Most underwriters specialise in one type of insurance. The main types of insurance are:
- reinsurance: part of the risk is placed with another insurer.
- life insurance/assurance: covers illness, injury, death;
- general insurance: covers household, pet, motor, travel;
- commercial insurance: covers companies;
Insurance underwriters work closely with actuaries, risk and claims managers to ensure a balance between attracting and retaining customers through competitive insurance premiums (fees) and being able to cover any potential losses from claims.
