Professional Indemnity Insurance: A Guide for Professionals and Consultants

Professional indemnity (PI) insurance protects individuals and firms against claims arising from professional negligence, errors, omissions, or breach of duty in the course of providing professional services. For solicitors, accountants, financial advisers, architects, surveyors, management consultants, and a wide range of other professionals, PI cover is either legally mandated by a regulatory or professional body, or is an essential commercial safeguard without which professional practice would be imprudent.

This guide explains how PI insurance works, the key structural features professionals need to understand, minimum cover requirements imposed by the main regulators and professional bodies, and how the cover interacts with overseas professional activities. It is not personal advice; the appropriate PI structure for your practice requires specialist assessment by a qualified insurance broker with professional indemnity expertise.

What Professional Indemnity Insurance Covers

A PI policy indemnifies the insured against legal liability arising from claims by third parties — typically clients or former clients — who allege that the professional has been negligent, has made errors or omissions, or has breached professional duty, and that this has caused them a financial loss.

Covered categories typically include:

• Negligence: Failing to exercise the standard of care expected of a competent professional in the same field.
• Errors and omissions: Mistakes in advice, documentation, calculations, or professional work.
• Breach of professional duty: Acting contrary to the standards of the profession, including confidentiality, conflicts of interest, and fiduciary obligations.
• Defamation: Allegations of libel or slander arising from professional communications (in some PI policies).
• Intellectual property infringement: Unintentional infringement of third-party IP in the course of professional work.
• Loss of documents: Loss or destruction of client documents in the professional's custody.

Most PI policies include the cost of defending claims, even where those claims are ultimately unsuccessful. The insurer typically appoints solicitors to manage the defence, which is an important protection in its own right — professional negligence defence is complex and expensive.

Claims-Made Versus Occurrence Basis

This is perhaps the most important structural distinction in PI insurance, and one that practitioners must understand clearly.

Claims-made policies respond to claims that are made (i.e., notified to the insurer) during the period of insurance, regardless of when the professional act giving rise to the claim occurred. If you are insured in 2026 and a claim is made in 2026 for work you did in 2020, your 2026 policy responds — provided the policy has retroactive cover extending back to 2020.

Occurrence policies respond to claims where the professional act (the negligence or error) occurred during the period of insurance, regardless of when the claim is made. Occurrence policies are less common in PI insurance than in general liability, but do exist in some markets.

The claims-made basis is standard in the UK PI market. Understanding this basis is essential because:

1. Your current insurer's policy covers you only while it remains in force. If you cancel without purchasing run-off cover, you may be uninsured for future claims about past work.
2. The retroactive date determines how far back your cover extends. A policy with a retroactive date of 2018 will cover claims made today about work done in 2020, but not claims about work done in 2017.

The Retroactive Date

The retroactive date is the earliest date from which the policy provides cover for past professional acts. When a professional first takes out PI insurance, the retroactive date is typically set as the policy inception date (no retroactive cover). Over time, as the insurer renews the policy, the retroactive date remains fixed — and the cover period for past work extends.

If you switch insurers at any point, the new insurer's retroactive date becomes critical. A new insurer unwilling to back-date to your original retroactive date leaves a gap: work done before the new insurer's retroactive date is uninsured on the new policy, and uninsured on the old policy (which has lapsed). This is a serious and common problem when professionals switch insurers without professional guidance.

To protect against this:

• Maintain continuity with the same insurer where possible, or ensure the new insurer matches or extends beyond the existing retroactive date.
• If changing insurers, consider purchasing a tail period (run-off cover) on the old policy as an additional safeguard.
• Document and retain your retroactive date in your practice records.

Run-Off Cover: The Critical Retirement and Cessation Risk

When a professional ceases practice — retires, sells their business, changes careers, or closes their firm — the PI risk does not immediately disappear. A client can bring a claim years or even decades after the professional act. Without ongoing cover, there is nothing to respond to that claim.

Run-off cover (also called tail cover) continues PI protection after the professional has ceased practice. It is written on a declining premium basis — typically 100% of the last year's premium for years one and two, reducing to 50% and then 25% over subsequent years — and most regulators require a minimum run-off period.

Key points on run-off:

• SRA (Solicitors Regulation Authority): Requires a minimum run-off period of six years for solicitor firms that close. The run-off policy must meet the SRA's Minimum Terms and Conditions.
• ICAEW and ACCA (accountancy bodies): Require continuing PI cover for a period after cessation of practice, typically five to six years, meeting the body's prescribed minimum terms.
• FCA (Financial Conduct Authority): Regulated firms ceasing regulated activities must ensure ongoing PI cover to meet FCA requirements for any outstanding client obligations.

