How credit is calculated
The refund is calculated at 19.23% of water charges until the end of the 2005/06 financial year, and at 20.41% of water charges from the 2006/07 financial year onwards.
Interest is also added to the amount calculated. This is because this money has been held by us for several years.
Further information on the 2001 and 2006 water resale orders is available in the OFWAT guide to water resale.
