The UK finance gap in 2026 is sharpest at seed stage. Smaller UK businesses raised £12.3 billion of equity across 2,002 deals in 2025, only 4% less money than in 2024, but deal numbers fell 17% and seed-stage deals fell 27%, according to the British Business Bank's Small Business Equity Tracker 2026. Seed companies also took longer to raise.
In other words, the money is still there, but it is going to fewer, larger and later-stage companies.
Where the money went
- Growth stage: investment rose 10% to £5.7 billion, even though deal numbers fell 4%.
- Big rounds: the ten largest fundraisings took 23% of all smaller-business investment, the highest share since 2020.
- AI: a record £5.4 billion, 44% of the total value and 26% of deals.
- US comparison: adjusted for the size of the economy, UK venture investment was 32% below the US over 2023 to 2025.
The early signs for 2026 were mixed. Equity going to smaller businesses fell 43% in the first quarter of 2026, while total UK equity rose 28%, driven by three very large deals worth about £3 billion.
The regional picture
London's share of investment value fell from 60% to 57%, and its share of deals from 49% to 48%. Several regions grew fast from a smaller base:
- South West: investment value up 104%;
- North West: up 82%;
- Scotland: up 74%.
These are big percentage rises on small totals, so one or two large deals can move them a lot.
New funds should help, mostly later
UK venture capital firms raised a record $6.9 billion of new funds in the third quarter of 2026, according to HSBC Innovation Banking and Dealroom data reported by DIGIT. That is money to invest over the next few years. However, most of it went to large managers focused on venture and growth stages, so it may do less for very early companies.
How founders can respond
This section is editorial guidance, not investment advice.
- Raise for a milestone. Work out what you need to reach the next clear proof point, such as revenue, a pilot customer or regulatory approval, and raise for that.
- Show traction. In a selective market, investors want evidence. Paying customers, retention data and a credible plan matter more than market size.
- Look at angels and regional funds. The British Business Bank's Regional Angels Programme backs angel groups to reduce regional gaps in early-stage finance.
- Use tax reliefs. Many angel investors look for SEIS and EIS eligibility. Check whether your company qualifies before you start talking to investors.
- Consider non-equity routes. Start Up Loans, grants for specific innovation projects and revenue-based finance can extend your runway without giving up shares.
- Leave more time. Seed rounds are taking longer. Start conversations well before you run low on cash.
