A reader's question, and a common one: he is 31, his wife is 29, they plan to start a family within the year, and the only health cover in the household is his employer's group policy. Is that enough?

Almost certainly not. Employer group cover is a real benefit and a poor maternity plan, for three structural reasons that have nothing to do with how generous the employer is.

Reason One: Maternity Is Usually Capped or Excluded

Where group policies cover maternity at all, it is typically subject to a sub-limit on normal delivery and caesarean, and those caps are frequently well below what a private metro hospital actually charges. Where they do not cover it, the exclusion sits in the policy wording rather than in the brochure, which is why so many people discover it at the worst possible time.

In retail policies, maternity is an optional or built-in benefit with a waiting period attached. Waiting periods vary widely between products — long enough on many plans that buying after conception is pointless. The only reliable answer for any specific policy is the wording, and the practical rule is simple: the clock starts when you buy, not when you conceive.

Reason Two: You Do Not Own the Policy

A group policy is a contract between the employer and the insurer. You are a covered member, not a party to it. The employer can change the sum insured, the benefits, the insurer or the cost-sharing arrangement at any renewal, and often does as claims experience moves.

That has a specific consequence for maternity planning. A benefit that exists this year is not guaranteed to exist next year, and you have no right to renew it independently. If you are planning around a benefit you do not control, you are planning on borrowed time.

Reason Three: Portability Is Limited

Leave the job and the cover ends, usually on your last working day. Retail health policies are portable by design; group cover is not. For a household planning a birth, a job change in the same year is a realistic scenario — and it is precisely the scenario in which the group policy stops.

There is also the newborn question. Policies generally do not cover a baby automatically from birth; the child has to be added within a defined window, and terms differ on whether any congenital condition is covered. Missing the window is easy to do in the weeks after a birth.

What To Do, In Order

First, buy a separate retail policy now if maternity is on the horizon within a year or two. The waiting period is the binding constraint and it only starts running from purchase. This is the single most common and most expensive mistake in family health planning: waiting until the pregnancy to shop for cover.

Second, read your group policy's maternity clause before deciding how much retail cover you need. If your employer's scheme has a reasonable delivery sub-limit, a retail top-up may be enough. If it excludes maternity entirely, you need a standalone plan that includes it.

Third, when comparing retail plans, compare on four items rather than on premium: the maternity waiting period, the delivery sub-limit for both normal and caesarean, whether pre-natal and post-natal expenses are included, and the window and terms for adding a newborn.

Fourth, check whether the retail policy allows porting and preserves waiting periods already served. Continuity matters if you change jobs mid-plan.

The general principle underneath all of this: treat employer cover as a top layer, not a foundation. It is excellent for what it is — broad, cheap, no medical underwriting — and unreliable for anything that depends on a multi-year timeline you cannot control.
