Better Decisions Begin with You

At Aon, we shape decisions for the better to protect and enrich the lives of people around the world. As an organisation, we are united through trust as one inclusive, diverse team, and we are passionate about helping our colleagues and clients succeed.

Risk Capital

Join Aon as a Commercial Risk or Reinsurance summer intern and spend 9 weeks discovering why insurance, reinsurance and risk management are the cornerstones of every company's capital structure. We help our clients identify their risks, ensuring they have the best possible cover to mitigate them.

As well as identifying risk for our clients, we also predict and spread risk. This means that, if major catastrophes hit, economies can keep going and people can get on with their lives. As an Aon Summer Intern, you'll play a key role in making this essential work happen.

We’ll help you learn about our business and the broking process, develop your professional skills and build strong relationships with clients and colleagues alike.

Commercial Risk Solutions: Trends in economics, demographics and geopolitics – compounded by the rapid pace of technological change – are creating unprecedented volatility for organisations. We assist clients with their insurance buying decisions, aiming to optimize the balance of risk transfer and retention financing through valuation and analysis. You can learn more about our Risk Transfer offerings here: Broking and Risk Transfer | Aon

Reinsurance Solutions: Unprecedented volatility is creating new risks and opportunities for organisations across the global economy. We provide risk transfer, claims advocacy and capital management solutions to help re/insurers reduce volatility and build more resilient businesses, governments and communities.

Your role as Commercial Risk or Reinsurance Broking Summer Intern

You’ll join either our Commercial Risk Solutions or Reinsurance Solutions team, playing a crucial role in delivering dynamic, bespoke intellectual and financial capacity to our clients all around the world.

Our interns experience the full lifecycle of our business — from trading risk in the market and understanding the importance of claims through to winning new business. You’ll focus on developing client-management skills too and build relationships with a broad spectrum of people — including clients, our own industry specialists and members of the global insurance and reinsurance markets.

We’ll give you real responsibility early on, to ensure you gain a deep understanding of your potential future career path.

Your Development

As an Aon Summer Intern, you will be enrolled onto our award-winning development programme. For 9 weeks you will have the opportunity to take part in a wide range of insightful and interactive training and development activities in addition to your role. Here are the key elements of our 9-week Internship development programme:

Feedback. When you start as an intern at Aon, you will have time with your line manager to discuss your goals and throughout your internship you will receive feedback and support

Your career beyond your Summer Internship

Once you’ve completed the summer internship programme, depending on your performance, you may be offered a role on our graduate programme for the following year.
