UK AIFM Reforms: 20 Key Takeaways

29TH JULY 2026

 By Mike Booth, Managing Partner, Suntera UK

The FCA's proposed reforms to the UK AIFM regime represent one of the most significant changes to the alternative investment fund management framework since its introduction. While implementation is not expected before 2028, firms should begin assessing the impact of the new regime now. The proposals affect firms from existing sub-threshold managers to large full-scope AIFMs, with implications for governance, reporting, investor disclosures, remuneration and operational oversight.
 

1. Every AIFM Should Assess the Impact

The reforms affect all categories of AIFM. While the extent of change will vary depending on a firm's size and fund structure, every manager should assess how the new framework applies to its business and identify any actions required.

2. Firms Have Time to Prepare

The reforms are not expected to come into force until 2028, providing firms with a valuable opportunity to undertake impact assessments, develop implementation plans and make any necessary operational or governance changes.

3. New AIF Definition

The proposed definition of an Alternative Investment Fund has been broadened and may capture certain schemes currently classified as Collective Investment Schemes (CIS) that are not presently treated as AIFs. Firms should assess existing structures carefully and seek legal advice where classification is unclear.

4. Threshold Calculations

The current Gross Asset Value methodology will be replaced by a Net Asset Value (NAV) approach. In addition, AIFs and CIS assets will be aggregated when calculating thresholds, potentially resulting in different outcomes for some firms.

5. New AIFM Categories 

Firms will be required to determine whether they fall within the Small, Medium or Large AIFM category and notify the FCA accordingly. The proposed thresholds are based on aggregate NAV:

  • Small AIFM: Below £750 million
  • Medium AIFM: £750 million to £5 billion
  • Large AIFM: Above £5 billion

6. New and Removed Exemptions

Some internally managed UK investment trusts may fall outside the FCA authorisation perimeter where specific conditions are satisfied. Conversely, the removal of the small registered AIFM exemption may bring certain UK property scheme managers within the regime. Existing exemptions for SEF and RVECA managers remain, although FCA supervisory powers will be enhanced.

7. Policies and Procedures Will Require Review

The introduction of the new FCA sourcebook (ALTS), alongside consequential handbook amendments, including SYSC. Firms will need to review policies, procedures, governance frameworks and compliance documentation to ensure continued alignment with regulatory requirements.

8. Fund Operations and Management

Large AIFMs are unlikely to experience significant operational disruption. However, firms falling within the Small and Medium categories may benefit from a less prescriptive framework for areas such as valuation, liquidity management and risk oversight. For many existing sub-threshold AIFMs, the focus may be on formalising existing arrangements rather than introducing entirely new processes.

9. Governance Expectations May Increase

Firms moving from sub-threshold status into the new regime may need to strengthen governance arrangements, oversight frameworks and documented controls, even where operational practices are already robust. 

10. Opting into the Large AIFM Regime Is a Strategic Decision

Firms qualifying as Small or Medium AIFMs will have the option to elect into the Large AIFM regime. This decision should be considered carefully, taking into account investor expectations, distribution considerations and wider commercial objectives.

11. FCA Reporting

Changes to FCA reporting will apply across the board. Firms should review the proposed reporting framework, data requirements and submission obligations to understand the operational impact and implementation effort involved.

12. The Remuneration Framework Becomes More Proportionate

Remuneration requirements will be scaled according to firm size. Large AIFMs will remain subject to the most comprehensive requirements, while Small and Medium AIFMs will benefit from a more proportionate approach. Firms should assess the impact on remuneration policies and governance arrangements.

13. Audit Obligations Will Differ by Category

Only Medium and Large AIFMs will be required to ensure that their funds are audited under the proposed regime. This may reduce costs and administrative burdens for some smaller managers.

14. Investor Disclosure and Reporting

New disclosure obligations will apply across the regime. The framework is largely principles-based, although additional protections and requirements will apply where retail investors are involved.

15. Regulatory Capital

The FCA intends to consult separately on regulatory capital requirements. While the final position remains uncertain, some firms transitioning into the Small AIFM category may face higher capital expectations than under the current regime.

16. Depositary Requirements

Only Medium and Large AIFMs will be required to appoint a depositary. Firms moving into the Small category should assess whether retaining existing depositary arrangements remains commercially and operationally appropriate.

17. CIS Operator Obligations

Historically, FCA fund-level conduct rules have had limited application to CIS operators. Under the proposals, CIS operators will become subject to defined disclosure and reporting requirements unless a specific exemption applies. Certain vehicle types, including carried interest vehicles, joint ventures vehicles, single-investor vehicles and employee participation schemes, may remain outside scope.

18. Delegation Arrangements 

The FCA is not proposing to restrict delegation arrangements. However, firms will need to demonstrate robust oversight, governance and challenge processes. The notification framework will also expand to include certain "core" functions in addition to existing investment management functions.

19. Valuation, Risk and Liquidity Management Become Core Themes

Valuation, risk management and liquidity oversight will become central regulatory considerations for all AIFMs. While Small AIFMs and managers of certain unleveraged closed-ended AIFs (e.g. property, venture capital, private equity) will benefit from a less prescriptive framework, firms should review whether their existing frameworks are sufficiently documented, evidenced and governed.

20. Start Planning Now

Although implementation remains some way off, the work required is significant. Classification exercises, legal analysis, governance reviews, policy updates, investor disclosures, reporting changes and strategic decisions are likely to require significant lead time. Early preparation will place firms in the strongest position to manage the transition efficiently.

While many details remain subject to consultation and further FCA guidance, the direction of travel is clear: a more proportionate, risk-based framework that applies across the alternative investment fund sector. Firms that begin assessing the implications now will be better positioned to navigate the transition and take advantage of the implementation period before the new regime comes into effect.
