What is the main difference between a credit card and a debit card?

A debit card spends your own money directly from your bank account. A credit card borrows money from the card issuer, which you repay later. With a debit card, the money leaves your account immediately. With a credit card, you receive a statement and have time to pay.

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

Credit cards are generally safer for online purchases. They offer Section 75 legal protection for purchases £100-£30,000, easier fraud resolution (you dispute borrowed money, not your own), and chargeback rights. If your card details are stolen, credit cards typically offer better protection and faster resolution.

Should I use credit or debit for everyday purchases?

If you can pay your credit card balance in full each month, using a credit card for everyday purchases can be beneficial — you get purchase protection, potential cashback/rewards, and build credit history. If you struggle to control spending or might not pay in full, stick to debit to avoid interest charges.

Credit Card vs Debit Card UK — What's the Difference? | PocketWise

Credit cards and debit cards look similar but work very differently. Understanding when to use each can save you money and protect your purchases.

Key Differences

Feature	Credit Card	Debit Card
Whose money	Bank’s (borrowed)	Yours
When you pay	Later (statement)	Immediately
Interest charged?	Yes, if not paid in full	No
Credit limit	Yes	Limited by your balance
Builds credit	Yes	Usually no
Section 75 protection	Yes (£100-£30,000)	No
Chargeback	Yes	Yes (but weaker)

How Each Works

Debit Card

Aspect	How It Works
Spending	Money leaves your account immediately (or within hours)
Overdraft	May go overdrawn if you spend more than you have
Interest	No interest (but overdraft fees if applicable)
Account type	Linked to current account

Credit Card

Aspect	How It Works
Spending	Borrowed from card issuer up to credit limit
Statement	Monthly bill shows what you owe
Payment	Pay by due date; full balance = no interest
Interest	Charged if you don’t pay in full (~20-30% APR)

Purchase Protection Comparison

Section 75 (Credit Cards Only)

Feature	Detail
What it covers	Purchases £100–£30,000
Who’s liable	Card issuer equally liable with seller
What’s protected	Faulty goods, non-delivery, company goes bust
Cost	Free — it’s the law
Example	Book £2,000 holiday, company fails = claim full amount from card issuer

Chargeback (Both Cards)

Feature	Debit Card	Credit Card
Available	Yes	Yes
Legal right?	No — card scheme rules	No — card scheme rules
Time limit	Usually 120 days	Usually 120 days
What’s covered	Non-delivery, faulty goods	Non-delivery, faulty goods
Strength	Weaker	Stronger (plus Section 75 backup)

Key point: For purchases £100+, credit cards give you both Section 75 AND chargeback. Debit cards only give chargeback.
