Category: PI comparison · Reviewed by Mark Fox, Broker · Renewals · Last reviewed May 2026
Professional Indemnity (PI) and Directors and Officers (D&O) insurance are sometimes treated as alternatives, sometimes as complements, and sometimes confused. They sit on the same shelf at the broker — both are claims-made liability covers, both pay defence costs, and both are bought by professional firms — but they answer fundamentally different exposures. PI insures the firm against client allegations that its professional services were negligent. D&O insures the individuals who run the business against allegations directed at them personally for the way they have managed the company.
This article sets out the mechanical differences between PI and D&O, the structural features of each (including the Side A, B and C distinction within D&O), and the overlap zones where careful coordination matters.
The comparison is not about which line a firm “should” buy — that depends on the firm’s activities, ownership structure, regulatory position and contractual obligations. The comparison is about how the two policies are constructed, what they respond to, and where firms commonly find that one line answers an exposure the other does not.
Many regulated firms hold both. Many SMEs without external investors or regulatory scrutiny hold only PI. Some firms (particularly small private companies) hold only D&O because their work does not involve a duty of care to clients but their directors face exposure from creditors, employees and HMRC.
The boundaries between PI, D&O and broader Management Liability covers can shift between insurers and between wordings. The same allegation can sometimes be presented to two policies, depending on how it is pleaded and how the wordings define the insured persons and the covered conduct. Names also vary — “Management Liability” packages often bundle D&O with Employment Practices Liability and Crime cover, and some PI wordings include an element of entity cover that resembles Side C D&O.
This article describes typical market features. The cover under any specific policy is defined by its schedule, insuring clauses and exclusions.
The named insured is the firm — the company, LLP or partnership carrying on the professional service. Partners, directors and employees are usually included as additional insureds when acting in the course of the firm’s business. Some wordings extend cover to sub-contractors and to predecessor firms.
PI responds to a third-party claim alleging civil liability arising from the conduct of the insured’s professional services. Negligence, breach of duty, breach of contract, dishonesty of employees, libel, slander and intellectual property infringement are commonly covered, subject to the specific insuring clause.
Defence costs are commonly covered in addition to the limit of indemnity. Some wordings include them within the limit, in which case legal fees erode the amount available to settle the claim.
PI is claims-made and notified. The policy responds to claims first made against the insured and notified to insurers during the period of insurance (or any agreed extended reporting period), subject to the retroactive date.
Limits are commonly “any one claim” and/or “in the aggregate”. Specific regulated professions have minimum limits set by their professional body — for example solicitors, architects and accountants.
Loss of documents, dishonesty of employees, court attendance compensation and run-off cover are commonly available.
Bodily injury and property damage are typically excluded. Insolvency, fraudulent conduct by the principals, fines and penalties, and assumed contractual liability beyond the insured’s professional duty are typically excluded.
The insured persons are the directors and officers of the company. The company itself is the named entity but, importantly, the cover is for the individuals — including past, present and future directors and officers, and (under most modern wordings) employees acting in a managerial or supervisory capacity. Cover may also extend to outside directorships held by directors at the company’s request.
Modern D&O policies are typically structured around three insuring agreements:
D&O responds to third-party claims alleging a “wrongful act” by an insured person — that is, an act, error, omission, misstatement, misleading statement, neglect or breach of duty committed in the capacity of director or officer. Claimants are typically shareholders, regulators, creditors, employees, liquidators or other third parties asserting that the conduct of management has caused loss.
Defence costs sit at the heart of D&O cover and are typically advanced in addition to the limit of indemnity (or within, depending on wording). Investigation costs — including costs of responding to formal regulatory investigations before any claim has been brought — are commonly covered.
D&O is claims-made and notified. As with PI, the date of the underlying alleged wrongful act is generally not determinative of which policy responds; what matters is when the claim is first made and notified.
D&O limits are commonly written “in the aggregate” with sub-limits for investigation costs, securityholder demands and other categories. Side A often carries an additional excess limit available only when Side B and C are exhausted or unavailable.
Investigation costs, derivative demand investigation, crisis communication costs, regulatory investigation costs and extradition costs are commonly available extensions or in-built features.
Bodily injury and property damage are commonly excluded. Conduct exclusions (fraud, dishonesty, personal profit) typically operate only after final adjudication. Insured-vs-insured exclusions limit claims between insured persons (subject to common carve-outs for derivative actions and employment claims).
