TopCashback vs Quidco: which should you join in 2026?
TopCashback and Quidco are the UK's two big cashback sites, they've both been around for well over a decade, and they both do the same thing: when you click through them to a retailer and buy something, the retailer pays them a commission, and they pass most of it back to you. Free to join, genuinely pays out, no catch beyond a bit of patience.
So which one? Here's the honest comparison.

Where they actually differ
- Rates. Both negotiate rates retailer by retailer, and both claim to be highest. In practice TopCashback edges it slightly more often, but the winner flips constantly — which is exactly why having both accounts and comparing for 30 seconds before a big purchase is the smart move.
- Retailer coverage. Heavily overlapping — thousands of retailers each. Occasionally one has an exclusive the other doesn't.
- Payout options. Both pay to your bank or PayPal, and both offer a boosted rate if you take payout as gift cards instead of cash.
- Premium tiers. Both run a paid tier (TopCashback Plus, Quidco Premium) with higher rates in exchange for a small fee taken from your cashback. Skip these until you know how much you'll actually use the site.
The one thing nobody tells you
Cashback is not guaranteed. It works by tracking your click through to the retailer, and tracking sometimes fails — ad blockers, switching devices mid-purchase, or opening a discount-code site in another tab are the usual culprits. Both sites have a claims process for missing cashback, and it usually works, but treat cashback as a bonus, never as a discount you're depending on.
Our verdict
Join both, via referrals so you get both bonuses — that's £30 for about twenty minutes of signing up, before you've bought anything. Then, before any purchase over £50, spend half a minute checking which site pays more that day. TopCashback tends to win slightly more often, so if you genuinely only want one app on your phone, make it that one.
