A proper trusted trader!
Customer Service
Having had a few false starts/disasters in my search for an electrician To complete some external wiring and refitting of garden lights I turned to Trusted Trader and found Jamie and Steve, and what a revelation. I knew within a minute these guys knew their stuff, really professional and polite. The quote arrived very quickly and they fitted me in at short notice. Brandon turned up to do the work, and again he filled me with complete confidence, all works completed, no fuss, and a pleasure to deal,with. Invoice cheaper than quoted as he didn’t need to do all of the work!!! Amazing thank you guys. Already have them looking at some other jobs.

Electrical fault
Customer Service
Fantastic service. Very professional. All work completed on time and on budget. From first telephone call I was treated well and everything I was promised happened. Very polite throughout. Job completed in first class way. I thought the price quoted and delivered was amazing - extremely good value. I cannot speak highly enough of Steve and Jamie. If you need an electrician speak to theses guys - I shall certainly use them again if I have any electrical problem.

Inside and Outside Jobs
Customer Service
JS Electrical came to do various electrical jobs inside and outside. All the jobs were completed in a morning, Steve was very tidy, hoovering as he went. Would 100% recommend this company and will definitely be keeping there business card safe as its not always you come across a polite, reliable and efficient company like this one.

Great Customer Service
Customer Service
Jamie and Steve were brilliant. They sought to get some power back for me when I had a major failure. They arrived at the time they said and managed to isolate the fault and get most of my power up until they could come back to finalise the solution. They also spent a day installing a new fuse board and lights and power sockets in my kitchen. They are both courteous and have a great customer service ethic. They left my house clean and tidy and me feeling very confident about the work that they did. The price remained as quoted. I have no hesitation in recommending them. As a woman living on my own I felt very comfortable with them in the house. Very trustworthy.
