Castle Water Complaints Procedure

Castle Water is committed to providing the highest level of customer care and this includes an effective process for handling complaints. Our complaints procedure has been created to make sure all complaints are fully investigated and satisfactorily resolved as quickly as possible. This document sets out how you can make a complaint, how Castle Water will handle it, and your right to appeal if you are not satisfied with our response.

If you wish to make a complaint, we will handle your complaint in line with the three stages of our complaints procedure.

Stage 1

If you wish to make a complaint, please contact us in one of the following ways:

(Telephone complaints will be handled immediately wherever possible.)

You can also raise your complaint using Resolver. You can use their simple online complaints form and we’ll work with them to resolve the issue.

Your complaint will be reviewed by our complaints team who will acknowledge your complaint by 6pm the following business day. We will investigate and may call you to discuss your complaint. We will provide a proposed resolution to the complaint or a substantive update on the progress of resolving the issue, as sometimes a resolution may require us to liaise with other organisations.

In responding, we will;

  • address all the points you raised in your complaint and provide a clear explanation;
  • apologise and explain what remedial action we have taken if we have fallen short;
  • consider whether we can offer compensation where remedial action is not possible or is insufficient.

If appropriate, we will place your account on hold while we investigate your complaint.

If the complaint has not been resolved to your satisfaction within 10 business days or you are dissatisfied with our response, then you may proceed to the next stage. Please note that if you do not reply to our response to your complaint within 30 days we may treat any appeal as a new complaint.

Stage 2

Following Stage 1, if the complaint has not been resolved to your satisfaction you can appeal the decision. If possible, please set out your appeal in writing and send it to us using the contact details above. This helps us to ensure that we have properly understood the details of your complaint and appeal. Your appeal will be considered by Castle Water’s Complaints Manager who will undertake an independent internal review and will aim to reach a resolution within 10 business days.

Stage 3

If you have completed Stages 1 and 2 of this procedure and are not satisfied with our response to your appeal, or if you have not received a satisfactory response from us within 10 business days, you can take the matter to an independent body who will consider your complaint and may investigate.

Please be aware that you may be referred back to us if you have not escalated your complaint via our formal complaints procedure outlined in Stages 1 and 2.
