Letter Before Action for Utility Overbilling
By ClaimKit UK Editorial Team ยท Updated
Overbilling disputes often come from incorrect tariffs, estimated readings, or billing errors. A pre-action letter helps you set out the problem and the correction you want.
Set out your account and tariff
State your account number, tariff, and the period in dispute. Include any documentation that shows the agreed rates.
Explain the overbilling
Identify the charges you dispute and provide supporting evidence such as meter readings or usage records.
Request a correction or refund
Ask the supplier to correct the bill, refund the overpayment, and confirm the accurate balance.
Evidence checklist
- Recent bills showing the disputed charges
- Meter readings or usage records
- Tariff confirmation or contract
- Payment history or bank statements
- Emails or complaint references
Common mistakes to avoid
- Not stating the disputed billing period
- No meter readings or usage evidence
- Requesting a refund without a clear calculation
FAQs
Should I pay the undisputed amount?
Yes, pay the amount you agree with and state that you are disputing the remainder in writing.
What if the bill is based on estimates?
Provide accurate meter readings and request that the bill be recalculated using those readings.
Can I claim compensation?
Only if you can evidence a direct loss caused by the overbilling. Keep your claim specific.