There are zones in which a claim might be presented to either policy:
| Dimension | Professional Indemnity (PI) | Directors and Officers (D&O) |
|---|---|---|
| Trigger basis | Claims-made and notified | Claims-made and notified |
| Nature of third-party claim | Financial loss from negligent professional services | Loss to claimants alleging wrongful act by directors or officers |
| Who is the insured | The firm; partners, directors, employees acting in the business | The directors and officers personally (Side A/B); the company within defined scope (Side C) |
| Who typically brings the claim | Clients of the firm | Shareholders, regulators, creditors, employees, liquidators |
| Defence costs | Commonly in addition to limit | Commonly advanced; investigation costs often built in |
| Limit structure | Any one claim and/or in the aggregate | Typically aggregate, with sub-limits and (often) additional Side A limit |
| Common exclusions | Bodily injury, property damage, fraud, insolvency, fines | Bodily injury, property damage, conduct exclusions post-adjudication, insured-vs-insured |
| Retroactive date | Often applies | Often applies |
| Run-off cover | Commonly required on cessation/merger | Commonly required on M&A and cessation |
| Structural sub-covers | None standard | Side A, B, C; investigation costs |
Scenario 1 — Shareholder oppression suit. A minority shareholder sues the directors of an owner-managed company alleging unfair prejudice and breach of fiduciary duty. The allegation is directed at the directors in their managerial capacity. D&O is the policy commonly looked to. PI would generally not be engaged because there is no professional service owed to the shareholder by the firm.
Scenario 2 — Audit firm sued for negligent audit. An audit firm is sued by a client (or a third party relying on the audit) for losses arising from negligent audit work. The allegation concerns the firm’s professional service. PI is the policy commonly looked to. D&O could be engaged in parallel if the audit partner is also alleged to have managed the engagement negligently in a way that goes to their conduct as a director.
Scenario 3 — HMRC investigation of director’s tax conduct. A director is the subject of an HMRC investigation arising from the company’s tax affairs. Investigation cost cover under D&O may respond, depending on the wording. PI is generally not engaged because the allegation is not against the firm for its professional services.
Scenario 4 — Insolvency and wrongful trading claim. A liquidator pursues directors of a professional services firm for wrongful trading. D&O is the policy commonly looked to. If allegations are also pleaded that include negligent professional services, PI may have a role, but the wrongful-trading allegation itself sits on D&O.
Scenario 5 — Regulatory enforcement against firm and named individuals. A regulator opens enforcement proceedings against a firm and names two of its directors as personally responsible. The firm’s defence costs may attract PI (depending on whether the regulatory action arises from professional services) and the directors’ costs may attract D&O. Coordination between the two policies — and avoidance of double payment or coverage gap — is a placement question.
Firms that are FCA-regulated, hold external investors, have a complex group structure, employ a significant workforce or operate in sectors with regulator scrutiny commonly hold both PI and D&O. Owner-managed firms with regulatory exposure (financial advisers, accountants, solicitors, healthcare practices) commonly hold both because the regulator can pursue both the firm (PI) and the individuals (D&O).
A sole trader without employees, without external investors and with no regulatory exposure to individuals may face limited D&O exposure and may hold PI alone. A holding company with no professional services activity but with directors exposed to creditor or regulator action may hold D&O alone. Most active SMEs sit somewhere between, and the placement decision is sensitive to facts.
Where both lines are placed, a broker can review the wordings together to map allocation in advance, identify gaps where one policy excludes what the other does not include, and align limit structures with the firm’s exposure profile. Apex Insurance Brokers Limited arranges PI, D&O and Management Liability cover for UK firms; the right structure for any individual firm depends on its activities, ownership and regulatory position.
Is D&O the same as Management Liability? D&O is one component. Management Liability is a package that typically bundles D&O with Employment Practices Liability and Crime cover, and sometimes Pension Trustee Liability.
Does PI cover directors personally? PI typically covers partners, directors and employees when acting in the course of the firm’s professional services. It does not usually respond to allegations against directors in their managerial capacity — for example shareholder claims, regulator actions against individuals or insolvency claims.
Does D&O cover the firm against client negligence claims? D&O Side C may provide entity cover for defined categories (commonly securities claims). It does not usually respond to client claims alleging negligent professional services — that is the territory of PI.
Are both PI and D&O claims-made? Yes. Both are typically written on a claims-made and notified basis, and both commonly carry a retroactive date.
What is Side A cover? Side A pays loss directly to insured persons where the company is unable or not permitted to indemnify them — typically in cases of insolvency or where indemnification is prohibited by statute or the company’s articles.
Do owner-managed companies need D&O? Owner-managed companies still face D&O exposure — for example from HMRC investigations, employee claims, creditor actions on insolvency or disputes between owners. Whether D&O is appropriate depends on the specific exposures and the firm’s risk appetite.
Can one policy cover both PI and D&O? Some insurers offer combined PI and Management Liability schedules for certain SME sectors. Standalone placements remain common, particularly for regulated firms with specialist PI wordings.
Does D&O cover employment disputes? Pure D&O typically does not. Employment Practices Liability — a separate cover, often packaged with D&O within a Management Liability product — responds to employment claims.
