A very warm welcome to cashback - one of Quidsy members favourite ways to earn!

Why is this? Simply put, you get free money for things you already do. It's one of the smartest and simplest ways to grow your profit pot. With a total of £55 in sign up offers plus £100/year from cashback.

What is Cashback?

Cashback is a simple concept: you shop online, you get money back.

Brands pay cashback sites money for sending them customers. The cashback sites then share that money with you. Everyone wins.

It's not a voucher - it's actual cash that lands in your bank account.

You're just getting paid cash back for shopping you'd do anyway.

You can join 3 cashback sites with sign-up bonuses worth a total of £55, plus you earn ongoing cashback from your shopping and other offers. In this guide we will cover:

Why do retailers give you free cash?

Retailers pay cashback sites as part of their marketing spend.

They'd rather pay for real customers than for adverts that might not work. So when you shop through a cashback site, the retailer pays the site a commission, and that site shares most of it with you.

Chris's Tip:

Think of it as free money for things you'd do anyway, nice!

Types of Cashback Offers

There are two main types of cashback:

Type 1) Shopping Cashback

You earn a small percentage back when you shop at retailers via a cashback site.

For example:

✓ 5% back at Argos

✓ 8% back at Boots

✓ Around 10% back on insurance or broadband

This type adds up fast if you regularly shop online.

Type 2) One-Off Cashback

You earn a bigger, one-time reward for completing a specific action.

These are sometimes called sign-up offers and include actions like:

✓ Signing up for a bank account (£20 to £100+)

✓ Joining a broadband provider (£30 to £80)

✓ Taking out an insurance policy (£20 to £60)

Perfect if you want a quick hit of profit, awesome!

Frequently Asked Questions

Usually yes, but check the terms. Some offers say "not valid with other promotions." The safest approach: apply your discount code, but click through the cashback site first. Worst case, the cashback gets rejected but you still keep the discount.

It varies by site and offer type - but the general rule of thumb is that brands payout once their returns period has passed. TopCashback and Quidco typically pay within 4 to 8 weeks for shopping cashback. One-off sign-up bonuses like bank accounts or broadband usually track within 7 days and pay out once confirmed. We have listed the typical payout times for each site in the guide above.

Absolutely, and we recommend it! You can and should be a member of all 5 cashback sites. However, you cannot use multiple sites for the same purchase. Different sites offer better rates for different retailers. Before any purchase, check which site has the highest rate. This is where our Cashback Comparison tool comes in handy. It takes 2 seconds and can mean the difference between 3% and 8% back.

Don't panic. Make sure you take a screenshot of your order confirmation immediately after purchase. Then submit a "missing cashback" claim through the cashback site (usually under Help or My Account). Most claims get approved within 2-3 weeks if you have proof. TopCashback is particularly good at honouring these.

It depends on the brand you’re looking to get cashback on. TopCashback often has the highest rates for big-ticket items and has the widest coverage of brands. But Quidco might beat them for certain shops, as they have more of the popular brands. Thi is why we built our free Cashback Comparison tool. Check it before every purchase to never miss the best rate.

No. The taxman doesn't count cashback as income - it's treated as a discount on your purchase. You do not need to declare it.

When	Right	Time
