I was very happy with the work Dave carried out. I’ve used Certified Electricians a few times now and they are my go to electricians.
Reliable, efficient, professional and reasonably priced too. Very happy with my electrical work. Would definitely use again and recommend too. Nice guys.
David and Jamie were true professionals - great work and efficient. Would recommend unreservedly.
Excellent service all round. David is the consummate professional.
David and Jamie fitted a new fuse box for me and wired some new sockets and spot lights. They were punctual, clean and tidy in their work, professional and polite. Their quote was fair and accurate with no hidden costs. Would highly recommend.
Strongly recommended; good communications.
David managed to fit us in for a consumer unit swap after a failed EIRC inspection turned up its non-compliance. He did the work bright and early on a weekend so we could meet our tenancy deadline - which saved our bacon. Work done to high standard and left the property exactly as he found it. Would recommend for any electrical work around the Canary Wharf area.
very helpful, punctual, goes era mile. Thank you Dave

Smart checks
Before you hire an electrician
In England and Wales, notifiable electrical work (new circuits, a consumer unit, anything in a bathroom or kitchen) must by law be signed off under Part P of the Building Regulations — confirm they will handle that.
Prefer an electrician registered with a government-approved competent-person scheme (NICEIC, NAPIT or ELECSA) so they can self-certify the work meets the wiring regulations.
Insist on the Electrical Installation Certificate (or Minor Works Certificate) when the job is done — it is your proof the work is safe and compliant, and you will need it if you ever sell.
Look for consistent reviews across several named sources, not one polished profile.
Check any verified credentials, and that the business details independently check out.
