Professional indemnity refers to the legal and financial protection a professional seeks against claims arising from negligent advice, services or omissions causing a client financial loss. In practice, it is most commonly used to describe professional indemnity insurance, which covers liability for breaches of professional duty by solicitors, barristers, accountants, architects, surveyors and other regulated professionals.The term itself is descriptive rather than a defined statutory concept, though its operation is shaped by negligence, contract and regulatory frameworks, as well as specific insurance policy wordings. Across England & Wales, Scotland, Northern Ireland and Ireland, usage is broadly consistent, with similar expectations arising from professional codes of conduct and minimum terms for compulsory insurance in many professions.Key legal features include: cover for civil liability (often excluding fines and penalties), claims-made policy triggers, duty to notify circumstances, and insurer rights such as subrogation. Professional indemnity is central to risk management, client protection and regulatory compliance, and is frequently encountered in engagement letters, limitation of liability clauses, panel appointments, tender processes and transactions involving warranties about insurance arrangements.
