Heating & Plumbing Repairs


Generally boilers installed in large houses, offices, social clubs, schools, golf clubs and churches quite often require a single or multiple large boilers with outputs over 50kW’s. When it comes to installing commercial installations, careful consideration should be made for the future maintenance and repair of the system and its components. Working on large systems can be time consuming and costly, it is therefore important to ensure that necessary controls and isolation valves are installed to reduce maintenance time. This may add some additional costs to the installation job, but will save you money over the life of the installation. When we quote to carry out work, we will ensure the right controls and components are installed to increase fuel efficiency and minimise maintenance work.


Engineers who work on individual boilers or groups of boilers over 50kw’s require additional skills and qualifications in the commercial sector. We have engineers with the necessary skills and qualifications to work on these boilers.
