Where a premises has a single Rateable Value (RV), property drainage charges will continue to apply if rainwater from any part of that premises drains to our infrastructure.

Where business premises have multiple RVs, such as units in a retail park where each unit is rated individually, property drainage charges will only apply to those individually rated units that have a property drainage service.

A more detailed explanation, including effective from dates and caveats, can be found in the Property Drainage Policy Statement

The above determination also applies to premises which have been assigned a RV and a Council Tax banding (such as home based businesses), and future situations where the Assessor assigns multiple RVs to a premise that is currently covered by a single RV.
