Your invoice number is sometimes called your ‘bill number’. This is a unique number which identifies the particular bill that you’re looking at. We’ll ask for this number if you contact us with a specific query or issue relating to this bill.

You’ll have one or more Supply Point IDs, sometimes referred to as a SPIDs, listed on your bill – one for each water and/or waste water connection that you have. A SPID is the unique identifier for your connection to the water or waste water network and helps us to locate your premises.

Your fixed water charges are calculated using a set daily rate which is multiplied by the number of days in the billing period to provide the total charge. These charges cover the maintenance of external pipes and pumps that supply water to, and remove waste water from, your premises. The rate you’re charged is determined by your premises location (or water wholesaler region) and the size of your water connection – larger diameter pipes are charged at a higher rate.

Your yearly (annual) fee is listed on the left for your reference.
