Claims Leakage: The Silent Margin Killer

Claims leakage is a familiar term in insurance, and a frustrating one, because it rarely has a single cause an insurer can point to and fix. It builds up from a long list of small gaps: a repair estimate that was quietly revised after approval, a duplicate claim that slipped through because two documents looked different enough not to match, a medical report that was altered between the hospital and the insurer without anyone noticing.

None of these gaps require sophisticated fraud. Most of them are simply what happens when a claims process depends on documents that arrive from outside the organisation, with no independent way to confirm they are unchanged since they were issued. A claims handler working through a full queue does not have time to call every garage and every hospital to double-check every document — so the system runs on reasonable trust, and reasonable trust is exactly where leakage lives.

The documents driving a claims decision are almost never created by the insurer. Repair estimates come from garages. Medical reports come from hospitals. Assessor reports come from independent surveyors. Every one of those documents can be altered — deliberately or not — after it leaves the issuer's hands, and by the time it reaches a claims desk there is usually no practical way to tell.

This is why claims leakage is so hard to budget for. It is not one large loss that shows up on a report; it is a pattern of small, mostly invisible gaps spread across thousands of files, each one too minor on its own to investigate, all of them adding up over a year.

Closing that gap does not require rebuilding the claims process. It requires giving every document a way to prove, independently, that it still matches what was originally issued — so the small percentage of documents that have been altered can be caught automatically, instead of relying on a claims handler noticing something felt slightly off. The rest of the process stays exactly as it is; only the blind trust in the document itself goes away.
