This is a significant leadership role within one of the UK’s most nationally significant infrastructure programmes.

As Lead Estimator, you will be responsible for delivering a comprehensive estimating and cost modelling service for the GDF Programme and for other NWS nuclear projects. You will define, own and continuously improve cost estimating and modelling processes and procedures, ensuring consistent, high‑quality outputs. The role holds accountability for the GDF whole‑life cost model, maintaining and updating cost estimates that inform investment decisions and support engagement with a wide range of stakeholders, including regulatory bodies.

You’ll shape NWS estimating approach, build modelling capability, and ensure estimates are accurate, validated, and aligned to strategic goals. Your expertise will underpin business cases, risk assessments, and whole‑lifecycle planning. This is a key leadership role with real influence on national‑level programmes.

• Integrate cost estimating activities with planning, risk management, and change control to produce realistic, risk-based estimates (e.g., P50 and P80 confidence levels), evaluating cost impacts of changes in scope, schedule, or risk.
• Lead verification, validation, and assurance of estimates, ensuring robust challenge and positive outcomes from internal, external, and regulatory reviews, and supporting independent assurance processes.
• Collaborate with Programme and Project Managers, Procurement, supply chain, and multidisciplinary teams to evaluate contractor bids, challenge costs, ensure value for money, and deliver high-quality commercial decisions.
