Incorrect Bill Dispute Letter

When to Use This Letter

Receiving an incorrect bill — whether from a utility provider, telecoms company, or other service — can be stressful, but you have the right to dispute any charge you believe is wrong. The Consumer Rights Act 2015 and sector-specific regulations (such as Ofgem rules for energy and Ofcom rules for telecoms) require suppliers to bill accurately and resolve disputes promptly. This letter formally disputes the charge and requests a corrected invoice.

What You'll Need

  • The company's name and billing address
  • Your account number or customer reference
  • The invoice or bill reference number and date
  • A description of the incorrect charge and the correct amount you believe is owed
  • Any previous correspondence or call references about the dispute
