Professional Indemnity Insurance

Professional Indemnity Insurance (PII), sometimes called professional liability insurance or errors and omissions (E&O) insurance in the United States, protects individuals and firms that provide advice, expertise, or specialist services against the financial consequences of client claims. Covered losses typically include legal defence costs, settlements, and damages awarded when a client alleges that negligent work, faulty advice, breach of professional duty, misrepresentation, or breach of confidentiality caused them financial harm.

PII is standard — and often mandatory — for regulated professions. In the United Kingdom, for example, solicitors must hold PII meeting the Solicitors Regulation Authority's Minimum Terms and Conditions, and chartered accountants regulated by the ICAEW face similar requirements. Architects registered with the Architects Registration Board, medical practitioners, financial advisers under FCA rules, and management consultants commonly carry PII either by regulation or client contract. In think-tank and research contexts, organisations commissioning policy work frequently require contractors to evidence a minimum level of cover, often £1–5 million per claim.

Key features include:

• Claims-made basis: Most PII policies respond to claims made during the policy period, not when the alleged error occurred. This makes continuous renewal and "run-off" cover after a firm closes important.
• Retroactive date: Defines how far back covered work extends.
• Aggregate vs. per-claim limits: Policies may cap the insurer's total annual payout or set a limit per individual claim.
• Exclusions: Typically include fraud, dishonesty, known prior circumstances, and contractual liabilities assumed beyond ordinary professional duty.

For researchers and consultants working with governments or international organisations, PII intersects with procurement rules: the UN, World Bank, and EU institutions routinely require vendors to carry professional liability cover proportionate to contract value. The insurance also functions as a signal of professionalism, helping smaller consultancies and independent analysts win contracts they could not otherwise bid for.
