From helping ambitious businesses turn innovative ideas into commercial reality to giving investors the opportunity to support the next generation of UK growth companies, Enterprise Investment Scheme (EIS) investment plays an important role in the UK ecosystem, and innovation rarely happens without investment.
For an early-stage company developing a new technology, access to capital can make the difference between an idea remaining on the drawing board and becoming a scalable business. Yet investing in young, innovative companies comes with significant risk. These businesses are often pre-profit, developing new technologies and operating in markets that are still emerging. This is precisely why EIS Funds exists, to encourage private investors to provide capital to some of the UK’s most ambitious growing companies. And the need for that investment remains significant.
EIS Funds are helping channel private capital into ambitious UK businesses. The latest HMRC statistics show that around £1.58 billion was raised through EIS in the 2024/25 tax year, demonstrating the continuing importance of private investment in supporting early-stage businesses. Within that total, 1,145 companies raised EIS investment for the first time, collectively raising around £333 million. These aren’t simply numbers on a tax return. Behind them are businesses developing new technologies, creating jobs, commercialising research and addressing some of the major challenges facing the UK and global economy.
The Government has also recognised that the capital requirements of innovative companies have changed. From April 2026, the limits on the amount companies can raise through EIS were increased, with the annual investment limit rising to £10 million for most companies and £20 million for knowledge-intensive companies. Lifetime limits were also increased. The message is clear, innovative companies need access to more growth capital, and private investment has an important role to play.
What does EIS mean for companies?
For an ambitious early-stage business, securing investment is about much more than putting money into the bank. EIS investment can provide the capital needed to:
- develop and commercialise new technology
- recruit specialist talent
- accelerate product development
- enter new markets
- build sales and marketing capabilities
- undertake research and development
- secure follow-on investment
- move from early validation towards commercial scale.
Just as importantly, bringing experienced investors onto a company’s shareholder base can provide access to knowledge, networks and strategic support. At Oxford Innovation Finance, this is a key part of the investment approach.
Our experience is that the most valuable investors do more than provide capital. They can challenge assumptions, open doors, introduce potential customers or partners and help founders navigate the decisions that come with scaling an ambitious business.
Recent investments demonstrate the breadth of companies that EIS capital can support. Semarion, a University of Cambridge spin-out developing cell assay technology designed to improve drug discovery workflows, received investment from the Oxford Innovation EIS Growth Fund alongside OION angel investors in 2026.
HoxtonAi, an AI-powered spatial intelligence company, has also received additional investment from the EIS Growth Fund and OION Angel Network to support its international growth.
These examples illustrate an important point, EIS investment isn’t about backing one particular sector or type of business. It can help ambitious companies across science and technology access the capital they need to progress.
What does EIS mean for investors?
Relationships must work both ways. Investors provide vital capital to early-stage companies, but EIS is designed to recognise the additional risk involved in investing in smaller, unquoted businesses. Subject to eligibility and individual circumstances, EIS investments offer investors a number of tax incentives, including 30% Income Tax relief on qualifying investments, Capital Gains Tax advantages and loss relief. For investors, this can make EIS an interesting component of a broader investment strategy. But the attraction isn’t purely about tax.
Investing in early-stage businesses provides an opportunity to participate in the development of companies working on new technologies, products and services, and potentially to support businesses that could become significant employers, exporters and contributors to the UK economy. It can also provide something that isn’t always available through traditional investments, a direct connection with the businesses being backed.
For those who want to invest across a number of companies, an EIS Growth Fund can provide diversification. Oxford Innovation Finance’s current EIS Growth Fund, for example, provides investors with a portfolio of 6–12 innovative UK science and technology companies, with investments deployed over 12–18 months.
Why does EIS matter now?
The case for early-stage investment extends beyond individual companies and investors. The UK has considerable strengths in areas including life sciences, AI, deep technology, climate technology and advanced engineering. But developing world-class technology is only part of the challenge. Businesses also need the capital to commercialise, grow teams, enter international markets and scale.
Recent investment activity reinforces the importance of this challenge. In June 2026, the British Business Bank announced that it had invested more than £600 million directly into more than 50 UK scale-ups, describing its activity as part of an effort to address longstanding gaps in the UK’s growth capital market and help high-growth companies scale and remain in the UK.
EIS investment operates earlier in that journey, helping to create the foundations from which future scale-ups can emerge. It is therefore part of a much bigger investment ecosystem, connecting private capital with entrepreneurs at a stage when access to funding can have a particularly significant impact.
A positive cycle of investment and growth
The most compelling argument for EIS is perhaps the simplest. Investors provide capital. Companies use that capital to grow. Growing companies create jobs, develop technologies, generate economic activity and attract further investment. Investors, in turn, have the opportunity to benefit if those businesses succeed. That creates a positive cycle.
For founders, EIS investment can make it possible to take the next step in their growth journey. For investors, it provides an opportunity to put capital to work in some of the UK’s most ambitious businesses, with tax incentives designed to help compensate for the risks associated with early-stage investing. And for the UK, it helps connect private investment with innovation, entrepreneurship and economic growth.
At Oxford Innovation Finance, we see the impact of this relationship every day. Since launching in 2021, the Oxford Innovation EIS Growth Fund has supported a diverse portfolio of innovative companies across the UK. The latest fund, launched for the 2026/27 tax year, continues that approach, providing investors with access to a diversified portfolio of early-stage and high-growth science and technology businesses.
But successful early-stage investment is about more than identifying promising companies. It is about supporting founders through the difficult stages of building a business, providing capital alongside experience, networks and connections, and helping companies establish the foundations they need for sustainable long-term growth.
For investors, that means an opportunity to do more than invest in a portfolio. It means backing innovation, supporting ambitious founders and helping build the businesses that could shape the UK’s future. The Oxford Innovation EIS Growth Fund for the 2026/27 tax year is currently open for investment.
Investments in unquoted companies are high risk, and investors may lose some or all of their investment. EIS tax reliefs are subject to individual circumstances and qualifying conditions and may change. Oxford Innovation Finance does not provide investment, tax or legal advice and recommends that investors seek independent professional advice. Past performance is not a reliable indicator of future results.
