Cashback sites pay you for shopping you're already doing. It's free money, but most people either don't use them or use them wrong. Here's the full system.
How Cashback Sites Work
Retailers pay cashback sites a commission for sending them customers. The cashback site shares that commission with you.
Example: You click through TopCashback to ASOS. You buy a £50 jacket. ASOS pays TopCashback £3. TopCashback gives you £2.50, keeps £0.50.
You lose nothing. ASOS gets a sale. TopCashback earns a cut. Everyone wins.
The Big Three UK Cashback Sites
TopCashback
Pros: Highest cashback rates (no fees), clean interface, fast payouts.
Cons: Smaller retailer selection than Quidco.
Best for: Most people. Default choice.
Quidco
Pros: Largest retailer selection, frequent bonuses.
Cons: Premium membership (£1/year) for the best rates. Free tier exists but earns less.
Best for: Heavy users who shop everywhere.
Airtime Rewards
Pros: Links to your bank card, tracks automatically (no clicking through links).
Cons: Cashback paid as mobile credit only, lower rates than TopCashback/Quidco.
Best for: People who forget to click through cashback links.
How to Maximise Cashback
1. Check Both Sites Before Buying
TopCashback and Quidco offer different rates. Example:
- TopCashback: ASOS - 4%
- Quidco: ASOS - 5%
Always compare. Use whichever pays more.
2. Stack Cashback with Discount Codes
Cashback works on top of discount codes. Full stack:
- Find a code on CodeLand
- Click through TopCashback/Quidco
- Apply code at checkout
- Earn cashback on the discounted price
Example: £100 order, 20% code = £80. 5% cashback on £80 = £4 back. Total saved: £24.
3. Use Browser Extensions (Carefully)
Extensions like Pouch or Quidco Assistant auto-activate cashback. Convenient, but:
- They can conflict with manually clicked links (you lose cashback)
- They slow down your browser
- Some inject their own affiliate links
Safest method: Manually click through the cashback site every time.
4. Enable Cookies and Disable Ad Blockers
Cashback tracking relies on cookies. If you block cookies or use aggressive ad blockers, cashback won't track.
Quick fix: Whitelist cashback sites in your ad blocker, or disable it temporarily.
5. Don't Click Away After Checkout
Complete your purchase in one session. If you click through TopCashback, then leave the site and come back later, the tracking breaks.
When Cashback Doesn't Track (And How to Fix It)
Sometimes cashback doesn't appear. Common reasons:
- You used a voucher code not listed on the cashback site - Some codes invalidate cashback.
- Ad blocker interfered - Whitelist the site.
- You returned items - Cashback is clawed back on returns.
- You clicked through multiple cashback links - Only the last one counts.
How to claim missing cashback:
- Log into your cashback account
- Go to "Track Claim" or "Missing Cashback"
- Upload proof of purchase (order confirmation email)
- They'll investigate and credit you manually
Best Retailers for Cashback
High cashback rates (5%+):
- ASOS: 4-6%
- eBay: 1-2% (low rate but adds up on big purchases)
- Booking.com: 4-6%
- Currys: 3-5%
- Boots: 3-5%
Low cashback but worth it on big purchases:
- Apple: 0.5% (but £1,000 laptop = £5 back for clicking a link)
- John Lewis: 1-2%
Cashback Bonuses and Offers
Both TopCashback and Quidco run temporary "boosts":
- "Increased cashback" - e.g., ASOS goes from 4% to 10% for 48 hours
- "New member bonuses" - £10 cashback on your first £10 purchase
- "Refer a friend" - £5-£10 for each friend who signs up and earns cashback
Check the homepage before shopping - bonuses change daily.
Payout Options
TopCashback:
- Bank transfer (free, 2-3 days)
- PayPal (free, instant)
- Gift cards (sometimes boosted value, e.g., £10 cashback = £11 Amazon voucher)
Quidco:
- Bank transfer (free, 5 days)
- PayPal (£1 fee)
- Gift cards (boosted value)
Minimum withdrawal: Usually £10-£20.
Travel Cashback (Huge Savings)
Cashback on travel bookings is massive:
- Booking.com: 4-6% back (£200 hotel = £8-£12 back)
- Hotels.com: 6-8%
- Expedia: 3-5%
- British Airways: 1-2% (still worth it on a £500 flight)
Always check cashback sites before booking travel. You'll earn £20-50 on a single holiday booking.
Grocery Cashback (Harder But Possible)
Tesco, Sainsbury's, Asda don't offer cashback on regular grocery shops. But you can get cashback on:
- Tesco Delivery Saver subscriptions (one-off cashback when you sign up)
- Grocery gift cards (buy discounted gift cards via cashback sites)
- Ocado (3-5% cashback on deliveries)
Credit Card Cashback (Double Stack)
Some credit cards offer cashback on all purchases (e.g., Amex Platinum Cashback gives 0.5-1%).
The double stack:
- Click through TopCashback (5% back)
- Pay with cashback credit card (1% back)
- Total: 6% back
Only works if you pay off the card every month. Interest wipes out any savings.
Cashback Isn't Instant
Cashback takes time to process:
- "Pending" period: 7-90 days (retailers confirm you didn't return the item)
- "Payable" period: Once confirmed, you can withdraw it
Be patient. It'll arrive.
