Most roles at Aon UK are office-based or hybrid, with teams typically splitting time between their London, UK offices and remote working. The day usually starts with team stand-ups or check-ins, followed by focused project work. Collaboration is a significant part of the role — expect cross-functional meetings, client interactions, and working alongside colleagues from different departments throughout the day. The rhythm varies by team, but most people find a mix of heads-down work and collaborative sessions. Peak periods (month-end, quarter-end, project deadlines) can mean longer hours, but the day-to-day pace is generally manageable.

As a 3,500+-person organisation, Aon UK sits at a size where you can genuinely know people across different departments. Teams tend to be close-knit, and there's a real sense of shared purpose. You'll likely have more visibility with senior leadership than you would at a larger employer, which means your contributions are noticed and your ideas can reach decision-makers more quickly.

The culture at Aon UK shapes how the day feels beyond just the work itself. Colleagues describe the environment as one that values Client Focus and Expertise. Lunch breaks, team socials, and informal catch-ups are part of the rhythm — Aon UK recognises that building relationships across the organisation is as important as the deliverables themselves. Most employees report that the people are one of the best things about working here, and that the team dynamic makes challenging work feel manageable.

Career progression at Aon UK follows a relatively clear path for most roles. Promotions typically depend on demonstrating increased responsibility, deeper expertise, and leadership capability — whether that's leading teams, managing clients, or driving technical innovation. The organisation values both specialist depth and the ability to take on broader management responsibilities, so there are usually multiple progression routes available. Don't assume you need to move into management to advance — many insurance & risk services organisations increasingly recognise and reward technical and specialist career paths.

Aon UK invests in structured learning and development programmes, including access to training courses, conferences, and professional certifications. Many employees report that the L&D budget is generous and genuinely encouraged — not just a line in the benefits package that nobody actually uses. Whether it's technical upskilling, leadership development, or industry certifications, there's real support for continuous learning. While formal mentoring programmes may vary across departments, the culture generally encourages learning from more experienced colleagues. Building relationships with senior team members is one of the most effective ways to accelerate your development — seek out people whose career trajectory you admire and ask them for advice regularly.

For insurance & risk management professionals, Aon UK offers exposure to projects and challenges that build a strong CV whether you stay long-term or move on after a few years. The skills and experience you gain — particularly around Client Focus and Expertise — are transferable across the insurance & risk services sector and beyond. Internal mobility is possible for strong performers, with opportunities to move between teams, departments, or even locations as your career develops. Many senior leaders at Aon UK started in entry-level or early-career positions, which speaks to the genuine career development opportunities available.
