Key takeaway

A state bank and a northern university investor funded two spinouts without foreign leads.

Imperial College London spinout RFC Power renamed itself Certain Energy on 26 August after a £10 million Series A that included £3.5 million from the British Business Bank ¹. The company commercialises manganese flow batteries, a grid-storage technology that holds energy in liquid electrolyte tanks rather than in cells, which suits long-duration storage more than it suits vehicles.

Northern Gritstone put £4 million into a £7 million round for MicroLub, a University of Leeds spinout, on 17 September ². MicroLub makes protein-and-water food ingredients and has reached industrial-scale manufacturing, which is the stage where a food-Science spinout either finds a buyer among the large manufacturers or runs out of patience.

Neither round is large next to the raises at the top of the life-sciences table, and both closed on British money from a state bank and a northern university investor respectively. Spinouts at this size have historically been the segment where a British round stalls and an American lead arrives to complete it. These two did not need one. The Bank's regional vehicles have been deploying into the same gap, and its South West fund reached a deployment milestone in July .

Deep Analysis

In plain English

Two university spinout companies each closed funding rounds built entirely from British money. Certain Energy, which came out of Imperial College London and used to be called RFC Power, raised £10m, with £3.5m from the government-owned British Business Bank. MicroLub, a University of Leeds spinout, raised £7m, with £4m from Northern Gritstone, a fund set up to back research coming out of Northern universities. Both show a pattern: dedicated British funds built specifically to back university research reaching the market.

Deep Analysis

Root Causes

Both rounds are university spinouts backed by dedicated regional vehicles built for that purpose: Northern Gritstone was set up specifically to commercialise research from Leeds, Manchester and Sheffield, and the British Business Bank's participation in Certain Energy's round reflects a similar mandate to back university-linked deep tech.

Neither round needed to look outside Britain because the institutional plumbing for backing this specific type of company, university spinouts, already exists domestically.

Different Perspectives

Nscale and Open Cosmos

Nscale chose the New York Stock Exchange for its listing on 18 September, putting Britain's largest AI infrastructure bet to American public investors rather than British ones. Open Cosmos took the opposite route four days earlier, raising nine figures from an all-domestic syndicate on five years of profit, evidence that staying is possible when the balance sheet allows it.

Dame Chi Onwurah and the Science, Innovation and Technology Committee

Committee chair Dame Chi Onwurah wrote to government on 7 September asking how Matt Clifford's conflict at ARIA arose and what safeguards protect its governance, and expects a detailed response. Her question has not yet been put to the Sovereign AI Unit, whose own chair sits at a venture capital firm while overseeing state AI equity.

The Entrepreneurs Network

The Entrepreneurs Network's founder survey found 65% say Britain is easy to start a business in but only 14% say it is easy to scale one, with 82% negative on tax and 74% finding investment hard to access. On this reading the constraint is regulation and tax, not the capital-vehicle design the state keeps adjusting.

New Economics Foundation

The New Economics Foundation argues fiscal accounting rules, not political will, cap what Britain's state capital vehicles can do. Matching the KfW and Bpifrance benchmark of 1% of GDP would need the National Wealth Fund to deploy roughly GBP21bn a year by 2028-29, about four times its current capacity.

Competition and Markets Authority

The CMA's 8 September report on public procurement asked whether Britain's roughly GBP400bn state-spending system is built to grow high-potential firms rather than simply widen SME participation. Its Recommendation 5 calls for a dedicated frontier-technology procurement framework, an official acknowledgement that today's design may serve the wrong target.

Highland Europe

Highland Europe, the growth-equity firm behind a €1bn-plus fund, took €65m from the British Business Bank into its Technology Growth Fund VI on 30 July via British Patient Capital. For a Geneva-based growth investor, the Bank's cheque is routine cornerstone capital, unrelated to which Whitehall department currently claims to sponsor UKRI.
