Search for best payday loan, and you’ll get a wall of lenders all claiming to be the cheapest, fastest, and friendliest. The truth is that in the UK, the price of a payday loan is capped by law, so the headline rate is rarely what separates a good deal from a bad one. What actually matters is authorization, total cost in pounds, the repayment terms, and whether there’s a cheaper option you’ve overlooked. This guide from Fast Loan UK sets out the ten checks worth making before you apply anywhere.
Here are the ten things to check before you borrow.
1. The lender is FCA authorized — and you’ve verified it yourself
Every firm lending or brokering high-cost short-term credit in the UK must be authorized by the Financial Conduct Authority. Don’t take a website’s word for it. Search the firm’s name or reference number on the FCA’s Financial Services Register and confirm the permissions match what they’re offering.
If a lender isn’t on the register, walk away. Unauthorized lending is illegal; you lose every consumer protection listed below, and you have no route to the Financial Ombudsman Service. Illegal money lending should be reported to the Stop Loan Sharks team in your nation.
2. The cost sits inside the FCA price cap
Since January 2015, there has been a legal ceiling on what high-cost short-term credit can cost, and it has three parts:
- 0.8% per day maximum in interest and fees on the amount borrowed
- £15 maximum fixed default fee if you miss a payment
- 100% total cost cap — you can never repay more in interest and charges than you originally borrowed
In practice that means borrowing £100 for 30 days and repaying on time should cost no more than £24 in interest and fees. Anything above the cap is a breach of FCA rules, not a “premium product”.
Worth knowing for 2026: the FCA has been reviewing whether the cap is still fit for purpose. It has completed its stakeholder roundtables and has said it currently sees no evidence for change, so the caps above remain the benchmark.
3. The total repayment is shown in pounds, not just APR
APR is a legally required disclosure, but on a 30-day loan it produces figures in the hundreds or thousands of percent and tells you almost nothing useful. APR annualizes a cost that was never meant to run for a year.
The number that matters is the total amount payable — the cash sum leaving your account, and the date it leaves. A good lender puts that in front of you before you commit, not buried in a PDF after approval. Under the FCA’s Consumer Duty, communicating total cost clearly and up front isn’t a courtesy; it’s an obligation.
4. The term matches your actual pay cycle
The single most common reason a short-term loan turns into a long-term problem is a repayment date that lands before you’re paid, or one that swallows so much of your wage that you’re short again the following week.
Before you apply, work out what’s left after rent, council tax, energy, food and travel. If the repayment doesn’t fit inside that gap comfortably, the loan isn’t affordable — regardless of what the eligibility checker says.
5. The affordability check is a real one
A lender that approves you in seconds without looking at income and expenditure isn’t doing you a favor. FCA rules require a creditworthiness and affordability assessment before lending, and the regulator has moved firmly into enforcement mode on Consumer Duty outcomes.
Many lenders now use Open Banking to read your actual transaction history rather than relying on a thin credit file. That’s usually a good sign — it tends to produce more accurate decisions for people with limited credit history.
6. There’s no penalty for repaying early
Under the Consumer Credit Act you have a 14-day right of withdrawal from the day after the agreement is made. Exercise it and you repay the capital plus interest for the days you actually held the money — nothing more.
You also have a statutory right to settle early at any point and receive a rebate of interest. A well-run lender makes both of these easy to do online. If early repayment carries a fee or you can’t find how to do it, treat that as a red flag.
7. You understand how the repayment is collected
Most short-term loans are collected by Continuous Payment Authority (CPA) — a recurring authority on your debit card, not a Direct Debit. FCA rules limit lenders to two unsuccessful attempts to collect under a CPA, and they cannot take part-payments.
You can cancel a CPA at any time by telling your bank, and your bank must stop it. Canceling the payment does not cancel the debt, but it does stop repeated attempts draining an account you need for essentials. Know which method your lender uses before you sign.
8. Rollovers aren’t part of the sales pitch
Lenders may extend a loan a maximum of two times. But a rollover means paying more interest on money you’ve already struggled to repay, and needing one is a signal that the original loan wasn’t affordable.
A lender genuinely acting in your interests should respond to a missed payment by offering forbearance — a payment plan, a freeze on interest and charges, or a referral to free debt advice — not by selling you an extension.
9. There’s a clear complaints route
Check the complaints procedure before you need it. An FCA-authorised firm must have one, must respond within eight weeks, and you can then take the complaint to the Financial Ombudsman Service free of charge. That protection exists only with authorized firms — another reason step one matters.
10. You’ve genuinely compared it against the cheaper alternatives
The best payday loan is often no payday loan. Before you borrow at 0.8% a day, rule these out:
- Credit unions — interest is capped by law at 3% a month on the reducing balance in England, Wales and Scotland (a maximum of 42.6% APR), and 1% a month in Northern Ireland. Many charge less, and there are usually no arrangement or early repayment fees. You need to meet the common bond to join.
- Universal Credit Budgeting Advance — an interest-free DWP loan from £100 up to £348 (single), £464 (couple) or £812 (with children), repaid from future payments, typically over 24 months. You’ll usually need six months on UC. On legacy benefits, the equivalent is an interest-free Budgeting Loan.
- The Crisis and Resilience Fund — replaced the Household Support Fund in England on 1 April 2026 and runs to March 2029. It’s administered by your local council and can include grants you don’t repay. Scotland, Wales and Northern Ireland have their own schemes.
- Talking to the creditor first — energy suppliers, water companies and councils all run hardship schemes and payment plans. A repayment arrangement usually beats new borrowing.
- An arranged overdraft or an existing credit card — not cheap, but often cheaper over a short period.
- Employer salary advance schemes, if your workplace offers one.
The bottom line
There is no single “best payday loan” — the cap means most authorized lenders cluster around a similar price. What varies is transparency, flexibility, how affordability is assessed, and how you’re treated if something goes wrong. Judge lenders on those four things.
And if you’re borrowing to cover borrowing, or you’ve taken more than one short-term loan in the past few months, that’s the point to stop and get free, confidential debt advice. StepChange, National Debtline, Citizens Advice and MoneyHelper all provide it at no cost.
