0% Purchase Credit Cards: A Complete UK Guide
0% purchase cards explained: interest-free periods, how they differ from balance transfers, and when they beat BNPL.

TL;DR: A 0% purchase card charges no interest on new spending for a set period, typically 20 to 26 months. It is the cheapest way to spread the cost of a large purchase if you clear the balance before the 0% ends. Unlike balance transfer cards there is no transfer fee, but the 0% usually covers purchases only, not transferred debt.
How 0% purchase cards work
Buy as normal on the card and pay no interest during the introductory period. In late September 2026, the longest purchase 0% periods reached 26 months. Divide the purchase by the number of months and set up a direct debit for that amount: that is the disciplined way to use one.
Purchase card vs balance transfer card
They solve different problems. A purchase card is for new spending; a balance transfer card is for existing debt. Dual “all-rounder” cards exist that offer 0% on both, but the specialist cards usually beat them on each side. If you need both, two specialist cards generally win, though that means two applications.
0% card vs buy now, pay later
BNPL became regulated credit on 15 July 2026, with affordability checks and Ombudsman access, which narrowed the gap. Practical differences remain: a 0% card gives up to around 26 months interest free versus weeks or months for BNPL, and card purchases between £100 and £30,000 carry Section 75 protection. BNPL splits one purchase into a few instalments; a card is reusable revolving credit.
Frequently asked questions
What happens when the 0% purchase period ends?
Any remaining balance starts accruing interest at the card’s standard APR, often around 24.9%. Plan the payoff from day one.
Can I get a 0% purchase card with average credit?
The longest 0% deals go to applicants with strong credit histories. Lenders publish no exact cut-offs, so use an eligibility checker (a soft search that will not affect your score) before applying. Not sure where you stand? Check your credit score free first, it takes a few minutes and never harms your score.
Should I use a 0% card for everyday spending?
Only if you clear it in full each month. Otherwise everyday spending at 0% quietly becomes debt you pay interest on later. Balance transfer guide.
