Your water bill has doubled overnight. Or you've been charged for a suspected leak. Here's how to challenge it, get a refund, and protect your rights.
Request a meter test from your water company to verify the reading is accurate. If you dispute the bill, write to your water company's complaints department explaining why. If they refuse to help or don't respond within 10 working days, escalate to CCWater (the water ombudsman). CCWater can order refunds and compensation up to £5,000 per complaint.
Meter Malfunction — Your meter may be faulty, recording water use that never occurred. Water companies must investigate on request and offer a meter test.
Leak Claims — Water companies often bill you for water lost through leaks inside your property, even if the leak is on the company's network. You have the right to challenge this and limit your liability.
Billing Errors — Estimated readings may be wildly inaccurate. You can request an actual meter reading and a correction.
Tariff Changes — Surprise price rises or new standing charges must be explained in writing and comply with your contract terms.
Water companies are heavily regulated. You have:
Step 1: Request a Meter Test — Call your water company's customer service line and request a meter test. Explain why you think the meter is faulty (bill spike, running meter in empty house, etc.). Most tests are free. Record your request date.
Step 2: Gather Evidence — Collect your last 12 months of bills, meter readings (if you have them), photos of the meter, and any correspondence with the company. Calculate your average monthly use before the spike.
Step 3: Formal Complaint Letter — Write to your water company's complaints department. Explain the issue, why you think the bill is wrong, and what you want (meter test, refund, correction, cap on leak charges). Keep a copy.
Step 4: Wait 10 Days for Response — Water companies have 10 working days to respond. They must acknowledge your complaint and investigate. If they refuse, ask for their reasons in writing.
Step 5: Escalate to CCWater (If Refused) — If the company refuses or doesn't respond within 10 days, escalate to CCWater (the water ombudsman). Visit ccwater.org.uk or call 0300 034 2222. Provide your complaint letter and the company's response.
If the meter is found to be faulty (undercharging or overcharging by more than 5%), the test is free and the company pays to replace it. If the meter is accurate, you may be charged for the test (typically £50-£100). Always ask about costs upfront before requesting a test.
It's risky. If you don't pay, the company can disconnect your water supply (though they must give notice first). Instead, pay the disputed portion or what you believe you owe, and dispute the excess. Document everything.
You may be liable for small internal leaks, but only if they were due to your negligence or failure to maintain the property. Leaks on the company's infrastructure (the water main, stop tap, etc.) are the company's responsibility. Challenge the claim and request evidence of where the leak occurred.
Up to £5,000 per complaint. This is compensation for trouble and inconvenience, in addition to any refund of overcharges. If your overcharge exceeds £5,000, CCWater can order the company to refund the full amount plus £5,000 compensation.
You should dispute within a reasonable time of receiving the bill (typically 2-4 weeks). For older bills, you can still complain if you discover an error. CCWater can order refunds for up to 6 years of overcharges in some cases.
