An unexpected water bill can be as shocking as a gas or electricity bill — especially when it is based on estimated readings or a sudden jump in assessed charges. You have the right to challenge errors and request a refund.
This guide explains how to make a water bill complaint in England and Wales (Scotland and Northern Ireland have separate schemes).
Common Water Billing Problems
- Estimated bills that do not match your meter
- Sudden increase after a meter install or switch to measured charges
- Duplicate charges or wrong tariff
- Sewerage charges applied incorrectly
- Refusal to adjust after you submit readings
Step-by-Step: Water Bill Complaint
- Read your meter — photo with date visible.
- Compare to your bill — note the discrepancy in pounds and cubic metres.
- Complain to your water company — phone first if urgent, then email.
- Allow 8 weeks for their complaints procedure.
- Escalate to Consumer Council for Water (CCW) if unresolved.
| Problem | What to ask for |
|---|---|
| Overcharge from estimated reading | Corrected bill and refund |
| Meter fault suspected | Meter test and bill adjustment |
| Payment difficulty after correction | Affordable payment plan |
Keep a dated record of meter readings and every call — water companies often dispute timelines
What to Put in Your Complaint Letter
- Account number and property address
- Bill date and amount charged
- Your meter reading with date and photo
- The refund or correction you want
- Reference to estimated vs actual readings
- 14-day response deadline
A structured complaint letter speeds up billing complaints teams
Consumer Council for Water
If your complaint is not resolved within 8 weeks, or you receive a deadlock letter, CCW can investigate free of charge. They can require bill corrections and refunds.
Meter Not Read for Years?
If you have been on estimated bills, submit regular readings going forward. You can also request a meter test if you believe the meter is faulty.
