What is Professional Indemnity Insurance?

Professional indemnity insurance (PII) protects your business if a client claims they have suffered a financial loss as a result of your professional advice, services, or work. It covers the cost of legal defence and any compensation or damages awarded against you.

If your business provides any form of professional service, advice, or design, professional indemnity insurance is likely essential — and in many professions, it is a legal or regulatory requirement.

What Does PII Cover?

Professional indemnity insurance typically covers claims arising from:

• Negligent advice — Providing incorrect or misleading guidance that causes a client financial loss
• Professional errors — Mistakes in your work, such as calculation errors, design flaws, or incorrect data
• Breach of professional duty — Failing to meet the standard of care expected in your profession
• Breach of confidentiality — Accidentally disclosing sensitive client information
• Loss of documents or data — Losing or damaging client files in your care
• Intellectual property infringement — Unintentionally using someone else’s protected work
• Defamation — Allegations of libel or slander in the course of professional activities

What PII Does Not Cover

• Deliberate wrongdoing — Intentional fraud, criminal acts, or wilful negligence
• Bodily injury or property damage — These are covered by public liability insurance or employers’ liability insurance
• Product liability — Claims about defective physical products
• Employment disputes — Claims from employees (covered by employment practices liability insurance)

Who Needs Professional Indemnity Insurance?

Legally or Regulatorily Required

Some professions in the UK must carry PII by law or regulatory requirement:

Strongly Recommended

Even where PII is not legally required, it is strongly advisable for:

• IT consultants and software developers — Bugs, system failures, or data breaches can cause significant client losses
• Management consultants — Strategic advice that leads to poor outcomes
• Marketing and advertising agencies — Campaigns that cause reputational or financial harm
• Recruitment agencies — Placing unsuitable candidates
• Freelancers and contractors — Many clients require PII as a condition of engagement
• Training providers — Incorrect or inadequate training causing harm or loss

Many clients and contracting organisations will not work with you unless you can demonstrate adequate PII cover, regardless of whether your profession legally requires it.

How Much Does PII Cost?

Premiums depend on several factors:

Typical annual premiums for small UK businesses range from £150 to £1,500 for lower-risk professions with modest turnover. High-risk professions, large firms, or those with claims history can pay significantly more.

Key Policy Terms

Limit of Indemnity

The maximum amount the insurer will pay for any single claim or in aggregate during the policy period. Common limits range from £100,000 to £5 million, though some professions require higher. Your limit should reflect the largest potential claim you could face.

Excess (Deductible)

The amount you pay towards each claim before the insurance kicks in. A higher excess reduces your premium but increases your out-of-pocket cost when a claim arises.

Claims-Made Basis

PII operates on a claims-made basis, meaning it covers claims made during the policy period, regardless of when the alleged negligence occurred. This is different from “occurrence-based” policies. The implication is:

• You must have a policy in force when the claim is made, not just when the work was done
• If you stop trading or let your policy lapse, you need run-off cover to protect against claims arising from past work
• Run-off cover is typically required for 6 years (the limitation period for most contractual claims)

Retroactive Date

Some policies only cover work done after a specified retroactive date. Work done before that date is excluded. When switching insurers, ensure your new policy’s retroactive date does not create a gap.

How to Choose the Right Policy

1. Assess your exposure — Consider the types of work you do, the size of your contracts, and the potential consequences of errors
2. Check regulatory requirements — Verify the minimum cover your profession requires
3. Choose the right limit — Your limit of indemnity should cover your largest contract value or potential claim
4. Compare quotes — Use a specialist insurance broker who understands your profession
5. Read the policy wording — Understand exclusions, conditions, and notification requirements
6. Declare everything — Disclose any previous claims, complaints, or circumstances that might give rise to a claim. Non-disclosure can void your policy.

Making a Claim

If you become aware of a potential claim or receive a complaint:

1. Notify your insurer immediately — Most policies require prompt notification of any claim or circumstance that might lead to a claim
2. Do not admit liability — Let your insurer handle communications and negotiations
3. Gather documentation — Collect all relevant contracts, correspondence, and records
4. Cooperate with the insurer — Provide all requested information promptly

Proper accounting records and documentation of client work make it much easier to defend against claims.

PII and Business Structure

The cost of professional indemnity insurance is an allowable business expense for tax purposes. Premiums appear in the profit and loss account as an operating cost.

If your business is a limited company , the company itself holds the PII policy. For sole traders and partnerships, the individuals are the policyholders. The level of cover you need may also influence whether you choose to trade through a limited company, as the corporate structure provides an additional layer of protection.
