Overview
Gallagher Re is seeking a dynamic and proactive professional to join the UK & Ireland Actuarial team in London, where brokers, actuaries, account handlers, and catastrophe modellers collaborate to deliver exceptional results. As one of the largest broking teams in the industry, we placed over £800 million of XOL premium at the recent 1.1 renewals alone. By joining us, you'll have the opportunity to work with a large and diverse client base, delivering analytical expertise across both long and short tail lines of business to clients ranging from established blue-chips to innovative start-up MGAs.
Together with our brokers, who bring an extensive knowledge of the market, and together with them, you will engage with reinsurers to share analytics, support their decision-making, and challenge their assumptions.
Reasons to use Rodeo
I’m in my final year doing Economics and I don’t know whether to apply for grad schemes now or do a masters first. What do you think?
Honest answer — it depends on where you want to end up. A lot of top grad schemes (Big 4, civil service, banking) don’t need a masters. Let’s look at the ones you’d be competitive for now, and we can decide if a masters actually adds anything.
Also worth knowing: most autumn 2026 applications are open now. Timing matters more than you think.
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
