Best Cashback Sites UK

We compared four real UK cashback services on what actually matters: how many retailers they cover, what the welcome bonus really requires, how you get paid, and what you can honestly expect to earn. There are no affiliate or referral links on this page. Welcome bonuses change often, so every bonus below is dated — check the live offer before you sign up.

How cashback actually works

Cashback sites are middlemen. When you click from TopCashback or Quidco to a retailer and buy something, the retailer pays the cashback site a commission for sending you there. The site keeps a slice (or, in TopCashback’s case on its free Classic membership, passes on 100% of the commission it receives) and pays the rest to you as cashback. You pay the same price as anyone else — the retailer funds the cashback out of its marketing budget, not by charging you more.

That is also why cashback takes time. The retailer has to confirm you did not return the item before it pays the site, and the site then has to pay you. Expect weeks to months between buying something and the money being payable: Quidco’s own guidance says confirmation normally takes 3 to 6 months for the welcome bonus, and TopCashback’s bonus needs approved cashback, which takes a similar time. Cashback is a slow drip, not instant money.

Three rules keep you from losing cashback you have earned. First, always click through from the cashback site immediately before you buy — if you visit the retailer directly, browse elsewhere, or use a discount code the retailer does not allow with cashback, the purchase may not track. Second, do not use ad-blockers or private browsing for the purchase, because they can break the tracking. Third, keep the order confirmation email until the cashback is confirmed, so you can raise a missing-cashback claim with the order number if it does not appear.

TopCashback — the widest choice

TopCashback is the UK’s largest cashback site, founded in 2005, with over 25 million members worldwide and 5,500+ UK retailers including Amazon, Tesco, Argos, John Lewis, Sky, BT, Vodafone, Booking.com and most major insurers. Its free Classic membership costs nothing and pays out 100% of the commission it receives. There is a paid TopCashback Plus membership (about £5 a year) that adds extras — check the current price and benefits before paying for it, because Classic is enough for most people.

The £10 welcome bonus is paid through a referral link once you earn £10 of approved cashback at eligible brands within 180 days of joining (verified October 2026). TopCashback’s strength is breadth and big-ticket payouts: cashback on insurance, broadband, mobile contracts and travel can be £50 to £150 on a single purchase, which is where most of the real money comes from. Everyday shopping rates are usually 1% to 5%.

Quidco — the easiest bonus to unlock

Quidco, founded in 2005 and based in Sheffield, is the other big UK cashback site, with 5,000+ retailers and over 10 million members. Its welcome bonus is also £10 through a referral link, but the bar is lower: you only need £5 of confirmed cashback, with no deadline named (verified November 2026). That makes it the easiest bonus to clear of the two big sites — one £120 order at 5% cashback, for example, earns £6 and unlocks the £10.

Quidco pays out by bank transfer or PayPal from £1, which is lower than most rivals, and gift cards are also available. Its free Standard tier passes on the full advertised rate; Premium costs £1 in any month you shop and earn cashback, taken from your cashback balance rather than your bank card, and unlocks boosted rates at more than 1,500 retailers. If you shop through Quidco most weeks, Premium can pay for itself; if you shop rarely, stay on Standard.

Swagbucks — cashback plus surveys

Swagbucks is different: it is a rewards platform where shopping cashback (typically 1% to 10% at hundreds of UK retailers) sits alongside surveys, games and other paid tasks, all earning points called SB (100 SB is roughly £1, or $1 in the US). The headline welcome bonus is up to £10 (1,000 SB), but read the conditions carefully: you usually need to complete a qualifying offer or spend at a featured retailer within 30 days of joining, and the exact offer changes regularly. Swagbucks’ own site does not always list a sign-up bonus, so do not count on it until you see the live offer in the app.

You cash out by PayPal or gift card from £5. Swagbucks is worth it if you will actually do the surveys and offers as well as the shopping — as a pure shopping cashback site it covers fewer retailers than TopCashback or Quidco, and the per-purchase rates are similar. As a way to earn a few pounds in spare minutes, it is legitimate and long-running, run by Prodege since 2008.

Shopmium — groceries only, and genuinely useful

Shopmium is a free app for supermarket shopping. You browse the offers in the app, buy the product in-store or online at any major UK supermarket, then upload your receipt and scan the product barcode. Once the claim is approved — usually within a couple of days — the cashback goes into your Shopmium balance, and you can withdraw to your bank account or PayPal once it reaches £10.

The key difference is that Shopmium pays cashback on specific branded products, often 20% to 100% of the price, rather than a percentage of your whole shop. That makes it good for trying new products cheaply and bad as a general grocery discount: you only earn on the items with offers that week. New users can claim a free welcome treat through a referral code. One warning from users: Shopmium has charged an inactivity fee on dormant balances, so withdraw your money once you hit £10 rather than letting it sit.

How much can you really earn? £200 to £500 a year

A household that routes its normal online shopping, insurance renewals, broadband switch and one holiday through a cashback site can realistically earn £200 to £500 a year. The big payouts come from the big purchases: a car insurance policy, a broadband switch or a holiday booking can each pay £50 to £150. Everyday shopping at 1% to 5% adds up slowly — £300 a month of online shopping at 3% is £108 a year.

What does not work: buying things you would not otherwise buy because of the cashback. Spending £100 to earn £5 is not saving money. Cashback is a discount on spending you were going to do anyway, nothing more. Try our cashback calculator to see what your own spending is worth at realistic rates.

Payout tips

• Join both TopCashback and Quidco and check both before a big purchase — rates differ by retailer and by day, and the higher rate wins.
• Withdraw promptly. Do not leave large balances sitting in a cashback account for months; withdraw to your bank once you reach the minimum.
• Keep records. Note the date, retailer and expected cashback for big purchases so you can claim if it does not track.
• Check the exclusions. Gift cards, some sale items and certain payment methods are often excluded from cashback — and on Quidco, gift card purchases do not count towards the £5 needed for the welcome bonus.
• Do not pay for a premium tier unless you shop often. Quidco Premium is £1 in months you shop; TopCashback Plus is a small annual fee. Both only pay off if you use the site regularly.
