after themselves and checking everything was okay. When I noticed the apprentice had put one socket slightly off centre he quicky changed it (it was perfect now!) And then went round and double checked all the others to make sure they were okay. I'd really reccomend Certified Electricians for a trustworthy and professional service.

We used Certified Electricians London to move the consumer unit in my son’s flat and install a socket in the loft. The communication was excellent and the work was carried out on the appointed day. When my son arrived home from work he found that although the job was completed successfully the wiring in the loft was untidy and not secured in places. The company responded quickly and David came out the following day to check it and sort it with no quibbles. Super company with great customer service. We wouldn’t hesitate to use them again.

Ian and his apprentice carried out an EICR at my property and I was very happy with the service. They arrived on time, were polite, knowledgeable and professional throughout. They were also very respectful of my property, which is particularly important to me. They took the time to explain things clearly and I felt confident in the advice they gave me. I was so pleased with the service that I’ve asked them to provide a quote for some additional electrical work I’m planning. I would happily recommend them. Thank you again to Ian and his apprentice for doing such a great job.

I’m incredibly grateful that I came across this company through a Google search. From the very beginning, the communication has been outstanding, and the quality of work delivered by the team has been exceptional. I have now used their services twice, and on both occasions they exceeded my expectations. It is truly refreshing to find a company that combines professionalism, excellent communication, reliability, and high-quality work so seamlessly. There should definitely be more companies like this! I wouldn’t hesitate to recommend them to anyone looking for a trustworthy and professional service. Their contact details are safely saved in my diary for any future work. Thank you to the entire team for such a fantastic service!

We lost all lights in the house due to a hard to find electrical gremlin - technician spent the extra time to find out the exact issue and get everything repaired within an hour! Recommended & will use again.

Would highly recommend. They knew what they were doing and had the chops to back it up. A handful of Ethernet runs all perfectly terminated and tested, lights installed, low voltage speakers wiring and storage heater removal in a single day. They even made good of all the access holes they needed to make to run the Ethernet. If you want to hire a team that will be able to independently execute a plan and work around unknowns these are the guys.

Really happy with the work done, helpful and quick to book We dealt with David and Ian for our job, and had a great experience. David arranged the work to be done quickly (about a week) and Ian came and added a couple of new sockets for us and fixed a couple of broken ones. We're really happy with the work that was done. When the sockets were fitted, one of the cables seemed to come loose in our oven, and so it lost power later that day - but Ian came round the next day and fixed it for us. We got quotes from a few different electricians and the quote for this work was reasonable and in line with other quotes too.

Couldn't recommend Certified Electricians London Ltd enough. Calling late in the day, I was still able to get an appointment quickly the next day. Spoke to numerous team members whilst booking - all very helpful and patient. Joshua did a fantastic job - the company send you a notification when they are 20 or so minutes away so you aren't hanging around waiting long. Joshua installed a new heat alarm quickly and was so helpful answering any queries. All done in less than 15 minutes. Would highly recommend to anyone looking for a trustworthy, thorough and friendly electrician firm.

Trust professionals for your EICR Pleased with the level of quality and professionalism in conducting a required EICR for my flat. The amount of time spent ~1hr reflected the thoroughness required for this kind of electrical assessment.

Excellent service - LED lights and & Fan fitting I have used Certified Electricians twice now and they are highly recommended.  Joshua and Tyler attended and were professional and provided a speedy, excellent service.  Prior to the visit, I had a full quote, fully transparent, all explained clearly, no issues at all.

Excellent Company Certified Electricians were excellent. They arrived at the allotted time and carried out the necessary works in a timely manner. Thoroughly trustworthy and the quote was fair for the work carried out. Thoroughly recommend them and will definitely use again when required.  A 10/10 from me.

Reliable. professional and would recommend the company Excellent service throughout, they came and gave us some very valuable advice on our plans. From quoting to attending to carry out the work was timely and helped us leaving a tidy and clean work place. David and all his staff were professional and helpful during their time with us. They were recommended by a friend and I would do the same if anyone needed reliable electricians who live up to their name.

Excellent service from Certified Electricians. I'd attempted a minor electrical repair, got confused, and then remembered that calling in the professionals would have been the more sensible first step. Whilst not an urgent job, the team were there within a day and resolved the issue in about ten minutes. Perfect customer service and incredibly professional. I wholeheartedly recommend them.

I couldn't recommend Certified Electricians London highly enough! David and his team are great. We have been using their services for  years now for different types of electrical work, from new sockets, to a totally new electrical installation and fuse box for our Summerhouse to a new fire alarm system in the house. Definitely our electrician for life :-) They also provide certificates for the electrical installations which are usually required for Building Control, planning etc. They are super friendly, very knowledgeable, professional, approachable and totally reliable. Their prices are also reasonable, so don't bother searching for a different electrician any longer. Thank you team!

I can't recommend David at Certified Electricians highly enough! Superbly helpful, even checking the lights fittings I was planning to order and advising that they were suitable before I bought (for use in the bathroom). Responsive, polite, very helpful and efficient.  Will 💯 use again, and no hesitation in recommending them!!

The interaction with the company was very friendly and helpful, booking in an appointment within a reasonable time.  The engineer arrived on time and reminders were sent before the visit. The visit was carried out and the report clearly showed what issues needed to be resolved and a quote for the work was sent with the certificate.  Very happy with the responsive service and professionalism.

Highly recommended! Certified Electricians London came over initially to upgrade a fuse box for me. They did such a brilliant job that I keep finding other work for them to do. This has included fitting a very heavy and fiddly second-hand chandelier which they did really well. I had all of my sockets and switches changed over also. A new cooker hood and hob has also been fitted also. I have told all of my neighbours about their services as it is hard to find someone you can give a key to your home to knowing they will treat it with respect, do an outstanding job and tidy up before they leave. Turned up on time on each date they were booked. Expert service.
