Pinsent Masons advises Arch Re on cross-border insurance business transfer

01 Dec 2025 | 09:10 am |

Multinational law firm Pinsent Masons has advised two subsidiaries of Arch Re – Southern Rock Insurance Company Limited (Southern Rock) and Alwyn Insurance Company Limited (Alwyn) – on the successful completion of an insurance business transfer under Part VII of the Financial Services and Markets Act 2000.

The transfer, which is scheduled to take effect on 31 December 2025, will move Southern Rock's remaining claims and expired policies to Alwyn. Both companies are Gibraltar-incorporated subsidiaries of Arch Re. 

Alongside the UK Part VII process, Southern Rock will also transfer its Gibraltar business to Alwyn under Part 23 of the Financial Services Act 2019 (Gibraltar).

The Pinsent Masons team advising on the Part VII transfer was led by Partner Peter McCusker, with support from Partner Hammad Akhtar and Associate Priyanjoli Bose. ISOLAS LLP advised on the Part 23 Transfer in Gibraltar, with the team led by Partner Christian Caetano.

Pinsent Masons Partner Peter McCusker commented: “This transaction highlights the post-Brexit complexity of transferring UK insurance business between Gibraltar based carriers. Successfully navigating the Part VII and Part 23 regimes required close collaboration with regulators and advisers in both jurisdictions.”
