Capital One: credit cards, app, payments and complaints

Capital One is a credit card issuer in the UK. It lends under its own name and under the Luma brand, and it also issues the Post Office credit cards. Its cards are run through an app and online account, with a one-time passcode protecting online payments.

Capital One issues credit cards in the UK, and the name on your agreement is Capital One (Europe) plc, authorised by the Financial Conduct Authority under reference 204440, with current trading names Luma, Capital One (Europe) and Capital One¹. It was incorporated on 17 November 1999². That matters to a reader for one practical reason: it is the name to check on the FCA Register if you want to confirm who you are dealing with.

This page covers what Capital One offers, who can apply, how to run a card day to day, what happens when a payment is missed, how to dispute a transaction or complain, and where protection begins and ends.

Capital One credit cards and the brands it issues

Capital One's UK lending is credit cards. It issues cards under its own name, under the Luma brand, and as the provider of the Post Office credit cards¹. It has also issued store cards, which matters for one rule below.

The range is aimed at different credit histories rather than different rewards. A card built for people with a thin or damaged credit file typically starts with a lower credit limit and a higher interest rate than a mainstream card, and the limit can be reviewed upwards as you manage the account. The Capital One Classic is the named product page for that end of the range. For how credit cards work generally, including how interest is calculated and what a minimum payment does to a balance, see the credit cards guide.

One restriction is worth knowing before you plan anything around it. Capital One states there are no transfers between Luma, Ocean and Post Office credit cards and store cards issued by Capital One³. So a balance cannot be moved from one Capital One issued card to another. If the aim is to move a balance onto a cheaper card, that has to be a card from a different provider, and the usual questions apply: what the transfer fee is, how long any promotional rate lasts, and what the rate reverts to afterwards.

Who can apply for a Capital One card

Capital One sets its own acceptance criteria and does not publish them in the material here, so the honest answer is that eligibility is decided case by case on the application and the credit file behind it. What can be said is how lenders in this market behave.

Credit cards in the UK come from banks, finance companies and larger supermarket and store chains⁶. A card aimed at rebuilding credit is a different product from a mainstream card: the limit offered at the start tends to be smaller, and the interest rate higher, because the lender is taking more risk. Being declined elsewhere does not automatically bar an application, but a recent decline, a default or a run of missed payments will show on your file and will be weighed.

If you have a joint credit card, the main card holder is the person who should contact the card provider about it⁷. That is the practical rule for anything to do with the account, including a dispute.

Before applying, it helps to know what is on your credit file, because an application leaves a footprint. The credit scores and credit reports guide explains what lenders see and how to check it. If you are weighing up whether a card is the right kind of borrowing at all, the loans guide sets out the alternatives side by side.

Managing your card in the Capital One app and online

Day to day, a Capital One card is run through the app or the online account: checking the balance, seeing the payment due date, making a payment, and setting up or changing a one-time passcode.

The passcode is the part most people meet first. It is a unique 6-digit number that Capital One sends as a text or automated voice message to the mobile or landline number of your choice⁴. You will probably be asked for one when you pay online and see the Mastercard ID Check or Visa Secure logos⁴. When you request it, you first choose a phone number from a dropdown list showing all the numbers saved to your account, displayed with only the first digit and last 4 digits⁴. If there are additional cardholders on the account, their phone numbers are listed in that dropdown too⁴.

That last point is a small but real risk. A number you do not recognise in the list is worth querying with Capital One, because it means a number is attached to your account that you did not add.

Paying your bill and what happens if you miss a payment

A credit card bill has a due date and a minimum payment. Pay the full balance and you owe no interest on purchases; pay part of it and interest runs on what is left. The credit cards guide covers how minimum payments and interest interact.

Miss the payment entirely and the consequences build in stages. A missed payment is when you entirely fail to pay a bill⁸. Your credit card company should contact you if you miss a payment and will probably make an extra charge⁹. Extra charges are added if you miss payments¹⁰, and you get reminder letters when you miss payments¹¹. If you catch up quickly, the missed payments may not be recorded on your credit file⁸. A late payment is different from a missed one: it is recorded if a bill is paid after the due date has passed⁸.

Keep missing payments and the position hardens. You can get a default after several missed payments, anything from three to six, on your account⁸. If you miss three to six payments, the credit card company may send you a default notice⁹. A default stays on your credit file for years and affects what you can borrow and on what terms.

Help if you are struggling with repayments

Talking to a lender about difficulty is not the same as defaulting, and it does not damage your credit file. The Financial Ombudsman Service says discussing your options won't have any impact on your credit file¹². That is the single most useful thing to know if you are putting off a phone call.

What a lender can do depends on the product. For mortgages, help can include reducing your monthly payments or taking a break from your payments for a few months¹⁴. For credit cards, a company must help if you are struggling to pay back what you owe, and this can include reducing or cancelling any interest or fees if you aren't able to pay back what you owe¹⁴. Capital One's own position is that it will work with you to find a manageable solution to get yourself sorted¹⁵.

There is a limit worth stating plainly: if a debt is joint, you need to repay the full amount yourself if your partner cannot pay¹⁶. The lender is not obliged to split it.

