In October 2025, the UK government confirmed a major overhaul of the anti‑money laundering (AML) and counter‑terrorist financing (CTF) supervisory landscape. The Financial Conduct Authority (FCA) will assume responsibility as the Single Professional Services Supervisor (SPSS), taking over from the Solicitors Regulation Authority (SRA) and more than 20 other professional body supervisors.
This reform marks one of the most significant regulatory shifts in the legal sector in over a decade, aiming to simplify a fragmented system and strengthen the UK’s resilience to financial crime.
Designed to create a more consistent and robust regime
Although the transition will take several years and requires enabling legislation, legal sector firms should expect a more assertive, data‑driven, and interventionist style of supervision under the FCA. The Treasury has made clear that the reform is intended to eliminate longstanding inconsistencies in AML supervision, improve transparency, and ensure stronger enforcement across professional services.
The FCA’s model emphasises granular evidence, data analytics, and higher expectations around demonstrable compliance, even though the underlying AML rules themselves, the Money Laundering Regulations 2017 (MLRs), remain unchanged.
Key details of the upcoming transition
- Higher fines and stronger enforcement: the SRA previously had a £25,000 cap on internal fines, with serious breaches escalated to the Solicitors Disciplinary Tribunal. Under the FCA, firms will be subject to a regime known for issuing significantly higher penalties, including multi‑million‑pound fines in the financial sector. The FCA has publicly stated that the reform will enhance its ability to identify and disrupt financial crime.
- A “culture shock” for firms: Legal sector specialists anticipate a a cultural shift as firms accustomed to the SRA’s guidance‑led approach adapt to the FCA’s more intensive supervisory methods. The FCA’s risk‑based methodology relies heavily on proactive data provision, documented decision‑making, and rigorous evidence of control effectiveness.
- Timeline and legislative process: while the government confirmed the move in October 2025, the transition will come into effect only after new legislation is passed and a detailed delivery plan is agreed. HM Treasury ran a consultation to define the FCA’s powers, closing in December 2025, and further announcements are expected in 2026 as the transition plan is finalised. Full implementation may take several years, with some industry sources modelling timelines stretching toward 2029.
- Impact on existing AML procedures: despite the supervisory change, firms’ core obligations under the Money Laundering Regulations 2017 remain completely unchanged. The government and FCA have repeatedly emphasised that “firms that are already compliant should not need to make changes to their AML/CTF controls.”
- Concerns about “double jeopardy” and regulatory overlap: professional bodies, including the Law Society, have raised concerns that FCA oversight could create regulatory overlap, with the FCA investigating AML failures while the SRA continues to investigate professional misconduct. This raises the risk of “double jeopardy” and disproportionate burdens on legal practices. The Law Society has also voiced concerns around proportionality, sector‑specific expertise, and the protection of legal professional privilege.
Background to the change
The reform stems from a 2023 HM Treasury consultation prompted by criticism from the Financial Action Task Force (FATF) regarding weaknesses in the UK’s fragmented AML supervisory framework. FATF previously flagged inconsistent standards, uneven enforcement, and insufficient data sharing between supervisors.
The SRA has strengthened its AML approach in recent years – including issuing a £500,000 fine to a major law firm – but under the new model, AML supervision for the legal sector will now sit solely with the FCA. This consolidation aligns the legal profession with other sectors already under public‑sector AML oversight, such as financial institutions and gambling operators.
What this means for law firms
Although the regulatory shift is structural rather than procedural – for now – firms should view the transition as a wake‑up call to enhance documentation, evidence gathering, risk assessments, and governance. The FCA’s expectations for data quality, decision‑making trails, and audit readiness are significantly higher than those currently experienced under the SRA. Firms that prepare early will be best positioned to avoid disruption during the transition window.
