If we've made any changes to a bill that has already been sent to you, you'll receive an Advice of Adjustment notice. You don't need to pay this. It's only for your information.

Here's an example of an Advice of Adjustment notice:

This can relate to:

  • Leak allowances
  • Land use – if a new house has been built or an old house has been demolished.
  • Classification – if a house has been converted into a doctor’s surgery
  • Service availability – if a sewer main has been extended and your property can now be connected to the main wastewater system.
  • We overcharged or undercharged you by mistake.
  • We have reversed charges on your account.
  • We have applied or removed a concession.

The Advice of Adjustment will let you know of any additional charges or credit adjustments as well as your new account balance.
