Your SPID (Supply Point Identifier) number

A SPID number, or Supply Point Identifier, is a unique code that helps manage and bill water and sewerage services for farms in the UK. Each farm will have separate SPIDs for water and sewerage, found on your water bill as a ten-digit number followed by 'W' for water or 'S' for sewerage.

The exact location on your bill may vary by supplier, but if you can't find it, contact your water retailer with your supply address.
