Understanding credit cards in the UK

What is a credit card and how does it work?

A credit card lets you borrow money up to a set limit to make purchases or withdraw cash. Unlike a debit card that uses money from your bank account, a credit card creates a debt that you repay later. Each month, you'll receive a statement showing your balance, minimum payment due, and payment deadline.

When you use your card, the credit card company pays the merchant on your behalf. You then owe that money back to the card provider. If you pay your full balance by the due date, you typically won't pay any interest. However, if you only make the minimum payment or pay less than the full amount, interest charges apply to the remaining balance.

Benefits of credit cards: why get a credit card in the UK?

Credit cards can offer several advantages that may make them useful financial tools:

• Consumer protection: Section 75 of the Consumer Credit Act provides protection for purchases between £100 and £30,000, making you and the card company jointly liable if something goes wrong with your purchase.

• Building credit history: Regular, on-time payments help demonstrate responsible borrowing and may improve your credit score over time.

• Payment flexibility: You can spread the cost of larger purchases over several months, though interest may apply if you don't pay in full.

• Rewards and cashback: Many cards offer points, cashback, or other rewards for spending, which can effectively give you money back on purchases you'd make anyway.

• Emergency access to funds: Credit cards can provide a financial safety net for unexpected expenses when you don't have immediate cash available.

Should I get a credit card in the UK? Pros and cons

Top reasons to consider a credit card in the UK

Getting a credit card could suit you if you want to:

• Help build your credit score by demonstrating responsible borrowing habits

• Access consumer protection for online shopping and larger purchases

• Earn rewards on spending you're already doing

• Have emergency funds available when needed

• Spread the cost of essential purchases over time

• Improve your financial flexibility for managing monthly cash flow

Common risks and how to manage credit card debt

Credit cards do carry risks that it's worth understanding:

• High interest rates: Average credit card APRs in the UK are typically in the 24-27% range, which can make debt expensive if it isn't repaid promptly.

• Debt accumulation: Easy access to credit can lead to overspending if you're not careful with budgeting.

• Credit score impact: Late payments or high balances relative to your limit could affect your credit score.

• Fees: Annual fees, cash advance charges, and foreign transaction fees can add up.

To help avoid these pitfalls, consider paying your full balance each month, keeping spending well below your credit limit (many experts suggest below 30%), and setting up direct debits so you don't miss payments.

How many credit cards should I have in the UK?

There's no single right number of credit cards. Some people manage well with just one card, while others find it useful to have several for different purposes. It can help to consider these factors:

• Your ability to manage multiple payments without missing due dates

• Whether you can resist the temptation to overspend with more available credit

• The benefits each card offers and whether they justify having multiple cards

• Your overall credit utilisation across all cards combined

Many financial commentators suggest starting with one card and only adding others once you've shown you can manage credit responsibly.

Types of credit cards available in the UK

0% interest credit cards and introductory offers

Zero percent interest cards offer a promotional period where you pay no interest on purchases, balance transfers, or both. These deals typically last 6 to 34 months, depending on the card type and lender.

Balance transfer credit card options in the UK

Balance transfer cards let you move existing debt from other cards, which can help you take advantage of lower interest rates or 0% promotional periods. This may help you save money on interest while paying down debt.

Typical features:

• 0% interest periods of 6 to 34 months, depending on the card type and lender

• Balance transfer fees that typically range from around 1.5% to 3.8%, depending on the card and promotional offer

If you have limited credit history or past credit difficulties, credit builder cards are designed to help you demonstrate responsible borrowing. These typically have:

• Lower credit limits initially

• Higher APRs than standard cards

• Potential for limit increases with a good payment history

• Reporting to credit reference agencies, which can help build your credit file

Credit card guide: managing your card responsibly

Making payments and avoiding interest charges

Smart payment habits can help you avoid expensive interest charges:

• Pay in full each month to help avoid interest entirely

• Set up direct debits for at least the minimum payment to help avoid late fees

• Pay more than the minimum if you can't pay in full, as this can reduce interest faster

• Make payments early, which can improve your payment history and available credit

Balance transfers and 0% periods: how to use them

To get the most from balance transfers, you could:

• Calculate total costs, including transfer fees and any interest after promotional periods

• Create a payoff plan to clear the balance before rates increase

• Avoid spending on the new card unless it offers 0% on purchases too

• Think carefully before closing old accounts, as this can affect your credit utilisation ratio

Making the most of cashback and rewards on UK cards

You can often get more from rewards cards by:

• Using the card for spending categories that earn the highest rewards

• Paying balances in full, so interest doesn't exceed rewards earned

• Understanding redemption options and choosing the most valuable ones

• Tracking spending to make sure you're meeting any bonus requirements

• Reviewing your card annually to check it still suits your needs

Frequently asked questions

What credit score do I need for a credit card in the UK?

Credit score requirements vary by card type and lender. Credit builder cards may accept applicants with lower scores or limited histories, while premium cards typically require a stronger overall credit profile. Checking your score with ClearScore first can help you understand which cards you may qualify for.

How long does it take to get approved for a credit card in the UK?

Many credit card applications receive instant decisions online. If additional verification is needed, you may wait around 7 to 10 working days. Once approved, your card typically arrives within around 5 to 7 working days by post.

Can I get a credit card with bad credit in the UK?

There are credit builder cards designed for people with limited or impaired credit history. These cards typically have higher APRs and lower credit limits initially, but they report to credit agencies, which can help you build your score over time.

What happens if I miss a credit card payment?

Missing a payment can result in late fees, potential changes to your APR, and negative information on your credit report. If you're more than 30 days late, this is likely to be reported to credit agencies and may lower your credit score. Setting up direct debits can help you avoid missed payments.

How does ClearScore help with credit card applications?

ClearScore shows you credit cards you may be pre-approved for without affecting your credit score. This can help you avoid rejections that might affect your credit rating, and means you're applying for cards you're more likely to be accepted for. Pre-approval doesn't always guarantee acceptance and is subject to lenders' checks of your credit status.

Should I close old credit cards I don't use anymore?

Generally, keeping old cards open may help your credit score by maintaining the length of your credit history and keeping your overall credit utilisation ratio lower. However, if the card has annual fees or you're tempted to overspend, closing it might be the better option for your situation.

What's the difference between APR and interest rate on credit cards?

APR (Annual Percentage Rate) is the standardised figure that reflects the cost of borrowing over a year, including the interest rate plus certain fees. The interest rate alone refers only to the cost of borrowing the money, without other charges factored in.
