HRM 25/19 oil combi boiler

Our boiler stopped and Clark replaced the expansion vessel on 14th June. However, he then discovered that the braided link hose was leaking. He returned and fitted a new part on 19th June. The boiler then started but only worked on central heating as the diverter valve was sticking. Clark knew that we needed hot water to shower and he returned (20 miles each way) with the part when we were available at 6.30pm the following night. Our boiler is now functioning properly again. He did this politely, understood our boiler’s parts well and worked efficiently at a reasonable cost.

My father's heating broke down and after the boiler manufacturer sent an engineer it was clear that the issue was not with the boiler but with an external pump which wasn't covered by the boiler warranty. I looked at Which Trusted Reviews and decided to give Assured Heating a call. Clark phoned me straight back and I explained what the issue was. He gave me an estimate of the cost and we agreed that he would come to my Father's house on Monday 01 April at 9.00 He turned up bang on time, completed the job quickly, charged me exactly what the estimate was and was really friendly throughout the visit. I know that it can sometimes be difficult to reliable people but for me this was a job that was really well done by a pro. I've kept Clark's number in my phone and would not hesitate to call him again in the future. Thanks Kenneth Park

I had new central heating boiler and radiators fitted by Clark and his young apprentice on 24 January 2017. Chose Assured Heating because of favourable reviews on Which? Recommended Traders. Could not be happier with standard of work and service. I received estimate on the same night that Clark called to view the job. Price was competitive and fair. I spoke to Clark on two or three occasions before he did the job. He contacted me when he said that he would. He appeared on time and completed the job in one day. Very good, clean worker. I would strongly recommend this trader. Ian (Carluke)

Clark came out on Hogmanay to look at boiler which had packed in 4 days previously. He knew exactly what was the problem and got it going. However he found that we needed another part to complete the job and very kindly came back out to us at 7pm on Hogmanay to fit the part! Can't recommend him enough, excellent work, very competitive prices and knows his job ! Boiler working better than its ever done! Thank you so much clark

This man is a genius - he diagnosed the problem with my daughters central heating boiler in minutes. After spending hundreds of pounds with a "local" plumber/heating engineer trying to sort the problem but failing, I decided to do more research for someone who had expertise in wet central heating systems. I found Clark of Assured Heating and called him. He surveyed my daughters flat two days later and installed a brand new boiler three days after that. In short, within a week he had sorted the problem at a very competitive price. My daughter said he was fantastic - even taking time to go over all the programs/settings with her. I cannot recommend him highly enough - he and his colleague were prompt, clean, tidy in fact all that you could wish for in a professional tradesperson. This service is 5* plus. Thanks Clark from Jen.

My friend recently moved into an all electric flat which had an appalling heating system (wet electric central heating and mains pressure hot water storage) which had been badly installed and was proving problematical. Clerk responded to her call for assistance and quickly assessed the options of repair or replacement. After patiently discussing the pros and cons of her options, and without any pressure from Clark, my friend opted to install a new electric combination boiler system (Thermaflow) to supply hot water and wet central heating on demand 24x7 but using Scottish Powers Economy 2000 tariff. The all in price quoted was extremely competitive and the job was carried out cleanly and efficiently on the date and time agreed. Clark's skill and knowledge are the best I have ever experience. I was personally present during the time he carried out the work and would have no hesitation in recommending him. I have put him on my contact list for any heating needs I may have in future. The quality of work and price were both excellent and my friend is extremely pleased with the outcome. Although, technically, I wasn't the paying customer I was involved with the work from start to finish and my friend has fully endorsed this review.

Had a VERY satisfactory experience with Clark. He had to deal with a 20 + year old system. Work was done in two days by him and his apprentice with time to spare.Keen to help show how to work the new control system...which I needed ! Even came to my aid on Xmas day when my son and family ( from Thailand ) were finding it a bit cold for them ! Full of good humour and stories .Very professional. He called again after month to check how things were going. Have recommended him to a friend. He was much less than other quotes too.

I used Which Local to find Clark Pheely (Assured Heating) due to all the good reviews - they were spot on. The entire central heating system had to be replaced in the family home, but being overseas I needed both a reliable boiler and engineer. Clark chose the Worcester Bosch 38CDI for the job (good Which reviews). He was patient and friendly in answering all my questions, reliable and efficient in carrying out the job within the budget and time quoted, and very professional with his advice and choice of materials. Knowing how much I relied on reviews from Which members, I have left my comments for 8 months, and there have been no problems with the system in that time. I know I can rely on Clark to continue provide excellent service.
