 TopCashback | £10 sign-up bonus |
Get a £10 sign-up bonus when you join TopCashback through a referral link, released once you have earned £10 of cashback on your own shopping.
A cashback site pays you a share of the commission a retailer gives it for sending you as a customer. You click through, buy at the retailer's normal price, and the money comes back afterwards, which makes it the one deals mechanism that works on purchases you were making regardless. TopCashback and Quidco are the two main UK sites and their per-retailer rates differ, so serious cashback users check both before a purchase of any size rather than picking one for good. TopCashback is the one I have used since June 2026, with confirmed cashback from Sainsbury's and John Lewis and refer-a-friend bonuses I have watched arrive, and its referral scheme pays a new member £10 once they have earned £10 of cashback of their own. One warning that applies to every page on the internet quoting these figures, including this one: TopCashback rewrites its refer-a-friend terms every fortnight, and the qualifying conditions move along with the amounts.
Best UK cashback site deals in 2026
Cashback sites do not run discount codes of their own, because they are not shops. The deal is the cashback rate at the retailer you are buying from, and those rates move between sites, so comparing TopCashback and Quidco on the specific retailer beats loyalty to either. On top of the rate, the sign-up saving is the refer-a-friend bonus: £10 to a new TopCashback member, released once they have earned £10 of cashback from their own purchases. Because that threshold is measured in cashback rather than spending, it takes an ordinary weekly shop or two to clear rather than a single click.

What are the best UK cashback site deals in 2026?
For cashback sites, the best deal is whichever site pays the higher rate at the retailer you are actually buying from, and that changes retailer by retailer, so it is worth comparing TopCashback and Quidco each time rather than committing to one. The sign-up saving on top is the refer-a-friend bonus: TopCashback pays a new member £10 once they have earned £10 of cashback from their own shopping. Neither site issues public discount or voucher codes of its own, since neither is a retailer.
