TopCashback vs Quidco: Which Cashback App Pays More in 2026?

What are cashback sites, and how much can you earn?

This article compares TopCashback and Quidco directly so you can decide which to use, or whether to use both. Cashback sites are free online services that pay you a percentage of your spend every time you shop through their links (meaning you click a retailer link on the cashback site before buying, and the site pays you back a share of what you spend). They work by receiving a referral commission from retailers and passing most of it back to you as cash. When you click through to a retailer via TopCashback or Quidco and complete a purchase, the retailer pays the cashback site a referral fee, typically ranging from 1% to 15% of the transaction value, and the site returns the majority of that fee to your account. According to The Second Income UK, members who check both platforms before every purchase consistently come out ahead of those who rely on just one site, often by £30 to £60 per year on the same spending habits.

Using TopCashback and Quidco together, most UK shoppers can realistically earn £150 to £400 per year on purchases they would have made anyway. It costs you nothing extra and takes about 10 seconds to set up per site. In 2026, both TopCashback and Quidco have expanded their retailer networks significantly, with combined coverage now exceeding 9,000 UK and international merchants across categories from supermarkets to insurance providers.

What makes TopCashback worth joining?

TopCashback is genuinely free to join and consistently pays the highest cashback rates for big-ticket categories. There is no monthly fee on the standard plan and no commission cut from your earnings.

TopCashback is the UK's highest-rated cashback site and generally pays the highest rates. They operate a genuinely free model: unlike Quidco, there is no monthly fee and no commission cut on the basic plan.

Their strength is big-ticket purchases: broadband switches, insurance renewals, and financial products. A single broadband switch can earn £80 to £120 cashback, and insurance renewals regularly pay £30 to £60. The Second Income UK found that over a 12-month period, a household switching both broadband and home insurance through TopCashback could realistically recover £150 or more in cashback from those two categories alone.

What does Quidco offer that TopCashback does not?

Quidco edges ahead for everyday shopping categories such as supermarkets, fashion, and smaller purchases, and its mobile app is widely regarded as more polished for day-to-day use.

Quidco is TopCashback's main rival and has a loyal following. Their free plan deducts £1 per month from your cashback earnings, so if you earn £20 cashback in a month, you receive £19. Not a dealbreaker, but worth knowing upfront. The £1 monthly deduction equates to £12 per year, so you need to earn at least that before Quidco's free plan delivers any net benefit. Quidco's Premium plan at £5 per month unlocks boosted cashback rates across more than 1,500 retailers, and for heavy shoppers the additional rates can more than offset that monthly cost. As The Second Income UK explains, Quidco's in-store cashback feature for linked debit and credit cards also gives it an edge for shoppers who regularly buy from high street retailers such as Boots and H&M, with typical in-store rates running between 2% and 6% depending on the retailer and promotion.

Where Quidco shines is everyday shopping: supermarkets, fashion, and smaller purchases tend to have competitive or better rates than TopCashback. Their app is also slightly more polished for day-to-day use, earning an average rating of 4.4 out of 5 on Google Play as of early 2026.

How do TopCashback and Quidco compare head to head?

Across most categories, TopCashback leads on headline rates, but Quidco is more competitive for everyday purchases. The table below captures the key differences.

Which should you use: TopCashback, Quidco, or both?

Use both. They are both free to join (TopCashback fully free, Quidco free with a £1 per month fee taken from earnings), and the 60 seconds it takes to sign up to each will earn you back many times over. In 2026, both platforms continue to expand their retailer networks, and rates on popular categories such as travel and utilities remain among the highest they have been in several years.

In practice: before any significant online purchase, check both sites and go with whichever is paying more. For insurance and broadband in particular, always check TopCashback first, those deals consistently pay the highest cashback rates on the site. According to The Second Income UK, shoppers who build this two-second habit into every online purchase typically see their annual cashback total rise by 20 to 35 per cent compared with using a single platform.
