Sam and Mark were recommended to us by our builder to carry out both the first and second fix plumbing for our extension, which includes a new utility and shower room, as well as installing new radiators in multiple rooms. The first fix was completed efficiently, and the second fix will be finished later this month. So far, everything has been handled professionally — Sam has been reliable, communicative, and easy to work with, co-ordinating well with our builder and other trades people working on the project as needed. We’re really pleased with how things are progressing and would happily recommend Sam and Mark to others.

We had a fantastic experience with Sam for our boiler installation. From the start, he was extremely supportive and took the time to talk us through different options, especially as our house layout made things more complicated than usual. Sam was patient, knowledgeable, and helped us make the right decisions without ever rushing us. He offered up several solutions for fitting and positioning, explaining the pros and cons clearly so we felt confident in our choice. The quality of his work was excellent, and his professionalism and attention to detail really stood out. We’d highly recommend using Mark Thompson ltd to anyone looking for a reliable, helpful, and skilled boiler installer.

We needed a new boiler and Sam was able to sort it for us quickly. The boiler was installed with no fuss and Sam showed me how to use it. Everything was done to a high standard. We've used Mark before and will use again.

We wanted to change our 25 year old boiler . We've put it off year after year . Always concerned about who to trust to undertake the work . I looked on Which trusted traders in the hope of finding a company that was reliable. I also crossed checked with Worcester Bosch to get an accredited installer for their boilers . From the moment I contacted Mark , he was fantastic. He always replied to any queries incredibly quickly. He came round on time to give us a quote . The price he quoted was very competitive and it was the price we paid . No nasty surprises. He fitted in with the installation date that worked for us . Harry and Rio worked tirelessly, to site the new boiler in a different place . They were polite and really easy to get on with . Nothing was too much trouble and any questions we had were answered. We've finally found a company who we will definitely use from now on . We will also be fully recommending family and friends go to them for any work they need doing .

Had been having issues with the Combi boiler flame cutting out. Phoned this business based on reviews here. The boiler was not working, so as well as fixing asked for a full service. I was able to get an appointment very quickly. The engineer (Elliot) who turned up was professional and courteous. Left him to it. He had identified that the gas pressure was too low coming to the house, as well as two parts that were worn and needed replacing. He kept me informed as he was progressing work. He arranged for the Gas network engineer to visit to fix a pressure issue and did a full service. Excellent service and very reasonable rate. Will use again for sure and recommend to family and friends.

A superb service from start to finish. Mark surveyed the job and provided an excellent quote. Harry and Rio then fitted the new boiler within a day, taking extra care to protect our light grey carpet, and cleaning up afterwards. A polite, efficient and very competitive service. Highly recommended.

Mark and his amazing team took on the task on completely replumbing my very old heating system including removing and replacing an old oil tank in the back garden. The team of hard working specialists took ten days and did a fabulous job from attic to cellar. Their work is tidy and of a very high standard. We are very pleased with the work they completed for us.

Mark's son Sam just came and did our boiler service. He was friendly, polite and tidy as always. It's been five years since our ancient boiler broke down just before Christmas - Mark and his team swapped the boiler. A year later I had them re-plumb the whole heating system. They've serviced the boiler every year since. I trust them and am happy to recommend them.
