How Do 0% Balance Transfers Work UK?
Quick Answer:
**A 0% balance transfer lets you move existing credit card debt to a new card that charges no interest for a promotional period (typically 6-29 months).** You pay a one-time transfer fee (usually 2-4% of the amount), then have the promotional period to pay off the debt interest-free. This can save hundreds in interest compared to standard credit card rates.

How Balance Transfers Work
A balance transfer moves debt from one or more credit cards to a new card with a 0% promotional rate. Here's exactly how the process works:
Apply for a Balance Transfer Card
Choose a card offering 0% on balance transfers. The promotional period typically ranges from 6-29 months. Longer periods usually have higher transfer fees.
Request the Transfer
Once approved, you provide details of the card(s) you want to transfer from (card number, amount to transfer). You can usually do this during the application or after approval.
New Card Pays Your Old Card
The new card provider pays off your old card directly (this takes 3-7 working days). You're charged a balance transfer fee (typically 2-4% of the transferred amount).
Pay Off During 0% Period
You now have the promotional period (e.g., 24 months) to pay off the balance at 0% interest. You must still make minimum monthly payments, but no interest accrues.
After 0% Period Ends
Once the promotional period ends, any remaining balance starts accruing interest at the card's standard APR (typically 20-30%). This is why it's crucial to clear the balance before the 0% period expires.
⚠️ Pro Tip: Set a calendar reminder 2 months before the 0% period ends
Fees and Costs Explained
Balance Transfer Fee
This is the main cost. You're charged a percentage of the amount you transfer, added to your new card balance immediately.
Typical Fee Structure (2024)
Fee Calculation Example
You now owe £3,090 at 0% interest instead of £3,000 at 25% APR.
Is the Fee Worth It?
Even with the fee, you save significantly on interest.
⚠️ Hidden Costs to Watch For
- •High purchase APR: The 0% usually only applies to the transferred balance, not new purchases (which might be at 25%+ APR)
- •Minimum payment: Missing a payment can void your 0% rate
- •Foreign transaction fees: 3% on overseas purchases

Real-World Example with Numbers
The Scenario
Sarah has £5,000 in credit card debt on a card charging 24.9% APR. She's paying £200/month but barely making a dent because of interest charges.
❌ Without Balance Transfer
✅ With Balance Transfer
SAVING: £1,302
And debt cleared 6 months faster
The Key to Success
Sarah calculated exactly what she needed to pay monthly to clear the balance before the 0% period ended:
Formula:
£5,150 ÷ 26 months = £198.08/month minimum
She set up a Direct Debit for £200/month and cleared the debt in full before the 0% rate expired.
Common Mistakes to Avoid
❌ Mistake 1: Continuing to Use the Old Card
After transferring the balance, many people leave their old card active and start using it again. Now you have TWO debts instead of one.
✅ DO THIS INSTEAD:
Close the old card after transfer completes, or keep it open but CUT IT UP and don't use it.
❌ Mistake 2: Only Paying the Minimum
The minimum payment (typically 1-2% of balance) won't clear the debt before the 0% period ends. You'll be left with a massive balance at 25%+ APR.
✅ DO THIS INSTEAD:
Calculate: (Balance + fee) ÷ Number of 0% months = Monthly payment needed
❌ Mistake 3: Making New Purchases on the Balance Transfer Card
New purchases are usually NOT covered by the 0% rate—they accrue interest at the standard APR (20-30%). Plus, payments go toward the balance transfer first, so purchase debt grows.
✅ DO THIS INSTEAD:
Use a separate card for purchases, or better yet, use a debit card.
❌ Mistake 4: Missing a Payment
Miss even one minimum payment and many providers will cancel your 0% rate immediately. You'll start paying 25%+ APR on the full balance.
✅ DO THIS INSTEAD:
Set up a Direct Debit for AT LEAST the minimum payment (ideally the calculated monthly amount to clear the balance).
❌ Mistake 5: Ignoring the End Date
People forget when their 0% period ends. They wake up one day to find they're being charged £100+/month in interest on the remaining balance.
✅ DO THIS INSTEAD:
Set calendar reminders at 6 months before, 3 months before, and 1 month before the 0% period ends. Consider another balance transfer if you can't clear it in time.
❌ Mistake 6: Transferring to a Card from the Same Bank
Most banks don't allow you to transfer balances between cards they issue. The application will be rejected or the transfer declined.
✅ DO THIS INSTEAD:
Always transfer to a card from a DIFFERENT bank. Check the provider before applying.
Frequently Asked Questions
Can you transfer a balance from one card to another at the same bank?
No, UK banks generally don't allow balance transfers between their own cards. You must transfer to a card from a different provider. For example, you can't transfer from a Barclaycard to another Barclaycard, but you can transfer from Barclaycard to a Virgin Money card.
How long does a balance transfer take?
Typically 3-7 working days from when you request the transfer. Until the transfer completes, you MUST continue making minimum payments on your old card to avoid late fees and credit damage. Once completed, the old card balance will show as £0.
Can you do multiple balance transfers to the same card?
Yes, you can transfer balances from multiple cards to one new balance transfer card, as long as the total doesn't exceed your credit limit. You'll pay the transfer fee on each individual transfer. This is useful for consolidating multiple debts.
What happens after the 0% period ends?
Any remaining balance starts accruing interest at the card's standard APR (typically 20-30%). Your options: (1) Pay off the remaining balance before the deadline, (2) Do another balance transfer to a new 0% card, or (3) Accept the high interest rate and pay it off as quickly as possible.
Does a balance transfer hurt your credit score?
The application causes a small, temporary dip (hard search). However, if you use the balance transfer to pay off debt faster and reduce your credit utilization ratio, your score will improve over time. The net effect is usually positive if managed responsibly.
Can I get a balance transfer card with bad credit?
Unlikely. Balance transfer cards require good-to-excellent credit (670+ score). If you have bad credit, you're better off looking at credit builder cards or a debt management plan through a charity like StepChange. Focus on improving your credit before applying for balance transfers.
🎯 Key Takeaways
Save Hundreds in Interest
A 0% balance transfer can save you £500-£1,500+ in interest charges compared to paying the standard APR.
Calculate Your Payments
Divide your total balance (+ fee) by the number of 0% months to find the monthly payment needed to clear it.
Don't Make New Purchases
New spending on balance transfer cards usually accrues interest at the standard APR—use a different card.
Set Reminders
Mark your calendar for when the 0% period ends. Plan ahead for either clearing the balance or doing another transfer.
