ACCA Members Professional Indemnity Insurance

For firms in the upper bands ACCA permits aggregate cover where: the aggregate limit is at least double the any-one-claim requirement, or ACCA caps the self-insured excess at 2% of gross fee income per claim, subject to insurer agreement.

Types of Acca Insurance

The ICAEW PII Regulations apply at firm level. Where the practice operates through a holding entity with subsidiary undertakings (common in the consolidator model of recent years), the regulations require that the consolidated gross fee income be used to calculate the limit, and that all entities undertaking regulated work be named insureds. Networks where firms share branding but not legal structure must each carry their own compliant cover. ICAEW minimum: greater of 2.5 × gross fee income or £1.5m, capped at £3m for sub-£12m firms; "adequate" cover beyond. Excess cap: the lower of £30k per principal or 3% of gross fees.

Why choose ACCA?

Must place with a Participating Insurer; run-off mandatory. How Much PI Cover Does My Accountancy Practice Need? The Association of Chartered Certified Accountants regulates UK-based members in practice through the Global Practising Regulations (GPR), with PI requirements set out in Annex 1 and referenced by ACCA's Bye-Law 8 conduct framework. The minima are constructed in a sliding scale rather than a single floor. ACCA's PII requirement scales the minimum limit to gross fee income as follows: A firm sitting just above each band must move up to the next minimum — and underwriters typically price at, or above, that minimum. Where the excess exceeds this, the principals must be able to demonstrate capital sufficient to honour it. ACCA Bye-Law 8 — the foundation of the Disciplinary Regulations — empowers ACCA to discipline members for failing to comply with the GPR, including PII. A practitioner who allows cover to lapse, places with a non-compliant insurer, or fails to notify ACCA of a material claim, is exposed to a disciplinary process.

Continuing professional development records and PII evidence are typically requested together at the annual practising certificate renewal.

Run-off is required for at least six years following cessation of practice, with the limit equal to the last live limit.

• Understand the claims process, including how to contact the insurer's emergency helpline.
• Know what is not covered (exclusions) such as wear and tear, mechanical breakdown, or damage from certain events.
• Check if the policy provides a guaranteed hire car following a non-fault accident.
• Be aware of the insurer's approved repairer network and any implications for using it.

ACCA recommends — though does not mandate — that audit firms maintain run-off for longer where the firm has signed Companies Act audits within the limitation window.

Why should accountants buy cover?

A practitioner who holds membership of more than one body must comply with the highest standard. A firm that has both ICAEW and ACCA principals must meet the ICAEW PII minimum if it is higher than ACCA's, and vice versa. Where an ICAEW-registered firm holds an audit registration, the audit regulations themselves bite on top of the PII regulations. Where a firm contains a licensed insolvency practitioner, that individual's licensing body sets a further minimum. The chartered bodies (ICAEW, ICAS, CAI) and ACCA are Recognised Supervisory Bodies (RSBs) for audit purposes under the Companies Act 2006, with the Financial Reporting Council (FRC) exercising direct oversight over Public Interest Entity (PIE) audits.

Claims Made Policies

The Insolvency Service oversees the RPBs that license insolvency practitioners. HMRC supervises the AML duties of accountancy service providers that are not supervised by their professional body. The interaction matters for PI because the supervisory regime drives the conduct standards a court will use to set the duty of care. Ten significant UK accountancy and tax bodies have a PI rule set. Each has its own minimum limits and run-off requirements.

A firm with multi-body membership must meet the highest applicable standard. Audit, AML and insolvency layer further requirements on top of the baseline PII rules. The Institute of Chartered Accountants in England and Wales sets out its Professional Indemnity Insurance Regulations as a stand-alone rule set, last consolidated by Council and amended periodically. Every ICAEW firm — defined as a firm with at least one principal who is an ICAEW member, or one that uses the description "Chartered Accountants" — must hold cover meeting these regulations. The ICAEW PII Regulations (Regulation 3.3 and supporting schedule) require firms to hold cover of: the greater of two-and-a-half times gross fee income in the immediately preceding accounting year, or subject to an overall cap of £3 million any one claim where 2.5 × gross fee income exceeds £3 million. Worked example: A sole-practitioner ACCA member with gross fee income of £180,000 must hold 2.5 × £180k = £450,000 — above the £100k floor and below the £500k band minimum.

• For young or inexperienced drivers, consider telematics (black box) policies to potentially reduce premiums.
• Build a No Claims Discount (NCD) by driving claim-free; protect the NCD if the policy offers that option.
• Declare any business use accurately, as using a vehicle for business on a social-only policy invalidates cover.
• Ensure all drivers hold a valid license for the vehicle category and have the insurer's permission to drive.
• Provide accurate annual mileage estimates to the insurer, as significant underestimation can affect claims.
• For classic cars, ensure the policy is specifically designed for classic or vintage vehicles with agreed value.

