Professional indemnity and directors and officers insurance are both liability covers held by many incorporated businesses, and both respond to claims of things allegedly done wrongly. But they answer two very different questions, and they protect two very different parties. One looks at the work a firm sold to its clients. The other looks at how the people at the top ran the company. Confusing them, or assuming one absorbs the other, can leave either the balance sheet or an individual director's personal assets exposed.

The short version is this. Professional indemnity (PI) protects the firm against claims that its professional services, advice or work were negligent and caused a client a financial loss. Directors and officers (D&O) protects individual directors and officers personally against claims that a wrongful act committed in their capacity as a director or officer breached a duty they owed. PI follows the service sold to clients; D&O follows the management of the company itself.
This guide sets out who each cover protects, what triggers a claim, how each is structured, where they overlap, where they leave a gap, and when a firm needs one, the other or both. It is general information, not advice tailored to any particular business. The cover under any policy is determined by its schedule, insuring clauses and exclusions, and by the underwriter's assessment of the risk. If you are weighing up which covers your business needs, speak to a broker about your own circumstances.
What this comparison is about
Both PI and D&O are third-party liability policies, so at first glance they look like variations on a theme. The crucial difference is the question each is built to answer. PI answers: did the firm's professional work harm a client? D&O answers: did a director's decision or conduct in running the company breach a duty owed to shareholders, creditors, employees or regulators? This is why a firm can hold a large PI limit and still leave its directors personally exposed, and why a company can carry D&O and still have no cover for a botched piece of client work. The rest of this comparison unpacks that distinction and the grey zones where a single set of facts touches both. For a related pairing, see our comparison of professional indemnity versus public liability.
What professional indemnity covers
Who is protected
The firm — whether a sole trader, company, LLP or partnership — together with its partners, directors and employees acting in the course of the firm's professional services. Importantly, PI protects the practice or company balance sheet. It responds to a client's claim against the business, not to a personal claim against an individual for how they governed the company.
What triggers the policy
A third-party claim, usually from a client, alleging that the firm's professional services, advice or work were negligent and caused a financial loss. The common examples are errors, omissions, negligent advice or design, negligent misstatement and breach of professional duty. The defining feature is a client's financial loss flowing from the work itself. You can read more on the underlying cover in our overview of professional indemnity insurance.
Trigger basis
Professional indemnity is usually written on a claims-made basis, subject to a retroactive date. The policy that responds is the one in force when the claim is first made against the firm and notified to the insurer, not the one in force when the work was carried out. Continuity of cover and the retroactive date therefore matter a great deal.
What it does not do
PI does not protect a director's personal assets for a management-duty claim. If the allegation is not about the quality of professional work sold to a client, but about how a director exercised their duties in running the company, PI is generally not the policy that responds.
What directors and officers insurance covers
Who is protected
Individual directors and officers, personally, against claims alleging a wrongful act committed in their capacity as a director or officer. Where the entity itself has securities exposure, cover can extend to the company too, but the heart of D&O is the protection of individuals. You can read more in our overview of directors and officers insurance.
What triggers the policy
An allegation that a director or officer breached a duty owed while running the company. Typical triggers include breach of fiduciary duty, mismanagement, misstatement, breach of duty, and regulatory investigations. D&O also commonly responds to insolvency-related claims — for example wrongful trading under section 214 of the Insolvency Act 1986, and misfeasance claims — and to health and safety and manslaughter defence costs — for example where an individual faces a health and safety prosecution (including under section 37 of the Health and Safety at Work etc. Act 1974) or a gross negligence manslaughter charge, or where directors incur defence costs connected to a corporate manslaughter investigation of the company itself (corporate manslaughter being an offence committed by the organisation, not the individual). The thread running through all of these is a duty owed by the individual in their director or officer capacity, rather than the quality of a service sold to a client.
How the cover is structured — Sides A, B and C
D&O is conventionally arranged in three parts:
- Side A protects individuals directly where the company cannot indemnify them — the classic example being insolvency, when the company is no longer able to stand behind its directors.
- Side B reimburses the company where it has indemnified an individual director or officer, effectively protecting the company's balance sheet for indemnities it has properly given.
- Side C provides entity securities cover — protection for the company itself in respect of securities claims. This is mainly relevant to listed companies.
Trigger basis
Like PI, D&O is written on a claims-made basis. The policy in force when the claim is made and notified is the one that responds, which is why continuity of cover matters here too.
What it does not do
D&O does not cover the cost of redoing negligent client work, and it does not cover a client's financial loss arising from bad professional advice. Those are PI exposures. D&O is about management conduct, not the professional service itself.
