Social Impact Investing in the UK | Top Trends, Companies & Funds

| Hannah Skingle

Social impact investing is a strategy through which individual investors, angel syndicates, venture capital or private equity funds seek a positive social or environmental impact, as well as a financial return. Over the last decade, impact investment has become an increasingly popular avenue of deploying capital, satisfying investors’ desires to have a social purpose whilst making monetary gains. In this article, we’ll look at the state of impact investing in the UK, who the most active and prolific impact investment funds are in the space, as well as the trailblazing companies that they’ve funded.

Classifying social impact investment

Of course, a ‘positive impact’ means different things to different people, so it’s difficult to establish a precise classification. For the sake of this article, we’ve focussed on intent and purpose; we’ve included funds that have explicitly stated that the social impact of a company is central to investment decisions, rather than funds whose social impact and environmental benefits are a byproduct of their philosophy or sector restriction. 

In accordance with EQ Investors, we’ve also only picked funds that are investing in companies whose products and services are making a positive impact. This excludes those who operate in an ethically, environmentally and socially responsible manner, regardless of the purpose of their products and services (commonly known as ESG investing).

Impact funding over time: an emerging community of responsible investors

Impact investment activity has been steadily increasing over the past decade. The Global Impact Investing Network (GIIN) 2020 Annual Impact Investor Survey estimates a current global market size of $715b. Within the UK’s private market, a peak of 51 deals were made in 2019 at a value of £86.4m. We expect impact investing to become more popular as we come to understand more about the ways humans are negatively affecting the planet and what we can do to reduce this impact, as well as the many varieties of social inequality.

With that said, the impact investment market has not been exempt from the coronavirus slow down. In fact, it’s been hit harder than the rest of the equity investment market. 

We’ve seen a 25% drop in the number of announced equity deals completed by UK funders into UK companies between 01/01/2020  – 20/06/2020 and the same period last year. Meanwhile, we’ve seen a 37% drop in the number of announced deals made by impact funds across the same period. 

Of course, the sample sizes differ massively here, so it’s difficult to establish an accurate comparison. Since the outbreak of COVID-19, most institutional investors have doubled down on supporting their existing portfolio. With relatively few companies backed by social impact funds, it seems reasonable to expect a sharper drop in deal numbers.

The effect of COVID-19 on UK impact investing

Despite the slowdown, we expect the impact investing market to show increased activity in the wake of COVID-19, as investors mobilise cash to help the economic recovery of the country, and rectify the social issues and inequalities that have been exacerbated by the pandemic. Fund manager Triple Point has already set up a Kick Start fund to help early stage businesses that have yet to raise funding, which will sit alongside its Impact EIS fund.

Social impact investments are less likely to fail than conventional investments

Impact investing means supporting companies that align with investors’ moral and ethical viewpoints. But it would be a mistake to think it’s a charitable pursuit, and the financial returns are not to be understated. 

Indeed, companies that received investment in the Seed or Venture stages of evolution are half as likely to have ceased trading if they were backed by a social impact investor. They are also slightly less likely to have progressed to further stages of evolution, or to have exited the private market through an IPO or acquisition. This indicates that impact investors have a longer exit horizon than conventional funders.

So who are the most active funders in the space? Our data shows that Ascension Ventures has completed the most announced fundraisings (54) into UK impact ventures, followed by Nesta Impact Investments (41).

More recently, NIV’s strategy is focussed on making initial investments, between £500k and £1m, in companies operating within three priority themes of interest; education, healthcare and UK government innovation. Companies will also need to meet a number of other criteria including an emerging sustainable business model, a commitment to impact by incorporating impact measurement and impact reports into everyday decision making, and early evidence of product-market fit.

Clearly Social Angels (CSA)

Managed by the impact investment bank ClearlySo, CSA is the UK’s leading group of high-net-worth individuals and families focused on responsible investment. The network typically invests between £300k and £1.5m into seed and venture-stage companies.

Top companies backed by social impact investors


BBOXX is on a mission to solve energy poverty through the provision of clean, renewable energy solutions to communities with unreliable electricity supplies. The company currently supplies pay-as-you-go solar power, and is expanding to provide other vital utilities, such as access to water and the internet. In doing so, it is directly contributing to SDG 7 of the UN’s Sustainable Development Goals (ensuring access to affordable, reliable, and sustainable energy for all).  

Co-founders Mansoor Hamayun, Chris Baker-Brian and Laurent Van Houcke established the company in 2010, spinning out from Imperial College London. A decade later, BBOXX has grown to over 800 employees and is operating in 12 countries, including Rwanda, Kenya, Togo, DRC and Pakistan. The company is now in its Growth stage of evolution, and has received £107m in equity funding over ten rounds. It has an impressive roster of investors, including Ceniarth, Engie New Venture, and Mitsubishi Corporation


Featurespace profiles online customer activity in order to predict future behavior of individuals. This might sound more like a marketing tool than a traditional impact venture, but the benefit comes from the use of its data to make the world a safer place. The analytics software is used to prevent and intercept online fraud by spotting criminals through behavioural anomalies. 

Founded by David Excell, a graduate of Information Engineering at Cambridge university, Featurespace is now led by CEO Martina King. The company has featured on numerous high-growth lists, including the Deloitte Fast 50 and The Queen’s Awards for Innovation, and attended the prestigious Future Fifty accelerator programme in 2018.  

To date, the team has raised £83.5m over eight funding rounds, drawing on a number of different types of funds including angel syndicates (Cambridge Angels, Cambridge Capital Group), venture capitalists (Highland Capital Partners), not-for-profits (Nesta Impact Investments) and specialist commercialisation funds (IP Group).


Bulb supplies green energy to businesses and households through renewable sources, helping society work towards a more sustainable future. The company supplies 100% renewable electricity from solar, wind and hydro sources, as well as 100% carbon neutral gas. Bulb offsets the emissions from the gas it supplies by supporting carbon reduction projects around the world to tackle climate change. 

Co-founded by Hayden Wood (CEO) and Amit Gudka, the sustainability company is now in its Growth stage of evolution. To date, Bulb has secured £65.3m over six rounds of equity finance, the bulk of which (£60m) was raised in June 2018, at a pre-money valuation of £351m. Investors include Clearly So Angels (CSA) and JamJar Investments. 

As one of the UK’s best known social enterprises, Bulb has certainly shown rapid growth. In 2019, it reported a turnover of £823m, claimed to have over 1.6m customers and employed 550 people in London. The company has confirmed that it’s still hiring through the coronavirus pandemic. By now, we anticipate that Bulb is well into unicorn status, but will only be able to confirm a $1b+ valuation at its next funding round or exit event.

It does this by offering businesses in the UK and USA access to a cloud-based, on-demand workforce.

Now in its Growth stage of evolution, CloudFactory has secured £59.5m over five funding rounds. Investors include the Social Entrepreneurs Fund (managed by Bridges Fund Management), Nepali fund Dolma Impact, and The Rockefeller Foundation.
