When only part of the building is under assessment, there are two cases for achieving compliance with the requirement to specify a water meter on the mains water supply of the building:
If the whole building is under the same tenancy or ownership and management, then a meter monitoring the entire building is acceptable.
However, if the floors subject to assessment are separately tenanted, then a meter at the point of entry to the assessed areas is required.
Assessed areas have to be monitored separately for water consumption when only part of the building falls within the scope of assessment and where the assessed areas are separately tenanted.
