“Just a line to express my appreciation for an excellent job with a special Thank-You to Lee, who was very helpful and is a very conscientious engineer.”



“Just a quick word to say thanks for a job well done.

You recently replaced the controls on my C/H system. The work was carried out promptly and for what I regard as a fair price.

The engineer was also helpful and pleasant. I will recommend you to others.

Thanks again”

“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.”



“After sifting through many local electrical companies to carry out our factory mains and lighting rewiring , decided to opt for John Clarke Services , i must say very pleased and impressed by level of service and thoroughness and good job done , nothing seemed like to much trouble and good bunch of guys , quoted job was carried out one day less that quoted for, which for once is nice , all certified and paperwork all arrived swiftly thereafter , would recommend.”


“Could you pass on my thanks to your team please for a job well done!”
