How to Start a Defence Tech Startup in the UK: Part 1

UK defence technology startups face a financing and procurement gap between proving a product and winning a production contract. Innovation awards and successful trials are not enough: small, rapidly issued innovation budgets are separate from larger budgets planned years ahead, often by different officials. Founders must therefore identify four stakeholders early - the end user, the senior official who owns the problem, the budget holder, and the commercial officer - and establish a credible follow-on contract alongside any prototype bid. In-person defence events can help build these relationships. For British companies, UK Defence Innovation is now the main entry point, though its programmes are changing; founders should check current guidance, register their company in the UK, and align a specific capability gap with the MOD’s priorities. Other routes include direct engagement with command teams, Commercial X, and support from the Defence Office for Small Business Growth.

Winning interest is only part of the task: compliance and contract terms can still block delivery. Startups should prepare for Cyber Essentials certification and any controls set by the Defence Cyber Protection Partnership, while recognising that personnel clearances generally require sponsorship and may take six to twelve months. Export classifications and licences matter before arranging overseas trials or sales. Intellectual property also needs careful review: under the usual DEFCON 705 terms, firms generally retain newly created IP, whereas DEFCON 703 assigns it to the Crown, potentially compromising core technology and future investment. The practical lesson is to secure a real buyer and procurement path while preparing security, cyber, export, and IP requirements well before a contract arrives.
