Eight card types cover almost everything on sale in the UK, but only one question decides which of them you should be looking at: do you clear the full statement balance every month, or do you carry it?
If you clear it, the interest rate is irrelevant to you. It could be 20% or 40% and you would never pay a penny of it. You should be picking on cashback, travel costs and purchase protection.
If you carry a balance, the reverse is true. Rewards are noise. The go-to rate and the promotional period are the only two numbers that matter, and every percentage point of cashback you chase is being wiped out several times over by interest.
Almost every bad card decision comes from answering that question wrong — usually someone who intends to clear the balance picking a rewards card, then not clearing it. The Financial Conduct Authority's Financial Lives 2024 survey found 19% of UK adults — 10.1 million people — had revolved a card balance from month to month, which is 31% of everyone who used a card or carried a balance in the previous 12 months. Intention and behaviour are different things.
Below: the decision rule, every card type and what it charges, the arithmetic on a balance transfer, and the UK-specific protection that makes a credit card worth holding even if you never borrow on it.
Which card type you should be looking at
Answer in order. Stop at the first branch that fits.
- 1. Are you behind on essential bills or unable to cover every minimum payment?Then no card is the answer. Free debt advice comes first — a new card at this point usually deepens the problem rather than solving it.
- 2. Do you already have card debt you cannot clear this month?Balance transfer card. If the debt is an overdraft or a loan rather than a card, it is a money transfer card instead.
- 3. Are you about to make a large purchase you will pay off over months?0% purchase card. Not a balance transfer card — the 0% offer on those normally does not cover new spending.
- 4. Do you have a thin or damaged credit file?Credit-builder card, used for one small recurring bill and cleared by direct debit every month.
- 5. Do you spend meaningfully abroad or online in foreign currency?A card with no non-sterling transaction fee. Check whether it also has a fee-free cash withdrawal policy — the two are separate.
- 6. None of the above, and you clear the balance every month?Cashback, rewards or air miles. Now the interest rate genuinely does not matter and you should optimise the return.
The number everything hangs on: the go-to rate
Every promotional card eventually reverts to its standard rate. That rate is the reason card debt is so hard to shift.
The Bank of England publishes a representative quoted rate on sterling credit card lending to households, and in July 2026 it stood at 24.71%. The striking thing is not how high it is but how immovable. Across the whole of 2025 and 2026 to date it has sat in a band between 24.65% and 24.71% — a range of six hundredths of a percentage point. Over the same stretch the Bank's quoted rate on a £10,000 personal loan fell from 6.71% to a low of 6.27% in February 2026, then climbed back to 6.85% by July.
Credit card rates do not move. Loan rates do.

Two things follow. There is no point holding out for cheaper card borrowing; it does not arrive. And if you have a substantial balance and a clean file, the gap between 24.71% and 6.85% is the whole argument for consolidating card debt into a fixed-term loan rather than shuffling it between cards. The Bank's own data carries a warning on that route, though: the quoted rate on a £5,000 loan in July 2026 was 12.05%, nearly double the £10,000 rate, because lenders price small loans much higher. Borrowing more than you need to reach a cheaper tier only saves money if you genuinely do not spend the extra.
Keep the scale in proportion, too. Credit cards account for £79.9 billion of the £1,969.3 billion UK households owe, so the slice of household debt charging the highest rate is also one of the smallest — which is exactly why it repays attention out of all proportion to its size.
What "representative APR" actually means
The APR in the advert is a representative APR. Under UK credit advertising rules, the lender only has to offer that rate to a majority of the people it accepts. Everyone else can be offered something higher, and you usually find out what your rate is after the application has already touched your credit file.
So: use a soft-search eligibility checker before applying, because these show your likelihood of acceptance without leaving a hard search on your file, and several hard searches in a short window read as someone hunting for credit. Then read the rate you were actually given in the welcome pack, not the one you applied for.
The same logic applies to the promotional period. "Up to 24 months at 0%" means some accepted applicants get 24 months and others get considerably less. Do not build a repayment plan on the headline length before you know your own.
