Costain Defence


Costain is improving people’s lives by helping our clients to deliver and support national strategic defence and security needs.

The first duty of government is to defend our country and to keep our people safe. In the 2015 Strategic Defence and Security Review, the Government set out plans for stronger defence with more ships, more aircraft, more troops at readiness, better equipment for special forces and enhanced cyber security. In order to deliver these plans, the UK’s resources must be as operationally efficient and effective as possible.

What might this mean?

  • Providing value for money to the taxpayer by delivering on time, within budget and to high quality standards
  • Identifying the right advice on procurement, contracting, stakeholder engagement and buildability
  • Taking a whole life view of capability, providing solutions from programme conception to optimising in service assets
  • Adapting at pace where technology advances faster than procurement
  • Harnessing the best research and development, both military and civil.

How Costain can help?

We leverage 150 years of delivering complex programmes, our leading-edge digital technology teams and P3M expertise to help clients transform performance of equipment, infrastructure projects and delivery teams.
