0% credit cards explained: interest-free spending and transfers

Quick answer: 0% credit cards offer a promotional period during which you pay no interest on purchases, balance transfers, or both. They are powerful tools for planned borrowing or debt reduction — but only if you clear the balance before the promo ends.
0% credit cards are among the most useful financial products in the UK when used correctly. They let you spread the cost of purchases or move expensive debt to an interest-free period lasting 12 to 28 months. The danger is treating the 0% period as permanent — when it ends, standard APRs of 20% or more kick in on any remaining balance.

Types of 0% cards
Purchase cards: interest-free on new spending. Ideal for planned large purchases you can repay within the promo period.
Balance transfer cards: move existing credit card debt to 0%. Best for clearing high-interest card balances systematically.
Money transfer cards: transfer 0% funds to your bank account. Useful for paying off expensive overdrafts or personal loans.
Using 0% cards effectively
Divide your balance by the number of months in the promo period and set up a direct debit for that amount. On a £3,000 balance with 24 months at 0%, pay £125 per month.
Do not spend on a balance transfer card unless it also offers 0% on purchases — new spending is usually charged at the standard rate.
When the 0% period ends
Any remaining balance is charged at the card's standard APR — often 20–25%. Mark the end date and plan to clear the debt or transfer again.
Repeated applications for new 0% cards leave hard searches on your file. Focus on reducing the underlying debt rather than perpetually transferring.
Common questions
Can I get a 0% card with bad credit?
Unlikely for the longest 0% periods. Some specialist cards offer shorter 0% periods for people rebuilding credit, but rates after the promo are high.
Should I pay the minimum on a 0% card?
You must pay at least the minimum to keep the 0% rate, but paying only the minimum will not clear the debt before the promo ends. Pay as much as you can.
Is a 0% card better than a personal loan?
For short-term borrowing under £5,000 that you can repay within the promo period, 0% cards are usually cheaper. For larger amounts or longer terms, a fixed-rate loan offers more certainty.
