For all pipework which is the responsibility of the building owner or occupier leak detection is generally required between the building and the utilities water meter. This requirement is applicable regardless of the length of the pipework.
However, for campus type developments or those with multiple buildings on the same site served by common pipework, leak detection is required both within the building and externally for the length of pipework that exclusively serves that building.
Where it can be demonstrated that it is not physically possible for a meter to be installed on the pipework outside the building, the requirement for leak detection between the building and the utilities meter can be considered not applicable, and the credit awarded based on the leak detection within the building.
02 Jul 2024 - Updated to account for campus type developments. Applicability to UK NC V6 and INC V6 confirmed.
