Extremely polite company to deal with, quick to respond and fixed the issue. Our electrician, Marlowe, was great. I'd absolutely use again when we next need an electrician. Thanks!

Booked Certified Electricians London to replace few LED lights, install new cabinet lights in the kitchen, and fit two new fire alarms. They (Marlowe) arrived on time, were very courteous and professional, and got the job done in a short period of time. They were happy to provide advice on parts and to source them themselves (Marlowe left and came back with the new lights/alarms an hour later to finish the job on the same day). I booked them two days later to replace a bathroom extraction fan which they did in under 1 hour. Again, I was very happy with their punctuality, quality of work, and level of service.

I've had a few jobs done by David and the team. Every time I have dealt with them they've been exceptional and always do a fantastic job. I really couldn't recommend them highly enough. I find they know their stuff and they are priced very reasonably. I will be using them again, for sure.

David came to install some wall light fittings and did a great job. Great service and expertise, top communication, and very reasonably priced. We will be calling them back for further electrical works at our place. Would recommend!

David runs a professional organisaiton. I needed some incorrectly wired low voltage towel heaters fixed. The prices were reasonable and he showed up on time and explained what he would do and solved the problem. Recommended.

Booked in David to install Nest thermostat. Very good comms leading up it. Turned up on time and was tidy with work completed. Had issue post work carried out due to Nest itself and older boiler and and David returned and fixed everything. Would definitely recommend and will be contacting myself again for future work.

Marlowe was a brilliant electrician - solved a problem that had baffled two previous electricians one of whom suggested we needed a total rewiring which would have cost thousands. This was not necessary. He was very courteous & professional. David was also very helpful on the phone beforehand when I explained what the issues were. I have absolute faith in this honest & experienced company & I would have no hesitation in recommending them to anyone. Thank you so much David & Marlowe !
