A 0% purchase credit card is the most cost-effective way to finance a large planned purchase. Rather than taking out a personal loan or paying cash, you make the purchase on the card and repay it in monthly instalments during the promotional 0% period. As long as you clear the balance before the promotional period ends, you pay absolutely nothing in interest.

These cards are ideal for home improvements, furniture, holidays, or any significant purchase you know you can repay within one to two years. The key is to divide the total amount by the number of months in the promotional period and set up a direct debit for that exact amount each month.
