What Does Professional Indemnity Insurance Actually Cover?

Professional indemnity insurance covers the cost of defending a claim that your work caused a client financial loss, plus any compensation awarded against you. For membership organisations, it is a benefit members often ask about directly, usually once a regulator or client asks for proof of cover. Knowing what the policy includes, and what it leaves out, lets an organisation answer those questions with confidence.
Key Takeaways
The policy responds to allegations of negligent advice or work, covering legal defence costs and compensation.
It does not cover injury to employees, injury to the public, or damage to third-party property. Those sit with employers' liability and public liability.
Claims arising from work carried out before the policy's retroactive date are excluded, so continuous cover matters.
Organisations on the Parliament Hill platform can include professional indemnity cover in their member benefits, with cover provided by our partners Marsh Commercial, Caunce O'Hara and Markel Direct.
What Is Professional Indemnity Insurance?
The cover, often shortened to PI or PII, protects a professional when a client alleges that their services were negligent, inadequate, or caused financial loss. The policy responds on the member's behalf, defending the claim and settling it where a settlement is appropriate.
Defence costs are the easiest to overlook. Even where no negligence occurred, proving it takes time and legal fees, and a contested claim can become expensive quickly. A policy that covers defence costs protects a member's finances in the cases they win, not only the cases they lose.
What Does Professional Indemnity Insurance Cover?
PI insurance coverage varies by insurer, and cover, limits and exclusions all differ between policies, so members should read the policy wording before buying. A typical policy pays the legal costs of defending a claim, plus any compensation or costs awarded, where the claim arises from (1):
Professional negligence, such as an error in a piece of work or advice that turns out to be poor.
Unintentional breach of confidentiality, such as sharing sensitive client information without permission.
Unintentional breach of copyright, such as using an image without the right licence.
Defamation and libel, such as remarks about a competitor or client that damage their reputation.
Loss of documents or data belonging to a client.
Loss of money or goods for which the member is responsible.
What Is Not Covered?
Professional indemnity exclusions are where members get caught out, because other policies fill the gaps rather than PI. A membership organisation that explains them clearly saves members from finding out at the point of a claim.
The policy does not cover employee injury. A work-related injury or illness claim from a member of staff falls to employers' liability insurance, a legal requirement for most UK businesses with employees.
It does not cover injury to members of the public or damage to third-party property (1). Where a member's work involves physical interaction with clients, or happens on someone else's premises, public liability is the relevant policy.
The most difficult exclusion is the retroactive date. Claims arising from professional services delivered before the policy started, or before the date from which continuous cover has been held, are not covered. Cover works on a claims-made basis, so the policy in force when the claim is made responds, not the policy in force when the work was done. A member who lets cover lapse between roles or contracts creates a gap that no later policy fills.
How PI Policy Limits Work
The limit of indemnity is the most the insurer will pay, and it is set when you buy cover. Limits are written either on an "any one claim" basis, where the full limit is available for each claim, or on an aggregate basis, where one limit covers every claim in the policy year. Whether defence costs sit inside the limit or in addition to it depends on the wording, and it changes how far the limit stretches.
Client contracts often specify the minimum limit a supplier must hold, so a member's largest client often sets the right figure. Checking contract requirements before renewal avoids having to raise the limit mid-term.
Why This Matters to Membership Organisations
Members rarely ask for a policy outright. They ask whether they are covered, often because a client or professional body wants evidence, and an organisation that can answer the exclusions question becomes the first place they check.
Our platform lets organisations add professional indemnity cover to their member benefits, alongside IT support and a procurement service. Our partners Marsh Commercial, Caunce O'Hara and Markel Direct provide the cover and handle quotes, policies and claims.
Our solutions for professional and trade associations show how partner cover, including optional public and employers' liability, fits into a wider benefits programme.

FAQ
What kind of claims does PI cover handle?
Claims alleging that professional advice or services caused a client financial loss, including negligence, breaches of confidentiality or copyright, defamation, and lost data. The policy covers both the defence and any compensation awarded.
Does professional indemnity insurance cover work done in previous years?
Only back to the policy's retroactive date, or the date from which continuous cover has been held. Because cover is claims-made, a gap in the insurance history leaves that earlier work unprotected. Continuous renewal is what preserves it.
Do members need public liability insurance as well?
Often, yes. PI covers financial loss caused by advice and services. Public liability covers injury to people and damage to property. Members who visit client sites or meet the public usually need both, so it is worth checking which policies they hold before taking on new work.
