Fire & business cover

What fire insurance does not cover: the gaps businesses miss

Every fire policy carries a quiet list of things it will never pay for. The businesses that read it before a loss are the ones not surprised after — and some of those gaps can be closed before they ever bite.

Knowing what a fire policy won't pay for is as important as knowing what it will — it is the boundary of fire insurance for business, and the place claims are most often refused.

The short version

  • Standard exclusions include war, nuclear, willful acts, gradual wear and consequential loss.
  • Electrical and mechanical breakdown is treated narrowly.
  • Some gaps close with an add-on; war and nuclear risk have no remedy.
  • Lost income needs business-interruption cover, not a fire add-on.

The standard exclusions

A fire policy excludes war and nuclear risks, willful acts, gradual wear and deterioration, pollution, and consequential losses such as lost income — and it treats electrical breakdown narrowly.

  • War, warlike events and nuclear risks
  • Willful or deliberate acts by the insured
  • Wear, tear and gradual deterioration
  • Electrical or mechanical breakdown — unless specifically covered
  • Consequential loss / loss of income — unless business interruption is added
  • Pollution or contamination, as defined

Some of these gaps can be closed with add-ons; others can't, which is exactly why reading them before a loss matters.

The exclusions that surprise businesses

Three catch businesses out most often: consequential loss, the narrow treatment of electrical breakdown, and gradual deterioration.

Consequential loss — the income lost while you rebuild — is not covered by a base fire policy. Electrical/mechanical breakdown is handled narrowly, so a short-circuit that damages a machine may fall outside the cover people assume they have. And gradual deterioration is never a fire claim.

Which gaps an add-on closes

Some exclusions have a remedy and some don't.

Excluded perils such as earthquake or terrorism can be bought back as add-ons; spontaneous combustion can be added for at-risk stock; lost income needs a separate business-interruption cover, not a fire add-on. War and nuclear risk have no remedy. And where a policy does pay, an inadequate sum insured can still cut it — see the average clause.

Frequently asked questions

Is a short circuit covered by fire insurance?

Electrical breakdown is treated narrowly — damage to the machine itself from over-running or short-circuiting is often excluded, though a resulting fire that spreads may be covered. Read the wording carefully.

Does fire insurance cover lost income while I rebuild?

No — that is consequential loss, excluded from a base fire policy. It needs separate business-interruption cover.
