I commissioned work from Duncan to replace ceiling lights in an area of my office. My staff who worked in that particular area wanted a specific type of lighting so as to reduce glare on their computer screens.
My staff in that are are now delighted that they can see their computer screens without glare on particulary sunny days. The whole process was professional from start to finish with no hitches, glitches or gremlins.
I would certainly recommend Duncan to anyone who is considering electrical works.
