Being a responsible business

Our purpose is to improve people’s lives by deploying technology-based engineering solutions to meet urgent national needs across the UK’s energy, water and transportation infrastructures. Being a responsible business underpins everything that we do.

In 2016, we launched our 2025 sustainability strategy, in which we set ourselves ambitious long-term goals.

Our strategy focuses on four overarching pillars; to ensure Costain is a safe and great place to work, to create a better environment, support our local communities and leaving a positive lasting legacy and providing sustainable solutions for the marketplace.
