Balance transfer comparison tables can be quite confusing, so it helps to first figure out which type of offer best suits your financial situation before comparing options.

A balance transfer card lets you move existing credit card debt onto a new card, typically with an interest-free period on the transferred amount. Since no interest is charged during this period, repayments go entirely toward reducing the debt rather than servicing interest — which can mean becoming debt-free sooner than on a standard card.

0% balance transfer cards aren't all the same. Cards offering longer 0% periods usually come with a one-off transfer fee, calculated as a percentage of the amount moved. Fee-free cards exist too, but typically offer a shorter 0% period than the longest fee-charging deals.

Current market terms (as of September 2026)

Based on a review of major credit card comparison sites (including Which?, Moneyfacts, etc.) and individual provider websites, as of 01 September 2026 the longest 0% balance transfer periods on the market reach up to 38 months, at a fee of around 3.5%.

Fee-free balance transfer offers — with no upfront cost, but a shorter interest-free window — currently reach up to around 14 months.

This reflects the sources checked and may not capture every card on the market. Applicants with a weaker credit history may be offered a shorter 0% period than advertised, along with a higher representative APR. These figures change regularly — always check current offers before applying.

Providers frequently competitive in this space

When we checked in September 2026, providers including TSB, M&S Bank, Lloyds Bank, Barclaycard, MBNA, and NatWest were among those offering the longest or lowest-fee 0% purchase and balance transfer terms. Which provider currently leads the market, and by how much, changes regularly.

The Two Things That Define a Balance Transfer Offer

Every balance transfer offer comes down to two features: the fee, and the length of the interest-free period.

The transfer fee is a one-off charge, usually calculated as a percentage of the balance being moved. It ranges from 0% ("no fee") up to around 3.5% or more, and is payable once the transfer goes through. To qualify for the advertised fee, the transfer usually needs to happen within a set window after the card is approved — e.g. 30 days, though this varies by provider.

The interest-free period is the number of months during which no interest is charged on the transferred balance. This gives time to pay down the debt through regular monthly payments, without any of it going toward interest.

The two features are usually linked: a longer interest-free period typically comes with a higher fee. Shorter-duration cards — with interest-free periods up to around 20 months — can sometimes be found with no fee at all.

How Long of a Balance Transfer Do You Need?

Choosing the right balance transfer card starts with figuring out how long you'll need to clear the debt. The table below shows the months needed to pay down a balance on a 0% card, by starting balance and monthly payment. For example, a £2,000 balance paid down at £100 a month would clear in 20 months (£2,000 ÷ £100 = 20).

Narrowing Down the Field

Once you know roughly how long you'll need, compare offers with a similar 0% period and look for the lowest transfer fee available at that length. Balance transfer fees typically range from 0% to 3.5% of the transferred balance. Shorter 0% periods generally carry lower fees; longer periods generally carry higher fees, since the provider is taking on risk for longer — though pricing can vary between providers, so it's worth comparing.

Balance Transfer Trade-offs

There's no single "best" balance transfer card — the right choice depends on how long the debt will take to clear. Someone who can clear a balance within about a year may find a fee-free offer with a shorter 0% period; someone needing more than two years may find it worth paying a fee (typically 1.5–3%) for a longer 0% period.

Some sources suggest taking a fee-free card even if its 0% period is shorter than needed, on the basis that any remaining balance can be moved to another 0% card once the first period ends. This carries real risk: a change in credit profile or in the market's risk appetite could mean no new card is available when needed, and each new application leaves a mark on the applicant's credit file — usually not significant unless several applications are made in a short space of time.

A balance transfer eligibility checker can show the likelihood of acceptance for a specific card before applying, without the same credit-file impact as a full application.

Balance Transfer Credit Card Offers

If You Don't Want to Pay a Fee

Those who can clear their debt within roughly 1–1.5 years may find offers with no balance transfer fee at all, provided the transfer is made within the initial window (usually 30–60 days after acceptance). With a fee-free offer, every payment goes directly toward the balance.

If You Need More Time

Longer 0% periods — up to around 30-38 months in the current market — usually carry a one-off fee, typically around 3-3.5%. For context, the longest balance transfer periods available were around 43 months in 2017–18.)

If You Also Plan to Make New Purchases

Once past any 0% purchases period on a balance transfer card, new purchases put on the same card could have surprising repercussions. Most credit card terms specify that new purchases only remain interest-free if the entire balance — including any remaining transferred amount — is paid in full each month. If part of the transferred balance remains, new purchases will accrue interest from the transaction date, with no grace period. Using a separate card for new spending avoids this.

Balance Transfers: What to Look Out For

• The transfer must usually be completed within an initial window (often 30–60 days) to qualify for the 0% rate

• Payments must be made on time, and the credit limit must not be exceeded, to keep the 0% rate

• A weaker credit score may result in a shorter 0% period than advertised — check this before applying

Missing a payment or exceeding the credit limit typically ends the 0% period early, with interest then charged at the card's standard balance transfer rate.

