Cash referral bonus · Cashback
£10 bonus
New members get a £10 bonus after earning their first £10 of cashback through the site.
Opens TopCashback's site — the reward tracks automatically via this link.
TopCashback is the UK's biggest cashback site, and its referral scheme effectively pays you £10 for shopping you'd have done anyway. Join through a referral, earn £10 of cashback from any of the 6,000+ retailers on the platform — a single insurance renewal or broadband switch often clears that in one purchase — and the £10 bonus is added to your account. The site is free to use on its basic tier and cashback is passed to members at up to 100% of the commission TopCashback receives, which is why its rates usually edge out rivals. Payouts can be taken as bank transfer, or boosted by a few percent if you withdraw as gift cards.
