Senior Underwriter – Existing Business

Competitive Salary

Manchester

Are you an experienced commercial underwriter who enjoys owning decisions, shaping portfolios and being trusted to trade? This is an opportunity to step into a genuinely influential role within one of the UK’s leading insurers, where your judgement, market insight and broker relationships really matter.

We are looking for a Senior Underwriter to play a key role in driving profitable growth across our Existing Business portfolio in Manchester. You will have real autonomy, meaningful authority and the chance to influence how we trade with our broker partners in a highly visible regional market.

A bit about the job

As a Senior Underwriter working within Existing Business, you will take ownership of underwriting performance across a broad portfolio. You will be trusted to make confident decisions on larger, more complex and higher‑risk cases, operating within agreed underwriting authority and appetite.

You will work closely with broker partners, building strong, credible trading relationships and using data and insight to monitor portfolio performance, identify trends and drive sustainable growth.

A key part of the role is supporting the wider underwriting team. You will act as a senior referral point and play an active part in developing capability through coaching, mentoring, audits and technical reviews. You will also support the implementation of changes to underwriting policy, appetite and processes, helping to keep the team commercially sharp and aligned to strategy.

While this role is focused on Existing Business, we recognise senior underwriters often have clear preferences. There is flexibility to consider exposure to New Business or a blended portfolio where appropriate.
