Sizewell C

Kier has been appointed as a delivery partner on the Sizewell C Major Civils Framework, supporting one of the UK’s most strategically important low-carbon energy programmes in Suffolk. The framework includes major civils, roads, ancillary works and complex infrastructure packages, with early works including North Plaza and potential future task orders across the Sizewell C programme.

The Sizewell C framework requires disciplined commercial leadership, robust contract administration, strong cost control and a collaborative approach to change, procurement, forecasting and commercial assurance across Kier, Sizewell C and the supply chain.

The Commercial Manager will lead the commercial function for Kier’s Sizewell C framework projects activities, providing visible leadership, contract expertise and commercial governance across project teams, subcontractors and supply chain partners. The role will report day-to-day to the Project Director and functionally to the commercial leadership within Kier’s Nuclear & Energy business.

The role is responsible for coordinating and delivering all commercial management required for the Sizewell C framework projects. This includes NEC contract administration, target cost control, change management, procurement support, subcontract management, commercial reporting, risk and opportunity management, cashflow, applications for payment and final account strategy.
