Who we are


Different by design  

We are a specialist insurance and reinsurance broker designed for large clients and complex risks. We focus where it matters most to bring together deep expertise, strong relationships and cutting-edge technology to deliver smarter, faster and exceptional placement outcomes.  

It’s more than about what we do. It’s about how we do it. 

We think differently. Act boldly and change things for the better. Whether it’s crafting placement strategies, building market-leading digital tools or creating a space for new ideas, everything we do is intentional.   

We work with industry-leading clients, top-tier partners and the most talented people in the market.    We’re proud to be a firm where expertise meets innovation and where our colleagues genuinely care about doing exceptional work together.  

A culture of trust 

Our strongest asset is our people. And our culture is built on trust. Everyone one who joins us signs our Contract of Trust, a shared commitment to excellence, accountability and respect. As a result, we have a culture that attracts the best talent in the industry and underpins a culture where brilliant people do exceptional work, together. 

Careers at McGill and Partners

Launched in 2019, our vision quickly attracted the backing of  Warburg Pincus, a leading global private equity firm.  With over 45+ years of investing across the financial services landscape, they are the ideal partner for our ambitious international growth plans.
