0% Purchase vs Balance Transfer Card: Which Do You Need?

By QuidRadar Team · Updated 30 October 2026

Both types of card offer a period without interest, but on different things. A 0% purchase card lets you spend now and pay back over time without interest. A balance transfer card lets you move debt you already have from another card and pay it off without interest. Picking the wrong one can mean paying interest you didn't expect.

Key takeaways - New spending you want to spread out? Look at a 0% purchase card. - Existing card debt costing you interest? Look at a balance transfer card. - Both? A combined card offers 0% on both, often with slightly shorter periods for each. - Balance transfers usually cost a one-off fee of around 0% to 3.5%. 0% purchase offers usually don't. - On a balance transfer-only card, new purchases may be charged interest at the standard rate.

The key differences

0% purchase card Balance transfer card
0% applies to New spending on the card Debt moved from another card
Up-front fee Usually none Usually a transfer fee (some are fee-free)
Typical longest periods (our data, Oct 2026) Up to about 26 months Up to about 38 months
Main risk Overspending, then interest when the deal ends Running up new debt on the old card

When a 0% purchase card makes sense

A 0% purchase card can help you spread a big, planned cost, such as a new boiler, furniture or a wedding, over several months without interest. It also gives you Section 75 protection on purchases between £100 and £30,000.

Longest 0% purchase offers we found on 30 October 2026: - TSB Platinum Purchase: up to 26 months. - M&S Purchase Plus: up to 26 months. - Lloyds Bank Large Purchase: up to 25 months. - HSBC Purchase Plus: up to 24 months.

Plan your payments. Divide the total you'll spend by the number of 0% months, and pay at least that each month. If you only make the minimum payment, you could still owe a large balance when the 0% period ends.

When a balance transfer card makes sense

If you're paying interest on existing card debt, a balance transfer moves it to a new card with 0% interest for a set time. You'll usually pay a fee, added to the balance. Most of the long deals we list charged about 3% to 3.5%, but there are fee-free deals of around 11 to 12 months.

Examples when we checked: - TSB Platinum Balance Transfer: up to 38 months, 3.49% fee. - Nationwide Balance Transfer: 30 months, 2.99% fee. - Barclaycard Platinum No Fee: up to 12 months, no fee.

Combined cards: 0% on both

Some cards offer 0% on both purchases and balance transfers. These suit you if you want to move a balance and also have a planned purchase coming up. Examples from our October 2026 data:

Card 0% purchases 0% balance transfers Transfer fee
NatWest Purchase and Balance Transfer Up to 23 months Up to 21 months 3.49%
Barclaycard Platinum 22 month purchase & 19 month BT Up to 22 months Up to 19 months 3.45%
Tesco Bank Balance Transfer and Purchases 21 months 21 months 2.95%
Virgin Money All Round Up to 20 months Up to 20 months 2.95%
Santander All in One 15 months 15 months 0% (£3 monthly fee)
Nationwide Purchase and Balance Transfer 15 months 15 months 2.99%

The two periods can end at different times. Make a note of both dates.

The trap with balance transfer-only cards

Many long balance transfer cards offer only a short 0% period on purchases, often around 3 months. After that, any new spending is charged at the standard rate. Payments you make might go towards the cheapest debt first, while any amount above the minimum is usually put towards the highest-interest balance. That's a rule card issuers have to follow, but it can still mean interest builds up on new spending.

Simple rule: if you use a card for a balance transfer, try not to spend on it. Use a different card or your debit card for everyday spending.

Which one should you choose?

  • You have no card debt and a big purchase coming up: a 0% purchase card.
  • You have card debt and no plans to spend: a balance transfer card. Compare fees and periods.
  • You have both: a combined card, or a balance transfer card plus careful spending elsewhere.
  • You want to borrow a fixed amount with a set end date: you could also compare a personal loan. See Balance Transfer vs Personal Loan: Which Is Better for Clearing Debt?.

What happens when the 0% ends?

Whatever is left starts to be charged at the card's standard rate, which is often around 25% APR on mainstream cards. Clear it before then if you can. See What Happens When Your 0% Credit Card Deal Ends?.

Check your eligibility first

Both types of card are usually aimed at people with a good credit history. The longest deals often say "up to", which means some people are offered a shorter period. An eligibility checker uses a soft search, which doesn't affect your credit score, so it's a sensible first step: Credit card eligibility checkers explained.

Frequently asked questions

What's the difference between a 0% purchase and a balance transfer card?

A 0% purchase card charges no interest on new spending for a set time. A balance transfer card charges no interest on debt moved from another card, usually for a fee.

Can I use a balance transfer card for shopping?

You can, but purchases are often only at 0% for a short time, or not at all. After that, the standard rate applies.

Is there a card with 0% on both purchases and balance transfers?

Yes. Several cards we list offer both. The periods can be different for each, so check both end dates.

Do 0% purchase cards charge a fee?

Usually not for purchases. Fees can still apply for cash withdrawals, late payments and using the card abroad.

Which is better for my credit score?

Neither is better in itself. What matters most is paying on time and keeping your balances under control.
