Head of SI Regulation

About Us

At National Grid, we bring energy to power possibilities.

We are investing around £70bn over five years in our networks in the UK and the US, with a range of ground-breaking projects to expand our networks. We operate across six business units in the UK and the north-east of the US, with group revenue around £18bn.

National Grid Electricity Transmission (NGET) is the electricity transmission owner in England and Wales. It is responsible for operating, maintaining, and investing in the high‑voltage transmission network and for developing the network needed to connect demand and new generation and enable the system transition.

Within NGET, responsibilities are split between two business units – Electricity Transmission (ET) and Strategic Infrastructure (SI). Our SI business is the delivery engine for large, complex transmission infrastructure and delivery of a major programme of connections works, including the development of a number of new and extended substations. It brings together the major project delivery capability and supply chain model to execute the biggest programmes (including Accelerated Strategic Transmission Infrastructure (ASTI).

We are now recruiting for a Head of Regulation in the Strategic Infrastructure business.

Job Purpose

The Head of Regulation – Strategic Infrastructure will be the SI Executive’s trusted advisor on regulation, including attending Executive meetings, and is responsible for the regulatory outcomes for the business unit. You will help the business make confident decisions in a highly visible environment - setting clear regulatory positions, ensuring strong assurance and reporting, and building effective relationships with key stakeholders including Ofgem and Government. You will be responsible for helping the SI Executive to meet their commercial objectives through high-quality regulatory outcomes.

This role will set the direction for regulatory strategy, policy engagement, and assurance for NGET’s Accelerated Strategic Transmission Infrastructure (ASTI) and NGET’s major substation delivery programme. As a member of the NGET Regulation senior leadership team, you will play a key role as the voice of Ofgem in the organisation, playing a constructive critical friend role and helping National Grid to have an effective and influence voice with Ofgem and other important stakeholders. 

The role provides authoritative advice to the Executive and Project Directors on the implications of Ofgem decisions, licence conditions, and regulatory reforms, leading a team of around 30 that offers advice and challenge to improve the design of network investments and produce high-quality regulatory submissions.

Externally, the role leads NGET’s day-to-day senior engagement with Ofgem and is responsible for identifying and resolving regulatory risks and issues and influencing Ofgem’s decision making to secure a fair settlement which creates the right incentives to deliver at pace for the benefits of GB consumers.

Key Accountabilities

• Operationalise the RIIO-T3 deal for the SI business: Translate NGET’s commitments into day-to-day decisions and delivery support, with clear performance grip and “no surprises” engagement with Ofgem. Develop and implement the Regulatory Performance strategy for the SI business unit to ensure effective plans are in place to meet on our commercial objectives. 
• Improve investment decision-making and submissions: Refresh how the Regulation team works with project teams to ensure regulatory requirements are built in from the start (clear gates, better governance, and alignment to Ofgem’s cycles, including six-monthly reopeners). Improve the management of the portfolio of SI regulatory submissions to manage resource pressures and length the planning horizons of the team. 
• Secure regulatory approvals for the major project’s portfolio: Deliver a large portfolio of high-quality, well-evidenced project assessment submissions and establish positive precedents on cross-cutting issues (including ASTI overheads, Great Grid Upgrade costs, and risk/contingency approaches). You will be responsible for securing >£15bn of regulatory allowances in the coming years. 
• Shape the future regulatory framework and policy: getting ahead of the game by identifying improvements in the regulatory framework, including exploring fundamental reforms of the RIIO arrangements. Influencing Ofgem and building support to shape a better price control framework for the future. 
• Support the close out RIIO-T2 and strengthen RIIO-T3 ways of working: Deliver T2 close-out and residual obligations on Ofgem’s timetable, while continually improving the efficiency and quality of T3 reporting and submissions. 
• Build trust and credibility with Ofgem through delivery evidence and building strong and positive senior relationships: Strengthen regulatory narratives and reporting so engagement is underpinned by clear delivery evidence, protecting and improving reputation with Ofgem and stakeholders. You will manage the Ofgem relationship for the SI portfolio. 
• Operationalise the Regulation function (digital/AI-enabled): Create a repeatable operating model with clear business processes, searchable guidance, defined ownership of regulatory risks and consistent ways of working - reducing single points of failure. We are adopting AI tools and agents across the team, and you will need to lead and role-model how we can use the technology to improve how we work. 
• Build a resilient, integrated team: Clarify accountabilities, define regulatory competencies, and strengthen leadership and team health so the function can deliver change and support the wider business effectively. This includes working to embed a new team structure put in place in Spring 2026 and support further integration between the ET and SI parts of the team.
