Marine Insurance Act 1909

Where the subject‑matter insured is warranted free from particular average, the assured cannot recover for a loss of part, other than a loss incurred by a general average sacrifice, unless the contract contained in the policy be apportionable; but, if the contract be apportionable, the assured may recover for a total loss of any apportionable part.

Where the subject‑matter insured is warranted free from particular average, either wholly or under a certain percentage, the insurer is nevertheless liable for salvage charges, and for particular charges and other expenses properly incurred pursuant to the provisions of the suing and labouring clause in order to avert a loss insured against.

Unless the policy otherwise provides, where the subject‑matter insured is warranted free from particular average under a specified percentage, a general average loss cannot be added to a particular average loss to make up the specified percentage.

For the purpose of ascertaining whether the specified percentage has been reached, regard shall be had only to the actual loss suffered by the subject‑matter insured. Particular charges and the expenses of and incidental to ascertaining and proving the loss must be excluded.
