Professional indemnity explained: a concise, practical guide for solo business owners. If you give advice, design, consult, or produce deliverables for clients, professional indemnity insurance is the policy many clients and contracts will expect you to hold. It isn't a protection against every business risk; it is specifically designed to cover claims that arise from the professional services you provide. Understand what it does and does not cover, and what to check with a broker, before you buy.
What professional indemnity typically covers and excludes
At a basic level professional indemnity (PI) covers legal costs and compensation awards when a client alleges financial loss because of a mistake, negligent advice, breach of professional duty, error, or omission in the services you supplied. Typical claim scenarios for solos include: incorrect calculations, missing a regulatory deadline, flawed specifications, or advice that led to financial loss.
Common exclusions and limitations you should expect and check include criminal acts, deliberate fraudulent acts, bodily injury and property damage (these are usually excluded or the domain of public or employers liability), contractual penalties or liquidated damages, claims arising from known circumstances before the policy inception, and some cyber-related losses unless expressly included.
- Covered examples: negligent advice, failure to deliver promised service, breach of professional duty leading to client loss
- Common exclusions: fraud, criminal acts, bodily injury/property damage, fines and penalties, pre-existing matters
- Overlap with other covers: public liability covers physical injury/damage; cyber insurance covers data breaches unless PI includes it
Key policy features every solo owner must understand
Insurance policies use specific terms that change the protection you get; small differences matter more for a solo business with limited cash reserves.
Pay particular attention to whether the policy is 'claims-made' or 'occurrence', the retroactive date, whether defence costs are internal or in addition to the limit, territorial and jurisdictional limits, aggregate limits versus per claim limits, excess amounts and how run-off (or tail) cover works if you stop trading or change insurers.
- Claims-made vs occurrence: Most PI is claims-made. It covers claims made during the policy period for incidents after the retroactive date. You must maintain continuous cover or buy run-off on cessation.
- Retroactive date: If the incident occurred before this date, it will not be covered even if the claim is made during the policy period.
- Limit of indemnity: Check whether the stated limit is per claim or an annual aggregate, and whether defence costs erode that limit.
- Run-off/cessation cover: Essential if you stop trading or sell the business; it protects against late claims from past work.
Practical questions to ask your broker before buying
Ask the broker to put answers in writing. A verbal assurance is not a policy term; you want clarity you can refer to if a gap later appears.
- Is this policy claims-made or occurrence-based?
- What is the retroactive date and can it be backdated to cover prior work if needed?
- Are defence costs included within the limit or paid in addition?
- Is the stated limit per claim or an aggregate for the policy period?
- Does the policy include run-off or extended reporting period cover if I cease trading?
- What exclusions are specific to my profession or the types of work I do?
- Does the policy cover subcontractors or consultants I engage, and under what conditions?
- What territorial and jurisdictional restrictions apply to both services and claims?
- How will a prior claim or notification affect my premium and insurability?
- Are there policy conditions tied to contract wording I should be aware of (eg. hold harmless clauses, indemnities)?
- How does the insurer handle defence and settlement decisions? Who controls settlement?
Reducing your exposure as a solo business owner
Insurance transfers some risk, but good practice reduces the chance and cost of claims. For a solo practitioner, a single claim can be disruptive even if ultimately unsuccessful.
- Use clear written contracts that limit liability where commercially reasonable, define scope and deliverables, include reasonable time limits for claims and payment terms.
- Keep meticulous records: client instructions, versions of work, communications, meeting notes and sign-offs. Records materially strengthen your defence.
- Consider limiting high-risk work or charging a premium for it, and use written disclaimers where appropriate without promising unrealistic protections.
- Vet clients and projects for unreasonable contractual demands or payment risk; insist on staged payments and milestone approvals.
- Invest in professional development and show memberships or accreditations to reduce underwriting friction and demonstrate competence.
Buying and managing your policy
Treat PI as a managed business cost. Get at least two quotes from brokers who understand your niche. Compare not just price but limits, wording, exclusions and claims handling reputation. Read the policy schedule and wording before you sign client contracts that require cover.
If you make a claim or become aware of a circumstance that could lead to a claim, notify your insurer immediately and preserve evidence. Late notification can void cover. Review your cover annually or when your services change, and document conversations with your broker. For solo owners, a modest annual premium can buy protection that prevents a single claim from becoming an existential event.
Take these three things away
- Understand it as cover for claims arising from your advice or delivered work
- Check whether cover applies retroactively and matches client contract requirements
- Confirm exact terms with a broker, since these vary by country and insurer
