Charging based on current rateable values were introduced in April 2018. 

This replaced the historic rateable values previously used to calculate water and sewerage charges. 

From April 2020, all RV-based water and sewerage charges will be based on the same rateable value used to calculate business rates. 

Transitional arrangements apply from April 2018 to April 2020. This change will be revenue neutral for Scottish Water. 

To support the implementation of Live Rateable Values, we have produced two calculators that allow Licensed Providers to recalculate the charging glide path when there is a change to any of the charging parameters. These are available on the LP Customer Portal.