Where the two overlap
The overlap is narrower than people expect, but it is real and matters most for advisory businesses. Management consultancy and advisory firms can see a single set of facts trigger both lines: the same engagement can produce an allegation of negligent professional advice, which points to PI, and an allegation of a management failing by a named director, which points to D&O.
The most common shared trigger is a regulatory investigation. A regulator's inquiry can attach to both the firm — engaging PI where the firm's professional conduct is in question — and to named individuals in their director or officer capacity, engaging D&O. Some claims explicitly allege both negligent advice (PI) and a management failing (D&O) arising from the same events. Where a claim straddles the two, the way each policy is worded determines which responds, in what order, and how defence costs are allocated between them. This is precisely the kind of situation where reviewing the two wordings together, before a claim arises, pays off. The overlap between PI and other lines is a recurring theme; our comparison of professional indemnity versus cyber insurance looks at a different but related boundary.
Where they differ
Away from the narrow overlap, the two covers occupy clearly separate territory:
- Whose claim it is. PI responds to a client's claim about the service they were sold. D&O responds to a claim by, or on behalf of, shareholders, creditors, employees or regulators about how a director governed the company.
- Whose assets are protected. PI protects the firm's balance sheet. D&O can protect an individual director's personal assets — notably under Side A, where the company cannot indemnify them.
- The nature of the wrong. PI is about professional negligence in delivering a service. D&O is about a wrongful act in the capacity of a director or officer, such as breach of fiduciary duty, mismanagement or misstatement.
- Personal-asset protection. PI does not protect a director's personal assets for a management-duty claim. D&O does not cover the cost of redoing negligent client work or a client's financial loss from bad professional advice.
- Employment practices. Employment practices liability (EPLI), covering claims such as unfair dismissal or discrimination, is often available as a D&O extension. It is never a PI cover.

Common real-world scenarios
Scenario 1 — Negligent client advice. A consultancy gives a client advice that turns out to be wrong, and the client suffers a financial loss. This is a professional services failure and typically a PI matter. There is no allegation about how a director governed the company, so D&O is not the primary cover.
Scenario 2 — Shareholder claim against a director. Shareholders allege that a director's misstatement in company communications caused them loss. This is a claim against the individual in their director capacity, and typically a D&O matter. PI is not engaged because the allegation is not about a service sold to a client.
Scenario 3 — Insolvency and wrongful trading. A company enters insolvency and a liquidator pursues a director for wrongful trading under section 214 of the Insolvency Act 1986. Because the company cannot indemnify the director, Side A of the D&O policy is the relevant protection. PI does not respond to a management-duty claim of this kind.
Scenario 4 — Regulatory investigation touching both. A regulator investigates an advisory firm's conduct. The inquiry attaches to the firm's professional conduct, potentially engaging PI, and simultaneously names individual directors, engaging D&O. A single event draws on both lines, and how the two wordings interact determines the response and the sharing of defence costs.
Scenario 5 — Health and safety prosecution. After a workplace incident, an individual director faces a health and safety prosecution — and potentially a gross negligence manslaughter charge — while the company itself is investigated for corporate manslaughter (an offence committed by the organisation, not the individual). Defence costs for the named individual are typically a D&O matter. Injury to the employees themselves is dealt with separately under employers' liability insurance, which is compulsory for most UK employers under the Employers' Liability (Compulsory Insurance) Act 1969.
Scenario 6 — Employment dispute. A dismissed employee brings a claim for unfair dismissal and discrimination. This is an employment practices matter, often picked up as an EPLI extension to a D&O or management liability arrangement, and never a PI cover.
When a firm needs both
Some businesses are genuinely exposed on both fronts and commonly carry both covers. Typical examples include:
- Incorporated professional firms with a board, where directors owe management duties as well as the firm owing professional duties to clients.
- Firms with external shareholders or investors, who can bring claims against directors for how the company has been run.
- Businesses with bank covenants or significant creditor relationships, where financial distress can generate creditor and insolvency claims against directors.
- Businesses carrying insolvency risk, where wrongful trading and misfeasance exposures make Side A protection important for individuals.
- Consultancies that both give professional advice and run a company with governance exposure — the classic case where one set of facts can trigger PI and D&O together.
For these firms, holding only PI would leave directors personally exposed on management-duty claims, while holding only D&O would leave the firm without cover for negligent client work.
When one cover suffices
Not every business needs both, and it is worth being clear about when it does not:
- A sole trader with no separate directors and no board rarely needs D&O, because there is little or no director-capacity exposure to insure. If they advise clients, however, they still face a PI exposure.
