Catastrophe modelling helps UK and London market insurers quantify exposure to perils such as windstorm, flood, earthquake, and terrorism, underpinning underwriting, pricing, and reinsurance decisions. Exposure management and cat modelling teams curate high‑quality location and coverage data, select and calibrate vendor or internal models, and run scenarios and stress tests, while working with underwriters, actuaries, and capital teams to understand model uncertainty, emerging climate trends, and regulatory requirements around aggregation and risk disclosures.
