British Business Bank boosts late-stage UK scale-up funding

The British Business Bank has invested more than £600 million directly in more than 50 UK science and technology scale-ups, marking a sharp increase in the state-backed lender's late-stage investing activity.

Direct equity investments have more than doubled from £290 million in October 2025 to more than £600 million, with more capital deployed in the past nine months than in the previous four years combined. The direct equity portfolio has grown from 31 companies in March 2025 to more than 50.

The expansion is part of a broader effort to address gaps in Britain's late-stage funding market, where high-growth businesses have often looked overseas for larger rounds of capital. The bank is on track to invest more than £400 million a year through direct equity under a plan to commit £2 billion over five years.

Since making its first direct equity investment in Quantexa in 2020, the institution has built a portfolio spanning life sciences, deeptech, advanced manufacturing, clean energy, defence, artificial intelligence and fintech. Those are sectors policymakers and investors see as strategically important to the UK economy.

Latest figures also show a marked rise in deal activity. The bank completed 18 new investments and 18 follow-on investments in the 2025-26 financial year, compared with 12 investments the year before. Total investment rose 2.5 times year on year, from £75 million to £188 million.

The increase comes as ministers and public finance bodies seek to keep more scaling companies in Britain, while pension funds, insurers and other domestic institutions face pressure to commit more money to growth businesses. A longstanding concern in UK venture finance has been the relative scarcity of large domestic funding rounds for companies moving beyond the early stage.

The British Business Bank, the UK government's economic development bank, has become a more active participant in later-stage financing through its direct equity programme. The strategy envisages deploying about £2 billion a year into the UK venture capital market overall, with about 20%, or roughly £400 million, earmarked for direct equity deals.

Under the model, the bank expects to make between 14 and 18 new investments a year. Initial cheque sizes typically range from £10 million to £40 million, with cumulative investments over time reaching up to £75 million.

Capital gap

The bank has framed the expansion as a response to structural weaknesses in the UK funding landscape. Britain has produced a steady flow of venture-backed companies in areas such as AI, life sciences and financial technology, but many founders and investors argue that the market still lacks enough later-stage capital to support growth at home.

The issue has fueled a broader debate about how to capture more of the economic value generated by British research and start-ups. Public policy has increasingly focused on whether promising domestic firms can remain headquartered in the UK and expand rather than shift abroad as they mature.

"Supporting UK scale-ups is a national economic imperative. The UK excels at creating businesses, but our domestic capital base has yet to match our scientific excellence. Our activity should be interpreted as a clear signal to UK institutional capital that we want them to join us in backing UK scale-ups. We now have fuel in the tank and intend to put UK innovation in fifth gear," said Leandros Kalisperas, Chief Investment Officer at the British Business Bank.

The bank's direct equity team has also linked the larger annual target to the number of venture-backed businesses that are now reaching the stage where they need larger rounds. That shift has increased pressure on both public and private investors to provide later-stage support in a market where overseas capital has often played an outsized role.

"We are accelerating our ambitions to match the calibre of UK innovation. By investing £400 million per year into the most exciting venture-backed UK scale-ups across life sciences, deep tech, AI and fintech, we aim to act as an ecosystem multiplier and ensure the most innovative UK businesses have the capital and support to scale rapidly," said Charlotte Lawrence, Managing Director and Head of Direct Equity at the British Business Bank.

The government has presented the increase in direct investment as part of its industrial policy agenda, linking scale-up finance to economic growth and business retention in the UK.

"We are ramping up the pace and scale of investment, backing the UK's highest-growth scale-ups at a level not seen before through our modern industrial strategy. By more than doubling investment in just nine months, we're giving firms the firepower they need to stay and scale here in the UK and drive the economy," Peter Kyle, Business Secretary, said.
