5.0

Customers report that Cardwell Electrical London Ltd carries out tasks ranging from minor socket repairs and fault finding to full rewires, consumer unit upgrades, and EICR inspections. Most reviewers praise the business for clear communication, transparent pricing, tidy work, and supplying official compliance certificates. However, one customer noted an incomplete oven repair where parts were left unassembled and loose screws fell out.

I had a really good experience with Cardwell Electrical London. The team was friendly, professional and easy to communicate with. They took the time to explain everything clearly and made sure the work was completed to a good standard. Everything went smoothly, and the service was reliable. I would happily recommend them to anyone looking for a good electrician in London.

I originally found Jasper through Google reviews and he’s totally lived up to his 5-stars! We’ve called him out numerous times for different jobs and he’s always been super efficient, professional, knowledgeable and friendly. We feel really lucky to have a local, trustworthy electrician to call when something needs doing!

Jasper fitted 10 smoke alarms in our house, alongside a new box and various works that he recommended doing. He did it with absolute professionalism, cleanliness and was a pleasure to have around the house. Thanks Jasper ⚡️

Reliable and expert local electrician, I highly recommend. I was in need of an electrician in the SE London/Brockley area, to help with an array of issues throughout a propery we had just moved into. After being let down by another electrician, I found that Cardwell Electrical provided excellent and prompt communication, explained issues and provided options for resolving them, and always turned up at the agreed date/time. Some quite substantial works in my home were undertaken, and were completed cleanly, efficiently and professionally. Prices were transparent, fair and explained in advance of work. We've been able to proceed with renovation work knowing that our electrics are in better condition and our home safer. (main works Cardwell Electrical completed for us: EICR, kitchen rewire and moving/installation of sockets, new consumer unit, installation of new bathroom extractor)
