What actually drives the cost of group health cover

What group medical cover actually is

A group mediclaim policy (GMC) is a single contract between the employer and an insurer covering a defined set of lives. Its useful features compared with retail cover are significant: pre-existing conditions are usually covered from day one, there are typically no waiting periods, and there is no individual medical underwriting. That is why it is genuinely valuable to employees and why it is often the only health cover a young employee has.

The trade-off is that the employer, not the employee, is the policyholder. Terms can change at renewal, cover can be reduced, and it ends when employment ends.

The four things that set the premium

1. Age profile of covered lives. The dominant factor. A workforce with an average age of thirty-one prices very differently from one averaging forty-eight, at identical headcount. Insurers band the lives and price each band.
2. Family definition. Employee only; employee plus spouse and children (1+3); or that plus dependent parents (1+5). Adding parents is the single largest jump in most quotes, because parental claims dominate group health experience. Many employers offer parental cover on a voluntary, employee-funded basis for exactly this reason.
3. Sum insured and structure. A flat sum insured for everyone, or graded by grade or salary band. Grading is common and reduces cost, but creates the awkward position of junior staff having the least cover.
4. Claims experience. Your incurred claims ratio — claims paid as a percentage of premium collected — in the expiring year. This is what drives the renewal conversation more than anything else.

Why a bad claims year costs you for two years

If your incurred claims ratio runs well above the insurer's threshold, the renewal quote will carry a loading. There is no way around this other than changing the policy terms, changing insurer, or absorbing it.

Changing insurer is not the automatic answer it appears to be. The new insurer will ask for your claims data, and a poor ratio follows you. What genuinely helps is being able to explain it — a single catastrophic claim in a small group reads differently from a broad pattern of high utilisation, and the distinction is worth making explicitly at renewal.

The levers, and who pays for them

Every mechanism that reduces the premium moves cost onto the employee at the moment they claim. That is not an argument against using them; it is an argument for being deliberate about which you use.

• Room rent capping. Reduces premium meaningfully. Also triggers proportionate deduction on the whole bill if the employee takes a higher category room, which is the most common source of grievance.
• Co-pay. Often applied only to parental claims, where it is a reasonable way to keep parents in the scheme at all.
• Sub-limits on specific procedures. Predictable and easy to communicate, provided you actually communicate them.
• Graded sum insured. Reduces aggregate exposure without affecting everyone equally.

Whichever you choose, the failure mode is the same: employees who do not know the terms until they are at a discharge desk. A one-page summary of what is and is not covered, circulated at enrolment, prevents most of it.

What group cover does not do

Two gaps worth naming. First, GMC covers hospitalisation — it is not disability cover and it is not life cover. Those are separate products: group personal accident and group term life sit alongside it, and workmen compensation addresses a statutory liability that none of the others touch.

Second, it ends with employment. An employee who has relied on group cover for a decade and leaves at fifty-two faces retail underwriting at fifty-two, with fresh waiting periods. Telling people this while they are still employed — and early enough for them to hold personal cover alongside — is the most useful thing an employer can do with the policy beyond buying it.
