A chartered accountant in Belfast may be regulated by a body headquartered in London, in Dublin, or in both — and that choice drives the PI obligations far more than the firm’s address does.
The accountancy profession in Northern Ireland is structurally bi-regulatory. Chartered Accountants Ireland (CAI) is the all-island chartered body and its members include the majority of NI-based practising firms; ICAEW also has substantial NI membership and any firm whose principals hold ICAEW practising certificates falls under the ICAEW PII Regulations regardless of the practice’s location. ACCA and other bodies layer onto this picture for specific firms. This guide explains the framework, the differences between the regulators’ PI requirements, the cross-border practice dimension, and what NI accountancy principals should be doing on placement and renewal.
The first question for any NI accountancy practice is: which regulator’s PII regime are we required to comply with? The answer is determined by the practising certificates held by the principals, not by the office address.
A firm whose principals hold CAI practising certificates must comply with the CAI Public Practice Regulations and the PII Regulations made under them. CAI’s regulatory remit extends to both jurisdictions on the island of Ireland, and the PII rules are designed to operate consistently across that footprint. The minimum limit, run-off, and qualifying insurer concepts are set centrally.
A firm whose principals hold ICAEW practising certificates must comply with the ICAEW Professional Indemnity Insurance Regulations. ICAEW’s current PII Regulations require firms in public practice to maintain PII with limits that scale to firm gross fee income, with a minimum of £100,000 and a standard requirement of two-and-a-half times annual fee income subject to a £1.5m minimum for firms with fee income over a defined threshold. Run-off is required for a defined period (currently 24 months under the standard run-off provision). The Regulations require cover to be placed with a Participating Insurer that has signed up to the ICAEW Minimum Approved Wording.
A firm whose principals hold ACCA practising certificates falls under the ACCA Global Practising Regulations, which set their own PI requirements and run-off provisions.
Where a firm has principals holding multiple practising certificates — for instance, a CAI principal and an ICAEW principal in the same practice — the firm must meet all applicable PII regimes. In practice this means the more demanding of the requirements drives the placement.
The geographic dimension matters because NI accountants are uniquely likely to act for clients on both sides of the border. The PI policy needs territorial limits and jurisdiction language consistent with that work pattern.
PI for accountants is written on a claims-made basis with a circumstance-notification extension, in line with the structure used across every UK regulated profession. The trigger is notification of a claim or circumstance during the period of insurance; cover then attaches for that matter regardless of when the underlying work was performed.
The ICAEW Minimum Approved Wording, agreed between ICAEW and its Participating Insurers, is the floor in any ICAEW-regulated placement. It sets standard positions on aggregation, fraud and dishonesty (claims by innocent partners against a dishonest principal are covered up to the policy limit; the dishonest principal is excluded), defence costs, and run-off. Insurers may write better terms than the minimum but cannot write worse for ICAEW-regulated work.
CAI’s PII Regulations set similar minimum standards for CAI-regulated firms, including a minimum limit, the requirement for run-off cover on cessation, and rules on permitted excesses. CAI does not operate a Master Policy regime equivalent to the Law Society of Northern Ireland scheme for solicitors; accountancy PI is an open-market placement on both sides of the border.
Cover responds to civil liability arising from the provision of professional accountancy services — audit, tax advice, statutory accounts, advisory, insolvency, valuation, corporate finance. Each service line attracts its own claims profile. Audit and tax advice generate the highest severity claims. Insolvency work has bespoke considerations around officeholder appointments and is often written on extended wordings. Investment business activities regulated by the FCA need separate FCA PII compliance under MIPRU 3.2.
Insurance Act 2015 applies. The duty of fair presentation under section 3 requires disclosure of all material circumstances at inception and renewal — for accountants, this includes fee income by service line, audit firm status, insolvency appointments, and any circumstances that could give rise to a claim. Section 11 prevents an insurer from relying on a breach of a term to decline a claim if the breach could not have increased the risk of the loss that actually occurred.
Consider a hypothetical eight-partner NI accountancy practice with offices in Belfast and Newry, principals split between CAI and ICAEW registrations, combined fee income £4.2m, audit responsible for around 35% of fee income. The firm receives a claim from a client alleging that its 2021 audit failed to identify a fraud carried out by the client’s financial controller, total loss claimed £1.6m.
Notification is given to the PI insurer in the period of insurance. The firm holds £5m limit, primary, with a £25,000 each-and-every-claim excess. Because principals are dual-regulated, the placement has been engineered to meet both ICAEW MAW and CAI PII Regulations; the wording is the more favourable of the two.
The insurer instructs panel solicitors and audit-specialist counsel. Defence runs for eighteen months. The claim is ultimately settled for £950,000 plus defence costs of £230,000. The firm pays the £25,000 excess. The settlement attracts an aggregation analysis because the fraud spans two reporting periods; under AIG Europe Ltd v Woodman logic the matters are treated as one for limit purposes.
The firm’s renewal proposal the following year discloses the claim, the underlying control failures identified, and the remediation steps. Premium rises materially. The aggregation analysis matters because it preserves a single excess rather than two.
Apex’s view: The most common gap we see in NI accountancy placements is jurisdiction. A firm that genuinely acts for Republic of Ireland clients needs the policy to recognise it, and “worldwide territory” is not enough. The second most common gap is run-off planning around retiring principals — the firm only thinks about it three months before the principal’s exit, and by then the cheaper options have closed. Both are fixable with twelve months of lead time and impossible to fix in the last week.
