Is a 0% balance transfer card worth the fee? Compare the transfer fee against interest avoided and find the net saving — plus whether you'll clear the balance in time.
A balance transfer lets you move existing credit card debt to a new card with a lower (often 0%) promotional interest rate. During the 0% period, every penny you pay reduces the principal balance — not interest. This makes it far easier to clear debt quickly.
UK balance transfer deals typically last 12–30 months with fees of 0–3% of the amount transferred. The fee is added to the balance on the new card. Most deals require you to have a credit score that qualifies for the card.
| 0% Period | Typical Fee | Best For |
|---|---|---|
| 12 months | 0–1% | Small balances you can clear quickly |
| 18–20 months | 1.5–2.5% | Medium balances with disciplined repayments |
| 24–28 months | 2.5–3% | Larger balances needing more time |
| 29–30 months | 3–3.5% | Large balances, lower monthly payments |
In almost all cases, yes. A typical 3% fee on a £3,000 balance costs £90. At 24.9% APR, you'd pay £747 in interest in one year alone. Even on a 12-month 0% deal, the saving is approximately £657 net. The only time a fee may not be worth it is if you can clear the full balance in a very short time at your current rate.
The best balance transfer deals in the UK in 2026 typically offer 0% for 24–30 months with fees of 2–3%. Cards from Barclaycard, Virgin Money, MBNA, Halifax, and NatWest regularly feature in best-buy tables. The 'best' deal depends on your needs: if you can repay quickly, choose a card with a low fee; if you need longer, prioritise a longer 0% window.
When the promotional period ends, any remaining balance reverts to the card's standard purchase or transfer rate, typically 20–30% APR. Set a calendar reminder 2 months before the deal expires and arrange another balance transfer or clear the balance. Our calculator shows the interest you'd pay if a remaining balance reverts to 21.9% APR.
To clear the balance during the 0% period, divide the total transferred balance (including the transfer fee) by the number of months in the deal. For example, if you transfer £3,000 with a 3% fee (total £3,090) on a 24-month deal, you need to pay £128.75 per month. Always pay at least this amount — minimum payments will not clear the balance in time.
Generally, no — it is strongly advised not to spend on a balance transfer card. New purchases are usually charged at the standard purchase rate (20–30% APR), not the 0% transfer rate. Monthly payments are typically applied to the cheapest balance first, meaning your new spending can accumulate interest while you only pay down the 0% balance.
Applying for a balance transfer card involves a hard credit search, which temporarily reduces your score by a few points. However, reducing your credit utilisation and making on-time payments will improve your score over time. The net effect is usually positive within 3–6 months if you manage the card well.
Most UK balance transfer cards have a minimum transfer amount of £100. Even very small balances can benefit from a transfer — the saving at 24.9% APR over 12 months is £124.50 on a £500 balance, which exceeds a typical 3% fee of £15.
Yes, most 0% balance transfer cards accept transfers from store cards as well as credit cards. Store cards typically charge very high APRs (30–40%), making them ideal candidates for a balance transfer. You generally cannot transfer a balance between two cards from the same bank group.
The longest 0% balance transfer deals are typically available to applicants with good to excellent credit scores. Applicants with fair credit may be approved for shorter deals or lower credit limits. Always use an eligibility checker (soft search) before applying to see your approval chances without affecting your credit score.
UK balance transfers typically take 3–7 working days to complete once your new card is approved and you've requested the transfer. During this time, continue to make minimum payments on your existing card to avoid missed payment fees. Some cards complete transfers in as little as 1–2 working days.
Yes, if your existing card offers a promotional 0% balance transfer rate for existing customers, you may be able to do an internal transfer. However, these deals are less common than those for new customers. Typically, the best 0% offers are reserved for new account holders.
A balance transfer moves debt directly between credit cards. A money transfer sends credit card funds into your bank account, which you can then use to pay off an overdraft or any other debt. Money transfer fees are slightly higher (typically 3–4%) but are useful for paying non-card debt. Both types benefit from 0% promotional periods on specialist cards.
