Key Takeaways
- • The FCA and HM Treasury are implementing the biggest overhaul of UK alternative investment fund manager (AIFM) regulations since 2013, with reforms outlined in HM Treasury's draft AIFM Regulations 2026 and two FCA consultation papers (CP26/28 and CP26/26).
- • AIFMs will be reclassified into small, medium, and large categories based on net asset value (NAV) of managed funds, with lighter-touch regulatory requirements for small AIFMs and more prescriptive rules for larger managers, replacing the previous full-scope versus below-threshold distinction.
- • The proposed reforms eliminate the small registered AIFM category, simplify investor disclosure and annual reporting for AIFMs managing assets below £500 million, and relax existing delegation requirements by shifting to a post-notification approach.
- • Regulatory burden is being reduced through removal of strict liability for external valuers, clarification of the AIF definition (including implicit "defined investment policy"), and transferring prescriptive rules to the FCA Handbook rather than legislation to enable faster regulatory updates.
- • Non-UK fund managers marketing in the UK and depositaries are subject to material changes, including new requirements for delegates to demonstrate adequate expertise, resources, and governance across all AIFM size categories.
Summary
The FCA and HM Treasury have launched a comprehensive consultation on reforms to the UK Alternative Investment Fund Manager (AIFM) regulatory framework, representing the most substantial changes to fund manager regulation since the original 2013 rules. The reforms are articulated across HM Treasury's draft AIFM Regulations 2026, two primary FCA consultation papers (CP26/28 on the UK AIFM Regime and CP26/26 on Fund Reporting for Asset Management Entities), and proposed new reporting templates. A separate consultation paper (CP26/27) addresses remuneration rules for solo regulated firms including AIFMs.
The regulatory restructuring introduces a three-tier classification system for AIFMs based on the net asset value of funds under management. This replaces the existing distinction between full-scope and below-threshold AIFMs, effectively abolishing the small registered AIFM category. The new framework applies differentiated regulatory intensity: small AIFMs operate under a lighter-touch regime, while medium and large managers face more prescriptive requirements broadly aligned with current rules for larger entities. This stratification allows regulators to calibrate requirements proportionally to systemic risk and market impact.
Significant relief measures are embedded throughout the proposals. Investor disclosure and annual reporting requirements are simplified for AIFMs managing assets below £500 million. Delegation rules are relaxed through adoption of a post-notification rather than pre-notification approach, reducing compliance friction for operational outsourcing arrangements. The FCA proposes removing strict liability for external valuers, lowering compliance costs for valuation functions. Regulatory clarifications include confirmation that "raising capital" encompasses historic, current, and future fundraising activities, and that a "defined investment policy" can be implicit rather than explicit.
The legislative approach has been redesigned for regulatory flexibility: most prescriptive rules will be codified in the FCA Handbook rather than legislation, enabling the regulator to update requirements expeditiously as market structures and fund strategies evolve. Additionally, the FCA proposes streamlining depositary requirements for small AIFMs by exempting them from mandatory depositary appointment while applying CASS 6 (client assets) rules instead, reducing operational overhead. All authorized UK AIFMs, irrespective of size, must ensure that delegates possess adequate expertise, resources, and governance structures—a universal baseline maintaining regulatory standards across the sector.
These reforms acknowledge the UK's status as a major hedge fund jurisdiction (hosting approximately 80% of Europe's hedge funds) while recognizing the need for proportionate regulation that reduces unnecessary compliance costs without compromising investor protection or systemic stability. Non-UK fund managers marketing into the UK should monitor final guidance, as the new framework will materially affect authorization, reporting, and operational requirements.
