Your PI insurer is disputing coverage — the response playbook
Reviewed by Matthew Bartlett, Director, Apex Insurance Brokers Limited · Published 14 July 2026
Coverage disputes are rare but serious when they happen. Your PI insurer denies or restricts coverage on a specific claim, leaving your firm exposed while the underlying claim proceeds. This page maps the response playbook.
Common grounds for coverage denial
- Late notification. Insurer alleges the firm didn't notify the circumstance in time.
- Non-disclosure. Fair-presentation duty allegedly breached at inception or renewal.
- Excluded activity. Insurer says the work was outside the policy scope.
- Fraud or wilful misconduct. Where the insurer alleges the act was intentional.
- Aggregation issue. Insurer treats multiple claims as one; aggregate exhausted.
- Retroactive date issue. Work done before retro-date; not covered.
Immediate steps
- Request formal denial in writing with specific grounds.
- Engage broker urgently — broker advocates with insurer.
- Consider legal advice, particularly if insurer's position is contentious.
- Document all communications with insurer.
- Continue defending the underlying claim while the coverage dispute is addressed.
- Notify any additional insurers or excess-layer insurers who may also be affected.
The broker's advocacy role
- Communicating with insurer at senior level.
- Escalating within the insurer's organisation.
- Framing the coverage position in the firm's favour.
- Where the wording supports the firm, arguing the point with insurer legal team.
- Where the wording is ambiguous, seeking constructive resolution.
Legal options
- Coverage counsel. Instruct specialist coverage lawyers.
- Mediation. Coverage disputes sometimes resolve through structured mediation.
- Coverage litigation. Where dispute cannot be resolved, litigation may be necessary.
- Financial Ombudsman. For consumer-adjacent scenarios only.
- PRA / FCA engagement. Where the insurer's conduct raises regulatory concerns.
Protecting the firm during dispute
- Continue defending the underlying claim — delay only worsens exposure.
- Preserve evidence supporting the coverage position.
- Fund immediate defence costs personally if necessary, pending resolution.
- Reserve rights against the insurer.
- Coordinate with any other affected insurers.
Preventing coverage disputes
- Prompt notification of all circumstances.
- Full fair-presentation disclosure at inception and renewal.
- Regular wording review for gaps and ambiguities.
- Documented compliance with policy conditions.
- Broker's ongoing management of insurer relationship.
Frequently asked
What are the most common reasons a PI insurer denies coverage?
Late notification is the single most common ground. Non-disclosure of material facts at inception or renewal is next. Specific exclusions and aggregation disputes also occur.
Can I sue my PI insurer if they deny coverage?
Yes. Coverage litigation is available where the dispute cannot be resolved through negotiation. Specialist coverage counsel handles these disputes.
What is the FCA's role in coverage disputes?
The FCA supervises insurer conduct. Where an insurer's behaviour breaches conduct standards, FCA engagement may follow. Not a substitute for the coverage dispute itself.
What is 'reserving rights'?
The insurer takes a position on coverage while reserving the right to change position later. Common in complex claims where the coverage picture is still developing. Firms should reserve their rights in response.
Can the broker force the insurer to pay?
No, but the broker's advocacy at senior insurer levels often resolves disputes short of legal action. Broker's leverage varies with insurer relationship strength.
What happens to my defence during the coverage dispute?
Continue defending. Delay in defence typically worsens the firm's position. Fund defence personally if necessary; recover from insurer once coverage confirmed.
Does coverage-dispute experience affect future PI cover?
Yes potentially. Firms with contested claims histories attract underwriter attention. Documenting the outcome and remediation supports future placements.
What if my insurer becomes insolvent during a coverage dispute?
FSCS or successor arrangements typically respond. The coverage dispute continues under the insolvency framework. Complex situation requiring specialist advice.
