5 Tips to Maximise Your Cashback
Small habits that add up to a lot more money back over the year.
Stack multiple apps
Use TopCashback or Quidco for online shopping, Airtime Rewards for day-to-day card spending, and Shopmium for groceries. They all run at the same time — there's no conflict.
Always check for a cashback rate before buying online
Before checking out anywhere online, open TopCashback or Quidco and search for the retailer. Even large supermarkets and travel sites often have rates you'd miss otherwise.
Use cashback for big purchases
Cashback rates on insurance, broadband and holidays are often 5–20% — far higher than on everyday shopping. Always check before renewing any annual policy.
Be patient with tracked cashback
Cashback from browser extension apps can take 30–90 days to confirm and pay out. Don't cancel orders or return items if you want the cashback to track correctly.
Grab sign-up bonuses first
Most cashback sites offer a joining bonus (typically £5–£30) for new members. Sign up via a referral link to get both a bonus and extra cashback on your first purchase.
Common Questions
Straight answers to what people ask us most about cashback apps.
-
Are cashback apps actually free? ▼
Yes — every app on this page is free to join and use. They earn money when you make a purchase through them, and pass a share of that commission to you as cashback. Quidco has an optional paid tier with slightly higher rates, but the free tier works well for most people.
-
Can I use more than one cashback app at the same time? ▼
Yes. Using multiple apps simultaneously is one of the best ways to maximise earnings. For example, use TopCashback or Quidco for online purchases, Airtime Rewards for in-store card spending, and Shopmium when grocery shopping — they don't conflict.
-
How long does cashback take to arrive? ▼
It varies. Shopmium and Airtime Rewards tend to be faster (often days). Browser extension apps like TopCashback and Quidco typically take 30–90 days for cashback to confirm, as retailers need to verify you haven't returned the item.
-
Why does cashback sometimes not track? ▼
Common reasons: ad blockers or other browser extensions interfering, clicking another link after the cashback link (e.g., a voucher code), or using private/incognito browsing. Always disable ad blockers and go directly from the cashback link to the retailer.
-
Is cashback taxable in the UK? ▼
Generally no. HMRC treats cashback as a discount on a purchase rather than income, so you don't need to declare it on your tax return. However, if you earn significant amounts through referrals or other means, it's worth checking with a tax adviser.
-
Which cashback app is best for grocery shopping? ▼
Shopmium is the strongest for grocery cashback — it works at Tesco, Sainsbury's, Asda, Morrisons and more, and doesn't require any specific loyalty card. For general online grocery delivery (e.g. Ocado), TopCashback or Quidco often have rates too.
