Being a responsible business

Our purpose is to improve people’s lives by helping to: connect and keep the nation moving: keep water clean and flowing: power communities sustainably and keep people safe. Being a responsible business underpins everything that we do.

To give us a leading edge, we focus on the issues that matter the most to our people, our clients and our partners. As a result we have made three commitments that we believe will allow Costain to be a leading responsible business.

  1. Ensure Costain is a safe, inclusive and great place to work, where everyone can be at their best
  2. Create a greener future
  3. Enhance the value that Costain contributes to society

Underpinning these commitments are ten actions that our people, partners and suppliers must factor into their decision making; helping us to achieve our long-term ambitions and positively contribute to the UN Sustainable Development Goals.

Responsible business commitments

“We have a clear purpose at Costain to improve people’s lives, both through the services we provide and in the way we operate. We are committed to building a long term sustainable company that creates economic, environmental and social value for our stakeholders.”
