How To Pay

You can pay your bill in a number of different ways:

Direct Debit - Direct Debit is the simplest way to pay your water bill. It saves time, is more convenient and gives you greater control over your money. You are also protected by the Direct Debit Guarantee, which guarantees an immediate money back guarantee from your bank in the event of an error, provides you with advance notice if the date or amount changes, and gives you the right to cancel at any time.

If you wish to pay by Direct Debit (domestic customers only), then you can download an application form here. Alternatively, if you have any queries about paying by Direct Debit, then please contact us.
