SES Water (Sutton and East Surrey Water) says complaints should be sent for the attention of its Customer Relations team, quoting a customer reference number if there is an account, and that a fuller procedure is in its Making a Complaint fact sheet. If unresolved, it says customers can go to the Consumer Council for Water and then to the Water Redress Scheme (WATRS). - If it is not resolved
- Consumer Council for Water (CCW)
- When you can escalate
- CCW says you can contact it once you have a final response (letter or verbal confirmation) from the water company or have waited eight weeks.

- 4 October 2026 (company pages and scheme websites). Rules and pages change, so check the official page before you rely on this.
Good to know: SES Water handles water complaints only; sewerage issues go to Thames Water or Southern Water depending on location.
What to Do, Step by Step
- Gather your evidence. Order or account number, dates, receipts, screenshots, emails and what was said on calls.
- Complain in writing using the route above, and ask for a complaint reference. Say what went wrong, what you want, and by when (14 days is reasonable). Our free letter templates can write it for you.
- Keep a record. Note dates, names and reference numbers of every contact. Use email or a form where you can, so you have proof.
- Ask for a final response if you are not getting anywhere, then follow the escalation route above.
- Use other routes if they apply. If the company does not fix it, take it to the free ombudsman or ADR scheme named above. Your bank or card provider may help if you paid by card (Section 75 or chargeback). The Citizens Advice consumer service gives free advice and can pass a report to Trading Standards.
