Professional Liability.
General liability covers someone getting hurt. This covers someone losing money because of your work.
If you are paid for expertise rather than goods, this is the policy that matters most and the one most owners
buy last. An allegation of professional negligence is expensive to answer whether or not it has merit, and
general liability will not contribute a dollar toward it.
It also works differently from every other policy you hold.
Professional liability is claims-made, so it protects you based on when a claim is reported rather than when the
work was done. Retroactive dates and tail coverage decide whether years of past work stay protected, and getting
them wrong is the most common and most costly mistake in this line.
Physical harm versus financial harm
The distinction is simple once stated and almost never explained at the point of sale. Every example below falls entirely outside a general liability policy.
A recommendation that cost money
A consultant advises a strategy, the client loses revenue, and the client alleges the advice was negligent. No injury, no property damage, no general liability response.
A missed deadline or filing
An accountant misses a filing date, a lawyer misses a limitation period, an agency misses a launch. The loss is financial and the exposure is entirely professional.
A defect in work delivered
Software that fails in production, a design that does not perform, a report with an error carried into a client decision. The damage is to their business, not their property.
A claim with no merit at all
Most professional claims are disputed and many are dismissed. Defence still runs to real money, and this is the policy that funds it.
Claims-made, retroactive dates, and tail
This is the part that behaves unlike anything else you insure, and the part where a cheaper quote is frequently a worse policy.
How claims-made works
Your general liability policy responds to what happened while it was in force. Professional liability responds to what is reported while it is in force. Those are very different promises.
Do excellent work in 2023, stay insured through 2026, and a claim arriving in 2026 is covered. Do the same work and let the policy lapse in 2025, and the claim arriving in 2026 is yours to fund, even though you were fully insured the entire time you performed the work.
That is why continuity matters more here than price. A gap of even a few weeks between policies can strand years of completed work.
Retroactive date and tail
The retroactive date is how far back your coverage reaches. A policy bought today with today's retroactive date protects nothing you have already delivered. A policy carrying a retroactive date from when you started trading protects all of it.
When you change carriers, that date must be carried across. A quote that quietly resets it to today may look cheaper and has silently cancelled years of protection. This is the single most important thing to check on any competing quote.
Tail coverage is the other side. When you retire, sell or stop practising, tail lets claims still be reported after the policy ends. Without it, closing the policy closes protection on everything you ever did.
If you sell judgement, you need this
Consultants and agencies
Strategy, marketing, design, recruitment, management consulting. Deliverables are opinions and outcomes, which is exactly what gets disputed.
Technology and software
Failed implementations, downtime, data handling, missed specifications. Client contracts in this sector almost always require it, and often at high limits.
Accountants and financial services
Filing errors, misstatements, advice that produced a loss. Frequently required by regulators and professional bodies as well as clients.
Architects, engineers and construction professionals
Design errors carry long exposure because problems surface years later. Retroactive dates and tail matter more here than almost anywhere.
Real estate and insurance professionals
Disclosure failures, misrepresentation, placing the wrong cover. Usually a licensing requirement rather than a choice.
Healthcare and allied practitioners
Medical malpractice is professional liability applied to clinical work, with its own carriers and its own rules.
Where two policies stop being alike
Professional liability quotes vary far more in substance than in price. These are the terms that decide whether a policy actually helps you on the day.
Do defence costs erode the limit?
On many professional liability policies, legal fees come out of the limit rather than sitting on top. A long dispute can consume most of the coverage before settlement. Ask this before you compare premiums.
The retroactive date
Full prior acts, or today? This one line can be the difference between years of protection and none, and it rarely appears on a quote summary.
What the definition of professional services says
The policy only responds to services it defines. If your work has broadened since the policy was written, the wording may no longer describe what you actually do.
Consent to settle
Some policies let the insurer settle without your agreement, which can matter in a profession where an admission damages reputation. A hammer clause changes the balance and is worth understanding.
Sub-limits and exclusions
Regulatory investigations, subcontractor work, contractual liability and specific client types are frequently sub-limited or excluded. Cheap quotes are often cheap here.
Cyber overlap
Data handling claims can fall between professional liability and cyber. Where both are held, the two policies should be written to work together rather than each pointing at the other.
How we place professional liability
We start with what you actually deliver and how the contracts are written, because the definition of professional services in the policy has to match it. That is a wording exercise rather than a pricing one, and it is where most inadequate policies are created.
Then we protect continuity. If you hold cover already, we carry the retroactive date across rather than resetting it, and we make sure there is no gap between the policies. Where you are retiring or selling, we arrange tail before the policy ends rather than after.
We also read your client contracts for the limits and terms they demand. Technology and construction clients in particular specify high limits and specific wording, and matching it up front avoids losing work over paperwork.
And we place it in the specialist markets rather than wherever a general carrier will take it. Appetite in this line is narrow and highly sector-specific, which is where breadth of carriers earns its keep.
Ask what the retroactive date is.
A cheaper policy that resets it to today has quietly cancelled protection on every project you have already delivered. It is the least visible and most expensive way to save money in this line.

What is the difference between professional liability and general liability?+
General liability covers physical harm: someone is injured or their property is damaged. Professional liability covers financial harm caused by your work, advice or service. If a client sues because your recommendation cost them money rather than because they tripped in your office, general liability does not respond.
Who needs it?+
Anyone paid for expertise, judgement or a service rather than a physical product. Consultants, accountants, IT and software firms, marketing agencies, architects and engineers, real estate professionals, recruiters, coaches, and healthcare providers. Increasingly, client contracts require proof of it before work begins.
What is a claims-made policy?+
Professional liability is almost always claims-made, which is fundamentally different from general liability. It responds to claims reported while the policy is active, not to work performed while it was active. Let the policy lapse and claims about past work are no longer covered, even though you were insured when you did the work.
What is a retroactive date?+
The date from which past work is covered. Buy a policy today with a retroactive date of today and only work done from today forward is protected; everything you have already delivered is uninsured. Keeping the retroactive date intact when you change carriers is one of the most important things an advisor does for you.
What is tail coverage?+
An extended reporting period that lets you report claims after the policy ends. It matters enormously when you retire, sell the business, or stop practising, because claims often surface years after the work. Without tail cover, closing your policy closes your protection on everything you ever did.
Do defence costs come out of my limit?+
Frequently yes on professional liability, unlike general liability where defence is often paid on top. If defence erodes the limit, a long dispute can consume much of your coverage before any settlement. It is one of the most important differences between two policies that look similar on price.
Does it cover claims that turn out to be baseless?+
Yes, and that is much of the value. Defending a professional negligence allegation is expensive whether or not it has merit, and most policies respond to the allegation rather than the outcome. Many claims are ultimately dismissed and still cost a great deal to answer.
Is E&O the same as professional liability?+
Broadly yes. Errors and omissions is the term used more often in financial services, insurance, real estate and technology; professional liability is used more in consulting and licensed professions. Medical malpractice is the same concept applied to healthcare. The mechanics are the same.
