Our employees
We have a manifesto which sets out the organisation that we want to be. The behaviours we want to see. And the clear purpose that we are all working towards.

Our brand values
We deliver a UK mission, providing strategic capabilities and managing national assets and liabilities.
Our priorities and focus are on three areas:
Safe, secure, sustainable site stewardship
Safety, security and sustainability are at the heart of what we do and who we are. Our purpose recognises the importance of the legacy we leave for future generations.
Progress at pace
We have made some significant steps over recent years, moving from design and build, to installation and operation in our legacy ponds and silos, completing some major projects and starting more.
Lifetime value for money
Our investments in asset care, care and maintenance and decommissioning reduce the lifetime cost of the site or individual facilities.