- A dormant holding company with no client-facing services may need D&O to protect its board against management-duty and regulatory exposure, but may have no PI need because it sells no professional service.
Between these poles sit many businesses whose answer depends on their structure, ownership, creditor position and contractual requirements. The assessment is specific to the individual business, which is why it is worth talking it through with a broker rather than assuming a general rule applies.
How the cover is structured practically
A few structural points are worth understanding before arranging or renewing either line:
- Claims-made continuity. Both PI and D&O are claims-made, so gaps in cover, or an unfavourable retroactive date on the PI side, can leave past matters unprotected.
- The three Sides of D&O. Side A protects individuals where the company cannot indemnify them, Side B reimburses the company for indemnities it has given, and Side C provides entity securities cover, mainly for listed companies.
- Defence costs. How defence costs sit relative to the limit — within it or in addition to it — affects how much protection remains for a settlement. Where a claim spans PI and D&O, the allocation of defence costs between the two policies also comes into play.
- Combined packages are not the same as D&O. A management liability combined package bundles D&O with other lines, commonly EPL, crime, and sometimes PI, in one policy. That is a different thing from a standalone D&O cover, so it is worth knowing exactly what a combined package includes rather than blurring the two.
What to ask when arranging cover
The following questions help frame a conversation with a broker about which covers a business needs:
- Does the firm sell professional advice, design or services that could cause a client a financial loss? If so, is PI in place at an adequate limit?
- Does the company have directors or officers who owe management duties, external shareholders, investors, or a board? If so, is D&O in place?
- Is there any insolvency risk, or are there bank covenants or significant creditors that could generate claims against directors?
- On both the PI and D&O policies, is there continuity of cover, and on PI, what is the retroactive date?
- For claims that could span both lines — such as a regulatory investigation or a management consultancy engagement — how do the two wordings interact and which is intended to respond first?
- Is employment practices exposure relevant, and if so is EPLI arranged as a D&O or management liability extension?
- If a combined management liability package is proposed, exactly which lines does it include, and does it leave PI to be placed separately?
- Are there employees, meaning compulsory employers' liability is required under the Employers' Liability (Compulsory Insurance) Act 1969?
How a broker helps
A broker reviewing both lines maps the business against two separate questions: where the professional services exposure to clients sits, and where the management-duty exposure of individual directors and officers sits. On the PI side, limits are set against the potential financial loss from the work, and retroactive dates and continuity are checked. On the D&O side, the structure across Sides A, B and C is matched to the company's ownership, insolvency risk and regulatory profile, and any EPLI or management liability extensions are considered. Where a single event could engage both policies, the wordings are reviewed together to reduce the risk of a gap or an unhelpful overlap. Apex Insurance Brokers Limited arranges professional indemnity, directors and officers and related commercial covers for UK businesses. The right structure depends on the specific activities, ownership, contracts and risk profile of the firm, so the sensible first step is a conversation about your own circumstances.
FAQ
Is professional indemnity the same as directors and officers insurance?
No. PI protects the firm against claims that its professional work harmed a client; D&O protects individual directors and officers personally against claims that a wrongful act in their director capacity breached a duty. PI follows the service sold to clients; D&O follows the management of the company.
Does professional indemnity protect a director's personal assets?
Generally no. PI protects the practice or company balance sheet against a client's claim. A claim against a named director for a management-duty failing, such as breach of fiduciary duty or wrongful trading, is the territory of D&O.
Can one set of facts trigger both professional indemnity and D&O?
It can, especially for advisory firms. A regulatory investigation can attach to both the firm (PI) and named individuals (D&O), and some claims allege both negligent advice and a management failing. Where a claim straddles the two, the wordings determine which responds and how defence costs are shared.
Does D&O cover the cost of redoing negligent professional work?
No. D&O does not cover the cost of redoing negligent client work or a client's financial loss from bad advice — those are PI exposures. D&O responds to claims that a director breached a duty owed to shareholders, creditors, employees or regulators.
Is D&O the same as a management liability package?
No. D&O is a specific cover for individuals; a management liability combined package bundles D&O with other lines such as EPL, crime and sometimes PI. EPLI is often a D&O extension and is never a PI cover.
Does a sole trader need directors and officers insurance?
Usually not — a sole trader with no separate directors and no board rarely has a director-capacity exposure, though they may still need PI. A dormant holding company with no client-facing services may need D&O but not PI. It depends on the structure; speak to a broker.
