Our team handles everything from minor repairs to complete boiler replacements, using Grant boilers as standard but accommodating other brands when requested.

Our systems integrate with underfloor heating and radiators, offering sustainable solutions that lower fuel bills and carbon emissions. We apply anti-corrosion coatings for coastal properties and provide ongoing maintenance to ensure optimal performance and longevity.
Underfloor Heating
Our underfloor heating systems deliver efficient, space-saving warmth for residential and commercial properties. We design and install complete systems using top-quality components, incorporating heat sources like boilers or heat pumps. Each project includes precise heat loss calculations and tailored controls for room-by-room temperature management. Our installations prioritize energy efficiency, with potential savings of 15-50% compared to traditional systems, while maintaining aesthetic flexibility and comfort.

We handle all aspects of residential and commercial plumbing, from tap repairs to full system installations. Our services include burst pipe repairs, radiator replacements, unvented cylinder installations, and powerflushing. Accredited for Mixergy smart cylinders, we ensure modern solutions meet traditional reliability. Whether addressing emergencies or planned renovations, our engineers maintain high standards of cleanliness and disruption minimization during every job.

John and his team installed a central heating system and oil fired boiler into our 200 year old Millhouse which previously had only an Aga and stoves to warm it up - not an easy job with the very thick walls and 'interesting' architecture that had evolved over the years: Flowtech did a great job with a solution focused approach - nothing was too much trouble and we are delighted with the end result. Highly recommended.

John and Brad have just completed a new oil boiler installation for me. It is great to see two professional who are conscientious in everything about their work from quote through keeping me informed on when work would start and right through the installation itself. I will use them again and would recommend them.

I really cannot fault Flowtech at all. Before I found these guys I had tried other companies but none had been as reliable. John and Brad are professional, polite and always leave the place clean and tidy. I have also called them out in an emergency and they came immediately and fixed the problem.
