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.

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

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.

Smart checks

Before you hire a builder

Never pay a large deposit up front — agree a staged payment schedule tied to completed milestones, and hold a small retention until snagging is done.
Get it in writing: an itemised quote with scope, materials, start and finish dates, and how any changes (variations) will be priced.
Be wary of a cash-only price or pressure to start tomorrow — both are red flags for an unaccountable job.
Ask to see a portfolio of completed work like yours, plus recent references you can contact.
Check the credentials and registrations that matter for this work — and that they are current.
