Christmas is a very expensive time of year, with many of us looking to save cash where we can.

Many of us will be using credit cards to help pay for all the food and presents and now Money Saving Expert Martin Lewis has revealed how you can cut your credit card debt.

Martin says if you've got outstanding credit card debt cutting the interest means your repayments clear the actual debt, so you can be debt-free faster.

The key thing you can do to achieve this is a 0% balance transfer, where you get a new card to pay off existing cards, so you now owe it, but interest-free.

Martin advises one card in particular that is best for this - The Santander 27mths 0% no fee - and it's not an 'up to'.

Those receiving the basic state pension will get a weekly boost in 2019/2020.

Martin says: "Most 0% balance-transfer cards charge a one-off fee, as a % of the debt shifted. However, Santander is 27mths 0% with no fee. So shift debt there correctly and it's totally cost-free.

"A few longer-0% cards are available. My mantra has long been 'get the card with the lowest fee in the time you're sure you can repay'. Yet while back in mid-2017 the longest 'fee' cards gave you 14mths more at 0% than the fee-free cards, now those longer 0% lengths have radically shortened.

"The Post Office is today's longest, but only gives 5mths more than the fee-free Santander card, so you don't get much extra for the 2% (£20 per £1,000) fee.

"Plus, unlike Santander, the Post Office is 'up to' 32mths 0%, so some get a shorter 0% period."
