You can earn £700 to £1,300 a year back on money you’re already spending, and most people doing cashback properly are only using one or two of the six ways that actually pay. That’s the gap this guide closes.
Most cashback content covers one method well, usually the affiliate-site model, and either ignores the rest or lumps them into a vague paragraph. We’ve tested the apps ourselves, worked through the actual maths method by method, and included the two earners most guides leave out entirely, so you can see exactly what’s worth your time.
What is cashback?
Cashback is money returned to you for spending you’d have done anyway. It works two ways.
Rewards cashback is where you get a percentage of your spending back as points, credit or cash through an app, a shopping site, or a card. Till cashback is physical cash handed over at a shop checkout alongside a card purchase, which is really just a free way to avoid the cash machine.
Rewards cashback is funded in one of two places. Cashback sites and apps (TopCashback, Quidco, Gains App and similar) earn a commission from retailers for sending them a paying customer, and share a slice of that commission with you. (Disclosure: Gains App is built by the Up The Gains team.)
Cashback bank cards and card-linked schemes are funded differently, through the interchange fee merchants already pay every time a card is used. A small cut of that fee is routed back to the cardholder instead of staying with the bank.
Either way, the retailer or card network is paying for something they’d be paying for regardless, marketing spend or transaction processing. Cashback just redirects a slice of that existing cost to you.
Beyond that basic split, cashback in the UK now spans gift cards, receipt-scanning apps, bank switching bonuses and more, which is what the rest of this guide covers.
It’s also worth being clear about what cashback isn’t. Loyalty points like Clubcard or Nectar are tied to a specific retailer regardless of payment method, whereas cashback follows the payment and usually works across many retailers.
It isn’t a discount code either, since a voucher cuts the price at checkout while cashback pays you back afterwards. And it isn’t guaranteed income: every method here depends on you spending in a way that qualifies, so what you earn scales with what you’re already buying.
How does cashback work?
Cashback means getting a percentage of money back on spending you’re already doing, whether that’s a weekly shop, an online order, or a bill renewal.
It’s funded from the same two places covered above: affiliate commission for cashback sites and apps, and the card interchange fee for cashback cards and card-linked schemes. Nobody is losing money to fund your cashback, the cost was being paid regardless.
Speed and reliability vary a lot by method, which is worth knowing before you decide where to focus. Gift card and card-linked cashback are the fastest and most reliable, since the transaction itself is the proof and there’s nothing to verify afterwards.
Affiliate cashback is the slowest and least certain, since it depends on a tracking cookie firing correctly and the retailer later confirming the sale. That’s why it’s behind most “my cashback didn’t track” complaints on MSE’s forums.
Cashback bank cards sit in the middle: reliable because there’s no tracking involved, but slower to add up since the rate is usually the lowest of the bunch.
Receipt-scanning apps are reliable in the sense that a successful scan always pays, but unpredictable in what’s actually on offer week to week.
One clarification before the methods list: till cashback isn’t one of the six earning methods below, since you’re withdrawing your own money at the checkout, not earning anything.
The main ways to earn rewards cashback in the UK are gift cards, affiliate sites, card-linked offers, cashback bank cards and receipt-scanning apps, each explained in full below with realistic annual figures.
The 6 ways to earn cashback (and what each pays a year)
1. Gift card cashback on everyday spending
Buy a digital gift card in an app, then spend it instead of your bank card. Cashback lands instantly, since the app buys the card from the retailer at a discount and shares a slice of it with you. For the full mechanics, see how gift card cashback works.
Gains App leads here, since gift card cashback on groceries and everyday spending is its core feature: connect your bank through Open Banking and it surfaces the offer for the supermarket you actually shop at, rather than a generic retailer list.
Cheddar and EverUp run the same instant-gift-card model at similar rates, while HyperJar takes a different angle, adding prepaid jars that grow at a fixed rate while you commit money to a brand ahead of spending it.
On a typical £400 a month food shop, a 2-4% rate works out at roughly £95-£190 a year on groceries alone, the lowest-friction method here since it simply replaces a payment you’re already making.
The same mechanic works well beyond the weekly shop too: gift card apps cover clothing retailers, coffee and restaurant chains, DIY and household stores, and travel brands, and non-grocery rates at time of writing are frequently higher than grocery ones.
On the same conservative basis as the grocery figure, that’s worth roughly £200-£450 a year on top, which most guides skip since they only look at the supermarket use case (full workings below).
The one everyday category it does not reach is fuel. Supermarket gift cards are generally excluded at petrol stations, and the digital cards sold inside cashback apps carry that exclusion even where a physical gift card bought in store might work at the kiosk. Our guide to cashback on fuel covers what does pay there.
We’ve broken the full hack down step by step in our supermarket cashback guide, and ranked every gift card app in our best cashback apps UK roundup.
2. Receipt-scanning apps
Shopmium, CheckoutSmart and GreenJinn pay on selected branded products regardless of how you paid, so they stack on top of the gift card hack rather than competing with it. How receipt scanning cashback works covers the full mechanics.
You photograph your receipt after a normal shop, and the app matches it against whichever offers are live that week, sometimes a small percentage, occasionally the full price of a product back as a trial incentive.
