A comprehensive comparison across scope, rules, reporting, and supervisory expectations.
1. Regulatory Basis & Direction of Travel
| Topic | UK AIFM Regime | EU AIFMD / AIFMD II |
| Regulatory direction | Diverging from EU model; creating a lighter, more flexible UK-specific regime. | Increasing regulation under AIFMD II with expanded requirements. |
| Source of rules | Moving rules from legislation into FCA Handbook, enabling faster amendments. | Rules remain part of the EU legislative framework, including Level 1 & 2 measures. |
| Objective | Reduce burdens, enhance proportionality, promote competitiveness (“Brexit dividend”). | Strengthen investor protection, enhance supervision, harmonise EU practices. |
2. AIFM Classification & Thresholds
| Topic | UK AIFM Regime | EU AIFMD / AIFMD II |
| AIFM thresholds | Removed entirely (no €500m/€100m cliff-edges) | Thresholds remain integral to classification of small vs full-scope AIFMs. |
| Basis of categorisation | Based on activities and risk, not AUM | Based primarily on AUM thresholds and leverage. |
| Outcome | No abrupt compliance jumps; more proportionate regulation | Possible cliff-edge effects when crossing AUM thresholds. |
3. Authorisation Perimeter
| Topic | UK AIFM Regime | EU AIFMD / AIFMD II |
| Authorisation scope changes | Perimeter is being redrawn; more managers (e.g., unauthorised property CIS, internal AIFMs) will require FCA authorisation | No equivalent perimeter overhaul; scope largely unchanged. |
| Regulatory emphasis | Activity‑based oversight. | Entity/AUM‑based oversight. |
4. Reporting & Transparency
| Topic | UK AIFM Regime | EU AIFMD / AIFMD II |
| Reporting framework | FCA expected to restate/replace Annex IV‑style reporting in new UK formats. | Annex IV reporting maintained and expanded under AIFMD II. |
| Disclosure updates | Rulebook‑based approach; easier to adjust over time. | More extensive investor disclosures under AIFMD II (e.g., fees, delegation, liquidity tools). |
| Cross‑border marketing via NPPR | NPPR preserved and restated, maintaining openness to global AIFs. | NPPRs continue to exist but subject to stricter AIFMD II requirements, some countries are tightening. |
5. Management Activities & Operational Requirements
| Topic | UK AIFM Regime | EU AIFMD / AIFMD II |
| Loan origination rules | UK is not adopting AIFMD II loan-originating fund rules. | AIFMD II introduces detailed rules on lending, leverage caps, borrower exposures. |
| Liquidity management | UK intends flexibility; details to be set by FCA. | Harmonised liquidity tools and mandatory access requirements under AIFMD II. |
| Depositary requirements | No major reforms announced. | Broader depositary reforms: cross‑border depositary services, additional duties. |
| Delegation oversight | FCA to set expectations through Handbook, likely activity‑focused. | AIFMD II introduces enhanced delegation oversight and ESMA notification. |
6. Transition Timelines
| Topic | UK AIFM Regime (2025–2026) | EU AIFMD II (by 2026) |
| Consultations | HMT + FCA launched April 2025; feedback June 2025. | AIFMD II final text published; implementation in progress. |
| Rule Finalisation | FCA detailed rule consultation in 2026; final rules expected late 2026. | AIFMD II effective April 2026 across EU. |
| Implementation period | Expected phased/transition approach. | EU Member States must transpose by 2026. |
7. Strategic Impact for Firms
| Area | Impact in UK | Impact in EU |
| Compliance burden | Lower, more flexible regime. | Higher under AIFMD II. |
| Regulatory divergence | Material divergence from AIFMD II. | Increasing harmonisation across EU. |
| Cross-border access | NPPR remains open and predictable. | EU encourages passporting; NPPR subject to local tightening. |
| Competitiveness | UK positions itself as pro-innovation, proportionate. | EU focuses on investor protection and supervisory strength. |
Summary
The UK AIFM reforms represent one of the most significant post Brexit regulatory divergences, with the UK embracing proportionality, flexibility, and FCA-driven rulemaking, while the EU pushes ahead with AIFMD II’s increased oversight and detailed operational requirements.
