  Chose Diligent Electricals because of excellent reviews. I was not disappointed. Ishmael came at short notice for a trip switch issue. Excellent service, very professional, friendly and informative. Will definitely use again.

  Have used DEC twice in the past couple of months - great service, communication and both jobs completely extremely quickly. Don’t need to look anywhere else for an electrician in the area (live around Gipsy Hill station!)

  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.
