## Compared offers
- [TopCashback](https://topreferrals.co.uk/offers/topcashback) — TopScore 6.8/10. £20 sign-up bonus.

Britain's two big cashback sites cover broadly the same retailers, so the difference comes down to how much of the commission reaches you, the sign-up bonus, and how you get paid.

## The commercial model

This is the headline difference. [TopCashback](/offers/topcashback) **returns 100% of the retailer's commission** to members, funding itself through an optional Plus tier and gift-card margins. **Quidco keeps a small percentage** of each payout. All else equal, that makes TopCashback the higher-returning of the two on most transactions.

## The sign-up bonus

TopCashback pays a **£20 new-member bonus** (and £25 to the referrer), released once you earn **£10 of tracked cashback within 180 days**. Pick one substantial purchase you had planned — a broadband switch, a holiday, a big homeware order — and you'll clear the £10 threshold and bank the £20 on top. Quidco runs its own sign-up incentives from time to time, but TopCashback's combination of 100% commission and the £20 bonus is the stronger opener.

## Retailers and payouts

TopCashback lists **5,000+ retailers** (Quidco around 4,500+), and the two overlap heavily — but **individual rates vary by retailer**, so for a single big purchase it genuinely pays to check both. On withdrawals, TopCashback adds a **3–10% uplift on gift cards** for the likes of Amazon, Tesco, Costa and M&S, which is free extra money if you were going to spend there anyway.

## How cashback timing works

On either site, cashback **tracks** within days, then becomes **payable** weeks later once the retailer confirms the sale — longer for travel and insurance. The bonus is gated on confirmed cashback, so plan for the wait.

## The verdict

For headline value, the sign-up bonus and the gift-card uplift, **TopCashback wins** in 2026. The smart approach is to keep **both** accounts and check the per-retailer rate before each significant shop — but if you open one, open TopCashback.
