      Pros

      * Meaningful work that directly contributes to the UK’s net-zero transition and energy system planning. * Opportunity to work with highly skilled and knowledgeable colleagues across a range of technical disciplines. * Exposure to strategically important projects with significant national impact. * Good environment for people who are genuinely interested in energy, data science, forecasting, and system analysis. * Senior stakeholders are generally open to new ideas and technical innovation.

      Cons

      Employee experience can vary significantly depending on the team and manager. In some areas there is a culture of excessive criticism rather than constructive feedback. Workloads can become unsustainable, contributing to stress and burnout. Concerns around psychological safety are not always addressed effectively. I observed behaviours that I felt were exclusionary and, at times, inconsistent with the organisation's stated values of inclusion and respect. Career development opportunities can be limited when managers prioritise short-term delivery over employee growth. Escalation routes for workplace concerns could be clearer and inspire greater confidence among employees.
