About us

With over 30+ years’ experience, we’re a highly knowledgeable team, committed to bringing energy saving solutions to companies across the UK.

Using Thermaflex technology, we enhance the efficiency of pre-insulated pipe networks, serving heating and cooling distribution systems.

From design, planning and installation, our engineers are involved in every step of the process to help create secure, low maintenance and energy efficient district heating networks.

At Flexenergy we continue to develop our products and now offer a unique pre-insulated valve system called V-Flex. V-Flex introduces new levels of valve control to district and community heating schemes, making network maintenance and extensions much easier to manage.

Headquartered in Glenrothes, Scotland, with projects spanning the length and breadth of the UK, Flexenergy offers unrivalled service and technical expertise, we have a UK wide network of Sales Engineers that offer support and knowledge locally to Consulting Engineers, Contractors and Project Managers.
