Estimated time: 20–30 minutesUpdated: 27 September 2026

Step by step

  1. Build a simple timeline

    Record purchase date, seller, item or service, price, payment method, delivery and the date the fault appeared. Keep receipts, order emails and photographs.

  2. Describe the fault precisely

    State what should happen, what actually happens and any safe troubleshooting already tried. Avoid opening or altering an unsafe product.

  3. Contact the seller

    Consumer rights usually sit with the retailer that sold the item. Use a traceable channel, quote the order number and keep copies.

  4. Ask for a clear remedy

    State what you want and a reasonable response date. The available remedy depends on what was bought, where, when and the circumstances, so check current official guidance.

Ready-to-use checklist

  • Purchase evidence saved
  • Fault photographed or recorded
  • Seller contacted in writing
  • Requested remedy stated
  • Response deadline recorded

Common problems

The seller sends you only to the manufacturer

Ask the retailer to address its responsibilities and confirm its position in writing. A warranty can add rights but does not replace statutory rights.

The issue involves unsafe goods or fraud

Stop using unsafe goods and use the relevant official reporting or advice route. Contact the payment provider promptly where appropriate.
