  Ishmael and Russel connected our garden room to the mains, with lighting, sockets, outside light and external power point. In the house they installed 4 additional sockets and a porch light, and replaced the bathroom light. They worked hard and completed everything in a day. I am confident that the work complies with the regulations. Their quote was very reasonable. Recommended, especially if you want work carried out promptly and efficiently.
