Retailer-provided Royal Mail return vs your own postage

The first question is who arranged the return. If the retailer supplied a Royal Mail return label, QR code or Tracked Returns route, your first complaint should usually be to the retailer. You followed the retailer’s return process, so ask it to investigate the missing return and confirm your refund position.

If you paid Royal Mail directly, the claim route is different. Royal Mail’s compensation policy says a sender or recipient may claim for a lost item, but only one compensation payment will be made. Citizens Advice also notes that for Tracked 24 and Tracked 48, only the sender can claim compensation.

Use this test:

Ask: “Did the retailer supply the Royal Mail return route, or did I buy the postage myself?” That decides whether your first pressure should go to the retailer or Royal Mail.

How long before Royal Mail treats a return as lost?

Royal Mail says Tracked 24 aims for next working day and Tracked 48 / Tracked Returns aims for 2–3 working days. If a Tracked Returns item has not been delivered by the due date plus 7 working days, the sender might be able to claim compensation.

For 1st Class and 2nd Class services, Royal Mail’s loss policy generally says compensation for loss is not considered until 10 working days after the due date. For Special Delivery Guaranteed, the loss waiting point is 5 working days after the due date. Do not submit too early unless Royal Mail or the retailer has specific evidence that the return is lost.

First steps if your Royal Mail return is lost

  1. Find proof of posting. Use the Post Office receipt, certificate of posting, collection email, tracking receipt or retailer return confirmation.
  2. Save the tracking. Screenshot the Royal Mail tracking page showing the latest scan and date.
  3. Save the return label or QR code. This can show whether the retailer arranged the return route.
  4. Check the service used. Tracked Returns, Tracked 24/48, Signed For, Special Delivery and standard post have different rules.
  5. Message the retailer in writing. Give the order number, return authorisation, posting date and tracking evidence.
  6. Ask for a refund review. If you can prove you posted the return through the retailer’s route, ask the retailer not to treat courier loss as your fault.
  7. Escalate if refused. Use a complaint letter, chargeback or Section 75 if appropriate.

If the retailer supplied the Royal Mail label

If the retailer provided the Royal Mail label or QR code, your strongest argument is that you used the return route it supplied. Send proof of posting and tracking. Ask the retailer to check the return warehouse, open a Royal Mail investigation if needed, and confirm whether your refund will be released.

Do not accept “we have not received it” as the end of the discussion if you can show the parcel was handed to Royal Mail using the retailer’s route. The retailer may need to claim from Royal Mail, but your complaint is with the retailer about your refund.

Short wording for retailer-provided Royal Mail return

“I used the Royal Mail return label/QR code provided by you and posted the parcel on [date]. The tracking/reference is [tracking]. The return has not reached your warehouse, but I have attached proof of posting. Please investigate the Royal Mail return and confirm my refund position in writing.”

If you bought Royal Mail postage yourself

If you bought postage yourself, Royal Mail’s claim evidence rules matter more. Royal Mail says claims with intrinsic value should be supported by evidence of posting and evidence of value. Evidence of posting can include a certificate of posting, Horizon certificate of posting, Collect+ certificate of posting or collection email receipt.

Royal Mail’s retail compensation policy says claims for loss must be made within 80 calendar days of the posting date. Keep copies of anything you submit, especially if you send original documents.

What evidence should you keep?

EvidenceWhy it matters

If tracking says posted but no delivery scan

This usually means you can prove the return entered the Royal Mail network, but you cannot yet show the retailer received it. Screenshot the tracking and send it with proof of posting. Ask the retailer to investigate the return rather than simply withholding the refund.

If you bought postage yourself, use the same evidence in your Royal Mail claim once the relevant waiting period has passed.

If the retailer says “no refund until our warehouse receives it”

Push back politely. If the retailer gave you the return route and you can prove posting, ask it to investigate the Royal Mail return. A warehouse not scanning the return is not the same as you failing to return it.

Ask the retailer to confirm whether it supplied the label, whether it has checked the returns warehouse, whether Royal Mail tracking shows handover, and whether it will release the refund or provide a final refusal.

If you lost your proof of posting

Search your email and phone for Royal Mail, the retailer name, QR code, return label, tracking number, Post Office, collection and order number. If the retailer supplied a returns portal, log in and check whether it stores the tracking reference.

Without proof of posting, the case becomes much harder. Citizens Advice says proof of posting is needed to get compensation from Royal Mail. If the retailer supplied the return label, ask whether it can see evidence that the label was used.

If the item was expensive

For high-value returns, keep proof of value, photos, serial numbers, the label, posting evidence and return instructions. Royal Mail’s compensation for loss depends on service, evidence and limits. For ordinary retail services, compensation for actual loss is capped lower than Special Delivery; for Special Delivery, compensation depends on the compensation level purchased.

If an expensive return is going back to a retailer, check whether the retailer’s return label includes sufficient cover, and consider whether the retailer’s own process told you to use that label.

Common Royal Mail return parcel mistakes

Chargeback or Section 75 after a lost Royal Mail return

If the retailer refuses to refund after you can prove you posted the return using the retailer’s supplied Royal Mail route, chargeback may be worth considering if you paid by card. You will need evidence: order, return authorisation, proof of posting, tracking, retailer messages and final refusal.

Section 75 may be relevant for qualifying credit-card purchases where the item price was over £100 and not more than £30,000. Keep the seller, payment and return evidence clear.
