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.

Launch Your Career in Broking

Aon is looking for penultimate-year students to join our Commercial Risk & Reinsurance Summer Internship Programme. You do not need to be an insurance expert on day one. Through our internship, you will learn how brokers help clients understand risk, navigate insurance and reinsurance markets, and make better decisions that support resilience and growth. You will build the skills, confidence and market knowledge needed to translate complex risk exposures into structured insurance programmes and serve as a credible intermediary between clients and insurers.

What is Commercial Risk and Reinsurance

Commercial Risk Aon’s Commercial Risk team helps organizations around the world identify, understand, and manage the risks that could impact their people, assets, and performance. We partner with clients across industries to design and deliver innovative risk and insurance solutions - from property and casualty to cyber and specialty risks - using data, analytics, and deep market insight to help them make better decisions and protect their business.

Reinsurance Aon’s Reinsurance team works with insurance companies and other risk-bearing organizations to design reinsurance and capital solutions that strengthen their balance sheets and support profitable growth. By combining analytical expertise, market knowledge, and global reach, we help clients transfer risk, access capital, and respond to emerging challenges such as natural catastrophes, climate risk, and changing regulatory environments.

What You Will Do

You’ll join either our Commercial Risk or Reinsurance team and support colleagues with research, analysis and the preparation of clear, accurate client and market materials. As your knowledge develops, you may help organise and review policy files, submissions and placement records, and contribute to account and renewal activity. You’ll gain insight into the lifecycle of our business, including how risks are assessed, presented to the market and supported through placement and claims activity. During the internship, you will begin developing business communication and data and risk analysis skills, while learning how colleagues approach document review, exposure assessment and market analysis in a commercial environment. We’ll give you meaningful responsibility with appropriate support. Over time, you will learn how colleagues coordinate workflows across teams and use AI-enabled tools alongside human expertise. You will also develop the judgement to translate business, client and risk context into relevant outputs before information is used to support recommendations or decisions.

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:

• 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, there will be an opportunity for you 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.

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.

Aon UK Internship Recruitment: What to Expect

We know applying for your first role can be exciting, and sometimes a little daunting. At Aon, we’re committed to making our recruitment process as transparent and supportive as possible. Here’s how our selection journey works, and what you can expect at each stage:

• Application Review: We process applications on a rolling basis, moving candidates forward as they complete each stage. Every application is carefully reviewed by our team (not by AI). Due to the high volume of interest, this stage can take up to two weeks. Please note: We do not review CVs or cover letters at this point.
• Online Assessment: We understand you want to put your best foot forward, so you’ll have 5 calendar days to complete the online assessment. If you need more time, just let us know as extensions are available.
• Video Interview: Preparation matters, so you’re granted up to 10 days (240 hours) from receiving your invitation to record and submit your video interview. Rest assured: Every video interview is reviewed by a real member of our recruitment team, not an AI system. You’ll typically hear back from us within 2-3 weeks after submitting your interview, though times may vary depending on the number of applications.
• Assessment Centres: Our assessment centres are held in person at the Aon location nearest to the area you applied for. Please note: As a result of receiving many applications, not every candidate who completes a video interview will be encouraged to attend an assessment centre. Assessment centres usually run after Christmas, from mid-January. If selected, we will provide 7-14 days’ notice to assist you in arranging any travel. We run a limited number of Assessment Centres so please make every effort to attend if invited. We reimburse reasonable travel costs (such as standard class train tickets). Flights and hotels are only covered if agreed in advance.
