Introducing a Clearer View of Underwriting Performance

New regulatory reporting under Solvency UK is allowing a more detailed view of underwriting performance across key general insurance lines.

The introduction of Solvency UK marks a new phase in regulatory reporting for the UK insurance market, providing greater detail in how insurers disclose underwriting results. 

Insurance DataLab has used this new framework to expand its underwriting datasets, introducing separate commercial and personal lines views for motor and property insurance, as well as more granular splits within general liability. 

How our underwriting and solvency data is helping a major global insurer benchmark their performance

Under Solvency II, underwriting results were typically reported at a higher level of aggregation, with limited visibility into how different parts of the book were performing. Solvency UK requires insurers to present a more detailed picture of their portfolios while retaining the consistency required for meaningful comparison. 

For motor and property insurance, separating commercial and personal lines highlights differences in profitability, volatility and claims experience that are often masked in headline figures. Within general liability, greater granularity helps distinguish structural performance trends from short-term movements. 

Commenting on the changes, Insurance DataLab co-founder Matt Scott said “Solvency UK gives the market a chance to look at underwriting performance with far more clarity. By separating commercial and personal lines and introducing greater detail within general liability, we’re helping users understand where performance is really being generated, rather than relying on broad averages.” 

These additional splits are fully integrated into Insurance DataLab’s existing underwriting performance metrics, enabling users to benchmark like-for-like portfolios across peers and over time using regulatory data. 

As insurers begin reporting under Solvency UK, access to more detailed underwriting insight is becoming increasingly valuable. By extending coverage across motor, property and general liability, Insurance DataLab is giving users a clearer view of what is driving performance beneath the surface.
