Credit Cards Explained

The four main types of UK credit card, what they are good for, and the traps to check before applying.

Balance Transfer Cards

Move existing card debt to a new card charging 0% interest for a promotional period. You usually pay a one-off transfer fee (often 1–3% of the balance).

What to check

  • The transfer fee — a longer 0% period often means a higher fee
  • The revert rate you will pay once the 0% period ends
  • Whether transfers must happen within a set window (often 60–90 days)
0% Purchase Cards

Spread the cost of new spending interest-free for a fixed period. Useful for a planned purchase you can repay before the offer ends.

What to check

  • The length of the 0% window versus how fast you can repay
  • Missing a payment can void the promotional rate
  • The standard APR applied after the offer ends
Cashback & Rewards Cards

Earn a percentage of your spending back as cash, points or vouchers. Introductory cashback rates are often higher for the first few months.

What to check

  • Cashback caps and tiered earning rates
  • Annual fees that can wipe out the rewards
  • Only worthwhile if you clear the balance in full each month
Credit-Builder Cards

Designed for thin or damaged credit files. Limits are low and APRs are high, but used carefully they can rebuild your score over 6–12 months.

What to check

  • APRs are typically 30%+ — always repay in full
  • Small starting limits; avoid using more than ~30% of it
  • Check the provider reports to all three credit reference agencies

Before you apply

Deeper dives: how balance transfer cards work and how to build your credit score.

  • Use an eligibility checker first — it is a soft search and will not affect your credit file.
  • The advertised “representative APR” only has to be offered to 51% of accepted applicants — you may be offered more.
  • Compare deals on the provider’s own site and on FCA-authorised comparison services before deciding.
