Comparing the ICAEW-Marsh route with the open-market specialist route
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.

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.
