David and the team were so helpful they made the project a breeze. I needed new track lights put up in a tricky space. Marlowe, the engineer who came to do the work, was punctual, friendly and did an amazing job – leaving no dust at all! I would definitely recommend them.

David and his team at Certified Electricians London Ltd were fantastic from start to finish. They recently carried out a full installation of a new 3-phase consumer unit and oven circuit at our unit, and I couldn’t be happier with the service. They were professional, friendly, and really took the time to make sure everything was done properly and safely. David clearly knows his stuff and made the whole process easy and stress-free. It’s a relief to have such reliable and skilled electricians – I’d definitely use them again and highly recommend them to others!

Had a great experience working with David / Luke to install some lights at my home. I had many questions initially but David was able to answer all them with patience, which made me feel at ease. Luke did a fantastic job installing the ceiling light. When the light turned out to be faulty, they offered to help install the replacement at a lower fee, which was a nice gesture.

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! Natalia & David P

Great! Persistent and logical with a fault with our lounge light, had the necessary parts on the van and in and out in less than an hour. Friendly engineer happy to chat about the steps he was trying, clean and tidy and I was comfortable having him in my home while home alone. Very happy, would use again. Thanks David & team.
