TopCashback vs Quidco – Which Cashback Site Pays More? (UK 2026)

The most common question people ask when they discover cashback sites is which one they should sign up to. The answer is both. TopCashback and Quidco are the two biggest cashback platforms in the UK, they’re both free to join, and the cashback rates on any given retailer can vary between them on any given day. If you only use one, you’ll occasionally miss the better rate.

This guide breaks down how they compare across the things that actually matter, so you can make an informed decision about how to use both of them.

TopCashback vs Quidco: how they compare

Retailer coverage

TopCashback covers over 6,000 retailers including all the major UK supermarkets, fashion brands, travel companies and insurance providers. Quidco covers a similarly large number. Both have excellent coverage. For everyday UK shopping you’ll rarely find a retailer that one has and the other doesn’t.

Cashback rates

This is the key difference between them, and it changes constantly. On a Monday, TopCashback might offer 6% cashback on a particular retailer while Quidco offers 4.5%. By Wednesday the situation might have reversed. Neither site consistently beats the other on every retailer. The practical solution is to spend thirty seconds checking both before a significant online purchase and use whichever is higher.

Payment speed

Both sites have similar payment timelines. After you make a purchase, cashback typically enters a pending state for anywhere from a few weeks to several months, depending on the retailer’s return policy. Once confirmed, you can withdraw to your bank account. TopCashback pays directly to your bank account. Quidco also offers bank transfer, PayPal, and gift card options.

Free vs paid tiers

TopCashback has a free account and a Plus account. The Plus account costs £5 per year, taken from your cashback earnings, and offers slightly higher rates on some retailers plus bonus offers. For most people the free account is absolutely fine. Quidco also has a free tier and a premium tier. Again, the free tier is sufficient for casual use.

Browser extension

Both offer browser extensions that automatically activate cashback when you visit a participating retailer. This removes the need to remember to go via the cashback site first. Installing both extensions means you get a notification whichever site has the better rate for the site you’re on.

Bonus offers and promotions

Quidco is particularly good for limited-time bonus offers where specific retailers pay elevated cashback rates for a short window. TopCashback also runs promotions but tends to compete more on the base rates than time-limited bonuses.

How much can you actually earn?

With moderate use of both sites, most UK families earn between £100 and £300 per year. People who are more systematic about it, who check rates before every significant online purchase and use both sites for insurance renewals and energy switching, can earn £500 or more. The cashback on energy switching and broadband in particular can be substantial, with some deals paying £50 to £100 per switch.

The verdict

Sign up to both. Start with TopCashback as your primary site, because it has consistently competitive rates across the widest range of retailers. Add Quidco as your backup, install both browser extensions, and spend thirty seconds comparing rates before anything significant. It costs you nothing extra and you’ll always get the best available rate.
