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.Posted on Google

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.Posted on Google
Grace McGowan5 September 2026Couldn'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.Posted on Google

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.Posted on Trustatrader

Natalia Hachy11 March 2025I 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!Posted on Facebook
Olive Oyl8 March 2025I can't recommend David at Certified Electricians highly enough!

Responsive, polite, very helpful and efficient. Will 💯 use again, and no hesitation in recommending them!!Posted on Trustatrader

Very happy with the responsive service and professionalism.Posted on Facebook
Verena Cornwall1 June 2024Highly 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.Posted on Facebook
