New or Replacement Water Connection


Retail Market

The new Retail Market which opens on 1st April 2017 requires all water connections to Affinity Water Limited’s network to be registered with a retailer. Click here to find out more.



A new or replacement water supply is normally requested when:

  • New premises are being built on vacant land

  • An existing property is demolished and a new property or properties are being constructed

  • There is a need to replace old lead, galvanised and other metallic pipes

  • There is an increase in water usage, which requires a larger sized water connection

  • A property is on existing common supply and requires a separate supply

  • A property is divided into multiple properties
