Great British Energy (GBE) is a new publicly owned energy company with a clear purpose: to power Britain with clean, secure, home‑grown energy and to help position the UK as a global leader in the clean energy transition.

Our mission is Public Ownership of Energy with Purpose. We exist to accelerate clean energy deployment, strengthen energy security, and ensure that UK workers, communities and taxpayers share directly in the benefits of a cleaner, more resilient energy system. GBE will invest in, develop, build and operate the technologies the UK needs to increase energy independence, while giving communities a direct stake in the transition.

GBE is being built to last - our ambition is to become a lasting national institution the public can be proud of, and a developer, constructor and owner of energy that is Clean, Secure and Yours. From our base in Aberdeen, we are establishing GBE as a cornerstone of the UK's energy landscape. Joining GBE means contributing at the very start of this journey: delivering long‑term public value, helping shape the UK's energy future, and building your career in a mission‑led, values‑driven organisation.

Our ambition is to become a lasting national institution that the British public will be proud of; a developer, constructor and owner of homegrown energy that is Clean, Secure and Yours.

From our base in Aberdeen, we are building GBE not just as a company, but as a cornerstone of the UK's energy landscape: a trusted, transparent and innovative public champion that stands shoulder to shoulder with the leading state‑owned energy companies of Europe. GBE will become recognised both at home and abroad as a world class energy institution that embodies the values, expertise and ambition of the UK.

The Transaction Modelling Officer will support Great British Energy's investment and commercial activity by developing, operating and reviewing financial and transaction models that inform structuring, appraisal, negotiation and decision‑making regarding investment opportunities available to GBE.

The role will work across pipeline, transaction and portfolio activity, helping ensure that modelling outputs are robust, transparent and decision-useful.

The postholder will support the assessment of investment opportunities, commercial options and downside scenarios, while helping improve the consistency and quality of modelling across GBE's sector verticals.

The role will suit an individual with strong modelling experience, attention to detail and the ability to translate complex analysis into clear insight for colleagues and decision-makers.

• Build, maintain and update financial and transaction models to support investment appraisal, structuring, negotiations and portfolio analysis.
• Run sensitivities, scenarios and downside cases on transaction models to assess the financial implications of different transaction terms, input assumptions, risk adjustments and diligence outputs.
• Support the preparation of financial analysis for business cases, Investment Committee papers, approval submissions and negotiation materials, including internal valuations of target projects/investees.
• Work with deal teams, structuring colleagues, finance and portfolio teams to gather assumptions, validate inputs and ensure model outputs reflect the latest position and a robust base case for investment.
• Assist in assessing valuation ranges, value for money, returns, funding requirements and risk‑adjusted outcomes across potential opportunities.
• Document model logic, assumptions, key judgments and outputs clearly so that models are transparent, reviewable and auditable.
• Carry out quality assurance, sense‑checking and version control across models and analytical outputs.
• Help translate modelling outputs into clear charts, summaries and decision‑support materials for non‑technical stakeholders.
• Support continuous improvement in modelling standards, templates…
