Mark Knowles Heating has performed our annual maintenance for many years now, offering us a very high standard of service delivery each year. In December the company installed for us a new boiler and heating system - including thermostat, duct and vent, radiators and new location for the boiler. At all times, the company acted speedily, including an initial visit from Liam to appraise and quote for the job. They were always punctual and all team members were equally hard working and personable. We felt that at all times they did the best possible job for us, even if an alternative took longer

Liam and team installed a new system boiler together with a new tank and smart controls with a Nest system. Have to say this was a very neat and professional job. Two day install and Liam came back the day after installation to ensure that everything was working as efficiently as possible and took the time to go through the Nest system with me. Very happy with the product and the service received.

The plumber who called at my house was friendly, helpful and efficient, quickly sorting out the problem I had. I was so pleased with the service I have asked them back to repair other plumbing related issues. The lady on the telephone service was also very friendly and quickly made arrangements to have the plumbers call round. Very happy with this company and would recommend them and I am using them again.

Liam made a special visit to help out my elderly inlaws with a hot water problem. He was extremely helpful and very informative regarding what he was doing to try to rectify the problem. He made some progress on resolving the problem and then advised what action was required to resolve the problem permanantly. I would have no hesitation whatsoever in recommending this Company
