We have used John Clark Services for a number of years and found their service excellent. The communication and attention to detail on the high level project work carried out on our behalf is second to none. With friendly, polite and knowledgeable staff we look forward to working together on future projects.

Professional services company specializing in building services. I have no hesitation in recommending them as a one-stop shop for all electrical, access/automation system installation & maintenance and heating/plumbing. As experts working in Essex and the Home Counties they have a good reputation for fair pricing, conscientious crews and capable of a range of jobs small & large scale (complex). A trustworthy business to deal with.

Used JCS to rewire our factory and install lighting within the rear yard, we needed to ensure there would be no buisness interuption during the rewire and JCS gave full assurance that this would be the case, I am pleased to say that during the whole rewire there were no interuptions or issues whatsoever, the electricans work was well planned and the site left clean and tidy at the end of each day, the quote indicated the rewire would take 10 days to complete, the rewire was completed in 8 days, during the install there were a number of unforseen issues all of which JCS found solutions for, we also made a number of addititons to the original plan and again JCS had no issues I would recommend JCS without hesitation and have added JCS to our preferred contractors list
