How to manage PI cover through a merger
Reviewed by Matthew Bartlett, Director, Apex Insurance Brokers Limited (FCA FRN 724952) · Published 15 July 2026
Merging professional practices trigger complex PI considerations. Cover continuity, retroactive-date preservation, and successor-practice arrangements need coordinated planning.
The core challenges
- Two firms — two PI programmes — potentially different insurers.
- Legal entity change — new firm needs its own PI.
- Historic work — retroactive dates matter for both firms.
- Regulatory implications — successor practice rules.
- Client-contract implications — additional-insured provisions.
- Cover-level implications — combined turnover often exceeds each firm's separate needs.
Planning the transition
- Broker engagement 6-12 months before merger date.
- Assess both firms' current PI programmes.
- Structure the successor entity's PI programme.
- Preserve retroactive dates for both firms' historic work.
- Confirm run-off cover for the closing entity.
- Coordinate with sector regulator.
- Document the transition for future placements.
Retroactive-date preservation
- Each firm's PI retroactive date needs to survive the merger.
- Combined-entity PI can extend both retroactive dates.
- Alternatively, run-off arrangements for the older firm.
- Insurance Act 2015 fair-presentation duty on the successor firm.
- Broker involvement in preserving continuity essential.
Successor practice rules by sector
- SRA (solicitors): specific successor-practice framework — complex rules.
- ARB (architects): entity notification required.
- ICAEW (accountants): registration transfers — new firm needs PI.
- RICS (surveyors): firm registration re-arranged.
- FCA (IFAs): authorisation transfers or new applications needed.
Common mistakes
- Assuming PI transfers automatically — it doesn't.
- Neglecting run-off arrangements for the closing entity.
- Missing retroactive-date continuity in the transition.
- Missing sector-specific successor-practice rules.
- Rushing the timing without adequate broker engagement.
- Cost-focused rather than continuity-focused decisions.
Frequently asked
When should we start PI planning?
6-12 months before the merger date. Longer for complex or cross-border mergers.
Can we use the surviving firm's PI for both?
Usually not directly. Combined entity typically needs its own PI at merger date.
Does SRA successor-practice apply automatically?
The rules apply where the successor firm succeeds to the predecessor's practice. Broker engagement in confirming this matters.
What if we're absorbed into a larger firm?
The absorbed firm may benefit from the larger firm's programme. Retroactive dates need continuity.
Does personal liability change for departing partners?
Yes — run-off cover and successor arrangements affect the partners' personal exposure.
What about our client contracts?
Additional-insured arrangements may transfer or need re-arranging. Client notification protocols matter.
