IPT audit assurance: Arrangements for visits: Duration of assurance visits
The time you spend on an audit assurance visit fundamentally depends on your judgment about the potential revenue risk and the resources you have to meet it. You should be able to assess (based on your experience and discussion with the insurer) the likely duration of an audit. Try to judge the credibility of the business and address any possible risk areas within the anticipated visit duration. You may have to extend the time as necessary if you need to make fuller enquiries where the revenue may be at risk. If a return visit is required it is generally best to make it as soon as possible after the initial visit.