How a Balance Transfer Can Help

Balance transfer cards can help manage existing debt in two ways: no interest is charged during the 0% period, and since the full monthly payment goes toward the balance rather than interest, the debt can be cleared sooner.

Making Monthly Payments on a Balance Transfer Card

A monthly payment is still required during the 0% period — a "0% balance transfer" doesn't mean nothing is owed each month, only that no interest is charged. Missing the minimum payment can end the 0% period early. Setting up an automatic payment helps avoid this.

TOP TIP: While only the minimum payment is required to keep the 0% period active, clearing the balance within that period usually requires paying more than the minimum. To work out how much, divide the transferred balance by the number of 0% months available. For example, a £1,500 balance with a 15-month 0% offer would need payments of £100 a month to clear within the period.

FAQs

What is a balance transfer fee?

A balance transfer fee is an amount you pay to transfer an existing credit card balance to a balance transfer credit card; the balance transfer fee is calculated as a percentage of the amount transferred. Balance transfer fees typically range from 0% up to 3.5% or more.

Are 0 balance transfers a good idea?

Balance transfers can be beneficial if used as part of an active debt reduction strategy - that means paying more than the minimum amount due and trying to clear your debt during the 0% promotional period. They can be harmful if used to postpone debt prepayment (e.g., you only pay the minimum due each month).

Is there a time limit for making a balance transfer?

Most balance transfer cards require the transfer to be completed within an initial window after the account is opened — often the first 30 to 60 days, though this varies by provider. This window applies to qualifying for the promotional rate; transfers made after it may not receive the 0% terms. Processing a transfer can take anywhere from a few days to a few weeks, so it's worth checking the specific window and processing time with the provider before deciding when to transfer.

Can you have more than one balance transfer credit card?

Yes, you can technically have more than one balance transfer card, but most credit card issuers won’t approve you for a second balance transfer card if you already have one with them - you’ll probably need to try a new provider. Those with higher levels of existing debt or a weak credit score may find it harder to get a second card.

How much can you transfer to a balance transfer card?

Each balance transfer credit card will have a minimum transfer amount (typically £100) and a maximum transfer amount (typically 90% to 95% of the credit limit).

Is it a good idea to transfer credit card balances?

It can be a good idea to transfer credit card balances IF you use the 0% promotional period to pay more than the minimum amount due each month to clear your existing balances. Be sure to pay on time each month and stay under the credit limit to keep the 0% promotional rate.

Is it worth it to transfer balances on credit cards?

Transferring balances on credit cards can save you lots of money in interest charges while you’re trying to clear existing credit card debt. For example, moving £1,000 from a card charging 24.9% to a 0% card would save you £305 in interest charges (assuming you make monthly payments of £50). The higher your existing interest rate, the more you can save with a balance transfer.

What does 0 apr on balance transfers mean?

0 APR on a balance transfer means you pay 0% interest for the length of the promotional period on balances transferred during an initial window (usually 30 - 60 days). Promotional periods are often in the range of 12 months to 30+ months, but can end early if you don’t follow the rules.

What's the difference between balance transfers and purchases?

Balance transfers are for existing debt and purchases card are for new spending - both can benefit from 0% promotional periods. A balance transfer is when you transfer an existing credit card balance from one credit card to another - usually from an interest charging card to a balance transfer card with a 0% promotional period. 0% on purchases means you’ll pay no interest on new purchases.

Can I transfer my credit card balance to another card?

Yes, you can transfer your credit card balance from one card to another card charging a lower interest rate, so long as balance transfers are a feature of the second card. There is a specialist market for balance transfer cards that charge 0% on transferred balances.

Can you balance transfer twice?

Yes, a balance can be transferred more than once if needed. Clearing the balance during the first 0% promotional period avoids the need for a further application. Each credit card application may leave a hard-search record on a credit report, though the impact of this can vary.

What is an ‘up to’ card?

Some balance transfer credit cards advertise ‘up to’ 0% periods. This means the full ‘up to’ length might only be offered to some applicants.

Applicants with poorer credit scorers can still get accepted for an ‘up to’ card, though they are likely to be offered a shorter 0% period than the advertised length (unless pre-approved).

What if I can’t get accepted for a balance transfer card?

If a 0% balance transfer card isn't available, specialist cards for those with poor credit scores may still offer some interest relief. There are specialist balance transfer cards out there designed for those with poor credit scores. While these cards are usually far less generous than market-leading deals, they can still give you some sort of respite on credit card debt. Using a card responsibly — staying within the credit limit and making at least the minimum repayment on time — can contribute to a stronger credit history over time. This doesn't guarantee acceptance for any other card, since each lender applies its own criteria and may assess credit report information differently.

What is the difference between balance transfer and money transfer?

A balance transfer is when you transfer an outstanding balance from one credit card to another to lock in a lower interest rate (e.g., 0%) while a money transfer is when you transfer money from your credit card to your current account.
