The best 0% balance-transfer credit cards

Balance transfer credit cards can slash the costs of existing credit card debt. So using one can be a sensible financial decision that could save you hundreds of pounds in interest payments.

The latest Bank of England data shows that quoted interest rates on credit cards reached an average of 21.66% over the summer. That means that for every £1,000 borrowed, an average cardholder will have to pay £216.66 in interest a year if the debt is not paid off (most credit cards don’t charge interest if you pay off the balance every month). 

For borrowers who are finding it hard to keep up with repayments, switching credit card balances onto a balance transfer credit card with a zero per cent interest rate makes good sense.

You could get as much as 34 months of 0% interest, though the actual deal you get will depend on your credit score.

The best balance transfer credit cards on the market 

To avoid paying any interest, users of balance transfer credit cards need to make the minimum repayment each month and also repay the debt within the interest-free period. 

It’s also important that you only use the card to pay off the existing credit card debt – and not spend on the card – or you could face hefty interest charges. Not paying the minimum balance each month could also incur fines and damage your credit rating.

You will need a good credit score to get the top deal – our links take you to the eligibility checker.

Drawbacks of balance transfer credit cards 

These cards don’t charge any interest on balances during the offer period, but some do charge a fee to transfer the debt.

The card providers that do charge fees generally offer a longer 0% period. On the other hand, providers that don’t have a transfer fee usually have a shorter interest-free period.

Any balance that’s left after the 0% balance transfer offer expires will be charged interest at the card provider's set rate. So, it’s important to pay any balance before the offer period expires.
