Worked for Hundreds of Satisfied Customers
Barney Woodbridge2025-07-24 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!) Monica Fyfe2025-06-23 Have used Diligent a handful of times now. Ishmael has always been professional, reliable and we feel reasonably priced. Highly recommend and we will continue to use! Tony Gough2025-06-21 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.
