UK Defence Startups Are Being Denied Banking Services Under ESG Rules

UK banks are increasingly refusing basic banking services to defence start-ups, driven by anti‑money‑laundering checks and rigid ESG screening. A prominent example is Eyebrook Technologies: co‑founder Will Morris secured about £700,000 in seed funding and government backing but was refused an account by Barclays after six weeks of exchanges, later obtaining one only after escalating the case to the bank’s UK CEO. Several other established and digital banks have turned down defence and dual‑use firms, treating even clearly defensive technologies as reputational or compliance risks. Entrepreneurs report panic and operational paralysis when capital cannot be accessed because of automated or overcautious compliance decisions.

The pattern has prompted political and industry pushback: Conservative shadow minister Andrew Sharpe has raised the issue in the House of Lords, and service providers such as marketing agencies likewise avoid defence clients, constraining the sector’s ecosystem. Banks publicly reiterate support for defence SMEs but acknowledge they are reassessing policies. Founders warn that continued friction will drive companies abroad - particularly to the U.S., where regulatory and funding conditions appear more favourable - undermining UK ambitions to scale defence innovation. Calls focus on clearer government engagement, targeted risk reduction measures, and reconciling compliance frameworks with national defence industrial strategy.
