Rebuild Costs: Why Market Value Isn't Enough (and What To Do About It)


Underinsurance is a Ticking Time Bomb. Are You Prepared?

In the insurance industry, we often talk about market value. But when it comes to protecting a property, market value is only half the story. The real cost - the cost to rebuild after a total loss - is often significantly higher. And if you're not accounting for that difference, you're setting yourself, and your policyholders, up for a nasty surprise.

Rebuild costs aren't just about bricks and mortar. They encompass everything from current material prices and local labour costs to building regulations and the specific characteristics of the property itself. A historic building, for example, might have a relatively modest market value but require specialist materials and craftsmanship to rebuild, driving up the cost significantly.

The Problem with Generic Estimates

Many insurers rely on broad-brush estimates for rebuild costs, often based on outdated averages or postcode-level data. This approach is simply not accurate enough. It leads to:

  • Underinsurance: Policyholders are left with a significant financial gap if they need to rebuild. This erodes trust and can lead to costly disputes.

  • Overinsurance: Some policyholders are paying too much for coverage they don't need, making your policies less competitive.

  • Inaccurate Risk Modelling: Your entire portfolio is built on a flawed foundation, making it harder to assess and manage risk effectively.
