Angel investing offers an exciting opportunity for individuals – angel investors – to directly support innovative early-stage companies, combining potentially high financial returns with real-world impact. But what exactly does it mean to become an angel investor (or business angel), how do you get started and why join an angel investor community like Oxford Innovation Finance’s OION Angel Network?
In this article, we explore the key tax incentives and benefits of angel investing, and how joining a UK angel investor group can enhance both your investment experience and the success of the startups you back.
What is angel investing?
Angel investing refers to the practice where high-net-worth individuals (HNWIs) invest personal capital into early-stage startups in exchange for equity ownership (i.e. a share of the business). Unlike traditional investment funds, angel investors often contribute not just money, but also strategic guidance, industry expertise and valuable contacts to help young companies grow and succeed. Angel investing is inherently high-risk, high-reward, and typically involves a long-term investment horizon as startups develop and scale.
Five key benefits of angel investing:
1. Potential for significant financial returns
One of the most cited reasons investors consider angel investment is the potential for significant financial upside. Because investments are made at early stages, often when company valuations are lower, successful exits can result in returns that outperform many traditional asset classes. Investors typically receive equity stakes, giving them ownership in the companies they back and the opportunity to share in future growth and profitability.
2. Tax incentives and financial support structures
In the UK, government-backed schemes like the Enterprise Investment Scheme (EIS) and the Seed Enterprise Investment Scheme (SEIS) provide tax reliefs to qualified angel investors. These incentives help to mitigate some of the inherent risks of early-stage investing by offering income tax relief and potential capital gains exemptions when certain conditions are met.
3. Diversification and portfolio building
Angel investment enables diversification beyond traditional public markets. By allocating a portion of capital into evolving startups across sectors, investors can build a broader, more dynamic portfolio. Joining an angel investor group or angel community further enhances diversification opportunities by providing exposure to curated deals alongside other experienced investors.
4. Mentorship and active contribution
Unlike passive investments in stocks or mutual funds, angel investing invites active involvement. Many angel investors find satisfaction in mentoring founders, offering strategic advice, and leveraging their own professional networks to help startups navigate challenges. This approach can significantly influence a young company’s growth trajectory.
5. Access to a vibrant angel investor community
An active angel investor community can amplify the benefits of individual investing. Networks like Oxford Innovation Finance’s Oxford Investment Opportunity Network (OION), connect investors with high-quality, pre-screened startups and provide ongoing support through regular pitch events, networking opportunities and detailed investment resources.
How to become an angel investor in the UK?
To become an angel investor, you can start by joining a reputable angel investment network like the OION angel network, where you’ll gain access to pre-screened investment opportunities in promising early-stage companies and support during the investment process.
In terms of eligibility criteria, The Financial Services and Markets Act 2000 requires investors to be self-certified as Sophisticated Investors or High Net Worth Individuals. You can downland and complete the High Net Worth Individual Investor statement or the Sophisticated Investor self-certification statement on the Oxford Innovation Finance website or on the UK Business Angels Association (UKBAA) website.
Before making your first investment, it is worth talking to other investors, observing pitch events and thinking about your risk appetite. You may also wish to undertake the UKBAA’s online learning course for new angel investors.
