The average UK credit card charges around 35.8% APR in 2026 (Moneyfacts). Moving £3,000 of debt to a 0% balance transfer card for 24 months can save £600–£900 in interest — more than enough to cover any transfer fee.

★ EDITOR'S VERDICT For most people carrying credit card debt in 2026: TSB Platinum (38 months, 3.49% fee) gives the most time to clear your balance. If you can clear the balance in 14 months, Barclaycard Platinum fee-free saves the transfer fee entirely. For the lowest total cost on a large balance, MBNA at 2.99% fee undercuts everyone on fee while still offering 35 months. Always use an eligibility checker before applying — a rejected application triggers a hard credit search. |
How to use a balance transfer card correctly
- Check eligibility first — use MoneySavingExpert Credit Club or ClearScore (soft search, no credit impact).
- Apply for one card only — multiple applications in a short period harm your credit score.
- Transfer within the deadline — most cards require the transfer within 60–90 days of opening. Miss this and you lose the 0% offer.
- Set a direct debit — calculate monthly payment needed to clear the full balance before the 0% ends. Set it up on day one.
- Do not use the card for new purchases — new spending often goes on a different (higher) rate and complicates repayment.
- Set a diary reminder 2 months before expiry — to either clear the remaining balance or transfer again.
How balance transfers work
A 0% balance transfer card lets you move existing credit card debt to a new card and pay no interest for a set period. A one-off transfer fee (typically 2–3.5% of the amount transferred) is charged upfront — this is added to your balance on the new card. After the 0% period ends, any remaining balance reverts to the standard APR (typically 24.9%).
You cannot transfer a balance between cards from the same banking group. The transfer is made directly by the new card — you give them your old card details, and they pay it off on your behalf.
Eligibility and what lenders look for
Balance transfer cards from major providers are generally aimed at borrowers with a good to excellent credit profile. Lenders check your credit score, income, and existing debt levels. If you have missed payments, CCJs, or a thin credit file, you may be offered a shorter 0% period or a higher transfer fee than the headline rate — or declined entirely. Use an eligibility checker before applying to assess your chances without a hard credit search.
FCA regulation and your rights
All UK credit card providers are authorised and regulated by the Financial Conduct Authority (FCA). Under the Consumer Credit Act 1974, you have the right to complain to the Financial Ombudsman Service if your complaint is not resolved by the provider.
Frequently asked questions
How does a balance transfer credit card work?
You apply for a new card, provide details of your existing credit card debt, and the new card pays off your old card directly. A one-off transfer fee (typically 2–3.5%) is added to your new balance. The transferred amount then sits at 0% interest for the agreed period — giving you time to clear the debt without interest accumulating. Any remaining balance after the 0% period reverts to the standard APR (typically 24.9%).
What is the longest 0% balance transfer period in the UK right now?
As of May 2026, the longest 0% balance transfer period available in the UK is 38 months, offered by TSB Platinum Balance Transfer Card with a 3.49% transfer fee. Barclaycard Platinum and NatWest both offer 36 months. If you can repay within 14 months, Barclaycard Platinum also offers a fee-free 14-month option.
Is a balance transfer fee worth paying?
Almost always yes, if you are paying interest on your existing card. On a £3,000 balance at 22% APR, you pay approximately £660 in interest per year. A 3% transfer fee on £3,000 is £90 — a one-off cost versus ongoing interest savings. The fee is only not worth it if you can clear the balance very quickly (within 1–2 months) or if a no-fee card has a long enough 0% period for your repayment plan.
Can I transfer a balance from the same bank?
No. You cannot transfer a balance between two cards issued by the same banking group. For example, you cannot transfer from a Barclaycard to another Barclaycard, or from a Halifax card to a Lloyds card (same group). You must transfer to a card from a different banking group.
What happens if I do not pay off the balance before the 0% period ends?
Any remaining balance reverts to the standard APR — typically 24.9% on most balance transfer cards. Set a monthly direct debit for the exact amount needed to clear the full balance before the 0% period ends. Divide your total balance by the number of months in the offer to calculate the required monthly payment.
Will a balance transfer affect my credit score?
Applying for any credit card involves a hard search, which can temporarily reduce your credit score by a small amount. The balance transfer itself does not harm your score — in fact, if it reduces your overall credit utilisation by clearing a high-balance card, it can improve your score over time. Use an eligibility checker (soft search) before applying to confirm likely acceptance.
