Today was when Mark Coulstock fitted a new hot water pump. He had been previously to quote. Both times he was punctual, smart, friendly and polite. He is competent and a fast worker. He is also well organised and I have booked him again to do more work.

Mark fitted a pump to upgrade an existing shower & fitted a separate new electric shower. He also resolved a couple of more minor plumbing issues. He gave a very competitive quote, was punctual, reliable & we were really impressed by the quality of his work. We will definitely use him again.

An incredibly professional job. Mark turned an aging and difficult bathroom into a superbly finished room. I have to applaud his shill and professionalism. I would recommend him very highly.

We chose Mark because he is an accredited Worcester Bosch Installer and quoted us a fair price for the job. We are very satisfied with the neat and tidy way he installed our Greenstar 30CDI System Boiler. He was also most accommodating regarding the position and location of pipe runs and cleaned up well afterwards. We would have no hesitation in recommending him.

I only needed a couple of small jobs doing. They arrived promptly, assesed the work and discussed options. They carried out the work efficiently and well. I recommend, and will certainly use them again. Good experience of Trusted Traders.

Mark responded very quickly to our original call. We assumed because the job was small and fiddly (leaky toilet, removal of radiation) that we would be back of the queue. Instead the job was done and done very well - only two days later.

Mark listened to my ideas regarding our traditional bathroom and made some alternative suggestions to what I initially had in mind, and we are so glad that he did. He was the first, and only, tradesman to highlight potential problems with our initial plan, his suggestions not only saved us money but future problems with the bathroom. He is honest, trustworthy and reliable; he arrived promptly everyday and finished the job on time, within the budget. The bathroom looks fantastic and has been completed to a really high standard. He was friendly and helpful throughout the whole process (and as far as building work goes, the house remained quite tidy!) Love our new bathroom, fantastic service and finish; we couldn't be happier!

Mark was professional, reliable and on time every day. He fitted us a new combi boiler and radiators throughout. He explained everything fully. I didn’t worry about having him my home. He was tidy and even helped us remove the old system when we were struggling to do it. Would recommend to friends and family. Will use again for other things. Extremely happy with the service

Mark replaced a full en-suite bathroom, installed a new boiler and cylinder and replaced a number of radiators throughout the house whilst installing Hive. All work was done to a really high standard and was very reasonable. Mark was very personable and continually kept the house clean whilst he was working.

Mark solved a challenging access problem to fix my waste pipe leak, returning my kitchen to me and upgrading my bathroom with a new loo into the bargain. Great result, kept me advised and in the picture throughout, and charged as per the quote. Worked hard, turned up on time and did what he said he would. Excellent in my book. Wouldn’t hesitate to use again or to recommend.

Mark was professional reliable and friendly. The work carried out was the fitting of a new boiler, radiators throughout, a timer unit, replaced two toilets and fitted bathroom flooring. The work was carried out to a very high standard, finished on schedule and within the reasonable budget. Mark kept me informed throughout on progress of the work and was very approachable. I would highly recommend Mark and will be using him for any future work.

Mark Coulstock of MJC Plumbing & Heating has been my plumber of choice for the past fifteen years. In all that time, he has always been totally trustworthy and reliable. His work has been first class, top quality and completed in good time. He is a highly skilled tradesman who takes great pride in his work. Mark is easy to contact and easy to talk to. He takes time to listen to what you want, offers solutions to problems, explains what the work will involve and gets the job done all at a fair price. Most recently, Mark installed a replacement combi boiler in an outside utility room for me, installed a low level WC and wash basin along with appropriate plumbing for a washing machine. He sourced all of the sanitary ware, planned the pipework to perfection and following his recommendation, lagged all the exposed pipework. All of this work was completed within three days, Mark is an excellent timekeeper. Mark removed all the packaging and waste materials and left the utility room clean and tidy. When all the work was completed he explained clearly how the new boiler and thermostat controls operated and set them up for me to my preference. I am delighted with the work he has done for me and have no hesitation in recommending him to others.

Mark arrived on time, explained the process for the removal of the existing central heating boiler and the installation of the replacement. I was made aware of any problems as they arose, and the proposed solutions. Mark was competent throughout, and the finished work was first class. The area was cleaned after the work was completed, and an explanation of the working of the new boiler was clearly explained. Everything was completed within the agreed timescale and budget. I have found Mark to be extremely helpful and professional in all my dealings with him, and would thoroughly recommend him.
