• Manage the reporting calendar, ensuring key performance information is delivered accurately and on time.
• Partner with stakeholders across the business to understand challenges, provide constructive challenge and influence decision-making through data-led recommendations.
• Champion data quality and integrity by implementing robust controls, assurance activities and governance processes.
• Collaborate with teams across National Grid to improve source data, reporting processes and the overall quality of business insight.
• Drive continuous improvement by helping shape CND's performance framework, ensuring performance measures remain meaningful, valuable and aligned to business objectives.

What you'll need

• Proven experience analysing and interpreting complex data to identify trends, root causes and opportunities for improvement.
• Ability to translate data into clear, actionable insights and recommendations that support business decision-making.
• Strong stakeholder management skills, with the confidence to build relationships, provide constructive challenge and influence outcomes at all levels of the organisation.
• Excellent communication and presentation skills, with the ability to tailor messages and reporting for audiences ranging from operational teams to senior leaders and executives.
• Experience producing performance reports and dashboards using Power BI or similar business intelligence and reporting tools.
• Strong attention to detail, with the ability to manage multiple priorities, meet tight deadlines and deliver high-quality outputs consistently.
• Excellent knowledge of Microsoft Office, particularly Excel, with experience manipulating, analysing and presenting data effectively.
• An understanding of business performance management and how data, regulatory requirements and organisational change can impact business outcomes, coupled with a proactive mindset for continuous improvement.