If you are struggling with debt payments, free and confidential debt advice is available¹⁷. Where a bank has taken money from an account to cover a debt, known as the right of set off, you can contact your bank straight away and ask them to refund some or all of it if you do not have enough to cover bills and living costs or you cannot pay priority debts, and make a complaint if they do not do this¹⁶. The debt guide sets out the full range of options, and the benefits guide covers what you may be entitled to.

Fraud protection, card security and scams

The one-time passcode exists to protect you from fraud⁴. The rule that follows from that is simple and absolute: don't share an OTP, and if you get sent one that you didn't ask for, let Capital One know right away⁴. Criminals will try to trick you into sharing your one-time passcode, so treat it as carefully as you would your PIN¹⁸.

The wider habits matter as much as the code. Use strong and unique passwords and passcodes for digital wallets¹⁹, and strong and unique passwords to protect your online accounts²⁰. If you are travelling, keep your card secure and in sight, along with all your other travel documents, especially when out and about²¹.

If your card is lost or stolen, speak to your bank or building society straight away if you think your credit or debit card, online bank account or cheque book have been stolen or hacked¹⁷. Reporting quickly is what limits what you can be held liable for. Card protection insurance, sold separately, covers you if your card is lost or stolen²², though the reporting step is free and is the one that matters most.

Disputing a transaction or asking for a chargeback

If something you paid for does not arrive, or is not what was promised, there are two routes and they are not the same.

Section 75 is the statutory route, and it applies to credit card purchases. Chargeback is the scheme route. Chargeback is the route for a debit card or charge card payment, or for a credit card or buy now, pay later payment where Section 75 is unavailable⁷. Chargeback lets consumers challenge and try to recover payments made using a debit or credit card, although it only applies in certain circumstances²³.

How it works in practice: if you can provide evidence of a breach of contract, for example goods are not delivered or the service was not carried out, you can ask your card provider to attempt to recover the payment²⁴. Card issuers seek to claim back, from the merchant, the amounts you are claiming, and merchants can dispute your right to chargeback²⁵. As an illustration of scale, if a cardholder paid £1000.00, the cardholder could raise a chargeback claim for the full £1000.00 to their issuing bank²⁵.

Two limits are worth knowing before relying on it. There is not an automatic legal right to receive your money back through chargeback rights or Section 75, as this will depend on the supplier's terms and conditions, scheme rules such as Mastercard, Visa or Amex, applicable government laws and regulations and the approach taken by your card issuer²⁵. And a chargeback claim can only be made where the travel company is the one who has failed to supply you with services, not where you choose not to travel or are unable to travel²⁵.

Some banks and credit card companies offer a chargeback service, meaning they'll reverse your transaction and you'll get your money back unless the seller can successfully dispute it²⁶. But your bank or credit provider might not agree to do it²⁷. If you used a debit card or a credit card to service an online payment method such as PayPal, it is unlikely that you will be able to use either the Consumer Credit Act 1974 or the chargeback scheme to claim from your card provider²⁸. The consumer protection guide covers Section 75 in full.

Complaints: how Capital One handles them and its record

Start with Capital One. Where someone is unhappy with how an organisation handled their request, the first step is to complain to it²⁹. That gives it the chance to put things right, and a note of dates and what was said helps later.

If the complaint is not resolved to your satisfaction, the Financial Ombudsman Service is the next step. Its published complaints data records 962 total new cases for Capital One (Europe) plc in the first half of 2024⁵. For context on how that compares with the wider market, current accounts generated 7,800 new complaints in the first quarter of 2025/26³⁰, and the ombudsman's quarterly data for the first quarter of 2026/27 records 1,291 cases for First Charge Mortgage³¹. These are different products and different periods, so they are context rather than a like for like comparison.

If a complaint is about data rather than an account, a different route applies. The Information Commissioner's Office says that if you submit a complaint to it, it will handle the complaint in accordance with its complaints handling framework³². There is also a right to get your data corrected²⁹. The regulation and policy guide explains how the ombudsman and the regulator divide their work.

How your borrowing with Capital One is regulated

Credit cards are regulated borrowing. Whether a particular debt is regulated or unregulated can depend on the date it was taken out and the amount borrowed³³. Debts usually regulated by the Consumer Credit Act include store cards, store finance, personal loans, hire purchase and catalogues³³. Debts that are not regulated include mortgages, debts to family or friends, debts to unlicensed lenders or loan sharks, household bills, debts to local or central Government, some credit union loans, charge cards and some types of business debt³³.

There is a common reason an agreement falls outside: a common reason for an agreement not being regulated is if, for example, you have borrowed more than £25,000 and the agreement is for business purposes³⁴. For a consumer credit card, that is unlikely to apply.

The rules also shape how a lender must present costs. For open-end regulated credit agreements, one assumption used is that the capital is repaid by the borrower in equal monthly payments, commencing one month after the date of initial drawdown³⁵. That is the arithmetic behind an advertised APR, and it is why the APR on a card statement can look different from the rate actually paid if repayments are lumpy.

What protects you: the Consumer Credit Act, the Financial Conduct Authority's rules, the Financial Ombudsman Service, and Section 75 for credit card purchases. Where it stops: chargeback is not a legal right and depends on scheme rules and your card issuer's approach²⁵, and unregulated debts sit outside the Consumer Credit Act framework³³. If you are unsure whether a financial service has followed the rules, there is a free check available¹⁴.
