Been having trouble with my central heating for a while. Had numerous engineers out but unable to solve problems. Ajay and Jacob came out and worked seven hours and cured the problems to do with the wiring to the clock and controls. Brilliant job by a superb electrician.

Ajay did an outstanding job. He's full of advice and went above and beyond what I initially contracted him to do. Also very clean and tidy and wouldn't hesitate to call him back or recommend him to others.

I can recommend Aj highly enough. I needed a couple of jobs done quickly and he did exactly just that. Answered any queries I had promptly and clearly before the job started. He also rectified a bodge job that was done by the previous homeowner free of charge just to show how thorough he was. Any future jobs I will definitely give him a call directly.

Ajay did an excellent job fault finding the socket that was causing a shortage on the ground floor. He methodically went through all ground floor points of failure and was able to pinpoint the problem, which was a hidden fuse box that had gotten damp. He completed the works efficiently. Now I have access to laundry, dryer etc. Was quoted by another electrician extensive rewiring but Ajay came through and provided affordable and on time service without the need for rewiring, which was not required at all. I'm very happy and would not hesitate to recommend his services.

I used cosmos electrical when I was renovating an old house. AJ added additional sockets, switches, installed spotlights, fans, led lights and fixed alot of bad wiring from previous workmen. His knowledge in the field is exceptional and he is able to figure out out to resolve pretty much any tough situation. He is hardworking, on time and most Importantly honest. I came across him when seeking an electrician to install some led lighting in my living room. Many electricians avoided the job due to lack of understanding of the setup but Aj wasnt faded and accepted the challenge. He then went on to do many other jobs for me for which I was thoroughly satisfied. If your looking for an honest talented electrician then Aj is your man.
