Accountants' annual PI renewal — ICAEW, ACCA, and non-body-regulated

Q: How much PI insurance does ICAEW require for a small accountancy firm?

ICAEW PII Regulations requires 2.5 x gross fee income, subject to £100,000 minimum and £5m maximum per claim. The floor for most small firms is the £100k minimum; scaling begins at £40k fee income (100k / 2.5).

Accountancy PI renewal cycles vary by professional body. ICAEW firms follow ICAEW’s PII Regulations: at least £2m, or 2.5x fee income with a £250,000 floor if fees are under £800,000. ACCA has its own Rule 8. AAT-licensed members use the AAT scheme. DPB-regulated activity carries FCA-equivalent PII standards. This page maps the annual cycle across the framework. Apex has been placing professional indemnity for 17 years, and our page on what a specialist PI broker for accountants does sets out the approach.

The four regulatory floors

ICAEW PII Regulations. At least £2m for any one claim and in the aggregate; if gross fee income is under £800,000, 2.5 x gross fee income with a £250,000 minimum (from 1 September 2024).
ACCA Rule 8. Minimum limits per ACCA guidance; broadly similar spirit to ICAEW.
AAT. Members offering public services use the AAT PII scheme with minimum cover levels.
Non-body-regulated firms. No legal PII requirement but civil-negligence liability applies; PII strongly recommended.

DPB-regulated activity

Firms doing FCA-regulated investment business under the Designated Professional Body regime carry parallel PII standards derived from MIPRU 3.

ICAEW DPB firms — PII sized against the DPB-regulated business volume in addition to the general accountancy work.
Similar standards for ACCA DPB, ATT DPB, CIOT DPB.
Consumer Duty applies to DPB-regulated retail-facing activity.
Insurer questions at renewal cover both the accountancy and the DPB-regulated components.

Practice-mix drivers of premium

Audit work. Higher rating; specific audit-firm underwriting.
R&D tax credit advice. Rising rating factor under FCA and HMRC scrutiny.
Corporate finance and tax-scheme advisory. Higher rating for aggressive tax planning; specific sub-limits sometimes applied.
Insolvency practice. Different market entirely — specialised insurers.
General tax and compliance. Lowest rating pressure.
DPB-regulated investment business. Separate underwriting question.

The annual cycle

3-4 months before renewal. Fee-income update, practice-mix review, DPB-regulated business volume.
2-3 months. Presentation drafted. Claims record with remediation. R&D tax credit exposure documented.
6-8 weeks. Market pre-briefing.
4-6 weeks. Quotes returned. Comparison across insurers.
2-3 weeks. Bind decision.
Renewal day. New policy incepts.

What insurers ask at accountants' renewal in 2026

Fee income and 2.5x formula compliance. Verification that the cover limit meets ICAEW / ACCA thresholds.
Audit work. Volume, client types, quality-control records.
R&D tax credit exposure. Volume, HMRC engagement, any adverse findings.
DPB-regulated business. Volume, type, Consumer Duty implementation.
Personnel. Founding and current claims history.
Complaints record. Under DISP where FCA-regulated business applies; under ICAEW/ACCA rules otherwise.

Structure options

Higher excess — standard lever for reducing base premium.
Sub-limits on higher-risk activities — ring-fence R&D tax credit or corporate finance work.
Layered programme — primary at ICAEW minimum plus excess for higher exposure.
Discontinue specific activities — commercial decision.
Separate DPB-regulated cover if scale warrants.

Frequently asked

How much PI insurance does ICAEW require for a small accountancy firm?

ICAEW’s PII Regulations (from 1 September 2024) require 2.5 x gross fee income, with a £250,000 minimum, for firms with fees under £800,000, and £2m for larger firms. The £250,000 floor applies until fee income passes £100,000 (£250,000 / 2.5).

Do all accountancy firms renew PI on the same date?

No. Accountancy PII renewal dates vary by firm authorisation date. Common clusters at January (year-end related) and April/July (financial-year cycles). No sector-wide fixed date.

How does R&D tax credit advice affect PI renewal in 2026?

Materially. HMRC and the FCA have both increased scrutiny of R&D tax credit advice. Insurers ask specifically at renewal about R&D volume, methodology, HMRC engagement and any adverse findings. Some insurers restrict cover for R&D work; specialist broker input often needed.

What is the DPB regime and does it affect my PI?

DPB (Designated Professional Body) is the framework under which certain accountancy bodies (ICAEW, ACCA, ATT, CIOT) supervise their members for FCA-regulated investment business. DPB-regulated firms carry parallel PII standards derived from MIPRU 3 in addition to their body's general PII rules.

Do I need PII if I'm not a member of a professional body?

No legal requirement for accountancy work in the UK if you are not regulated by ICAEW, ACCA or another body. However you face professional negligence liability under the general law, and clients frequently require PII as a contractual condition.

What if my firm's fee income has grown but our cover hasn't?

Under ICAEW’s PII Regulations, the minimum scales with fee income at 2.5x until it reaches £2m at £800,000 of fees. If fee income has grown and cover hasn't, the firm may be out of compliance. Adjust at renewal or mid-term.

Do audit firms have different PI requirements?

Same regulatory floor (2.5x formula for ICAEW-regulated) but rating is materially higher. Audit-specific PII is a specialist market with different insurers and typically layered programmes for larger audit firms.

Is insolvency practice covered by standard accountancy PI?

Usually no. Insolvency practitioners typically need separate specialist PII from insolvency-focused insurers. Discuss with your specialist broker — some hybrid firms need dual cover.

How these figures are produced

This guide is built from Apex's own market data: the premiums insurers have actually quoted and charged on professional indemnity risks we have handled. Each night that data is aggregated into anonymised rate bands by profession, fee income and limit of indemnity. No client information is published — a band only appears where it contains at least five separate records, and unusually high premiums are excluded so a single atypical risk cannot distort the guide.

The range shown spans the typical spread of recent market outcomes for similar risks. Individual quotes can fall outside it in either direction. Figures exclude insurance premium tax at 12%.

This calculator is not a quote and is not an offer of insurance or advice. Your actual premium depends on full underwriting of your business, including your activities, claims record and insurer appetite at the time.
