Warranty Claim Letter

When to Use This Letter

When a product fails within its warranty period, the manufacturer or retailer is obliged to repair or replace it at no cost to you. Your rights under a manufacturer's warranty sit alongside — and do not replace — your statutory rights under the Consumer Rights Act 2015. This letter formally invokes your warranty, provides the required details, and requests the appropriate remedy within a reasonable timeframe.

What You'll Need

  • The manufacturer's or retailer's name and address
  • The product name, model number, and serial number
  • Your proof of purchase (receipt, invoice, or order confirmation)
  • The date of purchase and the warranty expiry date
  • A description of the fault and when it first appeared
