How to maximise cashback and loyalty rewards in the UK. Best cashback sites, supermarket loyalty points, credit card rewards, and stacking strategies.

Cashback Card Rates
Cashback credit card rates, caps, annual fees and introductory offers differ between cards and change over time, so this page does not list them. Check the card issuer’s own page for the current rate and fee, and see Which?’s dated comparison of cashback credit cards for a side-by-side view.
Using Rewards Cards
| Rule | Why |
|---|
| Pay in full monthly | Interest cancels rewards |
| Don’t spend more | To earn rewards |
| Check where accepted | Amex not everywhere |
| Have backup | Visa/Mastercard |
Is a Rewards Card Worth It?
Example (simplified, at an assumed 1% rate). At 1% cashback, £5,000 of annual spending returns £50, £10,000 returns £100, £15,000 returns £150 and £20,000 returns £200. Check the actual rate, any cap and any annual fee for the card you are considering. The cashback only counts if you pay the balance in full each month.
Stacking Rewards
How to Stack
| Layer | Example |
|---|
| 1. Cashback site | Cashback rate shown on the site for that retailer |
| 2. Retailer loyalty | Points on purchase |
| 3. Cashback card | Card’s cashback rate |
| Total | The rates add together, but check each is available on the same purchase |
Stacking Example: Hotel Booking
| Layer | Reward |
|---|
| TopCashback | Cashback at the rate shown for the hotel site |
| Hotel loyalty | Points for stay |

High-Value Opportunities
Larger purchases and switching transactions (insurance renewals, utility switches, broadband, big-ticket items, travel bookings) are where a cashback site is most likely to pay a meaningful amount. Check the current amount or rate on the site before you buy.
Don’t let cashback change your spending behaviour. These schemes work best when you earn rewards on purchases you’d make anyway.
