On settlement of a property, your solicitor obtains a conveyancing certificate from us. This certificate states the charges that are outstanding on the property.
Your solicitor may make an adjustment based on average daily water usage and may deduct this figure from the purchase price of the property. The adjustment should be shown within the settlement letter that you receive from your solicitor. It is normally called the 'water usage adjustment'. The water usage charge will be shown as an outstanding amount on the next bill.
For any other amount on your bill, contact your solicitor for an explanation.
