Certified Electricians London Ltd

Excellent service from beginning to completion - all done within two weeks of first contact. The process was well organised and efficient, with good communication and formal confirmation at each step. Jamie and Marlowe, who carried out the work, were very professional and also a pleasure to deal with and have in my home. They took care with what they did and left everything pristine. I needed a number of items to be done, each individually small but collectively important to me. The results are just what I wanted at a very fair price. I recommend without reservation.

I recently had a hanging pendent ligts over the dining area.
Spoke with David over the phone and he suggested us to go with wireless switch for our hanging pendent light. This surely saved us from opening up the walls for sorting out wires.
On the day, Marlow came over to install the light and I'm very happy with the work he did. Very friendly and genuine guy.
Would definetly come back for future electrical works if needed.

Very happy with the service. David was prompt in correspondence and gave a very clear and reasonable quote. Marlowe fitted a new extractor and fixed the socket efficiently and at the time promised. We would use Certified Electricians again.

David was friendly, punctual and quick to replace my bathroom ceiling lights with an upgraded version that is more sustainable. His quote for labour and material was very reasonable. There were no hidden charges in the final invoice. I will definitely use this company in the future. Thank you David.

My step-daughter had two lights out caused by a short circuit. David responded promptly and agreed to call round within 2 days. The issue was quickly diagnosed and resolved within an hour. Very happy with the service and the price charged. Thank you so much.

These guys live up to their excellent reputation. Quick and easy to get a quote, David and Marlow both a pleasure to work with, very happy with my new radiators. Would come back again without a doubt for any other jobs in future.

Just want to say a massive thanks to David for the great work done at our home.
2 months ago we had a loss of power with a newborn who was just a few days old.
David solved the non-straightforward issue with some faulty wiring in the ceiling.
He also fixed some problems with the fuse box wired wrongly.
Finally, he explained interesting aspects about how the electricity is set up in the home extension with various options we have.
Everything has worked perfectly since.
All was done in a very professional and fast way. Thanks again.

David and Marlowe are the best electricians I’ve ever had. Here’s why:

They simply care: They replied to my emergency message immediately, even though it was late at night.

Extremely professional: I was slightly panicked when my old electric shower stopped working, fearing major issues like cable damage under the flooring. Here's what they did to solve the problem:
1. They diagnosed the issue, causing minimal damage to my bathroom furnishings.
2. Even though the root cause turned out to be the worst case—cable damage under the floor—they managed to fix it smartly by rewiring from the other side of the wall. This saved me tons of money by avoiding hiring a builder to redo the flooring, and fixed the problem without needing to worry about the old underfloor cable forever!

Highly efficient: The diagnosis and fix both happened within 2 hours.

Respectful: They cleaned up the mess left by the work as much as possible.

Fair and transparent pricing: David makes sure I know the price before the work is carried out. Very fair price comparatively. No hidden fees, no unwanted surprises.

Requested to install some sockets on our business premises. David & Jamie arrived on time. Work was done efficiently with no issues. Any mess was cleaned up before they left. Great work. Will use again!

Really happy with our visit from Certified Electricians. David was really easy to communicate with and set an appointment, Marlow did a fab job. Will use again and highly reccommend.

David communicated very well, was bang on time, and identified and fixed our electrical problem within a few hours. Thank you for a good job - we'll definitely use you again!

Very fast and professional service! David and Rob wired up down lights and an extra switch. They are now my “go to” electricians!

I had a great experience with David, I had him installing spotlights in my new flat and he did an outstanding job! Positive attitude, clear quote and really good prices - I had to book him twice to get an extra LED installed on the wall (again, the result was ace!). Can't thank him enough, David is a reliable specialist and I will definitely book him again when needed.

David was so helpful - amazing service, fixed multiple things in my flat at short notice - fitted a new radiator, fixed my dimmer switches and got my outdoor lights working again. I would recommend David to anyone.

David and Rob supplied and fitted downlights and completed other various pieces of work. They have a very good turn around time from my initial inquiry and were professional throughout. Would highly recommend.

We have been using David and his team for a few years now. They are always reliable, well priced, professional and kind! They are our go to electricians now and it’s for good reason. Thanks as always David, Marlowe and team!

David and his team have in the last few weeks repaired flood damage to a lighting circuit, conducted a full house survey, installed a new consumer unit and an EV charger. They've been brilliant: friendly, tidy, professional and competitive. Highly recommended.

Very happy to recommend this firm. I had an issue late at night and they were quick to respond and confirm an appointment for the next day. Marlowe and Jamie did a great job, were tidy and helpful in explaining what was done. Good overall customer service throughout

Marlowe and Jamie were lovely and got my lights back on quickly after a candlelit Christmas. Everyone I spoke to at Certified Electricians was kind and helpful and I would highly recommend.

Marlowe did excellent job of replacing my broken celling fan, installing a remote control and a switch. Certified Electricians is responsive and professional, reasonable price. Finally I found a reliable electricians company, it will be my go to now.
