Senior Development Underwriter in Cardiff

We are recruiting on behalf of a well-established national insurance company for a Development Underwriter based in the South West. This is a home‑based, market‑facing role with a clear focus on broker development and new business generation across the South West commercial market.

The business operates a strong regional underwriting model and is in an active period of growth. This hire is central to that – not a like‑for‑like replacement, but a genuine development role for someone with the appetite to build broker relationships and grow a regional book.

You will work with real underwriting authority, a defined product suite covering commercial P&C risks, and full support from an experienced central team. The expectation is that you bring the market knowledge, the broker contacts and the commercial drive – the business provides the platform, the capacity and the backing.

This is a dual‑mandate role: you will be responsible for both developing new broker relationships and managing the existing book in the South West. Day to day that means:

• Building new relationships with commercial insurance brokers across the South West, including both national groups and independent brokers
• Underwriting commercial P&C risks within your delegated authority, covering the SME and mid‑market segment
• Managing existing broker accounts, ensuring strong service levels and retention of the current portfolio
• Identifying and pursuing new business opportunities across the Scottish broker market
• Working collaboratively with the wider regional and national underwriting team
• Representing the business in the market with professionalism and technical credibility

The split of your time will be weighted towards new business development, with the expectation that you are proactive, visible and well‑connected in the South West commercial broking market.

We are looking for a commercially minded underwriter who combines technical ability with genuine broker relationship skills. The right candidate will be someone who is motivated by what they build, not just by what they are given to manage.

• Solid experience in commercial P&C underwriting, ideally within the SME or mid‑market segment
• An established network of broker contacts in the South West – national and / or independent
• Background from a composite insurer, MGA or similar underwriting environment
• Technically capable of underwriting a broad range of commercial P&C risks with confidence and autonomy
• Self‑motivated and comfortable working in a home‑based, field‑facing role
• Strong communication and relationship management skills – you are someone brokers enjoy working with and trust
• A track record of generating new business, not just managing what is already there

This is a well‑supported, genuinely autonomous role with a competitive package and real scope for career development. Here is what is on offer:

• Salary up to £80,000 depending on experience
• Performance bonus scheme
• Comprehensive benefits package
• Home‑based working across the South West with flexibility to manage your own diary
• Real delegated underwriting authority – the autonomy to make decisions and move quickly
• A growing regional operation with genuine career development potential as the business expands
• Strong central support from an experienced technical underwriting and actuarial team
• A business that values underwriters and puts them at the front of its commercial strategy

At IDEX, we strive for an inclusion‑first company culture where everyone is treated fairly and can bring their authentic selves to work. We recognise and acknowledge that diverse representation at every level of our business requires continuous and measurable effort. We are committed to driving conscious inclusion across our business and creating equitable pathways.
