Credit Card vs Debit Card: Which Is Safer and When to Use Each (UK)

By QuidRadar Team · Updated 30 October 2026

A debit card spends money that's already in your bank account. A credit card lets you borrow up to a limit and pay it back later. Both are accepted almost everywhere, but they work differently when something goes wrong, when you travel, and for your credit score.

Key takeaways - Credit cards usually give stronger protection. Section 75 can make the card provider jointly liable for purchases of £100 to £30,000. - Debit cards don't have Section 75, but you can ask your bank for a chargeback. - With fraud, a credit card means the bank's money is at risk, not yours, while it's investigated. - Credit cards can help build your credit history, but only if you pay on time. - Debit cards are simpler and avoid interest, so they're better if you might not clear a credit card bill in full.

The main differences

Protection when things go wrong

Section 75

Under section 75 of the Consumer Credit Act 1974, if you buy something costing more than £100 and up to £30,000 with a credit card, the card provider is jointly liable with the seller if there's a breach of contract or misrepresentation. If the company goes bust or doesn't deliver, you can claim from your card provider. This applies even if you paid only part of the cost on the card. Full details: Section 75 Explained: Your Credit Card Purchase Protection.

Chargeback

Chargeback isn't a law. It's a process run by the card schemes, such as Visa and Mastercard. MoneyHelper explains that it can help you get money back from the seller's bank if goods don't arrive or are faulty, on both debit and credit cards. There's no minimum spend, but there are time limits, often 120 days, and it's not a legal right.

Fraud

If someone uses your card details without permission, the FCA says your bank or card provider should generally refund you, unless it can show you acted fraudulently or with gross negligence. The difference is whose money is missing in the meantime. With a debit card, money leaves your account straight away, which can affect bills while it's sorted out. With a credit card, it's the lender's money. See Credit Card Fraud: What to Do If Your Card Is Used Without Permission (UK).

Costs

A debit card is usually free to use in the UK. A credit card can be free too, as long as you pay your statement in full by the due date every month. If you don't, interest is charged at the card's rate, which can be around 25% APR or higher on mainstream cards. See How Is Credit Card Interest Calculated? A Simple UK Guide.

Using a credit card to withdraw cash is usually expensive. Most cards charge a fee and interest from the day you withdraw. Use a debit card for cash. See Credit Card Cash Withdrawals: Fees, Interest and Using ATMs Abroad.

Credit score

Using a credit card and repaying it on time shows lenders you can manage credit, which can help your credit score. Keeping your balance low compared with your limit helps too. Experian explains that a lower credit utilisation is generally better. See Credit Utilisation Explained: How Much of Your Limit Should You Use?.

Debit card spending doesn't usually appear on your credit file, so it won't help or harm your score, though an arranged overdraft does show up.

Which to use, and when

Using a credit card like a debit card

Many people get the best of both by using a credit card for everyday spending, then paying off the full balance each month by Direct Debit. You get Section 75 protection, possible rewards and a stronger credit history, without paying interest. This only works if you treat the credit limit as money you don't have. Track your spending and don't spend more than you would with a debit card.

What about Buy Now Pay Later?

Buy Now Pay Later has different protections again. See Buy Now Pay Later vs Credit Card: Costs, Protection and the 2026 Rules.

Hire cars, hotels and deposits

Car hire firms and hotels often take a pre-authorisation, or "hold", on your card when you arrive. On a debit card, that money is taken from your available balance and can take several days to be released. On a credit card, it only reduces your available credit. Some hire firms also insist on a credit card in the main driver's name, so check before you travel.

Frequently asked questions

Is it safer to use a credit card or a debit card?

Credit cards usually offer more protection, thanks to Section 75 on purchases from £100 to £30,000. They also mean the lender's money, not yours, is at risk if there's fraud.

Does Section 75 apply to debit cards?

No. Debit cards don't have Section 75 protection, but you can ask your bank for a chargeback.

Does using a debit card build credit?

Not usually. Debit card spending isn't normally reported to credit reference agencies.

Should I use a credit card for everyday spending?

It can make sense if you pay the full balance every month. If you might not, a debit card avoids interest.

Which card should I use abroad?

A card with no foreign transaction fee. For larger bookings, a credit card adds protection.
