TopCashback - £21 Sign Up Bonus (Boosted)

Overview

TopCashback is the UK's highest-paying cashback site. Sign up via the 'Get This Offer' button and receive a boosted £21 bonus (normally £10) when you make qualifying cashback purchases — the boosted amount is available until 10am on 23 July 2026. It works similarly to Quidco and Rakuten, allowing you to earn money back on purchases you'd make anyway.

How to Claim

1. Sign up to TopCashback via the 'Get This Offer' button
2. Shop at any retailer through the TopCashback site or app
3. Click through to your chosen retailer and shop as normal
4. TopCashback tracks your purchase and awards cashback
5. Once you've reached the £10 threshold (typically within a few weeks, but you have 6 months), your £21 bonus is added — then cash out to your bank account (arrives in 1-2 days) or choose a gift card for a boosted amount
