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.

Wealth Solutions: Retirement

Right now, UK companies have more invested in pension schemes than the rest of Europe combined. But, has each individual company set aside enough to meet their pensions’ obligations in twenty, thirty or even forty years’ time?

As the market leaders in actuarial consulting, our consultants are here to advise our clients on their defined benefit pension schemes, helping them to handle the associated financial and operational risks, now and in the future. As an Aon Summer Internship, you’ll work alongside the most creative in the industry, earning as you learn and building your career as an Actuary!

Your role as an Actuarial Summer Internship in Wealth Solutions: Retirement

As an Actuarial Summer Intern, no two days in the office are the same. You’ll have the opportunity to work on a range of client teams with colleagues who provide advice and support to either the trustees handling the pension scheme, or the company that provides it.

Our aim is to help you learn about the potential career path ahead of you, while being given real responsibility on client projects. We'll work through classroom-based and on-the-job training to develop your technical and consulting skills — including your understanding of key calculations, communication techniques, project management and networking.

What your day could look like:

Actuarial and Analytical Tasks, such as:

• Regular assessment of the financial position of pension schemes
• Identifying and implementing ways for trustees and companies to reduce the risks in relation to their schemes, including longevity risks, investment risks and inflation risk
• Carrying out calculations relating to the pension scheme for the company's financial accounts; and with respect to individual pension scheme members' benefits
• Estimating pension protection fund levies

Client Focused Tasks, such as:

• Day-to-day management of the pension scheme and internal projects
• Building and managing relationships with clients and other stakeholders of the scheme
• Attending and presenting at client meetings

You’ll be able to work on a range of projects, gaining early exposure to clients to support your development. You’ll can also be involved in one of our specialist teams, focusing in areas such as:

• Risk Settlement, advising clients on the best way to reduce risk through transferring it to a third party.
• Member Options, helping clients reduce risk and/or cost by offering pension scheme members the choice to reshape their benefits to better suit their individual circumstances.
• Analysis of mortality and other demographic factors to predict future trends within Aon's Demographic HorizonsTM team.

Your Development

As an Aon Summer Internship, you will be enrolled onto our Launch Programme when you join. This development programme is built around 3 core elements:

1. Business learning. On the job learning and experiences enabling you to develop your knowledge and understanding of your team and solution line.
2. Centralised learning. UK Summer Internships complete in an Aon Induction, monthly webinars, business skills training and workshops; all designed to develop your knowledge of Aon, build your confidence and your network across our business.
3. Feedback. When you begin your Aon placement, you will have time with your line manager to discuss your goals and over your 12-month programme you will receive feedback and support

Your career beyond your Summer Internship programme

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.
