Customer Reviews
Genuine reviews from verified customers across Leeds and West Yorkshire.
West Yorkshire · October 2025“We've been using Mark and Sam for 18 months. Whether a boiler service, repair or new installation of our hot water cylinder, the work has always been excellent. There's never delays, the work is exemplary, and when we needed a repair Sam came the same day. Both Mark and Sam are brilliant to deal with - friendly and professional. I can't recommend them highly enough.”
Sally Gutteridge · November 2025“Fantastic service highly recommended! Reached out to me directly after posting a job on MyBuilder and my local community group, very impressed with the effort, efficiency and a job well done. Had my shower replaced after it had become quite tired, and the new one is great! Sam even adjusted the water pressure in the house as he said it was low. Would definitely use them again thank you!”
West Yorkshire · October 2025“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. The quality of his work was excellent and his professionalism and attention to detail really stood out. We'd highly recommend Mark Thompson Ltd.”
Phil · January 2026“We recently had our boiler replaced and relocated, and once again the service from Mark Thompson and his team was outstanding. We’ve been using Mark for around 20 years now, and the level of professionalism, reliability, and courtesy has never wavered. This time, Harry carried out the installation, and he was an absolute credit to the team - polite, dedicated, and incredibly tidy. Each day the workspace was left spotless, and the quality of the workmanship was fantastic. The job was completed neatly, efficiently, and with real attention to detail. Highly recommended.”
West Yorkshire · September 2025“We've been putting off replacing our 25-year-old boiler for years, always concerned about who to trust. From the moment I contacted Mark, he was fantastic - always replied to queries incredibly quickly, came on time to give a quote, and the price he quoted was the price we paid. No nasty surprises. Harry and Rio worked tirelessly to site the new boiler. We've finally found a company we will definitely use from now on and will be recommending to family and friends.”
Marcel Manners · November 2025“Harry recently fitted a new boiler for me and I couldn’t be happier with the service. From start to finish, he was professional, punctual, worked efficiently, and left the area spotless once the job was done. The boiler is working perfectly, and I feel confident knowing it was installed by someone so skilled and trustworthy. I wouldn’t hesitate to recommend this company to anyone in need of a reliable plumber. Top-notch work!”
