VCTs and UK Tech Start-Ups: Potential, Costs and Key Rules

Venture capital trusts (VCTs) give investors a route to a varied group of young UK businesses, including technology firms that may be difficult to access through traditional funds. The opportunity comes with real trade-offs: these companies can take years to mature, some will fail, and VCT charges can be high. The tax benefits may help, but the case for a VCT should rest on its portfolio and manager as well as its reliefs.

Technology businesses are already in VCT portfolios

The UK may not have many household technology names on the scale of Google, but its start-up scene includes businesses with substantial valuations. Quantexa, a data, analytics and artificial intelligence software company founded about ten years ago, has been valued at $2.6 billion. Thought Machine, which develops cloud-based and AI tools for the banking industry, has reached a similar valuation. Insurtech company ManyPets has been valued at $2 billion.

Each of those businesses received VCT funding in its earlier years. Other VCT-backed companies are working in areas such as AI-assisted gene editing for agriculture, satellite and orbital tracking, and digital content. The Association of Investment Companies reports that VCTs made 25 investments in British AI businesses over the three years covered by its research. The sector’s activity also reaches software, financial technology, cybersecurity and the internet of things.

That breadth is part of the appeal. VCTs were created in 1994 to help channel money into early-stage UK companies with room to grow. Their portfolios can include businesses beyond technology, too: earlier success stories have included property website Zoopla, food-delivery company Gousto and clothing marketplace Depop.

Tax relief has fallen, while other rules have expanded

For shares issued from 6 April in the tax year described here, upfront income-tax relief is 20%, down from 30%. The annual investment limit is £200,000, so investing that full amount in qualifying new shares could reduce the net cost to £160,000, assuming the investor can use the relief in full. Shares must be held for at least five years to keep it; selling earlier means the relief must be repaid.

The lower rate has affected fundraising. Wealth Club chief executive Alex Davies said fundraising in the 2025–26 tax year nearly reached record levels as investors moved to use the higher rate before it changed. The following tax year, 2026–27, had been slower at the time of reporting. Davies said three established VCTs that began offers from September had each raised more than 70% less than at the same point in the prior year. These figures describe fundraising at that time, rather than a forecast of how the full year will finish.

There are other VCT tax features to weigh. Dividends and capital gains from VCT shares are tax-free, and don’t need to be reported on an annual self-assessment return. VCTs do not provide an inheritance-tax benefit. The reliefs are only one part of the decision: a tax advantage can’t make a weak portfolio or unsuitable risk level a good fit.

Some investment rules have also widened the pool of companies VCTs can back. The maximum company size cited for eligibility rose from £15 million to £30 million. VCTs can invest up to £20 million in an individual company, with a higher limit of £40 million for knowledge-intensive businesses. The source describes the earlier per-company limit as £10 million. These changes may let funds support more mature businesses and take part in later fundraising rounds. They may also give fast-growing companies more room to raise capital from existing backers.

Early-stage exposure means a long, uneven journey

A VCT’s appeal depends on the businesses it can select and how carefully it spreads its holdings. Managers may assess large numbers of companies before making a small number of investments. Pembroke chief executive Andrew Wolfson described a process in which a manager might meet 1,000 companies and invest in as few as ten. The aim is to identify strong founders and promising ideas early, but even skilled selection can’t remove the chance of failure.

Returns can take much longer than a few years to emerge. A handful of standout holdings may account for much of a fund’s gains, while weaker businesses weigh on results. Diversification across early-stage companies can soften the effect of an individual setback, but it doesn’t prevent losses. The collapse of Honest Brew, for example, cost one VCT more than £3 million.

Fund results can differ widely, so comparing managers matters. Past performance can help show whether a team has experience raising money, selecting companies and completing exits, though it can’t guarantee future results. A manager’s history may also offer clues about its network and access to potential investments. For an existing fund raising more money, investors can examine its current holdings: how developed are the businesses, how are they performing, and how widely spread is the portfolio?

VCTs can also return income from successful company sales. Managers may not distribute all sale proceeds immediately, so check the fund’s approach to dividends and realisations. Fees deserve the same attention. Annual charges may reach 3.5%, and some funds add performance fees. Where a performance fee is calculated using estimated net asset value, that figure reflects a valuation of holdings rather than cash realised from a sale. Read how charges are calculated and when they apply.

Choose the fund type and timing with care

VCTs vary in focus. A generalist fund may spread holdings across industries and could suit someone building an initial VCT position. Some funds also invest in companies listed on Aim. Davies recommends starting with established, diversified VCTs before looking at newer funds. Investors who already hold several generalist funds might consider whether a specialist portfolio adds useful variety; options in the market include software, healthcare, digital businesses and companies addressing social challenges.

Some VCT managers offer early-bird discounts to encourage investors to commit earlier in the tax year. These offers can reduce the initial cost, but they shouldn’t decide which fund to buy. Compare the portfolio, manager, charges and distribution approach first. Around 15 managers had begun marketing new funds or share issues in existing funds during the 2026–27 tax year described here. Offers can close once a fund reaches its target, so anyone considering a VCT should check the current terms and availability.

VCTs may suit people who understand that early-stage company shares can be difficult to value and sell, and who can leave their money invested for the long term. The practical starting point is to assess the underlying businesses, the manager’s record, the full fee structure and the five-year holding requirement. Tax relief can improve the arithmetic, but patience and tolerance for setbacks remain central to the decision.
