Comparing the ICAEW-Marsh route with the open-market specialist route
Reviewed by Matthew Bartlett, Director, Apex Insurance Brokers Limited (FCA FRN 724952) · Published 14 July 2026
ICAEW has appointed Marsh Commercial as its exclusive PI insurance broker for member schemes. Not every ICAEW-regulated firm fits the scheme mandate. Firms with R&D tax credit exposure, prior claims, specialist practice areas or specific fee-income profiles often need alternative placement. This page sets out how the ICAEW-Marsh route compares with the open-market specialist route.
How the ICAEW-Marsh route works
- Appointed exclusive broker. Marsh Commercial holds the appointed-broker relationship with ICAEW for member schemes.
- Volume-based scheme pricing. Scheme-eligible firms typically access member-specific pricing terms.
- Streamlined process for standard placements. Firms with clean history and standard practice mix benefit from scheme efficiency.
- Scheme underwriting mandate. Placements outside the mandate are difficult or impossible through this route.
When the ICAEW-Marsh route typically fits well
- Standard general accountancy practice, clean claims history.
- Modest fee income within scheme rating bands.
- Non-audit, non-R&D, non-corporate-finance practice mix.
- Firms already in the scheme with stable renewal trajectory.
When the open-market route typically fits better
- R&D tax credit specialists. Post-HMRC scrutiny 2022+, R&D advice attracts material insurer attention. Some scheme insurers now restrict or exclude R&D work.
- Prior claims or notifications. Difficult-risk cases benefit from specialist Lloyd's market access.
- Firms with material audit or corporate finance work. Higher-rating activity that scheme mandates may not price competitively.
- DPB-regulated firms doing investment business. Additional PII requirements under DPB rulebook.
- Firms wanting independent advice not filtered through scheme book position.
- Firms where scheme renewal quote comes back materially higher than peer expectation.
- Firms operating across ICAEW plus other bodies (ACCA, ATT, CIOT).
Comparison questions to test the scheme route
- How many insurers can my broker place me with? Single-scheme relationship = single insurer route.
- What happens at renewal if the scheme insurer's appetite for my profile changes? Where scheme is the only route, limited options remain.
- Who handles a claim notification — and at what level? Scheme call-centre vs specialist broker with named contact.
- Can I get a comparison quote from the wider market? Free of charge; tells you where the scheme sits.
- Is my R&D tax credit work fully covered under the scheme wording? Some scheme wordings restrict this.

Frequently asked
Is ICAEW Marsh the only route for ICAEW PI?
No. ICAEW membership doesn't restrict PI broker choice. ICAEW Bye-law 61 requires adequate PII from any authorised insurer; the broker is your choice.
Can I use a different broker even as an ICAEW member?
Yes. ICAEW rules don't require use of the appointed scheme broker. You're free to place with any FCA-authorised broker of your choice.
What if my Marsh quote came back much higher than last year?
Common reason to remarket. Sharp renewal premium change is a signal to test the wider market. Open-market specialist comparison typically costs nothing.
Does the ICAEW scheme cover R&D tax credit work?
Depends on the wording and the specific scheme structure. Post-2022 HMRC scrutiny has caused some insurers to restrict R&D advice. Confirm at renewal.
How does the ICAEW 2.5x formula work?
PII must be at least 2.5x gross fee income, subject to £100k minimum and £5m maximum per claim. This is the ICAEW Bye-law 61 requirement regardless of broker choice.
Can Apex place for firms doing DPB-regulated investment business?
Yes. DPB-regulated firms need PII combining ICAEW Bye-law 61 compliance with DPB rulebook standards. Apex places both scopes.
Does switching to an open-market broker affect my ICAEW membership?
No. Broker choice is not a regulatory or membership matter. You remain ICAEW-regulated regardless of PI broker choice.
Can Apex serve me alongside my ICAEW membership?
Yes. ICAEW membership and PI broker choice are separate. Many ICAEW members use independent brokers for PI while remaining active ICAEW members.
