Cost model
Count recurring, retained and claim-time cost
Underinsurance is not limited to total loss; where the policy uses average, the uninsured proportion can remain with the policyholder on smaller damage.
A home is insured for materially less than its rebuild cost and a kitchen fire damages only part of the building.
Correct the full replacement or rebuild value before relying on partial-loss protection.
Cost foundation
Identify which cost is being transferred and retained
What it means
Underinsurance occurs when the declared sum insured is lower than the value that should have been insured under the policy basis. An average clause can reduce a partial claim in the same proportion, even where the loss itself is below the sum insured. The calculation therefore depends on the full replacement value at the date of loss, not only the damaged items.
South African context
Average clauses appear in South African property and business policies with wording that must be read exactly. Inflation-linked increases may help but do not correct an inaccurate starting value, unrecorded renovation or omitted stock. Some policies include a margin or waiver under conditions, but it should never be assumed from a marketing summary.
Cost controls
Record when each amount can change
Write down the provider's answer and where it appears. This makes later review and complaint handling far clearer.
| Policy check | Why it matters | Action to take |
|---|---|---|
| Valuation method | Use rebuild cost for structures and replacement cost for contents | Keep the written answer with the quotation and final schedule. |
| Professional estimate | Know when a surveyor or quantity professional is appropriate | Keep the written answer with the quotation and final schedule. |
| Automatic indexation | Check whether increases keep pace with actual changes | Keep the written answer with the quotation and final schedule. |
| Renovation notice | Update extensions finishes and solar installations | Keep the written answer with the quotation and final schedule. |
| Claim excess | Apply excess separately from any average calculation | Record the channel, reference number, deadline and escalation route. |
Value comparison
Compare financial outcomes on equal assumptions
Use the same scenario and assumptions for every provider. A heading or marketing label is not enough evidence of cover.
| Comparison factor | What it means here | Evidence to request |
|---|---|---|
| Declared value | Record the sum shown on the schedule | The schedule and wording showing the amount or calculation |
| Value at risk | Estimate full reinstatement or replacement at the relevant time | The schedule and wording showing the amount or calculation |
| Insured proportion | Compare declared value with actual value | The current disclosure document, policy wording and schedule |
| Partial loss | Model how a proportional clause could reduce payment | The current disclosure document, policy wording and schedule |
| Policy safeguard | Check any margin waiver or valuation condition | The current disclosure document, policy wording and schedule |
Numbers in context
Work through a cost scenario without hiding assumptions
A hypothetical household insures contents for R600,000 when the correct replacement value at loss is R800,000. It is therefore insured to 75 percent of value. If an otherwise accepted partial loss is assessed at R120,000, a simple average illustration gives R90,000 before excess and other adjustments. This is an educational formula; the actual clause, valuations and claim calculation control the real outcome.
