Better Decisions Begin with You

Aon shapes decisions for the better to protect and enrich the lives of people around the world. When you join us, you’ll become empowered to make the same impact, as you explore ways of becoming a more relevant, connected and valued professional. 

Investment Consulting – Client Group

Join Aon as an Investment Consulting summer intern and for 9 weeks step into life as a valued member of our elite team of specialists.

Our consultants have been advising employers and governments on their pension schemes and other wealth, totalling around $4 trillion, for over 60 years.

Your Role on our Investment Consulting Summer Internship

Join us as an investment consulting intern in either our Defined Benefit (DB) Client Group or Defined Contribution (DC) Client Group, helping to advise our clients on everything from setting investment strategies and selection of investment managers to corporate transactions and asset transfers.

• You’ll be a key member of our dedicated teams, playing a vital, hands-on role in giving our global clients the support they need. This involves providing investment servicing and advice covering markets and strategic considerations, such as managing assets (for both the DB and DC Client Groups) and liabilities (for the DB Client Group only). You’ll gain early experience of dealing with a wide range of investments, adapting them around economic conditions and outlooks.
• In the DB Client Group, you’ll also learn how and why pension scheme liabilities change because of economic assumptions – such as inflation, interest rates and the effect that market movements have on invested assets. Whilst in the DC Client Group, you'll learn about the DC pension vehicles, applicable regulatory and legislative rules and main asset classes and investment theory relating specifically to a DC pension scheme.

What your day could look like:

Over the internship you could experience:

• Setting investment strategies and selection of investment managers,
• Supporting our consultants on all aspects of environmental, social and governance; or
•  Working with pension scheme trustees to implement their long-term strategies efficiently and target better outcomes.

Whichever team your join, this is your opportunity to immerse yourself in our fast-paced, inclusive culture and learn from the best.

Your Development

As an Aon Summer Intern, you will be enrolled onto our award-winning development programme. Over 9 weeks, you will take part in a wide range of insightful and interactive training and development activities alongside your role, helping you build confidence, broaden your knowledge and develop the skills needed for a future career in consulting. Here are a couple of key elements of our intern development programme:

• Induction – a great way for you to learn about Aon and our Story, meet and network with your fellow interns and Aon colleagues from across our business including senior leaders; technical and business training to equip you with skills and knowledge to help you in your role
• Aon Business focused project – our interns are given a project to complete during the programme. You and your team of fellow interns will be tasked to research and help to find solutions for a real business challenge. At the end of the internship, you will have the chance to present your findings to a panel of Aon colleagues
• 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.

You do not need to bring every technical skill from day one. With support, feedback and practical experience, you will begin to develop your ability to analyse data, research and improve processes, manage documents and workstreams, contribute to client relationships, and communicate clear, evidence-based insights through reports, presentations and discussions. As your career progresses, you may also build deeper consulting and analytical expertise, including more advanced techniques where relevant to your assignments.

Your career beyond your Summer Internship

Our summer internship programme is designed as a potential first step towards a long-term career with us. Your performance during your internship may lead to an offer for a place on our graduate programme in the same business unit the following year. We encourage you to apply for an internship that aligns with your long-term interests and career ambitions. By choosing a role that matches your aspirations, you’ll be better positioned to take full advantage of our Launch development programme, which offers comprehensive support for your professional qualification, a level 4 Diploma in Insurance from the CII (Chartered Insurance Institute), and ongoing career growth.

You will also be expected to study towards your Investment Management Certificate (IMC)  Professional Qualification. After that, we’ll ask you to choose between taking either the Charted Financial Analyst (CFA) or Institute and Faculty of Actuaries (IFoA) professional qualification.