Earnings are spikier than gift card cashback: some weeks nothing matches your basket, other weeks a strong match lines up with your list. A realistic average across two or three apps is £120-£300 a year for someone who checks them regularly.
The offers rotate weekly, so checking before you shop, not after, separates the top of that range from close to nothing. Our supermarket cashback guide covers how to run all three alongside the gift card method on one shop.
3. Bank switching
This is the method most cashback guides leave out entirely, which is a mistake: it’s one of the highest-value things you can do with half an hour of admin.
Switch your main current account to a new bank via the Current Account Switch Service and most major banks pay a cash bonus for doing it, typically £175-£240 per switch at the time of writing. It usually requires a minimum deposit and a couple of active direct debits within a set window.
The top of that range includes extras some accounts pay on top, such as monthly rewards.
You can’t switch the same bank twice in quick succession, and offers change regularly, so it isn’t a method you repeat every month. Doing one or two switches a year realistically nets £150-£500, and stacking a switch with a cashback site’s own bonus can push an individual switch higher still.
Full current offers, bank by bank: free money offers.
4. Bills, insurance and broadband via affiliate sites
TopCashback and Quidco lead this one, built on their affiliate model: click through their link before you renew broadband, switch energy supplier, or take out insurance, and you get a share of the commission the provider pays the site.
Because the payout depends on a tracking cookie firing correctly, this is also the method most prone to going wrong, and our guide on tracking that has not worked explains how to claim a missing payout back.
This isn’t a recurring weekly earner like groceries, it’s a handful of bigger one-off payments as contracts come up for renewal, home insurance once a year, broadband every 12-18 months, car insurance annually, and each payout can be larger than a whole month of grocery cashback.
A household that routes its annual renewals through a cashback site can realistically clear £100-£200 a year this way. The habit to build is checking before you renew, not after, since the click has to happen before the purchase for tracking to register.
Our best cashback apps UK roundup covers how TopCashback and Quidco compare for this. We have broken down both routes, reward current accounts and one-off switching cashback, in our guide to cashback on bills and insurance.
5. Cashback bank cards
A current account or credit card that pays a flat 0.5-1.5% back on spending, credited automatically each month with no app to check and no offer to claim. Cashback credit cards explained breaks down how the rate is funded.
It’s the lowest-maintenance method here, and the lowest-yielding on its own: worth roughly £50-£150 a year depending on how much spending runs through the card, but free to run once it’s set up.
The main trade-off is that cashback cards often carry an annual fee or higher interest rate than a standard account, so it’s worth checking the fee against your typical spend, since it rarely pays for itself on light spending alone.
Where it earns its place is as a background layer underneath every other method, paying whether or not you remember it exists. Fuel is one of the few categories where a cashback card is the only realistic route, which we cover in cashback on fuel.
6. Card-linked cashback
Link a card once through Airtime Rewards and cashback applies automatically at participating retailers, typically 1-5%, redeemed against your mobile bill once you clear the minimum. Card-linked cashback explained covers how the automatic matching works.
It only pays at retailers the scheme has a deal with, so coverage is patchier than the other methods, which keeps a typical year’s earnings to around £20-£60.
But there’s genuinely nothing to do after the initial setup, no gift card to buy, no receipt to scan, no link to click. It’s free money layered on top of however you already pay, even if it’s the smallest number in this guide.
The maths: what a typical household can earn
Nobody else publishes the full arithmetic on this, most guides give you a headline number without showing how they got there. Here it is, method by method.
| Method | Realistic annual range | Effort | Learn more |
|---|---|---|---|
| Gift card cashback (groceries) | £95-£190 | Low: pay with a gift card instead of a bank card | Supermarket hack |
| Gift card cashback (other spending: clothing, eating out, household, travel) | £200-£450 | Low: same gift-card habit, applied to non-grocery purchases | How it works |
| Receipt-scanning apps | £120-£300 | Medium: check offers and scan receipts regularly | Supermarket hack |
| Bank switching | £150-£500 | Medium: one-off admin per switch, a few times a year at most | Current offers |
| Bills, insurance and broadband (affiliate) | £100-£200 | Low: click through before you renew | Full guide |
| Cashback bank card | £50-£150 | Very low: set up once, earns automatically | How it works |
| Card-linked cashback | £20-£60 | Very low: link a card once, earns automatically | How it works |
| Total (engaged household) | £700-£1,300+ |
Add up every row at its top end and you get £735-£1,850, but no real household hits the top of every range in the same year. We quote £700-£1,300 as the realistic engaged-household band: the low end assumes you’re nearer the bottom of most ranges, and the “+” covers the rare household that maxes out the whole stack.
Want to run this against your own spending instead of ours? Gains App’s calculator uses the same ONS-grounded benchmarks referenced below.
Where the second gift-card row comes from. Most guides only cost out gift-card cashback on groceries, but the same apps sell gift cards for clothing, eating out, household stores and travel too, and that spend is real and ongoing for most households.
