In this guide
Professional liability insurance pays to defend you, and pays damages, when a client says your advice or work cost them money. For consultants it is usually the most important policy to carry, because general liability does not cover that kind of claim. It is also called errors and omissions insurance, or E&O.
The short version:
- It covers claims of negligence, mistakes, missed deadlines, and bad advice in your professional services.
- General liability covers injuries and property damage, not financial loss from your work.
- Most policies are “claims-made”: the policy in force when the claim arrives is the one that responds.
- Many client contracts require it, often with a stated minimum limit.
This is general information, not insurance or legal advice. Policy terms vary by insurer, so review any policy with a licensed insurance professional.
What it covers
A professional liability policy typically responds when a client alleges:
- Negligence or errors. Your analysis, design, or recommendation was wrong and the client lost money acting on it.
- Omissions. You left out something you should have done or disclosed.
- Failure to deliver. You missed a deadline or did not finish what the contract promised.
- Misrepresentation. A client says you overstated what you or your work could do.
It pays for your legal defence, which matters even when the claim has no merit, and for settlements or judgments up to the policy limit. The Insurance Information Institute describes it as protection against claims of negligence or failure to perform professional services.
What it does not cover
- Bodily injury and property damage. A client who trips over your laptop cable is a general liability claim.
- Employee injuries. That is workers’ compensation.
- Data breaches. Usually a cyber policy, though some technology E&O forms combine the two.
- Intentional or criminal acts. Fraud and deliberate wrongdoing are excluded.
- Guarantees you made in a contract that go beyond ordinary professional care, depending on the wording.
Professional liability, E&O, and malpractice
They are the same kind of insurance under different names. “Malpractice” is used for doctors and lawyers, “errors and omissions” for technology, real estate, and insurance professionals, and “professional liability” as the general term. A consultant shopping for any of the three is shopping for the same thing.
How claims-made coverage works
Most professional liability policies are claims-made, and this trips people up.
A claims-made policy covers a claim only if two things are true: the claim is made while the policy is in force, and the work that caused it happened after the policy’s retroactive date. The retroactive date is usually the day you first bought continuous coverage.
Three consequences:
- Do not let coverage lapse. If you cancel and a claim arrives later about old work, there is no policy to respond.
- Keep your retroactive date when you switch insurers. Ask the new insurer to match it, or your past work becomes uninsured.
- Buy tail coverage if you stop. An extended reporting period, known as a tail, lets you report claims after the policy ends. It matters if you retire or close the business.
Do consultants actually need it?
No law requires most consultants to carry it. In practice you need it if:
- a client contract requires it, which is common with larger companies and government work;
- your advice influences decisions with real money at stake;
- a single lawsuit, even an unfounded one, would be hard for the business to pay for.
Forming an LLC does not remove the need. The LLC protects your personal assets from business debts, but it does not protect the business itself, and you can still be personally liable for your own professional negligence. Our guide to LLC insurance cost covers how the two fit together.
What drives the price
Insurers look at:
- What you consult on. Financial, engineering, and technology advice carry more risk than, say, marketing.
- Revenue. More work means more exposure.
- Limit and deductible. A common starting limit is $1 million per claim; a higher deductible lowers the premium.
- Claims history.
- Contracts. Written agreements with a clear scope and limits on liability reduce risk.
- Experience and any professional credentials.

How to choose a policy
- Check that the definition of “professional services” matches what you actually do. A narrow definition is the commonest gap.
- Confirm the retroactive date.
- Ask whether defence costs are inside or outside the limit. Inside means legal fees reduce what is left for a settlement.
- Check whether you have the right to refuse a settlement, and what happens if you do.
- Match the limit to the largest requirement in your client contracts.
- Look at what is excluded, especially anything close to your core work.
Frequently asked questions
Is professional liability the same as general liability?
No. General liability covers bodily injury and property damage to others. Professional liability covers financial loss a client blames on your services. Many consultants carry both; our guide to general liability insurance covers that side.
Is errors and omissions insurance the same as professional liability?
Yes. They are two names for the same coverage.
Do independent consultants and freelancers need it?
If your contracts require it or your advice could cost a client money, yes. Being a one-person business does not reduce the risk of a claim.
What limit should a consultant carry?
A $1 million per-claim limit is a common starting point. Carry at least what your largest client contract demands.
What is tail coverage?
An extended reporting period that lets you report claims after a claims-made policy ends, for work done while it was active.
