Health Insurance Runs Its Own No-Claims Discount

Some private medical policies are priced on a scale that moves with the member's own claims. Claiming pushes the price up a step; a clear year moves it back down.

How a claims-linked scale works

The insurer sets a ladder of discount levels against its base rate. Each policy year without a claim moves the member up the ladder, and a claim moves them down.

The movement is usually asymmetric. A single claim can drop a member several steps, while recovery is one step per clear year, so the cost is spread over several renewals.

The scale is applied to a base rate that itself rises with age and medical inflation. A member can hold their discount and still see the premium increase.

Why insurers use it in health cover

Medical claims are frequent and partly discretionary, which makes usage a genuine signal of future cost. Someone who claims this year is more likely to claim next year.

Charging that member more is risk pricing rather than punishment. The alternative is charging everyone the average, which pushes low claimers towards cheaper alternatives.

It also introduces a deliberate friction. A member weighing a small outpatient claim faces a cost, which reduces low-value usage without a formal exclusion.

The small-claim arithmetic

Because the discount is lost for several years, the true cost of a claim is the benefit received minus the additional premium it triggers across those years.

For a modest outpatient invoice, the additional premium can exceed the amount recovered. The claim is valid and payable and still leaves the member worse off.

Insurers generally publish the scale, which makes the calculation possible in advance. It is one of the few insurance decisions that can be worked out on paper.

What counts as a claim on the scale

Definitions vary. Some insurers count any payment made, others only claims above a threshold, and some exclude defined services such as screening or digital consultations.

A claim opened and then withdrawn may or may not register. Where the policy counts authorisations rather than payments, cancelling after authorisation can still affect the scale.

These details decide whether the arithmetic above works, so they are worth confirming before a claim is submitted rather than after the renewal arrives.

Where it differs from motor

Unlike motor cover, a health discount scale is rarely portable between insurers, because it reflects one insurer's own claims record for that member.

Switching therefore often means starting at the base rate, which offsets part of any headline saving. That interacts with the separate question of medical history continuity.

Scale structures, counting rules and portability vary by insurer and jurisdiction and are revised at renewal. The current wording and schedule govern how a claim is priced.
