Insurance, explained

Additional premium

An additional premium is an extra amount charged for insurance beyond the premium already agreed. It can arise when an insurer accepts a change to the insured risk, cover or information used to calculate the price.

01 / The meaning

What it means.

Examples include adding a location, increasing a limit, extending activities or reporting higher exposure under an adjustable policy. The amount may relate only to the remaining period, but it should not be assumed to follow a simple daily calculation. Minimum premiums, different rating factors and the nature of the change can affect the amount. An insurer may also require new conditions alongside the extra charge.

Ask for a breakdown showing the insurer’s premium separately from taxes, broker fees and any financing costs. Paying an invoice without checking the endorsement can leave uncertainty about what changed and when. Obtain confirmation of the effective date, accepted activities and revised terms, especially where a new project or item needs immediate protection. An additional premium does not necessarily remove unrelated exclusions elsewhere in the policy.

02 / Put it in context

A practical example.

Hypothetical example

Hypothetical example: a retailer opens a second shop three months before renewal. The insurer proposes an additional premium and new security conditions. The owner checks both the cost breakdown and the endorsement before assuming stock at the new address is included.

This example illustrates the term. It does not predict a claim outcome.

03 / Read the detail

What to check.

04 / Start a useful conversation

A question for your broker.

What does this additional charge buy, for which period, and what new terms accompany the change?
