UK credit card borrowing costs hit multi‑decade highs in early 2025 before showing small signs of easing after the Bank of England cut the Bank Rate in August 2025. That shift affects everyday spending, travel, and how much it costs to smooth bills—especially if you’re rebuilding credit. Moneyfacts reported record purchase APRs, and banks began to pass on a modest part of the August 2025 rate cut at different speeds.
This guide breaks down the latest credit card interest rate statistics 2025, why rates are where they are, and practical ways to reduce what you pay—whether you clear in full each month or carry a balance for a while. For context, Moneyfacts flagged the market’s record‑high purchase APRs in 2025 (news summary; media centre).
Credit card interest rate statistics 2025: UK APR trends at a glance
Here are the headline UK numbers most readers look for. They summarise how borrowing costs have moved across 2025.

Quick definitions
- APR: The annual percentage rate. It wraps the interest rate plus most compulsory fees into a single yearly cost figure.
- Purchase rate: The interest rate that applies to everyday card spending when you don’t clear your statement balance in full.
- Cash rate: The (usually higher) interest rate on cash withdrawals and cash‑like transactions; interest starts immediately.

Why different sources disagree: APR vs ‘effective interest rate’
Two reputable numbers often appear in UK coverage: Moneyfacts’ average representative APR and the Bank of England’s “effective interest rate.” They answer different questions, so they rarely match.
- Moneyfacts average representative APR
• What it includes: Advertised representative APRs for cards on the market. These wrap the purchase rate plus standard fees into one figure.
• How it’s calculated: Market‑wide analysis of representative APRs publicly quoted by issuers.
• How to use it: A snapshot of what’s being offered to at least 51% of accepted applicants, not what you personally will get. - Bank of England “effective interest rate”
• What it includes: The actual interest paid on interest‑charging card balances across the system. It excludes annual fees and people on 0% deals.
• How it’s calculated: From banks’ data submissions in the BoE’s Money & Credit: Effective interest rates release.
• How to use it: A barometer of what cardholders are paying on revolving balances.
“Representative APR” means that at least 51% of people accepted for the product must be offered that APR. Individual APRs vary by credit profile.
FCA Handbook CONC 3.5
If you’re near‑prime or building credit, your personal APR can be higher than the headline representative figure. Lenders price for risk, so checking your eligibility first (via a soft search) can help you avoid unnecessary score hits while you compare real, personalised rates.
What moved UK card APRs in 2025
- Base rate cut, limited pass‑through. The Bank Rate moved down in August 2025 (from 4.25% to 4.00% on 7 August, per Santander’s update), but card APRs didn’t fall one‑for‑one because issuers set wider margins and adjust more slowly.
- Issuer pricing and caps/spreads. Some providers link card rates to the Base Rate but cap or floor them, so changes can be uneven. See Bank of Scotland’s base‑rate information for how tracking works in practice.
- Competitive dynamics at record levels. Despite the base‑rate cut, market purchase APRs hit new highs in 2025 as lenders competed on rewards/0% terms rather than headline rates (Financial Times; Moneyfacts).
- Risk‑based pricing. For higher‑risk segments, APRs stayed elevated to reflect expected losses and capital costs. The BoE’s effective card rate eased only slightly in July/August 2025, underscoring a slow reset (BoE Money & Credit).
Near‑prime reality: costs, access and the 51% rule
Representative APR is a guide, not a promise. UK rules say at least 51% of people accepted for a card must be offered the advertised representative APR—others can be offered higher rates based on credit checks and affordability. That’s codified in FCA CONC 3.5.
In today’s market, the average advertised card APR sat around 36% in August 2025 (Finder UK). Many credit‑builder cards price in the high‑30s to 40s because they’re designed for people with thinner files or past blips. If you’re rebuilding, use soft‑search eligibility checks first. They show your likely APR and limit without leaving a hard footprint on your credit file.
How much does APR change cost you? Three quick UK examples
Assume you carry an average daily balance of £1,000 for a full year and make no repayments. Using a daily rate method (APR ÷ 365) with daily compounding:
Purchase APR | Approx. interest over 12 months |
---|---|
22% | ~£246 |
36% | ~£434 |
49% | ~£636 |
Takeaways: paying your statement balance in full each month avoids purchase interest entirely. If you do carry a balance, even a small APR reduction matters over time. Figures are illustrative and don’t reflect fees, partial repayments, or rate changes.
How to pay less interest in 2025 (without harming your credit)
- Clear in full to unlock the grace period. Many cards give up to 55–56 days interest‑free on purchases when you pay your statement balance in full and on time (Barclaycard explainer; HSBC guide).
- Automate good habits. Set up a Direct Debit for at least the statement balance (or more) and add calendar reminders a few days before the due date.
- Avoid cash advances. They have no interest‑free period, usually a higher rate, and often a cash fee on top. Use a debit card or cash instead where possible.
- Consider 0% offers if you qualify. Balance‑transfer and purchase 0% windows lengthened in 2025, but check transfer fees and revert rates before applying (Moneyfacts; Moneyfacts Compare).
- Use soft‑search eligibility checkers first. They show your likelihood of approval and an estimated APR without affecting your credit score (MoneyHelper).
- Compare with a fixed‑rate personal loan. If you’re consolidating, weigh the total cost (APR, any fees, repayment term) of a fixed‑rate loan against your current card APR.
Struggling with persistent debt? If you’ve paid more in interest/fees than towards reducing your balance over 18–36 months, contact your lender early—there are FCA‑backed steps to help you repay faster and pay less in interest (FCA guidance).
Spending abroad in 2025: FX fees, cash advances and safer choices
Many UK cards add a foreign transaction fee of around 2.75%–2.99% on non‑sterling purchases. Cash withdrawals abroad usually add a cash‑advance fee and start charging interest straight away (Barclaycard fees; Virgin Money FX; market overview via Forbes Advisor UK).
- Pay in the local currency to avoid costly dynamic currency conversion (DCC).
- Avoid using a credit card for ATM cash unless it’s an emergency—there’s no grace period and fees apply.
- If you travel, consider a card with £0 FX fees.
For example, the 118 118 Money Credit Card has no foreign transaction fees and offers up to 51 days’ interest‑free on purchases when you pay in full; cash advances carry a fee (see product page and FAQs for details, terms apply).
Outlook: where UK credit card APRs could head next
With the Bank Rate starting to fall, card APRs may drift down only gradually. Issuer margins, funding costs, and risk appetite matter just as much. The Bank of England’s effective card rate edged lower in August 2025, while inflation stayed above target, which can keep pricing elevated even as base rates ease (BoE Money & Credit, Aug 2025; ONS CPI, Aug 2025).
Focus on what you can control: clear in full if you can, automate payments, avoid cash advances, and always use eligibility checkers to see your personal rate before you apply.