We used Gains App’s own published spending benchmarks, credited to ONS household spending data, as the base: clothing £30/week (£1,560/year), eating out and social spending £100/week (£5,200/year), household goods £30/week (£1,560/year), and travel £2,500/year, £10,820 a year in total non-grocery spend a gift-card app can realistically reach.
For the rate, we checked live cashback at a handful of non-grocery brands at time of writing:
- 2.5% at M&S
- 2.5% at B&Q
- 3.25% at Argos
- Up to 8-9% at JD Sports and Starbucks
- As much as 10% at several restaurant chains
To stay conservative, since coverage won’t always land on the best-rate brand (Amazon, for comparison, pays just 0.5%), we’ve applied the same 2-4% band used for the grocery figure. That’s £216-£433 a year, rounded here to £200-£450.
The higher rates we observed, and Gains App’s own homepage claim of an average 7% cashback across everyday spending, are treated as upside rather than the baseline.
The £700-£1,300 figure includes bank switching, which most competitor guides skip: leave it out and the band drops to roughly £550-£850 on the other six methods alone.
A casual household running just two methods, say gift card cashback and a cashback bank card, lands more realistically around £250-£450 a year. The full range is what running the whole stack gets you, not the bare minimum.
The effort column matters as much as the pound figures: the two lowest-effort methods, the cashback bank card and card-linked cashback, are also the two smallest earners.
If your time is limited, set those two up first, add gift card cashback next since it replaces spending you’re already doing, then come back to bank switching and receipt apps when you’ve got half an hour spare.
How to stack cashback methods
None of these six methods cancel each other out, and on a single purchase you can layer several at once. Here’s the order that works, using a supermarket shop as the example.
Scan your loyalty card first (Clubcard, Nectar, Asda Rewards), since the till reads what you buy, not how you pay, so points earn regardless of what happens next.
Pay with a gift card bought through Gains App, Cheddar or EverUp instead of your bank card, since that’s what triggers the instant cashback. Then scan the same receipt through Shopmium, CheckoutSmart or GreenJinn afterwards, since receipt apps pay on specific products and don’t care how you paid for them.
If the card you used to buy the gift card itself pays cashback, that’s another 0.5-1.5% underneath the whole stack for no extra effort. Card-linked cashback through Airtime Rewards sits in the background too, triggered by that same card rather than the supermarket transaction.
Order matters: scanning your loyalty card after paying, rather than before, sometimes means the till treats it as a separate, unlinked transaction and the points don’t attach. Get into the habit of scanning first every time.
Applied to a single £100 shop, that stack can realistically return £5-£8 in combined cashback and points on groceries you were buying regardless. Our supermarket cashback hack guide walks through this order in more detail.
The same principle extends beyond groceries: route a bill renewal or holiday deposit through an affiliate site and pay with a cashback card, and you’ve stacked two methods on a purchase you were making anyway. Bank switching is different, a one-off action worth doing alongside everything else rather than something to stack per purchase.
The one place stacking doesn’t work is between two versions of the same mechanism. You can’t get affiliate cashback from both TopCashback and Quidco on the same purchase, since only one can own the tracked click, and a separate voucher code can void affiliate tracking altogether.
Stacking works when the methods are structurally different, not when you’re doubling up on the same one.
Golden rules and watch-outs
Cashback is genuinely close to free money when you do it right, but there are a handful of ways to lose the benefit or trip yourself up.
Never spend just to chase cashback. If a purchase only makes sense because of the cashback attached, it isn’t a good deal, it’s spending you wouldn’t otherwise do with a discount attached. Every method in this guide works on money you were already going to spend.
Cashback isn’t guaranteed until it’s paid out. Affiliate tracking can fail, particularly with an ad blocker, cookies disabled, or a separate voucher code applied at checkout, which can void the tracking altogether. If a purchase does not track, our guide on why cashback fails to track covers the causes and how to claim it back.
If a claim doesn’t show up within the stated window, raise a missing claim rather than assume it’ll sort itself out. Stick to one cashback browser extension at a time, since running two means only one gets credit for the click.
Gift cards carry their own small risks. You’re pre-paying, so only load what you’ll actually use, an unused balance isn’t cashback, it’s money parked somewhere you might forget.
You also lose Section 75 card protection when you pay with a gift card, so this method suits routine spending rather than a big one-off purchase, and it’s worth checking expiry dates too.
Respect withdrawal minimums. Most apps hold your balance until you hit a minimum cashout, anywhere from £1.50 to £10, so small balances can sit unclaimed if you only use an app occasionally. Spreading yourself across too many apps, rather than a focused two or three, is the most common reason people never see the withdrawal screen at all.
Bank switching bonuses have strict terms. Miss the direct debit window or fall short of the deposit threshold and you can lose the entire bonus, so set the direct debits up on day one and keep the account lightly active afterwards, since some banks claw the bonus back if it’s closed too soon.
Treat it as a bonus, not income, and keep your data tidy. Cashback tops up money you’re already spending, it isn’t a salary substitute, and some months will be quieter than others.
Several methods connect to your bank via Open Banking or track your browsing, which is standard for the providers named here. It’s still worth sticking to apps and sites you recognise and checking they’re FCA regulated where relevant.
