We would prefer to speak to you to get your complaint resolved as quickly as possible - We're here to help between 8am-8pm, Monday to Friday and 8am-4pm on Saturday. If you have hearing or speech difficulties and use a textphone, please dial 18001 before dialing this number.

Stage 1: Complaint

We will do all we can to resolve your complaint over the telephone. However, if we are unable to contact you by telephone we will send you a written reply within 10 working days at the latest. When we reply you will be given the name of the person owning your complaint with a telephone number should you wish to contact them.

Stage 2: Complaint

If you’re not happy with our response, please give us a call as soon as possible on one of the phone numbers above so we can discuss the matter further. We want to do all we can to put things right. We will also escalate your complaint to an agent who has not been involved in your initial complaint who will carry out an independent review.

Stage 3: Consumer Council for Water

If you feel that your complaint is not resolved following Stage 1 and 2, you can refer your complaint to the Consumer Council for Water (CCW), the independent body that represents customer interests. You can also ask them to investigate your complaint if it's not resolved within 8 weeks.

Stage 4: Water Redress Scheme

If you remain dissatisfied following Stage 3, you may then be eligible to take your concerns to the Water Redress Scheme (WATRS) who will provide an independent binding decision. You will need notification from CCW before your complaint is eligible to be dealt with by WATRS.
