Your company should offer you a variety of payment frequencies so that you can choose the one that suits you best. This will vary between the water companies. Typical examples include paying the bill in weekly, fortnightly or monthly instalments or in full at the beginning of the charging year.
Many companies will consider special arrangements at the request of individual customers. Your company will discuss a realistic payment plan with you to make sure that any instalment plan agreed is achievable and can be maintained.
You should also be offered a choice of payment method.
Your water company is also required to offer a range of locations where you can pay your bill.
Visit your water company website for further details on the payment options it can offer you.
