HCC International has been named the best insurer in UKGI after our analysis of the Solvency and Financial Condition Reports for insurers across the whole of the UK non-life insurance market.
The insurer earned an Underwriting Rating of 84%, securing an Insurance DataLab Gold Award for the first time and jumping an impressive 15 percentage points from last year’s score of 69%.
Based on our proprietary formula, devised specifically for this research, Insurance DataLab rates insurers across three key pillars – combined operating ratio (COR), three-year aggregate COR, and improvement in the COR over the last 12 months – with the top performers all receiving an Insurance DataLab Gold Award.
HCC International is joined on the list of top performers by Convex (81%), Starr International – the only insurer to have won a Gold Award in each of the last three years (79%), Markel International (77%), Ageas Insurance (75%), and Arch, Ecclesiastical, and Admiral (UK) (all on 72%).
Performance Improves Year-on-Year
Overall performance has improved over the last 12 months, with the average Underwriting Rating rising by three percentage points to 69%, up from 66% last year and 64% in 2023.
This improvement was driven by a six-percentage point improvement in the COR Improvement Rating, which grew to 65% from 59% the previous year as UK insurers marked a welcome return to underwriting profitability – with a market aggregate COR of 96.6% v 102.1% last year.
