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 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.

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.

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.

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.
