2023 UK Reinsurers by S&P is based on survey responses from reinsurance organizations in United Kingdom. The premium data relates to a company’s reinsurance premiums written but, in some cases, other metrics will include both primary and reinsurance business. The main group and country listing for each entity surveyed is representative of that group or company’s total reinsurance business written, whether it be life, non-life, or a combination of both.

Ongoing aim in producing this data is to provide market participants with an indication of the ongoing reinsurance capacity available in each market. Hence, we try to exclude intragroup reinsurance, as far as possible. Companies that have not been able to exclude intragroup reinsurance are highlighted in the footnotes.
