As a member of BESA we are subject to regular third-party inspections and assessments, ensuring that our technical and commercial competencies continue to meet industry standards.


Heat Interface Units (HIUs) are an integral part of any district energy solution, providing heating and hot water to the residents. Unfortunately, not all HIUs are capable of efficient performance and the BESA 2018 HIU testing regime assesses key areas of performance and highlights how different HIUs will perform.

The pressure on the public and private sector to reach carbon targets is intense and we are seeing planning regulations and stipulations in tenders which ensure contractors maximise carbon reduction on projects. By insisting on a BESA tested HIU in the planning or tendering phases local authorities can have confidence that this part of the heat network will lead to maximum carbon savings.