The eight card types, in one table
| Card type | What it is for | How it charges you | Who should avoid it |
|---|---|---|---|
| 0% purchase | Spreading the cost of new spending over months | Nothing during the promo; go-to rate afterwards on anything left | Anyone who would spend more because it feels free |
| Balance transfer | Moving existing credit card debt somewhere cheaper | A transfer fee, charged as a percentage of the balance moved | Anyone who will keep spending on the old card |
| Money transfer | Putting cash in your current account — clears an overdraft or a private debt | A money transfer fee, usually higher than a balance transfer fee | Anyone treating it as spending money rather than debt restructuring |
| Low-interest / low APR | A lower ongoing rate with no promotional cliff edge | Interest from day one, but at a lower standard rate | Anyone who could get a 0% deal and stick to it |
| Cashback / rewards | Earning a return on spending you were doing anyway | Often an annual fee; the go-to rate if you ever carry a balance | Anyone who revolves a balance — the interest dwarfs the reward |
| Air miles | Converting spending into flights | Annual fee, plus restrictions on redemption dates and routes | Anyone who does not fly enough to burn the miles before they expire |
| Travel / no-FX | Spending abroad without the non-sterling transaction fee | Some charge an annual fee; cash withdrawals are usually still charged | Anyone using it for cash advances — those attract interest immediately |
| Credit-builder | Establishing or repairing a credit file | A high go-to rate and a low credit limit, by design | Anyone who cannot commit to a full direct debit every month |
Two products sit at the edge of the list. Store cards are credit cards branded to a single retailer, dangled with a small discount at the till and priced at the high end of the market — though less widespread than assumed: StepChange found 11% of its 2025 debt-advice clients held store card debt, against 67% holding credit card debt. Charge cards must be settled in full every statement period, with no revolving option at all.
0% purchase vs balance transfer vs money transfer
These three get confused constantly, and the confusion is expensive because each one has a different fee structure and a different job.
The three 0% products are not interchangeable
- Spreads the cost of something you are about to buy
- No upfront fee on the promotional spending
- Moves existing debt from another card
- Any balance left when the promo ends reverts to the go-to rate
- Moves an existing credit card balance somewhere cheaper
- Charges a transfer fee as a percentage of the balance moved
- New spending on the card usually sits outside the 0% offer
- Cannot normally transfer between cards from the same banking group
- Clears an overdraft, a private loan or a bill in arrears
- Money transfer fees are typically higher than balance transfer fees
- The money lands in your current account, so it is easy to spend instead
- Useful against an expensive overdraft — quoted overdraft rates run far above card rates
That last money transfer point deserves a number. The Bank of England's quoted rate on household overdrafts was 34.55% in July 2026 — well above the 24.71% card rate, a step-change that dates from the 2020 FCA overdraft reforms which banned high fixed daily charges and pushed headline rates up in their place. A money transfer card used deliberately to kill an expensive overdraft is one of the few genuinely good uses of the product. Used to fund a holiday, it is one of the worst.
The arithmetic that makes the case
Take a £3,000 balance sitting on a card at 24.71%.
Path one: pay the minimum. The Money Charity models the legal minimum as interest plus 1% of the outstanding balance. That has a neat and horrible property: the balance falls by exactly 1% a month, no matter how large it is. The first payment on £3,000 would be about £86. After three years of paying every month without fail, you would have paid roughly £2,602, of which about £1,691 was interest — and you would still owe £2,089.
Path two: transfer it. Move the £3,000 to a 0% balance transfer card with a 3% fee. The fee is £90, added to the balance, so you start at £3,090. Pay the same £86 a month — not a penny more — and the balance reaches zero in 36 months. Total cost: £3,090.
Same £86 a month, two very different outcomes
£3,000 of card debt over three years
- 0% transfer, 3% fee, £86/month fixed
- Minimum payments only at 24.71%

| 6 | £2,574 | £2,824 |

| 36 | £0 | £2,090 |
Source: Bank of England, 24.71% representative card rate, July 2026. The 3% fee and the balance are illustrative.
The point is not that transfers are free. It is that the fee is small relative to a year of interest at 24.71%, and that the real saving comes from fixing the payment. The minimum-payment path fails because the payment shrinks as the balance does. The Money Charity's own modelling makes this vivid. Taking the average credit card balance across all UK households — £2,751 in May 2026, an arithmetic average that includes the majority of households carrying no card balance at all — and paying only the legal minimum, the card would take 27 years and 10 months to clear. Fixing the payment at that same first month's £79 instead of letting it fall clears it in 4 years and 11 months. Same card, same rate, same starting payment. The only difference is that one of them stops shrinking.
Run your own balance through the credit card payoff calculator to see where your fixed payment lands you, and if you have several debts rather than one, debt snowball vs avalanche works through which order to attack them in.
What happens when the 0% period ends
This is where most people lose the gains, so run the tail explicitly.
Say the same £3,090 transfer came with 24 months at 0% rather than 36. At £86 a month you would have paid £2,064 by month 24, leaving £1,026 to revert to the go-to rate. Kept at £86 a month, that clears in about 14 further months and costs roughly £145 in interest — total 38 months and about £3,235. Worse than the clean version, still far better than doing nothing.
Two things void a promotional rate outright, and both are avoidable:
- Missing a payment. Most issuers reserve the right to withdraw the 0% offer if you miss one. Set the minimum as a direct debit even if you pay more manually, so a forgotten transfer cannot cost you the whole deal. A missed payment that hardens into a default sits on your credit report for six years from the date of default, whether or not you clear the debt.
