Cashback sites pay you part of the commission they earn when you click through to a retailer and buy something. You pay the same price, so it is money you would otherwise leave on the table.
How cashback sites work
- Join a cashback site for free.
- Search for the shop or deal before you buy.
- Click through from the cashback site and buy as normal.
- The cashback shows as "tracked" or "pending", then "confirmed" once the retailer pays the site, which can take weeks or months.
- Withdraw it to your bank, PayPal or as a gift card, often with a bonus for gift cards.
TopCashback vs Quidco
| TopCashback | Quidco | |
|---|---|---|
| Free account | Yes | Yes |
| Paid upgrade | Plus: up to £5 a year, taken from your cashback | Premium: £1 for each month you earn cashback, taken from your cashback |
| What the upgrade adds | Higher rates and bonus offers | Higher rates and payout bonuses |
| Best for | Often the highest headline rates | Regular promotions and bonuses |
Both sites set their membership terms themselves, so check the current details when you join. In practice the best approach is to have accounts on both and compare the rate for each purchase. Comparison tools and browser extensions can show both rates at once.
Where cashback adds up fastest
- Switching: energy, broadband, mobile, car and home insurance can each pay £20 to £100 or more in cashback.
- Bank accounts and credit cards: some pay large cashback amounts, but only switch if the product suits you.
- Travel: hotel and holiday bookings can earn a decent percentage on big spends.
- Big purchases: electricals, furniture and mattresses.
- Food shopping and takeaways: smaller amounts, but frequent.
Tips to get more cashback
- Always start at the cashback site. Going direct to the shop earns nothing.
- Clear your basket first and turn off ad blockers for that purchase, so the click tracks properly.
- Do not use other voucher codes unless the cashback site lists them. Outside codes can cancel your cashback.
- Screenshot your confirmation so you can claim if it does not track.
- Claim missing cashback. Both sites have a form for purchases that did not track.
- Stack it: cashback on top of a cashback credit card or rewards scheme, as long as you clear the card in full every month.
- Never buy just for the cashback. 10% back on something you did not need is still 90% wasted.
Is cashback taxable?
Cashback on your own personal spending is generally treated as a discount on what you bought, not income, so it is not taxed.
Other ways to earn cashback
- Banking apps and cards with built-in cashback offers at selected retailers.
- Supermarket loyalty schemes that give points or member prices.
- Receipt and survey apps, which pay small amounts for scanning receipts or answering questions. Slow, but they add up.
If you want a goal for the money, putting all your cashback into an emergency fund is a painless way to build one.
Common questions
Which is better, TopCashback or Quidco?
Neither always wins. Rates differ by retailer and change often, so the best approach is to be a member of both and check each time.
Are cashback sites safe?
The big UK sites have millions of members and have paid out for years. The main risk is cashback not tracking, which is why you should keep your confirmation emails.
How long does cashback take to pay?
Usually from a few weeks to a few months. Travel cashback is often only confirmed after your trip, and switching deals can take a few months.
