Head of Financial Control

Sizewell C’s business is to design, finance, construct, commission, operate, maintain, and eventually decommission the nuclear power plant and related infrastructure at Sizewell C in Suffolk. Overall, whilst the Company is in the construction phase, the Boards’ principal focus is on the development and construction of Sizewell C on time, on budget and to the highest quality and safety standards. The Company is maturing to meet all these requirements. Sizewell C is economically regulated by OFGEM under the RAB model similar to other UK electricity distribution networks and Thames Tideway. Sizewell C construction strategy is to replicate the design of Hinkley Point C, using the majority of the same supply chain, but innovating in the way it is delivered to achieve savings in time and cost of around 20%. The CCO will need to be guided by and incorporate lessons learned from the Hinkley Point C commercial delivery to achieve Sizewell C’s ambition. Following Financial Completion and Revenue Commencement, Sizewell C is fully funded and is owned by; The Secretary of State for Energy Security and Net Zero representing HM Government, La Caisse, Centrica, EDF and Amber Infrastructure.

Your Impact

Reporting to the CFO, the Head of Financial Control is responsible for leading the financial control function, ensuring the delivery of accurate, timely, and compliant financial reporting, robust financial processes, and a strong internal control environment. The role provides leadership across financial reporting, finance operations, and internal controls to ensure a single, reliable source of financial truth, supporting effective decision-making by senior management, shareholders, auditors, and other stakeholders. The post holder will play a key role in embedding a culture of financial discipline, control, and continuous improvement, ensuring compliance with statutory requirements, accounting standards (IFRS), and governance frameworks.

Principal Accountabilities

As Head of Financial Control, you’ll provide senior leadership across accounting, financial control, and governance during a major construction programme.

This role is a key link between SZC and its shareholders and will act as the subject matter expert on the IFRS accounting implications of major infrastructure construction. You will bring strong technical accounting expertise, ideally from regulated utilities, construction, or complex capital programmes, alongside experience in assurance, financial reporting, and process improvement.

You will oversee financial reporting, audit management, accounts payable and receivable, and broader financial control activities, ensuring suppliers are paid on time and regulated revenues are collected efficiently. The role also leads finance transformation initiatives, strengthening governance, internal controls, and assurance as SZC operates as a standalone organisation.

Reporting lines include senior managers responsible for financial reporting, financial operations, finance projects, and digital systems. You will work closely with the CFO and Executive Team, providing clear, confident advice on key accounting judgements, risks, and strategic decisions.

This is a senior, high‑profile role requiring strong leadership, stakeholder management skills, and the ability to operate with minimal supervision in a fast‑moving, complex environment.
