The job was upgrading a circuit to 30 Amps, and installing an induction hob. James was able to identify what was needed over the phone and give us a quote. He showed up the next day and the job was done quickly, efficiently and tidily. I'd have no hesitation in calling him again.

We had a full rewire done I found SJConnolly team of work men very professional and the work being done to a very high standard. They were all, friendly, kind and considerate about being around the house doing the work which made it easy to be home whilst having work done. They cleaned at the end of each day and made sure things were all in order and put back furniture once the job had been completed. Very highly recommended

I would like to confirm that a wide range of Electrical works. Cabling ,fuse boxes ,loft work light additions and several sockets /switches were completed very much to our satisfaction at our new bungalow in Barkingside, Ilford by SG Connolly Electrical Every aspect was discussed uo front in a friendly cooperative way with James and they were extremely respectful of our live in needs over the 5-6 weeks. Their prices were most reasonable and they left each day with all areas sprightly cleaned up I would heartily recommend them to anyone seeking such residential electrical works in the months ahead.
