It is easier perhaps to say that it doesn't literally mean that
anything and everything is insured, as there are a number of
exclusions. "All Risks" has emerged as a term to embrace a wide
range of different standard "perils" that insurance policies have
traditionally provided cover against. These include perils such as
fire, lightning, earthquake, impact, aircraft, explosion, malicious
damage, escape of water, storm damage, flood etc but additionally
will include accidental loss or damage.
NOTE: The term does still have exclusions which typically are
damage as a result of:
- Wear and tear and depreciation
- Gradual deterioration
- Rust, corrosion or discolouration
- A change in temperature
- Insects, vermin, pets
- Woodworm
- Electrical and mechanical breakdown
This list is not exhaustive as wordings vary from insurer to
insurer, and it is essential to check the policy wording applicable
to your policy.
Insurers also define 'All Risks' differently. It is not uncommon
for theft, subsidence, heave, landslip and sprinkler leakage to be
treated as specific perils in their own right and thus NOT include
them under the heading of "All Risks".
