Join us, be part of more.

We make it, store it, move it, sell it, and mend it. 

We’re looking for a Senior Actuarial Analyst to join our Capital & Financial Risk teams at British Gas.

This is a standout opportunity to step into a broad actuarial role, where you’ll work across capital, risk, regulatory reporting, and model development, not just one narrow discipline.

You’ll play a key role in supporting our Solvency II partial internal model, contributing to capital decision‑making and regulatory insight, while working closely with the Head of Financial Risk & Actuarial on high‑profile activities such as the ORSA and Actuarial Function Report.

Location: We offer a hybrid approach, with home working alongside time in our Windsor or London offices for team collaboration.

What you’ll be doing

Capital Modelling & Reporting

• Support the delivery of regulatory and economic capital results for senior stakeholders
• Run elements of the capital model and produce high‑quality, review‑ready outputs
• Contribute to validation, testing, and internal controls for PRA submissions
• Support wider capital and strategic initiatives

Model Development & Insight

• Enhance and develop components of the Solvency II internal model
• Build forecasting tools and GLMs to generate business insights
• Identify opportunities to use modelling to inform commercial decision‑making
• Drive process improvement across the capital team

Risk Management & Regulatory Oversight

• Support production of key deliverables including the ORSA and Actuarial Function Report
• Contribute to stress and scenario testing and review of technical provisions
• Support oversight activities across underwriting, dividends, and risk appetite
• Work closely with the PRA compliance team, including horizon scanning and regulatory monitoring

Here’s who we’re looking for

• Part‑qualified actuary, making good progress with IFoA exams
• Experience in insurance or a consultancy would be desirable
• Exposure to Solvency II, ideally within capital modelling, reporting, or risk
• Strong analytical skills with the ability to interpret complex datasets
• Experience with GLMs, simulation, or statistical modelling techniques
• Coding capability (Python or R) and experience with data visualisation tools (e.g. Power BI)
• A confident communicator, comfortable taking ownership and working with non‑technical stakeholders
