Professional indemnity is easier to understand from examples than from definitions, because the definitions are abstract and the claims are not. Four shapes cover most of what arrives: the wrong recommendation, the specification error, the missed obligation and the delivered defect.
The wrong recommendation
A consultant recommends a system without checking a constraint the brief named. The client buys, implements, and replaces it eighteen months later. Nobody is hurt and nothing is damaged. The claim is the cost of that decision plus the cost of arguing about whether the constraint was really in the brief.
The specification error
A designer specifies a material that fails in the conditions the building actually has. The remedial work, the disruption and the professional fees to put it right are the client's loss, and the argument is about whether the conditions were knowable at the time.
The missed obligation
An accountant files late or misses a relief the client was entitled to, and a penalty or a lost saving follows. Small individually and frequent, and the defence cost is often comparable to the loss itself, which is why the defence half of this cover matters.
The delivered defect
A developer ships software that miscalculates in a way nobody caught, and every customer using it is affected at once. The loss scales with the customer base rather than with the fee, which is the case where an aggregate limit rather than a per claim limit changes the outcome.
Questions people ask about professional indemnity insurance example
What does a typical claim look like?
A financial loss to a client from work that was wrong, plus the cost of arguing about whether it was wrong. Nothing is damaged and nobody is hurt.
Are most claims large?
Frequency sits with small claims such as missed obligations; severity sits with design and recommendation failures. The defence cost is substantial in both.
Why does the aggregate limit matter?
Because one defect in a product can produce claims from many customers at once, which an aggregate limit absorbs only once.
