Private equity, private credit and infrastructure investing have historically been the preserve of pension funds, endowments, and the wealthiest individual investors, typically requiring minimum commitments and lock-up periods that put them well out of reach for most people. That’s beginning to change in the UK, through a specific and fairly technical regulatory development worth understanding on its own terms.
The vehicle behind the shift: the Long-Term Asset Fund
The mechanism doing most of the work here is the Long-Term Asset Fund, or LTAF — a fund structure introduced by the Financial Conduct Authority specifically designed to let a broader range of investors access illiquid private-market assets, while managing the fundamental mismatch between illiquid underlying investments and investors who might want to withdraw money on shorter notice. LTAF assets have grown to around £7.3 billion, a meaningful figure for a still-relatively-new fund category, and the FCA has taken the further step in 2026 of permitting LTAF holdings within stocks and shares ISAs — meaning exposure to private markets can now, for the first time, sit inside one of the UK’s most familiar and widely used tax-efficient investment wrappers.
Why this matters beyond the technical detail
The practical significance is straightforward: private markets have, over long periods, offered a different risk and return profile from public markets, and access to that asset class has historically been one of the clearest advantages institutional and ultra-wealthy investors held over everyday savers. Widening that access, even partially and with real constraints attached, is a genuine structural change in what a UK retail investor with a stocks and shares ISA can hold, not merely a marginal product tweak.
The caveats are doing real work here, not just ticking a regulatory box
It’s worth being precise about what “more accessible” actually means in practice, because the FCA has built in deliberate friction rather than opening the floodgates. Retail investors accessing LTAFs and similar restricted mass-market investments still face risk warnings and appropriateness assessments before they can invest, and a cap limits unadvised retail investors to putting no more than 10% of their investable assets into this category of restricted investment. That’s a meaningful guardrail, reflecting the FCA’s own view that private-market investments carry real risks — illiquidity chief among them — that differ materially from a typical listed equity fund, and that most retail investors have limited experience assessing.
Illiquidity is the single most important practical difference for anyone considering this kind of exposure: unlike a typical fund holding listed shares, an LTAF’s underlying assets can’t be sold quickly, and funds structured this way typically build in longer redemption notice periods, sometimes lasting months, specifically because the underlying assets can’t be converted to cash on short notice. An investor treating an LTAF like a conventional ISA holding they can access whenever needed would be misunderstanding what they’ve actually bought.
Who this is genuinely relevant for
This shift is most meaningfully relevant to investors who already have a diversified core portfolio and are considering a modest allocation to a different asset class as a genuine diversifier — not as a replacement for more liquid holdings, and not as a way to chase higher headline returns without understanding the corresponding illiquidity and risk. The 10% cap on unadvised access is itself a signal from the regulator about how this should be sized within a typical portfolio, for those without professional advice guiding a different allocation.
How this compares with other countries’ approach to retail private-market access
The UK’s approach, through the LTAF structure with its built-in caps and appropriateness assessments, sits at a deliberately cautious point on the spectrum compared with some other markets. The United States, for instance, has moved further and faster in recent years toward retail access to private equity and private credit through various fund structures, in some cases with fewer explicit caps on individual exposure than the UK’s 10% limit for unadvised investors. Whether the UK’s more cautious, phased approach proves to be prudent risk management or unnecessarily restrictive relative to genuine investor demand is a live debate within the industry, with fund managers generally arguing for faster liberalisation and consumer advocates generally urging continued caution given how new this kind of access still is for most retail investors.
The due diligence challenge this creates for investors
One underappreciated practical challenge this shift creates: private-market investments are inherently harder for an individual investor to assess than a typical listed equity fund, since the underlying assets aren’t priced continuously by a public market and disclosure standards, while regulated, differ meaningfully from listed company reporting. An LTAF investor is placing more trust in the fund manager’s own valuation and reporting practices than a typical equity fund investor needs to, simply because there’s no independent, continuously updated market price to check that valuation against. This isn’t a reason to avoid the asset class, but it is a genuine additional layer of due diligence that private-market investing requires, relative to buying a well-known index tracker, and it’s part of why the FCA has built in the protections described above rather than opening full retail access without restriction.
What this article is not
This is a description of a regulatory and market-access development, not a recommendation to invest in LTAFs, private equity, or any other specific product. Private-market investments carry real risks, including illiquidity and the risk of loss, and are not suitable for every investor.
