How to Become an Underwriter in the UK
Underwriters decide whether an insurer should take on a risk, on what terms and at what price. You assess information from brokers and clients, such as property surveys, claims history, financial accounts or medical details, then agree cover, set premiums and exclusions, and stay within your authority limits.
Most underwriters start as underwriting assistants, apprentices or graduate trainees and study Chartered Insurance Institute (CII) qualifications while working. A degree helps for graduate schemes but is not essential.

How to become an underwriter in the UK
There is no single required qualification. Common entry points are underwriting assistant jobs, insurance apprenticeships at Level 3 or Level 4, and graduate schemes at insurers, Lloyd's market firms and managing general agents. You then study CII qualifications, starting with the Certificate in Insurance, moving to the Diploma, then the Advanced Diploma (ACII), which leads to Chartered Insurer status. Underwriters in life and health insurance may train in medical underwriting instead. Many people also move in from claims handling or broking.
- Apply for underwriting assistant, technical assistant or insurance apprenticeship roles, which handle quotes, renewals and documents while you learn how risks are assessed.
- Pass the CII Certificate in Insurance early, as many employers expect it within your first year or so and often pay for it.
- Choose an area such as commercial property, motor, liability, marine, cyber or life and health, as each needs its own technical knowledge.
- Learn to read broker submissions, loss histories and financial statements, and practise explaining why you would accept, rate or decline a risk.
- Work towards the CII Diploma and then the Advanced Diploma (ACII) to qualify for higher underwriting authority and senior roles.
- If you are at university, apply for insurance graduate schemes and summer internships, including those in the London and Lloyd's market.
