This Practice Note examines some of the key aspects of regulation applicable to high-cost short-term credit (HCSTC) including its definitions, the regulatory framework, the Financial Conduct Authority’s (FCA) high-cost credit review and conduct requirements specific to providers of HCSTC (including limits on roll-overs, continuous payment authorities (CPAs), the use of price comparison websites (PCWs) and cost caps). From 15 July 2026 (Regulation Day), a significant part of the previously unregulated ‘Buy now, pay later’ (BNPL) market, specifically interest-free, short-term, third-party lender arrangements, will be brought within FCA regulation as deferred payment credit (DPC). This Practice Note focuses on the HCSTC regime. For more information about BNPL and the DPC regime (including the new perimeter and conduct requirements), see Practice Note: Buy now, pay later (BNPL) and deferred payment credit (DPC). What is 'high-cost short-term credit' High-cost credit, often referred to generically as payday lending, can include payday loans, home-collected credit, catalogue credit, rent-to-own (RTO), pawn-broking, guarantor and logbook loans. HCSTC is a specific category of regulated credit within this wider high-cost credit market.
