FCA Payday Loan Price Cap — What You Need to Know

Since January 2015, the Financial Conduct Authority has imposed strict limits on payday loan costs. These rules protect borrowers from spiralling debt and apply to all FCA-authorised high-cost short-term credit lenders.

FCA RuleLimitExample (£300 loan)
Daily interest and fee cap0.8% per day maximumMax £2.40/day = £67.20 for 28 days
Total cost cap100% of original loanMax charges of £300 on a £300 loan
Default fee cap£15 maximumCannot charge more than £15 if you miss a payment
Rollover limit2 rollovers maximumCannot keep extending beyond 2 extensions
Warning: APR figures for payday loans appear extremely large (often 300%–1,500%) because they annualise a short-term cost. A £24 charge on a £100 loan for 28 days is 0.857% per day — the equivalent annual rate is ~1,281% APR. This does not mean you will pay 1,281% if you repay in 28 days, but if you rolled the loan over for a year, you effectively would.

Frequently Asked Questions

What is the FCA cap on payday loans?

Since January 2015, the FCA has capped payday loan costs at: 0.8% per day maximum interest and fees; a total cost cap of 100% (you can never owe more than double what you borrowed); and a default fee cap of £15. These rules apply to all FCA-regulated high-cost short-term credit lenders.

What is a typical payday loan APR?

Payday loan APRs are typically 300–1,500% representative APR. A common 28-day £100 loan costing £24 in interest has an APR of approximately 1,281%. The APR figure looks alarming because it reflects what you would pay if the loan ran for a full year — payday loans are designed for days, not years. However, rollover fees can trap borrowers into spiralling debt.

Are payday loans legal in the UK?

Yes, payday loans are legal in the UK but strictly regulated by the FCA. All payday lenders must be FCA authorised, follow responsible lending rules, and adhere to the price cap. Unlicensed lenders (loan sharks) are illegal and dangerous — only borrow from FCA-regulated lenders, which you can verify at register.fca.org.uk.

What are cheaper alternatives to payday loans?

Cheaper alternatives include: credit union loans (typically 3% per month = ~42% APR), an authorised overdraft (39.9% EAR — still far cheaper than 1,281% APR), a 0% money transfer credit card, a budgeting loan from the government (0% interest for benefits claimants), borrowing from family or friends, or a salary advance scheme through your employer.

What happens if I can't repay a payday loan?

If you cannot repay a payday loan, the lender must offer you a repayment plan. Under FCA rules, lenders cannot charge excessive default fees (capped at £15) and cannot roll over your loan more than twice. Contact the lender immediately and ask for a repayment arrangement. Free debt advice is available from StepChange, National Debtline, or Citizens Advice.

How is payday loan APR calculated?

Payday loan APR uses compound interest: APR = ((1 + daily_rate)^365 − 1) × 100, where daily_rate = total_interest / loan_amount / days. For example, a £100 loan for 14 days with a £10 charge: daily rate = 10/100/14 = 0.714% per day. APR = ((1.00714)^365 − 1) × 100 = 1,258% APR.

Can I get a payday loan with bad credit?

Many payday lenders offer loans to people with bad credit, using affordability assessments rather than just credit scores. However, FCA rules require lenders to check you can afford the repayments. Taking out a payday loan when you're already in financial difficulty is risky — consider free debt advice first.

What is the maximum payday loan amount in the UK?

There is no statutory maximum payday loan amount in UK law, but most lenders cap loans at £1,000–£1,500 for new customers, rising to £2,000 for returning customers with a good repayment history. The FCA's affordability rules mean lenders must ensure borrowers can repay without significant hardship.

How many times can a payday loan be rolled over?

FCA rules cap payday loan rollovers at two. A rollover means extending the loan for another term and paying additional interest. After two rollovers, you must either repay the loan or be given a repayment plan. Many lenders now refuse to offer rollovers at all.

Will a payday loan affect my mortgage application?

Yes, having a payday loan on your credit file can significantly harm a mortgage application. Many high street lenders automatically decline applications from borrowers who have had payday loans in the last 12–24 months. If you're planning to apply for a mortgage, avoid payday loans entirely and seek alternative short-term borrowing.

Is a payday loan the same as a logbook loan?

No — a payday loan is unsecured short-term credit, while a logbook loan is secured against your vehicle. With a logbook loan, the lender can repossess your car if you don't repay. Both are high-cost credit types regulated by the FCA, but logbook loans are even riskier because you could lose your vehicle.

What is the total cost cap on payday loans?

The FCA total cost cap means that all interest, fees, and charges on a payday loan cannot exceed 100% of the original loan amount. So if you borrow £200, you can never be asked to repay more than £400 in total (£200 original + maximum £200 in charges). This cap applies even if the loan is rolled over or you default.
