Professional indemnity insurance for Auditing helps protect you if a client alleges your advice, reports or recommendations caused them a financial loss.
Why Auditing face PI claims
Professional indemnity claims typically arise when a client relies on your output to make a commercial, contractual or regulatory decision. Alleged losses often include rework costs, professional fees and delay-related expenses.
- Tax treatment errors: Incorrect VAT/PAYE/relief treatment leading to HMRC interest, penalties, or missed reliefs.
- Deadline failures: Missed HMRC or Companies House deadlines causing fines, late fees, or covenant issues.
- Material misstatements: Errors in accounts/forecasts relied on for lending, investment or business decisions.
- Scope/engagement disputes: Clients assuming services outside the engagement letter were included.

PI can respond to negligence allegations that caused financial loss, but not all fines/penalties are insurable and cover depends on policy wording. It commonly covers defence costs and compensation where negligence is proven.
Does PI cover work you completed in previous years as a auditing?
PI is commonly written on a claims-made basis. The policy in force when the claim is made is the one that may respond. Check your retroactive date (or whether you have “full prior acts”) and consider run-off cover if you stop trading.
