Carrying credit card debt is expensive — but a 0% balance transfer card lets you move existing debt to a new card and pay zero interest for an extended period. In 2026, the best balance transfer deals offer up to 29 months interest-free, giving you real breathing room to clear what you owe. Here’s how to find the right card and use it effectively.
What Is a Balance Transfer Credit Card?
A balance transfer card lets you move debt from one or more existing credit cards to a new card that charges 0% interest for a promotional period. You pay a one-off transfer fee (typically 2–4% of the balance), and then you have months — sometimes years — to pay off the debt without accruing interest.
Used correctly, this is one of the most powerful tools available to cut the cost of existing debt.

How to Choose the Right Balance Transfer Card
Consider the Total Cost, Not Just the Period
A longer 0% period sounds better, but a higher transfer fee can offset the benefit. If you can realistically clear your debt in 18 months, a card with a shorter period but lower fee may cost less overall. Calculate the fee upfront: on a £3,000 balance, a 3.45% fee costs £103.50.
Check Your Eligibility Before Applying
Most balance transfer cards use soft-search eligibility checkers, which let you see your approval chances without affecting your credit score. Always use these before making a full application. Multiple hard searches in a short period can temporarily lower your credit score.
Don’t Use the Card for New Purchases
Most balance transfer cards charge standard interest on new purchases — not the 0% rate. New spending is typically repaid last (after your transferred balance), meaning interest can accumulate quickly. Keep a separate card for new spending, or avoid using the transfer card for purchases entirely.
How Much Can You Save?
Consider this example: you have £4,000 on a credit card charging 24.9% APR. If you only make minimum payments, you could pay well over £1,500 in interest and take years to clear it. Transfer to a 0% card and pay £150/month, and you’ll clear it in around 27 months — paying only the one-off transfer fee of roughly £138.
Potential saving: over £1,300 in interest.
Steps to Transfer a Balance
- Check your existing balances — note the card providers, amounts owed, and current interest rates
- Use an eligibility checker — compare cards and check your chances without affecting your credit score
- Apply for your chosen card — you’ll typically receive a decision within minutes
- Request the balance transfer — you can usually do this during the application or shortly after in your online account. You’ll need the card number and sort code/account details of the card you’re transferring from
- Keep paying the old card — until the transfer is confirmed, continue making at least the minimum payment on your existing card to avoid late fees
- Set up a direct debit — on the new card, set up a direct debit for at least the minimum payment immediately, to avoid accidentally missing a payment (which would typically end the 0% offer)
Common Mistakes to Avoid
- Missing a payment: Even one missed payment can cancel the 0% offer and revert your balance to the standard APR
- Transferring between cards from the same banking group: You generally cannot transfer between cards issued by the same bank (e.g., Barclaycard to Barclaycard)
- Not having a repayment plan: Set a monthly payment that clears the balance before the 0% period ends
- Ignoring the end date: Diarise the end of the 0% period and consider another transfer if you still have a balance remaining
Is a Balance Transfer Right for You?
A 0% balance transfer card is ideal if you have existing credit card debt at a high interest rate and a clear plan to repay it. It’s not a solution for people who are likely to accumulate more debt — it’s a tool for people committed to clearing what they owe. If used with discipline, it can save you hundreds or thousands of pounds in interest.
