Group health insurance puts your staff on a company plan, paid for by the business. It covers hospital care, and most plans now go well past that: money back on day-to-day medical costs, digital GP appointments by phone or video, a nurse helpline and mental health support.
Irish health insurance runs on open enrolment, lifetime cover and community rating. Every insurer must accept your staff, must keep renewing their cover, and cannot charge more for the same plan because of someone's health or medical history. Policies run for 12 months, which is why the plan is worth reviewing every year rather than renewing by default.