Failing to arrange adequate run-off cover can result not only in personal financial exposure, but in regulatory sanctions and the loss of the right to practise if the professional ever seeks to resume.

Regulatory Minimum Cover Requirements

The main UK professional regulators impose minimum PI insurance requirements on regulated practitioners. These minimums should be treated as floors, not targets — they often do not reflect the scale of the firm's actual exposure.

Solicitors (SRA): Minimum £2 million per claim for sole practitioners and partnerships with two or more partners; £3 million per claim for incorporated entities. No aggregate limit on the number of claims. Cover must be placed with an SRA-approved insurer and meet prescribed Minimum Terms and Conditions. Premiums can be significant for high-risk practice areas such as conveyancing and litigation.

Accountants (ICAEW/ACCA): Minimum PI cover requirements are scaled to turnover. ICAEW's guidance recommends cover of at least £100,000 for the smallest practices and substantially higher amounts for larger or specialised firms. Cover must be with a reputable insurer and maintained for the duration of practice.

Independent Financial Advisers (FCA): Personal investment firms must hold PI cover meeting the minimum limits set out in IPRU-INV 13, which follow the Insurance Distribution Directive levels — currently a minimum of €1,300,380 for a single claim and €1,924,560 in aggregate per year (with higher requirements scaled to relevant income, and adjustments where the firm holds client money or has past business). Limits set in a currency other than euros must be at least equivalent at inception and renewal. The FCA can and does review PI arrangements as part of firm supervision; inadequate PI cover can trigger regulatory action.

Architects (ARB/RIBA): £250,000 minimum, but the majority of architectural practices carry significantly higher limits reflecting the scale of projects they undertake.

Consulting engineers and surveyors: Professional bodies (RICS, ICE, IStructE) specify minimum cover levels that vary by project type and firm size.

Firms carrying only the regulatory minimum may find that a single large claim — particularly in high-value conveyancing, complex financial advice, or major construction — exhausts the cover and leaves a shortfall. Excess layers should be considered where the practice handles high-value transactions.

Coverage for Overseas Professional Activities

The globalisation of professional services means that many UK-based professionals deliver advice and services to clients in other jurisdictions — managing international investments, advising on cross-border mergers, providing tax or legal advice that applies foreign law.

Standard UK PI policies typically cover professional services provided from a UK base to clients anywhere in the world, subject to jurisdiction exclusions. Common exclusions include claims brought in the United States and Canada: US litigation risk is so significant (high damages, contingency fees, class actions) that most UK PI insurers exclude it or charge substantially higher premiums for US coverage.

For professionals who regularly work with US clients or provide services that could give rise to US-law claims, a specialist US professional liability cover or a Lloyd's policy with US coverage is required.

For professionals practising in other jurisdictions — holding foreign practising certificates, working for overseas firms, or providing advice under foreign law — the question of whether UK PI cover follows them abroad is complex. Regulatory requirements in the overseas jurisdiction may require local PI cover in addition to, or instead of, UK cover.

Expatriate professionals should confirm with their PI broker whether:

• Their UK policy covers claims arising from work performed or advice given in the overseas jurisdiction.
• The insured country's regulators accept UK PI cover as meeting their requirements.
• Local cover is mandated for the overseas practice.

Contractor and Consultant PI Cover

Independent consultants and contractors — individuals providing professional services without the structure of a regulated firm — are sometimes uncertain whether PI insurance applies to them. It does, and in many cases it is just as important as for regulated professionals.

If you provide advisory, consultancy, design, technical, or other professional services under a contract — whether as an individual, through a limited company, or through a personal service company — and a client claims that your work caused them a financial loss, they can bring a claim for professional negligence. The claim will be directed at you personally (or your company) rather than at an employer.

Many commercial clients now require evidence of PI cover at a minimum limit before awarding contracts. Relevant sectors include IT consultancy, management consulting, HR consulting, financial modelling, engineering contracting, and medical or clinical consulting.

Interaction with Other Liability Covers

PI insurance covers professional liability — the specific liability arising from professional services. It complements, but does not replace:

Public Liability (PL): Covers bodily injury and property damage to third parties arising from your general business activities (e.g., a client tripping over a cable at your premises). PL does not cover professional negligence.

Employers' Liability (EL): Legally required if you employ staff. Covers injury to employees.

Directors' and Officers' Liability (D&O): Covers personal liability of directors and officers for management decisions. This is a related but distinct cover from PI.

Cyber Liability: Increasing importance for professionals handling large volumes of client data. PI policies may cover some cyber-related professional claims (e.g., data breach caused by a firm's negligence), but dedicated cyber cover is typically required for the full range of cyber exposures.
