Best Credit Cards UK: How to Compare and Choose0% Purchase Credit Cards: How They Work
How 0% purchase cards work, what you could save, the traps, what happens when the offer ends, and how they compare with other borrowing.
A 0% purchase credit card lets you spread the cost of purchases over months or years without paying any interest — as long as you clear the balance before the promotional period ends. The key difference from a balance transfer card: you are making new purchases interest-free, not moving existing debt.

0% Purchase Card vs 0% Balance Transfer — What’s the Difference?
| 0% Purchase card | 0% Balance transfer card |
|---|
| Purpose | New purchases, interest-free | Moving existing card debt |
| What the 0% applies to | Purchases made on the card | Balance transferred from another card |
| Transfer fee | N/A | Typically 2–3% of balance |
| Best for | Planned large purchases | Clearing existing card debt |
| Can you do both? | Some cards offer both — check terms | Some cards offer both |
How Much Could You Save?
Example: You need to buy a new laptop (£1,200) and a new washing machine (£600) — total £1,800.
| Option | Cost over 18 months |
|---|
| 0% purchase card, pay £100/month | £0 interest (balance cleared in 18 months) |
| Standard credit card at 25% APR, pay £100/month | ~£385 interest |
| Personal loan at 8%, 18 months | ~£120 interest |
The 0% purchase card saves ~£385 vs a standard credit card — as long as the balance is cleared before the 0% period ends.
Section 75 Protection — A Key Advantage
When you buy a single item costing over £100 and up to £30,000 on a credit card (including a 0% purchase card), Section 75 of the Consumer Credit Act makes the card provider jointly liable with the retailer if:
- The goods are not delivered
- The goods are faulty and the retailer refuses to refund
- The retailer goes bust before the order arrives
This protection does not apply to debit cards, buy-now-pay-later services, or cash. It is one of the strongest arguments for putting large purchases on a credit card.
Rules for Safe Use
- Set up a direct debit for at least the minimum payment — never miss a payment, or you lose the 0% deal
- Calculate the monthly payment needed to clear the full balance before the 0% period ends
- Set a calendar reminder for one month before the promotional period ends
- Do not use it for cash advances — cash withdrawals attract immediate interest at the card’s full rate
- Do not apply for multiple cards at once — each application leaves a hard search on your credit file
Eligibility — Who Gets the Best Deals?
0% purchase cards require a good-to-excellent credit score. Lenders look at:
- Credit history length (2+ years of on-time payments)
- Existing debt levels
- Income and employment stability
- Number of recent credit applications
Use a soft eligibility check (available on most comparison sites) to see your chances without affecting your credit score.
