Lloyd’s global insurer and reinsurer MS Amlin, and its sister company, Mitsui Sumitomo Insurance Company (Europe) (MSIG UK), have launched a new dual-stamp underwriting capability to expand its London Market presence.
The joint solution allows MS Amlin underwriters to write risks using both its Lloyd’s stamp and MSIG UK’s company paper, offering brokers greater capacity and a single access point to both markets.
The initiative aligns with parent company Mitsui Sumitomo Insurance Company, Limited (MSI)’s strategy to enhance the capacity of its UK subsidiaries.
The dual-stamp offering will initially be available for Natural Resources, Trade Credit & Political Risk, and Accident & Health lines, enabling underwriters to write individual risks across one or both capacity sources.
MS Amlin and MSIG UK will target lead and follow opportunities in the open market, with plans to expand into line slips and binders as operations develop. In addition to providing a single gateway to both Lloyd’s and company markets, the solution will ensure brokers receive a seamless and consistent claims service.
Andrew Carrier, CEO of MS Amlin, said, “We’re committed to driving growth by exploring innovative ways to distribute our products, access new clients, and bring more business into the London market.
“This solution simplifies trading for brokers, providing a single gateway to secure capacity in the Lloyd’s and company markets, broader coverage options, and greater flexibility over risk placement.
“By partnering with MSIG UK, we can leverage our combined reach to unlock new markets and underwriting opportunities, creating greater value for our business and brokers.”
Martyn Rodden, CEO of MSIG UK, added, “There are substantial advantages in harnessing MSI’s global scale, strength and market presence. By working closely with MS Amlin, we can tap into new growth opportunities and expand our market reach.
“This joint solution will give brokers seamless access to two balance sheets and help them to place their client’s risks more efficiently. It also opens up new client groups – such as some banks on the trade credit side – which might not traditionally use Lloyd’s.
“This collaboration demonstrates the creativity and innovation possible when we join forces across group companies. Together with MS Amlin, we remain committed to developing tailored solutions that make it easier for brokers to find the coverage their clients need.”
