# Professional Indemnity Insurance
Professional Indemnity (PI) insurance protects architects and their practices against claims arising from negligent acts, errors, or omissions in the provision of professional services. PI insurance is a mandatory requirement for registered architects in most jurisdictions and a contractual requirement on virtually every project. Understanding PI insurance is essential for risk management, contract negotiation, and professional governance.

## Coverage and Exclusions
### Typically Covered
| Risk | Description |
|------|-------------|
| Negligent design | Errors in drawings, specifications, calculations |
| Breach of duty of care | Failure to exercise reasonable skill and care |
| Breach of contract | Failing to meet contractual obligations for professional services |
| Unintentional IP infringement | Inadvertent copyright or design right infringement |
| Libel/slander | Defamation arising from professional activities |
| Loss of documents | Reconstruction costs for lost/damaged project documents |
| Legal defence costs | Solicitor and barrister fees (usually within the indemnity limit) |
### Typical Exclusions
| Exclusion | Reason |
|-----------|--------|
| Deliberate/dishonest acts | Insurance covers negligence, not intentional wrongdoing |
| Work outside scope | Activities not described in the professional services definition |
| Asbestos-related claims | Separate specialist cover required |
| Pollution/contamination | Often excluded or sub-limited |
| Trading debts | Business debts are not professional negligence |
| Fitness for purpose obligations | Design-build warranties exceeding reasonable skill and care |
| Known circumstances | Claims or circumstances known before inception |
| War/terrorism | Standard market exclusion |
---
## Claims-Made Basis
PI insurance operates on a **claims-made** basis (not occurrence basis):
| Concept | Description |
|---------|-------------|
| **Claims-made** | Policy responds to claims first made during the policy period, regardless of when the negligent act occurred |
| **Occurrence-based** | Policy responds based on when the negligent act occurred (rare for PI) |
| **Retroactive date** | Claims arising from acts before this date are excluded |
| **Continuity** | Maintaining unbroken cover is essential; gaps create uninsured periods |
**Critical implication:** An architect must maintain PI insurance continuously, even after completing a project. A claim may not arise until years after project completion (latent defect periods run 6–15 years depending on jurisdiction).

## Run-Off Cover

## Notification and Claims Process
1. **Identify circumstance** — Become aware of potential claim or complaint
2. **Notify insurer immediately** — Even if no formal claim yet (circumstances notification)
3. **Do not admit liability** — Any admission may prejudice insurance cover
4. **Cooperate with insurer** — Provide all requested documentation
5. **Insurer appoints solicitors** — Defence managed by insurer's panel solicitors
6. **Resolution** — Settlement, defence, or withdrawal of claim
7. **Excess payment** — Practice pays excess if claim succeeds or settles
**Critical warning:** Failure to notify circumstances promptly is the most common reason for coverage disputes.