The next band starts at £200,001 of fees, when the limit jumps to £500,000 minimum. ACCA requires its members in practice to: Confirm PII compliance annually at practising certificate renewal; Disclose insurer details to ACCA on request; Notify ACCA of any decline, cancellation, void or non-renewal within 14 days.

ACCA uses a four-band sliding scale, floored at £100k for the smallest practices and capped at £1.5m for the largest under the formula. Excess capped at 2% of gross fee income. Six-year run-off mandatory; Bye-Law 8 disciplinary risk for any breach.

Frequently asked questions

Firms with gross fee income above £30 million negotiate higher limits but are no longer governed by the formulaic minimum and instead must demonstrate cover that is "adequate and appropriate" in writing to ICAEW. Regulator says: ICAEW PII Regulations expressly require the minimum to be calculated on an any one claim basis, not in the aggregate, except for firms operating with aggregate cover (see 3.3 below). The maximum permitted self-insured excess is the lower of: 3% of the firm's gross fee income. A firm with five principals therefore cannot run an excess above £150,000 per claim without seeking a dispensation. Where the firm wishes to retain a higher excess, ICAEW must be notified and a written justification (typically supported by capital adequacy) is required.

16.3 Why the smallest practices pay a "first-policy premium"

Where a firm elects to purchase cover on an aggregate rather than "any one claim" basis (more common in the £20m+ fee income segment), the aggregate limit must be at least equal to the any-one-claim minimum, and at least one reinstatement must be purchased. Reinstatement effectively buys a second tower of the same size to respond to a separate later claim. ICAEW PII obligations do not end with placement. Disclose to clients on request the existence and limit of PII (and to ICAEW on request); Notify ICAEW if cover is cancelled, declined, declared void, or subject to material restrictions; Maintain run-off for at least two years if the firm ceases (ICAEW recommends six years and a longer period is industry standard, particularly where audit work has been undertaken); Use a Participating Insurer — only insurers approved by ICAEW under the participation scheme may write the cover. ICAEW maintains a published list of Participating Insurers.

13.4 The R&D investigation overlap (preview)

The Participating Insurer agreement obliges the insurer to: offer renewal terms unless misrepresentation or non-payment is established; not impose retroactive date restrictions on continuing risks; give a minimum of 30 days' notice of any cancellation; Firms placing with non-participating insurers are in breach unless they have obtained specific dispensation. This matters bet uk gambling sites sports at renewal: a "cheaper" non-participating quote may not be a permitted alternative. Worked example: A four-partner ICAEW firm in Bristol with gross fee income of £1.6 million must hold not less than 2.5 × £1.6m = £4m any one claim, but is capped at the £3m floor where 2.5 × fees > £3m — so the minimum is £3m. Excess cannot exceed the lower of 4 × £30k = £120k, or 3% × £1.6m = £48k. The binding excess cap is therefore £48k. The Institute of Chartered Accountants of Scotland regulates members and firms operating north of the border, but its rule set applies UK-wide to ICAS members in practice.

Claims Made Versus Occurrence-Based PI Policies

An accountant's signature on a set of accounts is relied upon by HMRC, by the lender financing the client's overdraft, by the trade creditor extending payment terms, and — in the case of audited accounts — by the entire market. The duty of care framework set out in Caparo Industries plc v Dickman [1990] 2 AC 605 restricts third-party recovery, but a quarter-century of case law since then has substantially carved out exceptions: assumed responsibility cases, Hedley Byrne economic loss claims, and the modern strand of audit-third-party claims following Barclays Bank plc v Grant Thornton UK LLP [2015] EWHC 320 (Comm). The third structural feature is the time over which a claim can crystallise. An audit signed in year one may not produce a writ until year seven, when a subsequent insolvency exposes the underlying error. A tax planning structure that has worked for a decade can collapse if HMRC's policy position shifts.

15.2 The IP Bond — the statutory bond

Limitation begins to run when the cause of action accrues (six years for contract under the Limitation Act 1980, six years for negligence, twelve from latent damage discovery under s.14A) — and that creates a long-tail liability profile that PI underwriters price for explicitly. Watch out: because of the long tail, run-off cover is not optional for retiring accountants. The Limitation Act gives a claimant up to 15 years from the act complained of to bring proceedings in certain latent damage scenarios. Six years of run-off is the regulatory minimum for most bodies — the prudent figure is longer. Accountants combine statutory roles, third-party reliance and long claim tails — three features that drive a distinct PI underwriting class.

Do accountants need public liability insurance?

The Companies Act 2006, Insolvency Act 1986 and a 30-year body of negligence case law set the duty framework. Run-off cover is mandated by every accountancy body. Six years is the floor; longer is prudent. The Ultimate UK Professional Indemnity Insurance Guide (2026) How Much PI Cover Does My Accountancy Practice Need? Before drilling into individual rulebooks, it is worth orienting on which bodies regulate which work, and which PI rule applies when a firm is a member of more than one. The Public Practice Regulations set out the PII obligations.
