United Kingdom AML/CFT: A Reference Guide

An overview of the United Kingdom's anti-money-laundering and counter-terrorist-financing framework, the bodies that run it, its statutory history, and the core obligations on regulated firms.

Last updated 2026-06-20

The United Kingdom operates a multi-body anti-money-laundering and counter-terrorist-financing (AML/CFT) regime. Policy sits with HM Treasury; supervision is divided across a conduct regulator, statutory bodies, and professional-body supervisors; financial-intelligence and consent functions sit with the National Crime Agency; financial sanctions are implemented by OFSI; and corporate-transparency data is held by Companies House. This guide summarises the principal bodies, the legislative timeline, the current framework, and the core obligations on regulated firms, with citations to primary authorities.

Current framework and core obligations

Customer due diligence (CDD) and enhanced due diligence (EDD). MLR 2017 (as amended) requires regulated firms to identify and verify customers and beneficial owners, understand the purpose and nature of the relationship, and apply EDD to higher-risk situations — including politically exposed persons (PEPs), high-risk third countries, and complex or unusual transactions. CDD must be risk-based and ongoing. legislation.gov.uk/uksi/2017/692

Risk-based approach. Firms must maintain a documented business-wide risk assessment, policies, controls and procedures and, where size warrants, a nominated officer (MLRO) and independent audit (MLR 2017, Parts 2–3).

SARs and the DAML consent regime. Under POCA, the principal money-laundering offences are ss.327–329. A person can obtain a defence by making an authorised disclosure (a SAR) to the NCA and obtaining appropriate consent (ss.335, 338) — known as a Defence Against Money Laundering (DAML). Statutory timing comprises a 7-working-day notice period and, if consent is refused, a 31-calendar-day moratorium; absent a refusal within the notice period, consent is deemed. An equivalent terrorist-property defence (DATF) applies under TACT. legislation.gov.uk/ukpga/2002/29/part/7; NCA UKFIU DAML/DATF guidance

Beneficial ownership and the PSC register. UK companies must identify and file People with Significant Control (over 25% of shares or voting rights, or significant influence or control) at Companies House — a public register. Overseas entities owning UK land must disclose registrable beneficial owners via the Register of Overseas Entities (ECTEA 2022). gov.uk/guidance/people-with-significant-control-psc

Financial sanctions. Since 31 December 2020 the UK has operated its own sanctions regime under SAMLA 2018, independent of the EU: the FCDO designates and OFSI implements financial sanctions. Breaching UK financial sanctions is a strict-liability matter — OFSI can impose civil monetary penalties without proving knowledge — and firms in scope have mandatory reporting duties to OFSI when they identify designated persons or frozen assets. legislation.gov.uk/ukpga/2018/13; OFSI

Penalties. POCA money-laundering offences carry up to 14 years' imprisonment. MLR 2017 breaches expose firms to FCA and HMRC civil penalties and, in serious cases, criminal liability (POCA ss.327–334). legislation.gov.uk/ukpga/2002/29

Recent developments

DateDevelopmentNotes
1 Sep 2025ECCTA "failure to prevent fraud" offence comes into force.A corporate offence for large organisations (turnover over £36m, balance sheet over £18m, or more than 250 employees) where an associated person commits fraud for the organisation's benefit; a defence is available where reasonable prevention procedures were in place.
8 Apr 2025Companies House identity verification (IDV) regime launches on a voluntary basis.Part of ECCTA implementation, including the authorised corporate service provider (ACSP) framework.
18 Nov 2025IDV becomes mandatory for new director appointments and new PSC registrations.Reported to be phased for in-post directors and existing PSCs over the months that follow.

According to HM Treasury, the UK is moving toward a single professional-services AML supervisor for the legal and accountancy sectors, with the FCA identified as the intended body; HMT consulted on the proposal in late 2025. The FCDO and HMT have also announced plans to consolidate UK sanctions designations into a single UK Sanctions List, after which the separate OFSI Consolidated List would cease to be updated; firms should confirm timing and scope against the FCDO and OFSI primary notices.
