Payday Loans and High-Cost Credit: What the FCA Rules Actually Protect You From

Payday loans and other high-cost short-term credit products have a well-earned reputation for being expensive, but a set of FCA rules - now in place for a number of years - significantly limit how much they can actually cost you compared with the pre-regulation era. Here’s exactly what protection exists.

The price cap that applies to payday loans

Since the FCA introduced its price cap on high-cost short-term credit, payday-style loans have been subject to three specific limits:

• Initial cost cap: interest and fees can’t exceed 0.8% per day of the amount borrowed.
• Default fee cap: if you miss a payment, fixed default charges can’t exceed £15, and interest on unpaid balances can’t exceed the initial 0.8% daily rate.
• Total cost cap: the total of all fees and interest over the life of the loan can never exceed 100% of the amount originally borrowed - meaning you can never be required to repay more than double what you borrowed, regardless of how long repayment takes or how many charges accrue.

Why the total cost cap is the most important protection

Before this cap was introduced, payday loan debts could spiral well beyond the original amount borrowed through repeated rollovers, extensions, and compounding fees, occasionally reaching multiples of the original loan. The 100% total cost cap makes this specific kind of runaway debt spiral structurally impossible for FCA-regulated payday loans - a genuinely significant consumer protection.

What counts as ‘high-cost short-term credit’ under these rules

The FCA’s definition specifically covers loans with an APR of 100% or more, intended to be repaid within 12 months or less. Many products marketed under different names (short-term loans, instant loans) fall within this definition and are subject to the same caps, even if they don’t use the term ‘payday loan’ explicitly.

Affordability checks are mandatory

Lenders offering high-cost short-term credit are required to carry out affordability assessments before lending, checking that repayment is realistically achievable without the borrower needing to borrow again or fall into financial difficulty as a result. This is separate from, but complementary to, the price caps themselves.

What the caps don’t do

• They don’t make payday loans cheap - even at the capped rate, a 0.8% daily rate compounds to a very high effective APR over a full year, so these remain among the most expensive mainstream credit products even with the cap in place, in the same territory as, or higher than, the already-expensive APRs typically charged on arranged overdrafts.
• They don’t prevent taking out multiple loans from different providers, which can still lead to an unmanageable total burden even if each individual loan is capped.
• They don’t apply to all forms of high-cost credit - some rent-to-own products, guarantor loans, and certain other credit types have different, though still regulated, rules.

Why BNPL was, until recently, outside this framework entirely

Buy Now, Pay Later products specifically avoided this kind of regulation because they were structured as interest-free, short-instalment credit that fell outside the traditional definition of regulated consumer credit - a gap that’s being closed from 15 July 2026 (see our dedicated BNPL regulation article) but which meant BNPL had none of these protections until that date.

If you’re considering high-cost credit

• Check whether the lender is FCA-authorised, using the FCA’s register, before borrowing from any short-term credit provider.
• Consider whether a credit union might offer a lower-cost alternative for a similar amount - credit unions are specifically designed to offer more affordable short-term borrowing to members, often at rates far below high-cost credit providers.
• If you’re already struggling with high-cost credit debt, free advice from StepChange, National Debtline, or Citizens Advice can help assess your options, including whether a formal debt solution (see our dedicated DMP vs IVA article) might be appropriate.

The bottom line

FCA price caps have meaningfully reduced the worst potential harms of payday-style lending, particularly by making runaway, ever-compounding debt structurally impossible under the 100% total cost cap. But these products remain expensive by design, and the caps don’t make them a low-cost borrowing option - they simply limit how bad the worst-case outcome can be.
