About Flock

Road accidents kill and injure people, damage vehicles, and cost businesses fortunes. But traditional insurance does nothing to prevent them - it just pays out claims when they happen. At Flock, we’re changing that. Using telematics, AI, and real-time data, we proactively help our fleet customers prevent crashes. We obsessively focus on keeping drivers safe, and we put our money where our mouth is - paying out millions of pounds per year to fleets that get safer over time.

We were acquired by Admiral in May 2026. Now we combine the backing of the UK’s leading motor insurer with startup energy and speed. We’re growing fast with bigger plans than ever, and we’re hugely optimistic that our approach will save many more lives in the decade ahead.

We’re on a mission to make the world quantifiably safer. Join us!

About the role

As a Senior Motor Fleet Underwriter, you’ll manage and grow a large portfolio of fleet business, using data and AI to assess risk and tailor cover to each client. You’ll help us move into new segments, including emerging mobility, as we build one of the UK’s largest fleet MGAs. You’ll report to our Head of Motor Underwriting.

You’ll work closely with brokers, mentor junior underwriters and help shape our products, wording and processes. AI is part of the underwriting process itself: you’ll use it to pull risk data out of submissions and triage cases faster, leaving your time for the judgement calls that need an experienced underwriter.

What you’ll be doing

• Manage and develop a large portfolio of motor fleet business and contribute strongly to team targets.

• Build strong, supportive relationships with brokers.

• Help unlock growth in new market segments, including emerging mobility.

• Collate and analyse portfolio data so our Head of Motor Underwriting can track performance.

• Improve how we gather risk information from clients, so quoting and onboarding run smoothly for clients and brokers.

• Spot where our policy wording and cover can improve, and raise it with our Head of Motor Underwriting.

• Train and develop people in the Underwriting and Operations teams, and spread underwriting knowledge across Flock.

• Use AI to extract and check risk information and speed up quoting, keeping your own judgement on every decision.

What you’ll need

• Extensive experience underwriting motor fleet insurance.

• A track record of building strong broker relationships.

• Confidence working with data to monitor and analyse a portfolio.

• Up-to-date knowledge of the motor fleet market and the curiosity to keep up as it changes.

• Experience training or mentoring others.

• Comfortable using AI in your underwriting work, and curious about where else it can help.

Nice to have: experience with large corporate customers, ACII (qualified or working towards it), or working with product teams to get process and customer journey improvements onto the roadmap.

We work hybrid, typically three days a week in our Central London office (fewer office days can be accommodated for longer commute times), a few minutes from Moorgate and Liverpool Street. This role is expected to be field based rather than office based, so visits to client sites, conferences and broker offices count towards office days.

Making the world quantifiably safer takes more than good data. It takes a team where different perspectives are heard, and that’s a priority here. We insure fleets and drivers from every background, and we know a team built the same way makes sharper decisions and a better product for our customers. So we hire on merit, full stop, and we actively encourage applications from everyone. If you don’t tick every box, apply anyway. Just come as your genuine self: the qualities and experiences only you bring are exactly what we want.
