10 Helpful, timely and skilled. Did the job
Posted 27 May
Sanjay did a terrific job. He investigated what was wrong during his visit to give us a quote, which was very kind of him. He arrived at the appointed time and did everything he said he would do. Now our outside area is on it's own circuit, with it's own switch and we we able to use an existing consumer unit because of Sanjay's attention to detail and willingness to find the best and cheapest solution.Verified reviewerJob location: N14 10 Very good service and knowledge

Sanj was contacted to move a switch which was above my cooker location to the side wall to enable a safe installation of my cooker. Although it was Sunday, Sanj was punctual and made every attempt to find the colour I wanted (black) and made a good job. I will definitely recommend Sanj services.Verified reviewerJob location: UB10 10 Excellent quick support for electrical faults

Job location: W7Excellent work, our electrics kept short circuiting and we couldnt work out why. Sanjay came for an emergency call out, managed to isolate the issue and came back the next day in the morning to fix, very quickly. All complete within an hour 😊 very clear and helpful. Will be using again for sure.10 This is a very professional electrician and done a very good job at my home.

Sanj provided a very professional and efficient service in changing my bathroom lights. He recommended using the LED bathroom friendly spotlight. It also provided four different settings which was excellent because I didn’t want it to write. His price was good and overall was very happy with his work standard.Verified reviewerJob location: HA110 Electrical problems.

I highly recommend Sanjay, the electrician who helped resolve our intermittent electrical problems around the house. He came as soon as I made contact with him and with his expertise, he advised us correctly to resolve the problem. Very good service. Thank you. Hiten & family.Verified reviewerJob location: HA7
