Flagship case · £105m portfolio scope
Programme leadership · 2022–Present
Matthew leads quality and assurance governance across Hinkley Point C and Sizewell C security programmes. His work supports technical compliance, delivery decisions, client confidence and programme risk management.
Flagship case structure
The £105m figure describes the combined programme scope. The sections below separate this scale from Matthew's personal leadership and decision accountability.
The combined portfolio covers £45m of Hinkley Point C work and £60m of Sizewell C work. Delivery sits within regulated nuclear-security programmes where technical compliance, supplier performance, client requirements and programme risk need clear control.
Matthew leads quality and assurance governance across the portfolio and provides Acting Senior Project Manager cover. His accountability includes senior delivery decisions, risk escalation, supplier intervention, client engagement and the evidence needed to support acceptance.
Matthew keeps requirements and assurance actions visible, brings technical and delivery risks into governance early, coordinates supplier and manufacturing interventions, and aligns project teams around evidence, ownership and closure.
Ageing assurance actions reduced by 20%. The work also strengthened visibility of open issues, escalation routes and the evidence used in programme decisions.
Stronger control supports schedule confidence, client confidence, supplier performance and controlled acceptance. Teams have a clearer basis for deciding when work is ready to progress and where intervention is needed.
£105m is the combined portfolio scope, not a claim of personal budget ownership. Matthew's personal accountability is the leadership, governance, risk, supplier and client-facing work described in this case. Evidence basis: Career record and project evidence.