- Spending on the transfer card. New purchases usually sit outside the promotion and attract interest immediately. Freeze the card, or better, do not carry it — cash vs card budgeting helps if temptation is the real problem rather than the rate.
Section 75: the reason to hold a UK card even if you never borrow
Most card round-ups skip this, and it is the clearest difference between a UK credit card and a debit card. Section 75 of the Consumer Credit Act 1974 makes your card issuer jointly and severally liable with the retailer for breach of contract or misrepresentation. If the sofa never arrives, the builder disappears or the airline collapses, you have a claim against your card provider as well as the trader — a legal right, not a goodwill gesture, and one that does not depend on the retailer still being solvent.
Three details that decide real claims:
- It applies even if you only paid the deposit by card. Put the deposit for a kitchen or a holiday on a credit card and the whole contract value is typically covered, not just the amount you charged.
- There is a price band. The Act sets a minimum and a maximum cash price, so very small and very large purchases fall outside it. Check the current thresholds before relying on the protection — they are statutory figures, not something your issuer sets.
- Chargeback is the fallback, not the same thing. It is a card scheme rule rather than a statutory right, works on debit cards too, and has strict time limits.
Hence the argument for holding one card purely as a payment instrument: used for big-ticket and online purchases, cleared in full by direct debit, never revolved. All of the protection, none of the cost.
Credit-builder cards, and the utilisation rule people get wrong
Credit-builder cards exist for people with thin files (new to the UK, never borrowed) or damaged ones. They come with a small limit and a rate at the top of the market, which is the point — the lender is pricing the risk, and you are never meant to carry a balance on one.
The method that works is dull and effective. Put one small recurring payment on the card — a streaming subscription or a phone bill — set a direct debit for the full statement balance rather than the minimum, and do nothing else with it for a year. That produces twelve months of on-time, in-full repayment history at essentially zero cost, which is what lenders are actually reading.
Where people go wrong is credit utilisation — the share of your available credit you are using. The "30% rule" that dominates search results is American. Experian UK's own published guidance is to keep utilisation below 25%. On a £500 credit-builder limit that means keeping the balance under £125, which a single unthinking supermarket shop can breach. It is one reason a low limit is harder to manage well than a high one.
Two more things worth knowing before you start comparing scores: the three UK bureaus run completely different scales — Experian's runs 0 to 1250, Equifax's 0 to 1000 and TransUnion's out of 710 — so the same file produces three unrelated-looking numbers, and none of them is "your credit score" in the way lenders use the phrase. Improving a bad credit rating covers what actually moves a UK file, and maximum credit score strategies covers the levers in order of impact.
When none of this is the right answer
There is a point at which choosing between card types is the wrong problem. The FCA found 5% of UK adults — 2.8 million people — in persistent credit card debt, paying more in interest, fees and charges than they paid off the balance. And 28% of StepChange's new debt-advice clients in 2025 were in a negative budget: spending more each month than they earned, even after going through the charity's full advice and budgeting process.
If your income does not cover your essentials, no card product fixes that, and a new credit line usually buys a few months at the cost of a larger problem. Free debt advice from StepChange, National Debtline or Citizens Advice is the right call, and dealing with debt in the UK walks through the options. Where the budget does balance but is tight, work out how much of your income is already committed with the debt-to-income calculator before adding anything to it.
Common questions
Does having several credit cards damage your credit score?
Holding them does not, in itself. Applying in quick succession does, because each full application leaves a hard search visible to other lenders, and several closely spaced ones read as someone urgently seeking credit. Note too that closing an old card reduces your total available credit, which pushes your utilisation ratio up.
Is a 0% purchase card better than a balance transfer card?
They do different jobs. A purchase card gives you an interest-free window on new spending; a transfer card moves existing card debt and charges a fee to do it. If you have not spent the money yet, you want a purchase card. Choose wrong and you either pay a fee you did not need or find your new spending sitting outside the promotion.
Should I pay off my credit card or my overdraft first?
Compare the rates. In July 2026 the Bank of England's quoted rate on household overdrafts was 34.55% against 24.71% on credit cards, which points at the overdraft — and a money transfer card is one route to clearing it. But rates are personal, so check what you are actually being charged, and cover every minimum payment before directing extra money anywhere.
Do rewards cards make sense if I carry a balance?
Almost never. At a go-to rate near 24.71%, a balance carried for a full year costs roughly £25 for every £100 of it, while cashback returns a small fraction of that. If you are revolving, the rate is the only lever with real money attached — compound interest explained shows why the mechanism that builds savings works just as hard against you here.
The one-line version
Answer the clearing question honestly, pick from the branch it lands you on, fix the payment rather than letting it fall, and put big purchases on a credit card for Section 75 even if you settle in full the same month.
