Modern slavery transparency statement

We are committed to operating responsibly and with high ethical standards, particularly with regard to human rights issues and will not tolerate human trafficking and other kinds of slavery within our operations. We expect equally high standards from our supply chain.

We have undertaken a detailed review of our business operations in response to the Modern Slavery Act 2015. In April 2017 we released our first statement made on behalf of Costain Group PLC and our subsidiary companies (“Costain”) pursuant to Section 54(1) of the Modern Slavery Act 2015. This statement sets out the steps that Costain has taken during the year ending 31 December 2016 to ensure that slavery and human trafficking is not taking place in any part of our business or that of our supply chain.
