Your rights

Under the Consumer Rights Act 2015, services, including billing, must be provided with reasonable care and skill. This means Severn Trent must bill you accurately. If they make an error, you are entitled to have it corrected and any overpayment refunded. If Severn Trent does not resolve your written complaint within 10 working days, you may be entitled to a Guaranteed Standards Scheme payment. If your complaint is not resolved to your satisfaction after eight weeks, or if you receive a 'deadlock letter', you can escalate it for free to the Consumer Council for Water (CCW).

Step by step

  1. 1Gather all relevant evidence, such as your bills, meter readings, bank statements showing payments, and any correspondence related to the error.
  2. 2Contact Severn Trent directly through their customer service line, online chat, or by sending a written complaint. Clearly state that you believe there's a billing error and provide information explaining why.
  3. 3Explain the error in detail, providing your evidence. Clearly request that your account be corrected and that any overpayment be refunded to you. Severn Trent aims to respond to written complaints within 10 working days.
  4. 4If Severn Trent does not resolve the issue to your satisfaction within eight weeks, or if they send you a 'deadlock letter', escalate your complaint to the Consumer Council for Water (CCW). CCW will usually ask Severn Trent to respond within 10 working days.

What they'll say, and your comeback

“It's an estimated bill, not an error.”

Comeback, My actual meter readings or usage history clearly show this estimate is significantly incorrect and has led to an overcharge.

“The error is due to a previous tenant or owner.”

Comeback, My contract is with me, and I am only responsible for my usage from [your start date]. Please adjust the bill accordingly.

“We've already applied a credit to your account.”

Comeback, I require a direct refund to my bank account, not a credit on future bills, as I have overpaid.
