I feel very reassured having had an electrical survey of my property. Their communication was excellent and timing perfect. The engineer was great, and was really helpful in answering all my daft questions. Thank you!
Certified Electricians carried out an electric safety check for me. As always the engineer arrived on time and completed the check quickly and efficiently. The company was very accommodating as I changed the appointment twice as tenants were unavailable. I would highly recommend Certified Electricians for all electrical work and a bonus is that they are a local company.
Ian provided an excellent service. He was professional, friendly, and very patient, taking the time to explain the issues and solutions clearly. The work was done efficiently and to a high standard. We are very satisfied and would happily recommend him to others.

Superb work carried out by the Ian and the team on several occasions - always arrived on time and completed all the jobs as required with the utmost professionalism. Very easy to arrange the appointments and excellent communication throughout the process from start to finish. Really friendly guys too - would highly recommend Certified Electricians to our friends and family. Thanks for all your brilliant help. Anita & David
Excellent service, very helpful electricians, we had a major fault and it was resolved. The main electrician also brought along an apprentice clearly learning in the trade, which was great to see. Bravo.
I have used Certified Electricians for my flat on a few occasions now & can honestly say I haven’t come across a more reliable & competent firm. David is an excellent knowledgable electrician & completely trustworthy & was able to help me out at short notice recently which I really appreciated. I thoroughly recommend CE !
Back in June this year, David and his team helped us out when we needed a couple of security lights (and switches) upgraded (previously jumbled with dimmer spotlights etc). Great communication – David identified the issue and found a solution. I suffer from anxiety. Nonetheless Ian arrived on time, was super professional, calm and courteous. The work was done to a high standard, he explained things and my concerns (and anxiety) were addressed. Very happy and would certainly use again
Andrew fixed the light switch problems quickly, and communication was excellent. Would definitely recommend.
I needed to replace an external PIR ight and have the cable checked and tested. I have used Certified Electricians London Ltd previously and have been happy with their work.
A well designed service with no hitches from start to finish. Good quality work, courteous workers and good value for money.
Used this business for installing a wired video doorbell. Was done to a high standard and with no fuss. Great to see there being an apprentice also learning on the job. Great communication also for quickly and easily being able to arrange a time and date for the work. Would very much recommend.
