What Is A Balance Transfer Credit Card – Complete UK Guide
A balance transfer credit card is a tool designed to help you move existing credit card debt onto a new card, typically offering a 0% interest promotional period so you can repay faster without incurring additional interest charges. Widely used in the UK, these cards can be a smart way to reduce the cost of borrowing when used correctly.
If you are carrying a balance on a high-interest credit card, a balance transfer card gives you a window of time – often several months – during which no interest accrues on the transferred amount. This allows your monthly payments to go directly toward reducing the principal debt rather than being swallowed by interest.
However, balance transfers are not free. Most cards charge a one-off fee, and the terms depend heavily on your credit profile. Understanding how they work, what they cost, and which offers are worth considering is essential before you apply.
What is a Balance Transfer Credit Card?
A balance transfer credit card is a type of credit card that lets you move debt from one or more existing credit cards onto a new card. The primary advantage is that the new card often comes with a low or 0% introductory interest rate on the transferred balance, typically lasting for a set number of months.

Promotional periods range from 6 to 38 months; after that, standard APR applies.

How Does a Balance Transfer Credit Card Work?
The mechanics are straightforward but there are several important steps and conditions to understand before you apply.
Step-by-step: Initiating a balance transfer
You apply for a balance transfer card and, if approved, are given a credit limit based on affordability and a credit assessment. Once the card arrives, you activate it and then initiate the transfer – usually online or through the lender’s app – by providing the details of the card you want to move the debt from. The new lender then pays off the old card, and the transferred balance appears on your new statement.
The promotional period typically starts from account opening, but some cards require the transfer to be made within a set window, such as 60 days or 3 months, for the 0% rate to apply.
What is a balance transfer and purchase credit card?
Some cards offer a 0% period on both balance transfers and new purchases. These products can be useful if you also need to make new spending, but the 0% purchase period may be shorter than the transfer period. Be aware that many balance transfer cards charge normal interest on purchases unless a separate purchase offer is included.
If you need both a balance transfer and a new purchase card, compare the combined 0% terms carefully. Often the longest 0% periods are reserved for transfers alone.
Can I transfer a balance to a debit card?
No. Balance transfers are designed to move debt between credit cards. Transferring to a debit card is not a standard feature and is generally not possible. If you need to access cash to pay off another card, a money transfer credit card may be a different option, but that is a separate product.
What Are the Costs and Fees of a Balance Transfer?
Understanding the fees involved is crucial to deciding whether a balance transfer saves you money overall. The main costs are the transfer fee and the post-promotion interest rate.
Balance transfer fees explained
Most UK balance transfer cards charge a one-off fee of 2% to 4% of the amount transferred. For example, transferring £3,000 with a 3% fee costs £90. Some cards offer a no-fee period, typically lasting 12 months, after which a fee applies to new transfers. Longer 0% offers often come with higher fees, so you need to weigh the fee against the interest you would otherwise pay.
0% APR period – what does it mean?
During the promotional period, no interest is charged on the transferred balance. This allows your monthly payments to reduce the debt directly. However, you must still make at least the minimum monthly repayment each month. Missing a payment can cause you to lose the 0% deal and trigger interest and fees.
Hidden costs to watch out for
After the promotional period ends, any remaining balance accrues interest at the card’s standard APR, which can be 20% to 30% or more. Also, some cards charge interest on new purchases from the date of purchase, even during the 0% balance transfer period. Always read the terms carefully.
A longer 0% period may be paired with a higher transfer fee, so the cheapest card is not always the one with the longest offer. Compare both the fee and the 0% length to find the best deal for your situation.
How Long Do 0% Balance Transfer Offers Last and What Happens Next?
The length of 0% offers has grown over the years. In 2025, top deals reach up to 36–38 months, though your personal offer may be shorter depending on your credit profile.
Typical 0% offer durations (up to 38 months)
Cards such as Virgin Money and NatWest offer up to 36 months 0% on transfers made within the first 60 days or 3 months respectively. Barclaycard Platinum offers up to 31 months with a 3.45% fee. Santander’s Everyday Long-Term card gives 29 months at 0% with a 3.4% fee. MBNA offers 23 months interest-free but with a 5% fee. These examples show the range available in the market.
What to do when the promotional period ends
Once the 0% period finishes, any unpaid balance starts accruing interest at the standard APR. To avoid this, aim to clear the full debt before the deadline. If you cannot, compare the remaining balance against the card’s standard rate and consider whether another balance transfer to a new card might be worthwhile.
Can you transfer again after the 0% period?
Yes. You can apply for a new balance transfer card and move the remaining debt again, provided your credit history and income support a new application. However, each application involves a hard credit check, which can temporarily lower your score.
Timeline: What Happens When You Use a Balance Transfer Card
- Day 1–7: Apply for a card – hard credit check performed.
- Day 7–14: Card approved and received; activate card.
- Day 14–21: Initiate balance transfer (online or by phone); provide details of old card.
- Day 21–35: Transfer completes; old card balance becomes zero (or partial); new card shows transferred amount.
- After transfer: 0% period starts from card approval date; make at least minimum payments monthly.
- End of 0% period: Standard APR applies; consider another transfer or pay off balance.

| Approval depends on your credit history and income. | Future interest rates after the 0% period are variable and subject to change. |

Why Are Balance Transfer Cards So Popular in the UK?
High UK credit card interest rates, often exceeding 20%, make balance transfers highly cost-effective. Martin Lewis and MoneySavingExpert have popularised the strategy, leading to intense competition among providers. The longest 0% periods, up to 38 months, give borrowers significant time to repay debt interest-free. Regulatory changes by the FCA now require clearer disclosure of transfer fees and post-promotion rates. Combined purchase and balance transfer cards are becoming more common, though they often have lower 0% periods.

Frequently Asked Questions
What is the difference between a balance transfer and a money transfer credit card?
A balance transfer moves debt from one credit card to another. A money transfer lets you move cash from a credit card to your bank account, often with a fee and a 0% period. They serve different purposes.
Can I transfer a balance from a store card?
Yes, in most cases you can transfer a balance from a store card to a balance transfer credit card, as long as the store card is a credit card and not a charge card.
Do I need to close the old credit card after a balance transfer?
No, you can keep the old card open. Closing it may affect your credit utilisation ratio, so consider keeping it open but unused to maintain your available credit.
How long does a balance transfer take to appear on the new card?
Typically 1–2 weeks from the date you initiate the transfer. It may take up to 21 days in some cases, depending on the lenders involved.
Is it possible to transfer a balance to a family member’s card?
No, balance transfers are only allowed between credit cards in your own name. You cannot transfer a balance to someone else’s card.
What happens if I miss a payment during the 0% period?
Missing a payment can cause the 0% offer to be withdrawn, and interest will be charged on the balance from that point. Late fees may also apply.
