UK Defence Innovation (UKDI)

UK Defence Innovation (UKDI) powers a smarter defence — accelerating innovation, strengthening security, and growing UK defence technology. We bring defence innovation together to move ideas rapidly from concept to frontline and stay ahead through continual technological advantage. By backing the high-growth, high-tech UK defence firms of the future and supporting start-ups and scale-ups, UKDI boosts national security while making defence an engine for growth.

To accelerate the delivery of cutting-edge innovative capabilities so that the United Kingdom is both secure at home and strong abroad.

Open Call for Innovation

Do you have an idea that could change defence and security – even if no one’s asked for it yet? The Open Call for Innovation is your route in.

We’re looking for disruptive ideas that might otherwise be overlooked. If your innovation could make a difference, we want to hear about it.

We run several competitions throughout the year, giving you regular opportunities to get involved.

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.

Defence Innovation Loans

Defence Innovation Loans help UK-registered small and medium enterprises (SMEs) develop mature innovations into viable business propositions. If you’re an SME with a solution to a defence challenge, you can apply for a loan to take your idea further.
