UK Hedge Fund Setup Guide

Key Fact: Creating a hedge fund in the UK involves both structuring, which means creating a UK investment management entity and a dedicated fund vehicle, in order to comply with FCA requirements and achieve the most efficient tax planning.

Introduction

Creating a hedge fund in the UK implies having a solid background that will distinguish an investment management entity from the fund vehicle. The process of creating such a hedge fund requires going through the procedure of getting authorisation from the Financial Conduct Authority (FCA), as well as doing the right structuring and tax planning. In addition, it is important to be operationally ready in terms of prime brokerage, legal, administration, and compliance services. This guide gives comprehensive information on regulatory processes, management structures, offshore structures, and other aspects of launching a competitive global hedge fund business in the UK.

Understanding the Dual-Entity Structure of a UK Hedge Fund

The typical hedge fund structure for the UK involves a dual entity structure aimed at segregating operational risk and defining the parties’ responsibilities.

The UK Investment Management Entity

The UK investment management entity acts as an operating company that hires investment staff, oversees office space, makes investment decisions and executes business development activities.

The Fund Vehicle

The fund vehicle is responsible for collecting money from institutional and qualified investors. The fund vehicle holds the portfolio assets and takes the liability while protecting the operating company from trade risks.

How the Manager and Fund Vehicle Work Together

The manager and the fund vehicle are bound by an Investment Management Agreement (IMA), where the manager provides investment decisions and execution, and in turn the fund provides fees to the manager.

How to Obtain FCA Authorisation for a UK Hedge Fund

Getting regulatory authorisation is an important step in establishing a UK hedge fund.

Direct FCA Authorisation

Those who want to obtain authorisation directly have to make a Part 4A permission application through the FCA Connect portal, stating their operational resilience, financial resources, and compliance systems.

Small Authorised UK AIFM vs. Full-Scope AIFM

If the Assets Under Management (AUM) are below €100m (leveraged) or €500m (unleveraged with a 5-year lock-up period), a manager may register himself/herself as a Small Authorised UK AIFM. However, managers who exceed these thresholds are subject to the Full-Scope AIFM category, which involves higher capital requirements, appointment of the depositary and rules on remuneration.

UK Mind and Management Requirements

The FCA demands that there should be real “mind and management” in the UK. Key persons, senior management and compliance officers should be physically located in the UK and exercise their functions under the SMCR regime.

FCA Application Timelines

Review periods under the law can extend from 3 to 6 months for complete applications, although incomplete applications can take up to 12 months.

Using a Regulatory Host or Umbrella Platform

New fund managers can establish their hedge funds in the UK by employing a regulatory host or sandbox. This way, they can conduct trading as an appointed representative during the review of their complete application.

Choosing Between a UK LLP and a Limited Company

Determining the structure of the management entity requires deciding whether to form a Limited Liability Partnership (LLP) or Limited Company (Ltd).

Setting Up a Limited Liability Partnership (LLP)

LLPs have a tax-transparent nature that enables direct income distribution among partners and their personal taxation without corporate-level tax payment.

Setting Up a UK Limited Company (Ltd)

Ltd companies have the obligation to pay Corporation Tax on company income and keep the money within the business by using it as salary, bonus, or dividend payments to employees.

Tax Considerations and HMRC Anti-Avoidance Rules

HM Revenue and Customs regulate such rules as Salaried Member Rules (capital contributions, variable remuneration, and management) and Mixed Membership Rules in order not to avoid taxation inappropriately between the individual member and the corporate member.

How to Choose the Right Management Entity

LLP is beneficial for the partnership equity model, while Ltd is appropriate for managers who want to keep the money in the business.

Understanding Hedge Fund Structures and Offshore Domiciles

Structuring the fund vehicle depends on target investor tax status and geographical location.

Master-Feeder Fund Structure

The master-feeder structure allows investment capital to be raised from various categories of investors like US taxable investors (through US Feeder) and offshore/US tax-exempt investors (through Offshore Feeder) to feed into a single master fund.

Master Feeder Fund Structure

Stand-Alone and Parallel Fund Structures

Stand-alone funds are applicable to one-jurisdiction approaches, while parallel funds operate side by side to meet certain needs of sovereigns or institutions.

Choosing a Fund Jurisdiction

Favored jurisdictions include the Cayman Islands and British Virgin Islands (BVI) for international flexible pooling, and Ireland and Luxembourg for EU-compliant UCITS or AIFMD distribution.

Factors Influencing Jurisdiction Selection

Jurisdiction selection is influenced by target investor preference, tax treaties, regulatory costs, and the asset class approach.

Building a Hedge Fund’s Core Team and Service Provider Network

The ideal UK hedge fund structure is one with good internal governance and credible external service providers.

Key Internal Roles

Internal positions are usually those of the Chief Investment Officer (CIO) for strategy implementation, Chief Operating Officer (COO) for infrastructure support, and other positions of Compliance Officers (CF10/CF11).

Legal advisors provide offering memorandums (PPM), whereas prime brokers are involved in trade execution, margin financing, securities lending, and clearing.

Fund Administrators

A fund administrator calculates the independent Net Asset Value (NAV), maintains the investor registry, and performs the Anti-Money Laundering (AML) process for new investors.

Auditors and Tax Advisors

Auditors independently review the annual statements of the funds, whereas tax advisors provide advice on reporting in line with UK & cross-border FATCA/CRS regulations.

Operational Due Diligence

Institutional investors go through ODD on internal controls, IT infrastructure, and stability of vendors before committing money to the fund.

UK Hedge Fund Setup Costs and First-Year Operating Budget

Securing adequate capitalization is vital for a smooth operational runway.

Establishment costs normally fall between £100,000 and £250,000+, including legal structuring, regulatory consulting, FCA fee structure, and incorporation.

Recurring Operating Expenses

These recurring costs include salaries of staff, compliance monitoring software, market data, auditing fees, funds administration, and minimum prime brokerage.

Understanding Break-Even Assets Under Management (AUM)

Based on fee structure (for example, a 1.5% management fee), the majority of UK hedge funds need $50M to $100M AUM to achieve break-even.

Planning the Fund’s Financial Runway

Hedge fund founders will require 18 to 24 months of financial runway for the fund before increasing AUM.
