Best Low-Interest Credit Cards in the UK (2024)

UK credit card "low interest" usually means 0% purchase introductory offers (12–28 months) followed by a revert APR. True low ongoing APR cards are rare. Below are competitive options as of mid-2024 (rates variable, subject to status).

Top 0% Purchase Cards (Longest Interest-Free Windows)

Low Ongoing APR Cards (No/Short 0%)

• Post Office Money Credit Card: 0% purchases 6 mo, then 22.9% APR. Low fee BT.
• MBNA Low Rate: 7.9% APR (fixed) on purchases/balance transfers. £24/yr fee. Rare fixed rate.

Critical Checks Before Applying

• Eligibility Checker (Soft Search): Use MoneySavingExpert, ClearScore, Experian, TotallyMoney — no credit file footprint.
• Representative APR: Only 51% of accepted applicants get the advertised rate. You may get higher.
• Balance Transfer (BT) vs Purchase: Tables above are for purchases. BT offers differ (0% 28–34 mo + 2–3.5% fee).
• Minimum Repayment: 1% + interest or £25. Paying only minimum = decades of debt.
• Section 75 Protection: £100–£30k purchases covered (joint liability with retailer).

Strategy

If you carry a balance, prioritize lowest revert APR (Virgin, Nationwide, MBNA, TSB) over longest 0%. If you pay in full monthly, get a rewards/cashback card (Amex Platinum, Chase, John Lewis) — interest irrelevant.
