Who we are

Carbon Underwriting is a new approach for the market.

We are a specialist, independent, Managing General Underwriter (MGU) writing to a mix of third party capacity and our own Syndicate CBN 4747.

Carbon Underwriting is an MGU and Lloyd’s Syndicate driving transformation in the international coverholder market. We operate as an Underwriting and Data Lead with a laser keen focus on coverholder partnerships.

We are a young, dynamic company and recognise the importance of embracing modern technology to deeply enrich our offering.  Without the baggage of legacy systems and mindsets, we’re building a next generation analytics platform to service the needs of both internal employees and external clients. Underpinning our business is our proprietary technology platform Graphene which presents underwriters and coverholders with superior data that motivates profitable and informed underwriting decisions. 

The MGU acts as an incubator, enhancer and springboard for MGAs to encourage accretive and profitable growth, and does so at a market leading expense base.


At the heart of our business is the expertise and calibre of our people. We recruit high quality professionals and work with them to achieve their potential, ensuring they are supported to perform at their best and achieve their goals and ambitions. We value the diversity of our workforce and our success comes from harnessing diverse skills and creating the right environment for everyone to flourish. We were extremely proud of our strong results in the 2021 Lloyd’s culture survey.


We understand that we have a responsibility not only to offer innovative products and outstanding service excellence to our customers but also to manage our business and act in the way they expect of us.


We are fully committed to carrying out our business in an ethical and responsible way and we value the trust that our business partners and communities place in us. We strive to be a good citizen and advocate for change from environmental impacts to the positive contribution we make to the communities in which we do business through our staff volunteering and charity partnerships.

A shared purpose

“At the very heart of our business is building and maintaining strong relationships, and one of our core fundamentals is partnership. At Carbon we partner with like-minded businesses and individuals. Through the combination of our underwriting talent, our access to high quality clients, advanced data analytics informing decision making, we have created a profitable and sustainable business.”
