Head of Contractual Assurance Delivery - Fixed Term – 9 months (Sizewell C)
Location: London
Salary: c. £110k depending on experience
Bonus: 15% target
Car allowance: £6,900
Benefits: PMI with AXA, 28 days holiday plus bank holidays, contributory pension (up to 7.5% employee / 15% employer)
About Sizewell C
Sizewell C is one of the largest infrastructure projects in the UK, delivering the next gigawatt-scale nuclear power station to support energy security, economic growth and long-term skills development across Suffolk and the wider UK.
Unlike previous nuclear projects, Sizewell C is the first to be funded through a Regulated Asset Base (RAB) model alongside equity and debt. This introduces a unique and evolving regulatory environment, requiring new approaches to assurance, governance and compliance across the full project lifecycle.
The Role
We are seeking an experienced Head of Contractual Assurance Delivery to design, embed and operate robust assurance and compliance practices across Sizewell C’s delivery activities.
This is a build-phase role, ideal for a senior practitioner with strong experience in regulated environments who can translate complex financing, contractual and regulatory requirements into clear, practical operational processes.
Working closely with delivery, commercial and finance teams, you will help ensure that project spend remains aligned to our obligations under the RAB licence, government support package, shareholder agreements and lender requirements.
This role will act as a subject-matter lead for financing assurance, supporting colleagues through guidance, training and constructive challenge. You will help shape how assurance is delivered on the project, establishing new frameworks, ways of working and a small centralised second-line-of-defence capability.
This is initially a 9-month fixed-term contract, with the potential to extend.
Key Responsibilities
Establishing Assurance Frameworks
Conduct gap analysis of the current contractual and governance landscape, identifying areas where processes do not align with financing and regulatory requirements.
Design and implement practical assurance methodologies to track and evidence compliance across:
RAB licence conditions and government support arrangements
Debt and lender agreements
Shareholder obligations
Embed a clear risk-based approach aligned to the Three Lines of Defence model.
Develop and maintain clear documentation, standards and process maps.
Supporting Delivery Teams
Act as a visible and trusted point of contact for financing assurance across the site and delivery community.
Provide training, coaching and guidance to colleagues to build understanding and capability.
Support the development of major alliance structures, including the Civils Works Alliance (CWA) and Mechanical & Electrical Alliance (MEH), ensuring assurance requirements are built into contracting approaches.
Supporting Senior Management
Maintain a near-miss register highlighting where eligible spend may be at risk.
Provide insight, analysis and recommendations to senior leaders on emerging risks and mitigations.
Support the CFO, CEO and wider economic regulatory team in discharging their responsibilities to avoid ineligible spend and demonstrate value for money.
Contribute to discussions with regulators and external stakeholders where required.
Dimensions
Responsibility for recruiting a small, centralised support team.
Ownership of a limited scope budget for short-term specialist consultancy support.
Impact and Relationships
This role is highly dependent on strong relationships with delivery, commercial, finance and programme teams, as well as alliance partners.
The impact of this role is significant: it helps protect Sizewell C from regulatory breaches and ineligible spend, while ensuring transparency and value for money for bill payers and investors.
Skills, Knowledge and Experience
Essential
Strong experience making recommendations and influencing senior stakeholders.
Understanding of the Three Lines of Defence model.
Expertise in RAB funding models
Experience of risk-based assurance approaches.
Ability to translate complex regulatory and financing requirements into operational processes.
Strong regulatory awareness.
Experience in knowledge sharing, training and stakeholder engagement.
Process mapping and design capability.
Demonstrable operational experience.
Contract management experience.
Desirable
Experience within major construction or infrastructure programmes.
Exposure to highly regulated sectors such as energy, utilities or transport.
Understanding of best practice contracting models.
Experience working with government bodies or regulators.
Financial literacy (including IFRS and UK tax awareness).
For this role you must have evidence of right to work in the UK. As a project, we do not discriminate on the grounds of age, gender, race, colour, religion, disability or sexual orientation, and we welcome applications from all sections of the community.
