10 New Wiring for Oven
Posted 30 January
Job location: BR3Gary has done a fantastic job putting in some new wiring for our cooker. He was punctual, efficient and meticulous with his work. He was happy to explain everything that he was doing as well. I would 100% recommend him and I have actually already asked him if he is available for another job in my flat. If you want a job well done, definitely get in touch with Gary! - TTom S

Very happy with Gary’s work and would recommend. Gary has carried out a number of jobs for us including fitting new sockets, light switches and light fittings, and an outdoor light. Most recently, he converted two single plug sockets to double sockets, a job I was very happy with. Gary responds quickly to enquiries, is professional and delivers work to a high standard.Verified reviewerJob location: SW16 10 Great job, friendly and helpful. Would recommend.

Gary came on really short notice to identify and fix an electrical problem we were having. He's really nice and he fixed the fault. We needed a bathroom fan fitted as part of the job and, when we wanted one of the settings changed later, he was really helpful and came back to do it for us, which was much appreciated. Would definitely use SEC again and recommend them and Gary to others. A great electrician.Verified reviewerJob location: CR7- KKevin F

We hired Gary to fit some new plates to sockets and switches and install some new light fittings as well as reconnect an outdoor light. He sourced us some excellent plates to match our existing fittings and helped us over three visits sort issues with the various existing electrics and installed everything neatly. He is very fair with his pricing. He also took the time to explain any problems in easy to understand language for a non electrician.Verified reviewerJob location: SW1610 Excellect Work
