About the role

Job summary

Across government, the role of data analysis has become central to how organisations understand problems, shape policy and deliver high-quality digital and operational services. As data volumes grow and analytical tools become more sophisticated, there is an increasing need for strong analytical leadership to ensure that data is used effectively, ethically and in ways that drive real organisational impact. Modern data analysis is no longer confined to reporting; it is fundamental to enabling insight-driven decision making, improving services and supporting strategic transformation.

At Ofgem, data plays a critical role in delivering our mission to protect energy consumers and support the transition to a more secure, fair and sustainable energy system. As we continue to develop our digital, data and technology capabilities, the ability to harness data effectively is key to understanding the energy market, informing regulatory decisions and enabling innovation. Within the Digital, Data and Security Services (DDSS) directorate, we are investing in our data capability to embed consistent, high-quality analytical practices across the organisation.

As a Senior Data Analyst, you will lead the delivery of high-impact analytical work, supporting both operational and strategic decision making. You will work across teams and business areas to design, build and deliver data products that provide clear, actionable insights, while ensuring that data is managed, prepared and used in line with best practice and governance standards.

This is a hands-on and influential role, combining strong technical expertise with the ability to engage and influence a wide range of stakeholders. You will play a leading role in advancing Ofgem’s data maturity, promoting self-service analytics and helping to build a more data-driven culture across the organisation.

Job description

You will be responsible for:

  • Leading the design, build, testing and delivery of analytical products, including dashboards, reports, scorecards, visualisations and alerts, using modern data analytics technology such as Power BI, Azure Synapse, Power Query, GIS and Python to answer strategic business questions
  • Ensuring quality of service by managing, cleaning, abstracting, aggregating, transforming, modelling and quality assuring data, and using that knowledge to develop and conduct analytical studies
  • Presenting the results of data analysis and conclusions logically and concisely, in the most appropriate format for a range of customers, enabling informed decision making, upskilling and effective self-service analytics through trusted semantic models, shared understanding and reusable analytical products
  • Interpreting, applying and promoting data governance, data ethics, information security standards, policies and procedures in all analytical work
  • Working closely with users and stakeholders to understand business needs, refine analytical requirements and drive outcome-led development, delivering solutions that provide measurable value
  • Providing technical leadership in data analysis, managing, coaching and guiding junior colleagues while promoting best practice across the team
  • Coordinating and contributing to research, development and continuous improvement activities, including exploration of emerging tools and capabilities such as Copilot Studio and ArcGIS, to strengthen Ofgem’s analytical capability

We are looking for an experienced data analyst with strong technical and analytical skills, and a proven ability to deliver high-quality insight in complex environments. You will have significant experience of applying statistical and analytical techniques to real-world problems, and be confident working with large and complex datasets.

You will bring strong experience of data visualisation, particularly using tools such as Power BI, and the ability to present complex information in a clear, engaging and accessible way. Your communication skills will enable you to work effectively with a wide range of stakeholders, translating business needs into analytical solutions and explaining findings to non-specialist audiences.

You will also have a strong understanding of data governance, data management and information security, ensuring that data is handled appropriately and in line with organisational and regulatory requirements. Experience of working in agile, iterative environments and delivering value early will support your success in this role.

In addition, you will demonstrate a commitment to developing others and contributing to the growth of data capability within your team and across the organisation. Your ability to combine technical expertise with collaboration and leadership will be key to delivering impact.

This is an opportunity to play a key role in shaping how Ofgem uses data to inform decisions and deliver outcomes. Your work will directly support the organisation’s ability to operate more effectively, respond to emerging challenges and deliver better outcomes for consumers at a time when data-driven insight has never been more important.
