About Us
Ever-evolving in a world that never stops changing.
MSIG UK combines over a century of insurance expertise with the energy, innovation and agility of a start-up.
We’re proud to be a partner our clients can count on — not just in moments of need, but across generations."
Established in London in 1924 and a wholly owned subsidiary of Mitsui Sumitomo Insurance Company since 1972, we blend deep local market knowledge with the strength of a global network to deliver solutions that protect and empower our clients.
Rooted in our Japanese heritage, we operate on the principles of trust, respect, and care ensuring every partnership is built on transparency and mutual understanding. From our London headquarters in the Leadenhall Building, our specialist underwriters collaborate closely with brokers to design bespoke programmes across commercial property, casualty and marine lines. We are constantly evolving, offering our clients only the highest level of tailored service and products.
At MSIG UK, our commitment goes beyond insurance. We’re also driven to help you and your business succeed. By combining global reach, local insight and a values-driven approach, we stand ready to safeguard your business today, while helping you prepare and adapt for tomorrow.
