Private Equity: Benefits of UK Reserved Investor Fund Structure

20 November 2025


What Are the Key Points to Consider

  • Fund wrapper vs Lux SARL/Irish s110 DACs: A UK Reserved Investor Fund (UKRIF) is a UK regulated on-shore professional fund. A Lux SARL, Irish s110 DACs (and similar EU designated investment company structures) are better suited as a corporate SPV HoldCos or feeders; using it as the fund itself adds cost, complexity and investor relations risk.
  • Faster launch: UKRIFs follow standard UK fund workflows and documents and do not require any regulatory or tax clearance or approval.
  • Administrator and Operational Reporting fit: UKRIF operations align with London service providers, tax analysis and UK substance narratives.
  • Joined‑up UK toolkit: The UKRIF fund is joined-up with on-shore, UK asset‑holding regimes and are designed to work together.
  • Strategy ready: UKRIFs can accommodate capital calls, staged closings, hybrid liquidity and bespoke fees without retail drag.
  • EU Distribution: If full EU passporting is needed then a Lux corporate wrapper (e.g. a Lux RAIF) can be used for full EU passporting if other private placement exemptions are not available.
  • Lower execution risk: UKRIFs concentrate governance in the fund documents itself. SARLs/DACs require corporate constitutions, shareholder agreements and AIFM/depositary layers to replicate a fund.

Why a UKRIF Beats a SARL/DAC for Institutional Strategies

Choosing the right vehicle determines investor traction, operational friction and speed to market. A UKRIF is a dedicated fund wrapper for professional investors with a FCA regulated Alternative Investment Fund Manager and a UK resident Depositary or a Nominee.

What the UKRIF Is Optimised to Do

RIFs are built for alternatives – private equity, credit, real estate (with no maximum real estate exposure restrictions), secondaries and hybrids – without retail burdens that slow launch, require regulatory approval and inflate cost. Managers get a UK‑domiciled fund, a familiar London service ecosystem and tax and governance that investors recognise.

Asset Holding Companies

UK asset‑holding companies (rather than off-shore or Channel Islands) can be used to improve tax efficiency and substance narratives. The result is an onshore fund that is easy to explain to committees, reduces set-up, build-out, governance and reporting costs and independent off-shore directors.

Practical Advantages of a UKRIF

UKRIFs come with fund‑native governance on day one – investor eligibility, valuation, conflicts and reporting in a format fund managers and professional investors expect. Service providers know the playbook, which shortens setup and reduces execution risk. The UKRIF also aligns with UK substance (particularly if senior decision makers are London‑based), eliminates the reputational risk arising from utilising off-shore structures when investing in UK sensitive assets (such as infrastructure and real estate) and integrates cleanly with the UK asset holding company regime and carried‑interest ecosystem.

EU Marketing and Investor Access

UKRIFs suit UK and global professional investors and can still access EU professional investors via the National Private Placement Regime.

Cost, Documentation and Execution

A SARL/DAC is quick to incorporate and well-trodden (if expensive with Lux/Irish advisers), but the true comparator is the full package required to run a proper tax transparent fund. UKRIFs concentrate terms in familiar fund documentation – offering materials, management agreements, valuation and liquidity mechanics – reducing negotiation cycles. A SARL “as fund” adds corporate constitution, regulator approval, shareholder agreements, AIFM/depositary arrangements and governance policies, each a potential point of failure or misalignment. In practice, UKRIFs deliver shorter time to launch and lower establishment costs.

Private Equity Portfolio Features, Secondaries and Exits

UKRIFs comfortably support private markets features for professional and/or sophisticated investors including capital call structures, staged closings, hybrid or gated liquidity, in‑kind distributions and bespoke fees. They can also be drafted with secondary and continuation mechanics familiar to UK advisers and administrators, smoothing GP‑led processes. SARLs/DACs can be made to work, but variability in entrenched corporate rights, capital maintenance regimes and consent thresholds often slows secondaries and transfers.

When a SARL/DAC Still Makes Sense

Use a corporate where it excels: portfolio SPVs, co‑investment sleeves, feeders beneath a main fund, or EU‑centric stacks where the fund sits elsewhere, and the corporate is a holding layer. If you need EU passporting, opt for a Luxembourg fund wrapper rather than making the SARL act as the fund.

Bottom Line

For an institutional tax transparent fund aimed at professional investors, the UKRIF offers a clearer narrative, faster launch, tighter governance and better operational fit than a SARL/DAC repurposed as a fund. Keep the SARL/DAC in the holding stack and let the fund be a fund.
