A balance transfer credit card lets you move existing credit card debt to a new card offering 0% interest for a set period. During this time, all your payments reduce the balance rather than paying interest. The best balance transfer cards currently offer 0% periods of up to 28 to 30 months — giving you over two years to clear debt interest-free.
Balance transfer cards offer 0% interest for a set period. You pay a one-off transfer fee (typically 2 to 3.5%) but save on interest. On a £3,000 balance at 22% APR, a 12-month 0% deal saves approximately £660 in interest.

How does a balance transfer work?
Step 1 — Apply for the balance transfer card; tell the new provider the account(s) you want to transfer from and the amounts
Step 2 — If approved, the new card pays off your old balance(s) and transfers the debt to the new card
Step 3 — You pay a one-off transfer fee (e.g. 2.99% of the amount transferred)
Step 4 — You have the 0% period (e.g. 28 months) to repay the balance interest-free
Step 5 — After the 0% period, any remaining balance attracts the standard APR — aim to clear before this

Key rules to make a balance transfer work
Set up a direct debit to make at least the minimum payment each month — missing a payment can end the 0% deal
Calculate a monthly repayment to clear the full balance before the 0% period ends
Do not use the balance transfer card for new spending — new purchases often attract the full APR immediately
Do not apply for more credit in the months before or after; multiple applications harm your credit score
If you cannot clear the balance in time, consider a second balance transfer to a new 0% card
Verdict
Barclaycard Platinum for the longest 0% period
For the longest debt-clearing runway, Barclaycard Platinum offers up to 30 months at 0%. Calculate your monthly repayment: £3,000 debt over 28 months = £107/month. Set this as a direct debit and you will be debt-free before interest kicks in.
Frequently asked questions
Does a balance transfer affect my credit score?
Applying for a balance transfer card involves a hard credit search — a small temporary dip. If approved, your credit utilisation may fall (as you have more available credit), which can improve your score over time. Always check eligibility using a soft-search tool before applying.
Can I balance transfer to a card I already have?
No. You cannot transfer a balance from a card to another card issued by the same banking group. For example, you cannot transfer a Halifax balance to a Lloyds card (both are Lloyds Banking Group).
What happens if I do not clear the balance before the 0% period ends?
Any remaining balance attracts the standard APR (typically 22 to 25%). You can either continue paying at this rate, or apply for another 0% balance transfer card to move the remaining debt.
Is there a limit on how much I can balance transfer?
Yes. The maximum balance transfer is limited to your credit limit on the new card, minus any transfer fee. Cards typically allow you to transfer up to 90 to 95% of the credit limit. Credit limits are set by the lender based on your creditworthiness.
