How Private Equity Funds Work in the UK?

Explanation
The Structure and Mechanics of Private Equity Funds
The global private equity (PE) industry—now managing billions of dollars each month—is often seen as a hallmark of 21st-century capitalism. Over the past few decades, it has grown exponentially and today includes thousands of specialist firms operating across different strategies (venture, growth, mid-market, large buyouts) and regions.
At its core, the private equity model is built on two key activities: raising capital and investing it in businesses. For investors, the appeal lies in the potential to outperform traditional asset classes. PE also plays a transformative role by providing capital to support restructurings, business turnarounds, innovation, or expansion.
Fund Formation and Capital Raising
Most private equity firms begin life as a limited liability partnership (LLP), raising capital from institutional and high-net-worth investors. The typical private equity fund is a closed-end vehicle with a lifespan of around 10 years.
Funds are marketed through internal investor relations teams or third-party placement agents. A Private Placement Memorandum (PPM) outlines the fund’s investment strategy, sector focus, expected returns, manager track record, and fee structure.
Fund sizes vary significantly—from small VC funds of a few million dollars to mega-funds exceeding $10 billion, such as those managed by Blackstone, Carlyle, KKR, and TPG.
Who Invests in Private Equity?
Private equity fund investors are known as Limited Partners (LPs). These include:
- U.S. state pension plans (a major capital source historically)
- Insurance companies and banks
- University endowments
- High-net-worth individuals
Retail investors have limited access, although public vehicles like 3i in the UK or listed entities by Blackstone, KKR, and Apollo have expanded access in recent years.
Fund Lifecycle: From First Close to Exit
The fund’s life begins with the “first close”, when enough commitments are secured to begin deploying capital. Multiple closes may follow before the final close concludes fundraising.
The first phase of a fund is the investment period—typically up to five years—during which the General Partner (GP) sources and executes deals. GPs rarely allocate more than 10% of the fund to a single deal to maintain diversification.
How Investments Are Financed
In buyouts, deals are usually financed with a mix of equity and debt—often one part equity and three to four parts debt. Some LPs also participate in co-investment opportunities.
PE firms seek controlling stakes and partner with management teams to restructure, grow, or expand the company through bolt-on acquisitions. In contrast, venture capital deals tend to be 100% equity financed and held for longer durations due to the higher risk and lack of financial history.
Exit Strategies
Private equity firms look to exit investments after 3–5 years (or more), aiming to generate returns through:
- Sales to strategic buyers or other PE firms
- Initial Public Offerings (IPOs)
- Dividend recapitalizations through new debt issuance
Revenue Model: Fees and Carried Interest
GPs earn revenue through:
- Management fees: Typically 1%–2.5% annually on committed or invested capital
- Carried interest: Usually 20% of profits, paid only after investors receive their committed capital back plus a hurdle return (often around 8%)
- Monitoring and transaction fees charged to portfolio companies
Management fees are front-loaded (years 1–5) and then typically step down. Carried interest is calculated on a whole-fund basis or deal-by-deal, depending on the fund structure.
Some funds must return all LP capital and fees before carried interest is paid out. This aligns GPs’ incentives with long-term fund performance.
Final Thoughts
Private equity’s appeal lies in its active ownership model and long-term value creation strategies. As the asset class matures, innovation in fund structures, access mechanisms, and investment approaches continues to reshape the market globally.

The Origins and Evolution of Private Equity
Private equity (PE) has grown into a global financial powerhouse, but its beginnings can be traced back to the post-World War II era. The formation of the American Research and Development Corporation (ARDC) in 1946 marked one of the earliest institutional private equity efforts.
ARDC’s mission was to fund companies that could repurpose wartime technologies for commercial use. One of its landmark investments was in Digital Equipment Corporation (DEC). A modest $70,000 investment in DEC eventually turned into $355 million, delivering a return of over 5,000 times the original amount. This staggering success demonstrated the potential of private equity to fuel innovation and drive extraordinary financial outcomes.
The Rise of Leveraged Buyouts in the 1980s
The 1980s became a transformative decade for private equity, largely due to the emergence of leveraged buyouts (LBOs). Pioneering firms such as Kohlberg Kravis Roberts (KKR) led this movement, acquiring companies primarily through borrowed capital, implementing operational improvements, and exiting through strategic sales or IPOs. These deals often resulted in significant returns and played a key role in legitimizing private equity as a powerful tool for value creation.
Private Equity Today: A Global Asset Class
Fast-forward to today, and private equity has evolved into a multi-trillion-dollar global industry. PE firms are actively involved in reshaping key sectors, including technology, healthcare, financial services, energy, and consumer goods. The United States continues to dominate the market, but institutional investors are increasingly turning their attention to opportunities in Europe and Asia where valuations are more attractive and growth potential remains robust.
In recent years, PE has also embraced thematic and impact investing. Many funds are aligning their strategies with ESG (Environmental, Social, and Governance) principles or specific global trends, such as digital transformation, renewable energy, and health innovation. This not only broadens investor appeal but also enhances the sector’s influence on global progress.
The Dominance of Private Companies
One compelling statistic underscores the importance of private markets: approximately 83% of U.S. companies with over $100 million in revenue remain privately held. This highlights the vital role of private equity in financing, developing, and scaling enterprises outside the public markets.
In summary, private equity has evolved from a niche investment strategy to a dominant force in global finance. With its origins in innovation and a future driven by strategic investment, operational excellence, and global diversification, PE is positioned to remain a key player in shaping tomorrow’s economy.
