An overlap is the gap's well-dressed twin: here cover isn't missing, it's doubled up. The trouble is, in insurance, protection bought twice typically doesn't mean a double payout – just a double premium. The overlap hunt stops this quiet drain on your money.
- For indemnity insurance (property, liability), the loss is settled once, so parallel cover typically just means paying double premium. For sum insurance (life, accident), however, benefits do accumulate – there, parallel cover isn't automatically wasteful, but a matter of deliberate choice.
- Typical overlaps come from layering over time: inherited policies, cover hidden inside a package, "just to be safe" contracts.
- Weeding it out isn't an instant cancellation: first the map, then the decision, then a proper wind-down at renewal.
Why isn't double cover a good thing?
The logic of compensation is indemnity, not profit: the company can get back its loss, not a multiple of it. If two contracts cover the same risk, the policy wording governs how the payout is split between them – from the company's point of view, the result is typically the same as having one well-sized contract, except it paid two premiums for years in the meantime. Double cover also gives a false sense of security: "surely something covers that" – while in fact both policies might carry the very same exclusion.
The typical overlaps
A few recurring patterns from practice: cover hidden inside a package – a property package contains a small liability module, while a separate liability policy also exists; inherited overlap – when switching insurers, part of the old contract stayed alive; equipment duplication – electronic equipment appears both on a separate policy AND in the general property cover; personal overlap – an executive's individual cover and group cover for the same event; and vehicle over-cover – a fleet package with extras that also exist as separate policies. Every one of these gets caught out on the cover map: wherever one row shows a mark in two columns, there's a question to ask.
The order of weeding it out
Eliminating an overlap isn't a rushed job: first you need to clarify whether the two covers really do the same thing – behind a similar name, limits and exclusions can differ (reading the policy wording). If the overlap is real, the decision is which one stays – typically the one with stronger terms or better value for money. And the wind-down happens in proper order, timed to renewal, so that no uncovered band is created: the order of cancelling and switching. The payoff of the overlap hunt is that rare insurance outcome everyone likes: the same protection, less premium – and that's one reason why, after a review, I sometimes recommend fewer contracts.
