Accountants and auditors face notification triggers that do not always arrive as a solicitor's letter or a formal claim. PI policies typically respond to a claim first made, or to circumstances notified, during the period of insurance. For accountants, those circumstances often surface through regulator or tax-authority correspondence long before any client picks up the phone. Missing the trigger risks a coverage dispute with a later insurer.
Apex arranges PI cover for accountants, auditors and multi-disciplinary practices. This entry sets out the traps that recur.
An HMRC enquiry into a client is not, on its own, a claim against the adviser. But where HMRC's correspondence questions the adviser's conduct — the standard of advice, the reasonableness of a position, the completeness of a disclosure — the matter shifts. A letter that names the firm as adviser, requests the firm's file, or flags a possible penalty for careless or deliberate behaviour is a circumstance the firm should consider notifying.
The trap is that the letter goes to the client. The firm hears about it days or weeks later, or only when the client asks for help. Document the date of awareness carefully.
Where the Financial Reporting Council inspects an audit and identifies issues — a limited scope, a lack of evidence supporting a key judgement, a control weakness — the inspection report is a potential precursor to a future claim. If the audited entity or a third party later relies on those findings to pursue the firm, the earlier report is what they will cite. A findings letter graded as requiring significant improvement sits inside the notification perimeter for most PI wordings.
Institute investigations start with a routine-looking letter. A complaint has been received. Information is requested. No finding has been made, but the letter is a notifiable circumstance in most policies, because it evidences a third party alleging something has gone wrong. The commonest error is to leave the broker uninformed until an adverse finding lands.
Since Rangers, the loan charge and the widening use of the general anti-abuse rule, HMRC has pursued advisers alongside users of contested arrangements. Where a firm advised on a scheme HMRC is now unwinding — contractor loans, employee benefit trusts, film partnership relief, sideways loss claims — the enquiry into any user is a signal. Once a pattern emerges the firm should consider a broader notification rather than waiting for individual claims to crystallise.
See blanket vs specific notification for how the two approaches compare.
An ICAEW-regulated firm that also holds FCA authorisation — typical of accountants with a probate, investment business or consumer credit arm — has two notification regimes to satisfy. The institute expects prompt disclosure of matters affecting fitness or discipline. The FCA expects notification of matters of material significance under SUP 15. The PI insurer expects notification of any circumstance likely to give rise to a claim. The three do not always overlap in timing or content. Map the frameworks in advance rather than reacting on the day.
A mid-tier firm's tax practice advised on a contractor-loan arrangement in 2019, used by around 40 individual clients. In 2026, HMRC opens formal enquiries into 12 of the users. The enquiry letters name the firm as the adviser who introduced the arrangement. None of the 12 users has yet written to the firm to threaten a claim.
Even without a formal claim, this is a circumstance the firm should notify at the next reasonable opportunity. HMRC action against advisers who promoted contested arrangements is foreseeable, the pattern of 12 users on one scheme is unlikely to remain contained, and the firm's file will be requested. A specific notification citing the arrangement, the client group and the HMRC enquiry references gives the current insurer the chance to reserve. See notification of claim vs circumstance for the distinction the wording will draw.
Keep a live circumstances log during the year. At renewal, review it against the wording's notification clause and disclose fairly — see fair presentation for accountant PI renewal. For wider context, the accountants PI insurance UK guide 2026 sets out how limits, retroactive dates and aggregation interact. Firms whose partners also give investment advice may find the IFAs PI insurance UK guide 2026 a useful cross-reference on dual-regulator points.
