  • All products displayed are eligible for cashback apart from HomeFi, free SIMs, top-ups for existing SIMs, upgrades, existing customer offers, accessories, and add-ons such as insurance.
  • To qualify for cashback, you need to complete your purchase on the same visit. If you exit from the Three website once you’ve clicked through and then come back another time, it won’t register, and you’ll miss out on the cashback.
  • From time to time information displayed here may be out of date. Please see TopCashback's full Terms and Conditions page for further information.

  • Should your cashback fail to track automatically, please submit a 'Missing Cashback' claim within 100 days of your order.
What to do when
  • The vast majority of transactions from merchants track successfully, occasionally a transaction may not get reported. If you believe this to be the case, please submit a "Missing Cashback" query no later than 120 days after purchase date. We will be unable review claims older than this.
  • Some merchants may not be forthcoming with untracked cashback. We endeavour to chase untracked cashback but reserve the right to halt enquiries at any time. Please do not make purchase decisions based upon expected cashback as it is not guaranteed.
