We strive to be a responsible and sustainable business which creates economic, environmental and social value. Our relationship with our supply chain is fundamental to this vision.
Supply chain management
We believe in engaging early with our supply chain to identify key strategic partners including trades, material suppliers and services. By understanding the opportunities and matching them to capabilities in a region, we can collaborate effectively to deliver the best possible solution for a project.
Supply Chain Academy
We support and develop SMEs to align our supply chain partners with the high standards of training and development employed by Costain.
With nearly 20 different modules, the academy provides skills and training in areas such as: a lean approach to improvement; commercial awareness and creating social value. Since its launch in 2012, the Academy has trained more than 5,000 individuals from SMEs.
Supply chain innovation
More than 90% of our innovation is enabled through our supply chain. We work with our suppliers to support product and service development through the Supply Chain Academy, sharing our BSI Kitemarked systems knowledge and supporting and leading on accelerators, including partnerships with National Highways and HS2.

How to become a supply chain partner
We value a diverse supply chain and seek organisations that mirror our culture, behaviours and standards.
To maintain the right calibre of suppliers within our supply chain, potential suppliers must follow one of two pre-assessment routes:
- Via the Achilles BuildingConfidence accreditation scheme. This is our preferred option. However, we now accept all recognised Common Assessment Standard (CAS) bodies and their associated accreditation schemes (click here to learn more).
- Via the Costain materials, plant or subcontract pre-qualification questionnaire completed through our Supplier Relationship Management system (SRM).
