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.

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.

Jonny Allen

Partner - Renewables, Power and Energy

London, UK

Jonny is a Partner in our Renewables, Power and Energy team, specialising in offshore renewables.

Jonny has spent the last decade underwriting all forms of renewable energy, most recently as Head of Offshore Renewables at both Travelers Syndicate and GCube. He has led a number of major programmes and complex offshore wind projects from construction to operation. He also held chairmanship of the European Market Group for renewables and sat on the LEG and LMA sub-committees.

If Jonny was not working for McGill and Partners, he would still be underwriting in a hard market.

“I joined McGill and Partners because they offer true differentiation for clients, real value creation, a culture I truly identified with and an opportunity to work with the best talent in the industry; it was a no-brainer.”
