Simon attended to repair a serious leak above the dining room ceiling. Access proved to be quite difficult but Simon worked round the problem, identified the source of the leak and sorted everything out for us very professionally, keeping damage and mess to an absolute minimum and charging a very fair price for the work. This is the second time Simon has done work for us and I can't recommend him highly enough. A really nice guy and an honest and expert tradesman.

Simon installed a complete new heating system including boiler, radiators, uprated gas supply pipe and two new mains stop taps in a properly undergoing refurbishment. All pipe work is very neat considering the difficult working space the boiler was installed in and around a toilet. He is very concise in his work. He was very clean and tidy throughout the install and vacuumed before he left.

Simon and Finn were brilliant. From coming out to quote to final completion of the installation, turned up on time talked me through process. Tidy, polite, efficient. Can’t praise them enough for fitting me in so quickly as I had no heating and hot water even called me in the evening to check everything was running well. I will be definitely recommending him to my friends and family thank you very much Simon!

Simon arrived bang on time and was polite and personable throughout his visit . He assessed the problem right away and was able to fix it within a good timescale for me. When he’d finished he left the area he worked in as clean and tidy as he found it. I’d recommend Simon to friends and family and will be saving his details for any future plumbing needs I may have.

Simon came to do three plumbing jobs for me. He replaced the leaking waste outlet under the shower tray and resealed it. He then replaced the cartridge in the washbasin tap, and finally replaced a leaking non-return valve under the kitchen sink. I found him friendly, professional, efficient and reasonably priced, and would have no hesitation in recommending him for any plumbing work required.

Simon responded very quickly to my request for a bolier service, landlord check and installation of a room thermostat. His quote was very reasonable. He commenced the job soon after and completed it quickly and neatly.
I will use him again for my properties, such a find!
Thank you Simon

Simon came round after giving us a quote, he removed old radiator from one wall and supplied and fitted new radiator to a different wall at a affordable price, he respected our property although the dogs barking at him must of given headache. The quality of work and cleanliness was 100%, we have had previous work done by KCM and will continue to use for all our plumbing needs.
