UK Financial Regulators: Agency Profiles

The UK regulatory framework separates conduct supervision from prudential supervision. The Financial Conduct Authority (FCA) is the primary conduct regulator for most financial firms and markets. The Prudential Regulation Authority (PRA), which operates within the Bank of England, oversees banks and insurers for financial soundness.

The Prudential Regulation Authority (PRA) will be profiled in a future update. The PRA, which sits within the Bank of England, supervises around 1,500 banks, building societies, credit unions, insurers, and major investment firms for financial soundness. Many larger UK firms are dual-regulated: they are FCA-authorised for conduct purposes and PRA-supervised for prudential purposes.

How UK financial regulation is structured

The twin peaks model introduced by the Financial Services Act 2012 divides regulatory responsibility between two authorities. The FCA is responsible for conduct of business rules: how firms treat customers, market integrity, and the prevention of financial crime. The PRA is responsible for prudential standards: whether banks and insurers hold enough capital and manage risk appropriately to remain solvent.

For most retail investors, the FCA is the relevant regulator. It authorises firms, maintains the Financial Services Register, handles complaints escalated from the Financial Ombudsman Service, and administers the Financial Services Compensation Scheme (FSCS) in coordination with other bodies. The FSCS provides protection for eligible claims up to defined limits when an FCA-authorised firm fails.

The Bank of England, through the Financial Policy Committee (FPC) and the PRA, is responsible for macroprudential oversight: monitoring systemic risks that could affect the stability of the broader financial system, not just individual firms.

Post-Brexit, the FCA and PRA have taken on a larger role in setting UK-specific rules that previously derived from EU legislation. This includes the Smarter Regulatory Framework (SRF) programme, which is progressively replacing retained EU law with UK-tailored rules.

Verifying a firm in the UK

The Financial Services Register, maintained by the FCA, is the primary tool for verifying whether a firm or individual is authorised to provide financial services in the UK. An authorised status means the firm has met FCA requirements and is subject to ongoing supervision. Firms offering regulated financial products without authorisation are operating illegally, and claims against them may not be covered by the FSCS.

The FCA also publishes a Warning List of firms known to be operating without authorisation or suspected of running scams. Checking both the Register and the Warning List before engaging with an unfamiliar firm is a standard due-diligence step for UK investors.
