Costain Defence

Defence and Nuclear energy

Supporting the strategic defence capabilities and energy resilience that protect and power the UK, its people, values, and interests.

Both the defence and nuclear markets are highly complex and sensitive, requiring specialist understanding, experience and expertise. Across defence we support the UK’s most strategic systems and the service personnel that use infrastructure to live, work and train for operations. We combine our civil and defence nuclear experience, ensuring long-term, low carbon, energy security, and sustain the UK deterrent programme. We improve our clients’ performance and capabilities to deliver their programmes in more adaptable, flexible and connected ways.

How Costain can help?

We are one of the largest providers of project and engineering services to the UK nuclear market and have been involved with some of the UK’s largest nuclear construction projects.

Specialist services

Operational optimisation and security

We optimise the performance and security of individual assets or entire networks of assets at any point in the lifecycle. We transform infrastructure intelligence through the development and integration of leading-edge digital technology solutions built on our deep domain knowledge and client insight.

Optimisation of processes, systems and infrastructure can achieve improved outcomes such as increasing efficiency, effectiveness and resilience whilst having minimal impact on operations. Optimisation encourages a proactive response rather than reactive. We harness our cross sector experience in delivering programme, portfolio and project management to deliver agile, mature systems.

Nuclear energy capability

Our highly skilled team get the best results from our clients’ investments by providing advice, engineering, design and management expertise in all aspects of project delivery, from concept, through construction and commissioning, to decommissioning and disposal.

Digital technology development, integration, security and support

From strategic advisory through to digital integration and bespoke software and hardware, our technology capability spans the defence lifecycle. Where we add real value is through the integration of existing systems and processes for better outcomes and decision making. Our in-house digital technology team design, rapidly prototype, manufacture, integrate and support bespoke electronics, high integrity software and systems, as well as help clients navigate from legacy to new secure, open systems.

Behavioural leadership coaching and P3M training

Our strategic advice supports teams and leaders throughout the implementation of sustainable change and improvements to major schemes through applied P3M training and executive behavioural coaching. We are also a leading training provider for the provision of earned value management (EVM) and control account manager (CAM) training to major defence contractors.
