The UK defence sector is expanding rapidly, bringing with it significant opportunity for manufacturers across the UK. But for many businesses, breaking into defence can feel complex, unclear, and difficult to navigate.

That’s why Make UK Defence, in partnership with Lloyds, has developed A Practical Guide to Working in Defence, a clear and accessible resource designed to support SMEs looking to enter, grow, and succeed within the defence supply chain.

Built in collaboration with 14 organisations across industry and government, this guide brings together insight from across the defence ecosystem, including Make UK Defence, Lloyds, MOD, Hellios, HVM Catapult, MTC, Horizon Works, Canny Comms, and more. The report offers a truly joined up perspective on how to get started and scale in defence.

The guide tackles the real challenges businesses face when entering the sector. From navigating complex procurement processes and accreditations to understanding where to start and how to position your capability.

It also provides practical, actionable guidance on:

  • Where opportunities exist across key defence programmes
  • How to engage with buyers and the wider supply chain
  • Meeting critical requirements such as cyber security, sustainability and social value
  • Building a credible marketing and engagement strategy for defence

Importantly, it highlights the growing role of SMEs in strengthening the UK’s defence capability and the increasing support available to help businesses succeed.

This guide sets out not just how to enter defence, but how to build a sustainable, long-term presence in the sector.

Download the full guide to understand the landscape, unlock opportunities, and take your next step into defence.
