How do UK cashback sites work? How do they make money? How much cashback can you earn with their cashback deals and which cashback site is the best one to use?

In this guide and cashback site comparison, Bobatoo will go through everything you need to know about cashback websites and identify the best ones, making sure you are well-informed and know how to get the most out of them.

What you will learn...

How do cashback websites work?

When shopping online, cashback websites allow you to click on various deals and offers, which take you directly to the sellers' websites to buy products. When you buy their product(s) through Quidco, they will give you money back for every purchase you make. The amount of money you can get back for your purchases is typically around 5%-15% - so it can add up to a considerable amount of cashback for expensive items.

How do cashback sites make money?

Cashback websites are able to pay you to shop because they have 'affiliate' deals with the shops they feature on their site. This means that they receive a percentage of any sales they refer to that shop.

When you go to an online store via a cashback website, your visit will be tracked and the cashback site will receive a percentage of whatever you spend on that site as commission. The cashback you then receive is made up of this commission.

Cashback websites simply share their affiliate commission with you.

What are the top UK cashback websites?

When deciding what cashback website to sign-up to and use, you should be thinking about choosing one that pays the highest percentage of their commissions.

Some cashback brands pay as little as 50%, whereas the top two below are both 100% payers. Paying 100% of the commission may seem like an unsustainable way to do business, but they are able to pay 100% cashback as the high level of customers they send to online brands enables them to be paid bonuses by the brands - so they get paid as well as paying you 100% of the commission you generate.

Here are Bobatoo's short reviews of the top cashback and money-saving sites in the UK:


Curve is an all in one money app that combines all your credit cards, debit cards, and loyalty cards in one whilst also allowing you to earn cashback from well-known retailers and websites. 

Depending on your choice of card, you will get different types of benefits such as the number of retailers where you can earn your cashback from when you spend in-store or online to increased amounts for fee-free foreign ATM withdrawals to phone and travel insurance.

Curve’s free subscription ‘Curve Blue’ will let you select 3 retailers to earn cashback from for up to 90 days, whereas the monthly subscription cards such as ‘Curve Black’ and ‘Curve Metal’ will allow you to choose between 3 and 6 retailers with no time limit on when you can earn cashback. 

Each time you use your card with your chosen retailers, the cashback you earn is added into a section of your Curve card app called Curve Cash. You can spend your Curve Cash points straight away at any physical or online shop, exactly as you would with any other card in your wallet or the Curve app. Just make sure you select your ‘Curve Cash Card’ as your active payment option before making a purchase.

best cashback sites to use when shopping online

Cashback apps (UK)

Rather than opening up your internet browser and signing in online every time, an app makes for quicker shopping, thus quicker cashback earned. While Bobatoo’s cashback site comparison review has focussed on the best cashback sites in the UK, not all of them currently have an app, but thankfully – most do! The ones that do, are:

Tips to get the most out of cashback websites

With both TopCashback and Quidco cashback websites it's relatively easy to sign up to a free account, browse the offers, shop online and start building up your cashback. But if you want to get the full benefits of using them and maximise the amount of cashback you receive, then follow the tips below:

Cashback is not always guaranteed

Think of the cashback you receive after shopping via these websites as a bonus, rather than an absolute guarantee. Sometimes, there can be tracking problems which mean your visit, and subsequent spending, isn't recorded (although this is very rare). Other times, there may be attribution issues and the online store disputes the commission payment to the cashback site.

Unlike getting cashback from a retailer, you have very little consumer rights when it comes to getting money from cashback websites. Therefore the best way to approach it is to look at the potential cashback you may earn as a nice bonus, rather than letting it drive your purchasing decisions.

Cashback is not your money until it's in your bank account

It's always nice to see your cashback account start to fill up with cash after you've been spending, but the golden rule is that the money is not yours until it is in your bank account.

The amount you see in your cashback accounts may still be subject to disputes and declined payments, plus there is always the risk that the company may go bust and leave you with no recourse to access your cashback.

Always withdraw your cashback at the earliest opportunity

Most cashback websites have a minimum threshold before you can withdraw your money - usually between £50 and £100. You should always take your money out as soon as possible, rather than let big amounts build up in your account.

As well as missing out on any interest on the cash you have earned, if the cashback site goes bust or makes changes to its payment policy while you have a lot of money in there you could be in for a nasty shock.

Don't make purchases based on the cashback amount

It's easy to start browsing the offers on cashback sites and get seduced by the levels of cashback available on certain products or from certain brands - but you should only be looking to earn cashback on products you were already planning to buy.

That way you are effectively earning money for nothing, as you were going to spend that money anyway. If you start making purchasing decisions based on how the cashback will offset the cost, then you are effectively losing money.

Regardless of the cashback on offer, you should base your purchasing decisions on getting the best possible deal. If you choose to buy something purely because of the cashback that is on offer, and then that cashback doesn’t come through for whatever reason, you could find yourself badly out of pocket.

For example, if you are looking for a new laptop and spot a 5% cashback offer on one that costs £499 - netting you £25 in cashback -  you may feel you are getting a great deal. However, you could have used a price comparison site and found the exact same laptop model currently on sale for just £399.

Be aware of ‘cookie trails’

One of the most important considerations when using cashback sites is the online journey you have to make in order to claim your cashback. When you click a link from a cashback site to an online retailer, you are tracked by a cookie. 

To qualify for the cashback offer there must be a clear ‘cookie trail’ which shows it was the cashback site that first referred you to the retailer.

If you have already been on the retailer’s website before deciding to take advantage of the cashback offer, you will have to delete your cookies. If you don’t, your previous visit to their website will still be tracked and the cashback site may not be viewed as the original source of the sale.

Sign up for in-store cashback deals

As well as earning cashback from shopping online, cashback websites also now allow you to build cashback when shopping in stores with your debit or credit card.

To do this you need to register your debit/credit card with them so they can track your purchases in store. There's not a great amount of retailers currently on the in-store cashback scheme, but they are growing all the time and there's currently some big names like The Body Shop, Disney Store, Uniqlo and Starbucks offering up to 5% in-store cashback.

Hopefully, Bobatoo's guide has given you a good insight into how you can receive cashback with the best reward sites in the UK.

For further, related information, see the guides listed below. Alternatively, sign up to one of the above-mentioned cashback sites and start earning and receiving rewards on offers and purchases now.

Happy cashback shopping!
