Group Health Schemes Underwrite The Group, Not The Person

An employer medical scheme is priced on the characteristics of a workforce rather than on any one member's health. That single difference reshapes underwriting, pricing and continuity.

Risk is assessed across a population

A group insurer looks at headcount, age profile, occupation mix and location, then estimates the claims a population of that shape will generate over a year.

Individual variation matters less as the group grows, because unusually high and low claimers offset one another. The larger the scheme, the more stable the estimate becomes.

That stability is why groups can be offered terms an individual could not obtain. The insurer is pricing an average rather than a person.

Why underwriting questions largely disappear

Many schemes are written on a basis that accepts members without medical questions, subject to conditions about actively working and joining when first eligible.

The insurer accepts that some members will have existing conditions and prices for it in advance. Asking each employee for a history would cost more than it saved.

Some schemes go further and disregard medical history altogether, covering pre-existing conditions from the start. Others apply a moratorium across the group as a whole.

Joining rules replace individual selection

Because there is no individual assessment, the insurer protects itself through eligibility rules instead. Automatic entry at a fixed point stops people joining only once treatment is needed.

Late entrants and voluntary joiners are often underwritten individually for that reason. The concession applies to the compulsory population, not to those selecting into it.

Actively-at-work conditions serve the same function. They exclude cover for someone already absent through illness at the moment the scheme begins.

The renewal is a claims conversation

Group premiums are commonly reviewed against the scheme's own claims record once it is large enough to be credible. A heavy year feeds directly into the next rate.

Smaller schemes are rated more heavily on the insurer's book as a whole, because their own experience is too volatile to draw conclusions from.

Employers respond by adjusting excesses, benefit levels or hospital lists rather than dropping cover. The design of the scheme is the lever, not the decision to insure.

What the individual member carries

Cover under a group scheme belongs to the employer, and the member's rights end when membership does. Continuity into a personal policy depends on what the insurer offers at that point.

Group terms, joining conditions and continuity options vary by insurer and jurisdiction and are renegotiated at each renewal. The scheme documentation in force governs any claim.

The practical consequence is that a member's medical history sits dormant under a group scheme and becomes relevant again the moment they leave it.
