Closing date Competition
29 October 2026 Security Open Call 2026 Cycle 1 - Stage 2

Innovating for Defence

We’re developing a new way to receive and assess innovative ideas for Defence, following the publication of the Defence Investment Plan. This will help us better connect innovative solutions with Defence needs and support our Military Commands. We’ll share more details on how to submit Defence-focused innovations as this work progresses.

In the meantime, if your idea fits one of the focus areas in the current Security Open Call, please review the competition document and consider applying.

Keep an eye on our website and communications channels for updates on future Defence opportunities.

You can view previous Open Call Cycles here.

Themed Competitions

Themed Competitions focus on specific areas of interest to government. They give you the chance to submit proposals that address a defined challenge or priority.

These competitions often run for a limited time, so keep an eye on closing dates.

Open Stage 2 Themed Competitions

Defence Innovation Loans

The Defence Innovation Loans cycles are currently paused while we work on a new, improved service.

The loan programme is a key resource for funding later-stage research and development (R&D) and commercialisation of mature defence innovations. 

If you are a high-growth, active innovation business and would like to learn more about the programme while the cycles are closed, please contact you local Innovation Partner who can provide further detail and introduce you to our Business Growth specialists where appropriate. 

View previous Defence Innovation Loans cycles here.

Market Exploration

Market explorations help us understand what solutions already exist, what’s in development, and where further investment might be needed. We gather information on current market capability in a specific area – this helps us stimulate the market and shape future activity.

Please note that these requests for information do not commit us to launching a formal UKDI competition.

View previous Market Explorations here.

Competitions in our pipeline

We’re always exploring new areas where innovation could make a real difference to defence and security. Below are some of the challenges we’re currently scoping. If one catches your eye, be sure to keep an eye on our website.
