Customer story: Digital Cost Assurance at National Highways

April 30, 2026 2 min read

How Coria Digital Cost Assurance gave National Highways 99% accuracy in cost forecasting on a multi-billion-pound infrastructure programme.

National Highways manages investment in England’s strategic road network — major schemes that cost from tens of millions to billions of pounds. The traditional approach to commercial assurance can contribute to 12–46% overspend depending on the size and complexity of the scheme, and running that assurance manually costs tens of millions a year.

In partnership with National Highways and one of its key construction suppliers, Coria built Digital Cost Assurance: a hyperautomation tool that takes raw cost data from the contractor’s ERP, applies pre-agreed analytical rules aligned to NEC4, and delivers cost forecasting accurate to within 1%.

  • 99% accuracy in cost forecasting
  • Up to 19% saving versus manual cost assurance
  • Analysis in hours, not weeks
  • Audit-ready by default

Coria’s agility in thought, and focus on delivery, has been immensely helpful in developing Digital Cost Assurance as a critical solution and the business changes required to optimise its use. The results have the potential to change the industry.

Beyond the immediate cost benefits, the change reduces manual error, supports better cashflow for contractors down the supply chain, and creates a transparent, consistent financial dataset major infrastructure owners can defend to their boards.
