How to Compare UK Credit Cards (Without the Jargon)

Independent guide - not affiliated with or endorsed by any UK bank or card issuer. Rates and offers change often and depend on your circumstances; confirm the live terms on the issuer's site and run its eligibility checker before you apply.

Start here: pick the one number that matches how you'll actually use the card, then sort by that and ignore the rest. Paying the balance every month? The APR barely matters, so look at the cashback or points rate and any fee. Carrying a balance from an old card? You want the 0% balance transfer period and the transfer fee, and the rewards rate is noise. Trying to build or rebuild a credit file? You're looking at whether you're likely to be accepted and the credit limit, not the headline rate. Three different shoppers, three different sort columns.

The three numbers that actually decide it

UK cards advertise a representative APR. Under the FCA's definition of representative APR, at least 51% of the people accepted as a result of the advert must be expected to get that rate or better. The rest can be offered a higher rate, so the number on the advert isn't a promise to you. That's the first jargon trap. Here's what each shopper should look at first.

• If you clear the balance monthly: the reward rate and any annual or monthly fee. APR is irrelevant because you don't pay interest on purchases.
• If you're moving debt across: the 0% length and the one-off transfer fee. A longer 0% window with a higher fee can cost more than a shorter window with a lower fee; do the sum below.
• If you're spending and repaying over a few months: the 0% purchase period, then what the rate becomes afterwards.

You can compare the cards we track on our UK credit card comparison.

A worked example: the balance transfer fee trap

Say you owe £3,000 and plan to clear it in 18 months with equal payments. Both cards are hypothetical; the rates and fees are assumptions for illustration.

On these assumptions the fee-free card is cheaper, even though you pay some interest. Raise the balance, lengthen your repayment plan or raise Card B's revert rate, and Card A can win. The lesson: the best balance transfer card depends on your repayment timeline, not on the biggest month count in the advert. Sort by total cost over your timeline. Our UK balance transfer guide covers the current market in more detail.

The small print that quietly changes the answer

Once you've sorted by the right number, two or three cards usually tie. The tie-breakers are in the terms.

• Section 75 protection applies to credit card purchases over £100 and up to £30,000, making the card provider jointly liable with the seller if something goes wrong. MoneyHelper explains how you're protected when you pay by card; our Section 75 guide has the details. Since 15 July 2026 the FCA also regulates many buy now, pay later agreements; see buy now, pay later vs credit card.
• Non-sterling fees: many cards add a percentage to spending in other currencies. If you travel, compare fee-free options in our guide to credit cards for use abroad.
• What the rate becomes after the 0% ends. A 0% deal that reverts to a high APR is fine if you've cleared it and costly if you haven't. Diarise the end date.
• Minimum repayments only clear a small slice. The FCA has rules on persistent debt because minimum payments can keep people in debt for years.

Who should skip the comparison entirely

If you've missed payments recently or have a thin credit file, don't apply for the headline rewards cards; a declined application still leaves a hard search on your file. Use an eligibility checker that runs a soft search first, or start with a credit-builder card and a low limit. Our UK credit builder cards guide and UK credit score guide explain how.

And if you never carry a balance and spend modestly on your card, a fee-paying rewards card rarely pays for itself; a free cashback card is usually the cleaner pick. See our no annual fee guides. Our editorial policy explains how we describe cards.

A two-minute routine for comparing any two cards

1. Name your goal in one word: cashback, transfer, purchases or building credit.
2. Sort by that goal's key number: reward rate, 0% months plus fee, 0% purchase months, or likelihood of acceptance.
3. Take the top two or three and read only the small print above: foreign fees, revert APR, annual or monthly fee.
4. Run an eligibility check before you formally apply.

That's it. The jargon exists mostly to make near-identical cards look different. Strip it to one number and the choice gets obvious. For the general version of this process, see how to compare credit cards.
