Professional indemnity, do you need it?
A plain explainer of what it covers, who it's for, and how it differs from public liability. With one honest note up front.

You sell expertise. Advice, a design, a strategy, a piece of work that a client paid for because they trusted you to get it right. Most of the time you do. But "most of the time" is the part that keeps you up at night, because the one project that goes sideways, the missed detail or the call that turned out wrong, is the one that can land you with a claim that your work cost a client real money.
That is the risk professional indemnity is built for. And the question almost everyone selling a service eventually asks is a fair one: do I actually need professional indemnity, or is it cover I can do without?
Here is the straight explainer, with no scare tactics. And one honest thing first.
The honest bit, up front
careless™ does not offer professional indemnity yet. It is coming, but we are not going to pretend you can buy it from us today.
So treat this guide as exactly what it is: a plain explanation of what the cover does and whether it applies to you, written by people who want to be straight with you rather than sell you something we do not have. If, by the end, you decide professional indemnity is something you want, the one thing you can do here is register your interest so you are first to know the moment it lands.
That out of the way, let's get into it.
What professional indemnity actually covers
Professional indemnity covers the compensation and legal costs that follow when a client claims your professional work cost them money. Not an injury, not broken property, a financial loss they pin on the advice, design, specification or service you delivered.
The key phrase is financial loss caused by your work. In plain terms:
- You give advice, the client acts on it, and it turns out to be wrong. They lose money and hold you responsible.
- A mistake in your design or drawings forces the client to redo expensive work.
- You miss a deadline that was critical, and the client's project takes a financial hit because of it.
- A deliverable you produced does not do what it was meant to, and the client says that failure cost them.
In each case the client can bring a claim, and the bill to defend it lands on you even when the allegation turns out to be unfounded. That last point matters. A lot of professional indemnity claims are about defending work that was actually fine. Defending yourself still costs money, and professional indemnity is what covers that defence as well as any compensation you are genuinely liable for.
Who typically needs it
The simple test: if clients pay you for your knowledge, advice or professional deliverables rather than for a physical product, professional indemnity is the cover that matches your risk.
That sweeps in a lot of people who sell expertise for a living:
- Consultants and advisers of every stripe, from management to IT.
- Designers, design studios and creative agencies producing work clients build on.
- Marketers, PR and advertising agencies running campaigns clients depend on.
- Accountants and bookkeepers, where it is often required by their professional body.
- Coaches and training providers selling guidance and programmes.
- Architects, engineers and surveyors, where a single error can be expensive.
If you recognise yourself in that list, the risk professional indemnity covers is not theoretical. It is the everyday downside of being paid to know things.
For some professions it goes further than a good idea. Regulated bodies, such as those governing accountants and solicitors, require their members to hold professional indemnity. And plenty of larger clients and public-sector frameworks will not appoint you unless you can show a minimum level of cover, so it can be the difference between being eligible to bid and being ruled out before you start.
How it differs from public liability
This is the one people get tangled up in, so here is the clean version.
Public liability covers physical injury and property damage. Someone trips over your equipment and is hurt, or you damage a client's property. It is about harm to a person or a thing in the real world.
Professional indemnity covers financial loss caused by your advice or work. Nobody is hurt, nothing is broken, but the client says your professional work cost them money.
A worked pair makes it obvious. If you are a design studio and a client trips over a cable at your office and breaks their wrist, that is a public liability matter. If that same client says your branding work was so far off-brief it cost them a product launch, that is a professional indemnity matter. Same client, completely different cover.
The two are not interchangeable, and one does not quietly include the other. They sit alongside each other, each handling a different kind of claim. If your work is mostly advice and deliverables, professional indemnity is the one aimed squarely at your exposure. If your work brings you near people and property, public liability is the one for that. Many businesses that sell expertise carry both, because they have both kinds of risk.
When the case for it is weaker
To stay honest in both directions: not every business needs professional indemnity. If you do not sell advice or professional deliverables, if a client could not credibly claim that your work, rather than an accident, cost them money, the core exposure simply is not there.
But be honest with yourself about what you actually sell. Plenty of people describe themselves as "just making things" when, in practice, clients are relying on their judgement and would hold them responsible if that judgement was off. The moment a client is trusting your professional opinion or output to be right, the exposure appears.
A couple of things to understand before you buy any PI
Two quirks of professional indemnity are worth knowing now, whoever you eventually buy it from, because they catch people out.
First, professional indemnity is usually written on a "claims made" basis. That means the policy that responds is the one in force when a claim is made against you, not the one you held when you did the work. The practical upshot: it is important to keep cover running even after a project ends, because a claim can surface long after you delivered.
Second, professional indemnity does not cover everything. It is not there to refund your own fees or pay for redoing your own work, and it does not respond to deliberate or fraudulent acts, or to claims you already knew about before cover started. It covers the genuine, unexpected allegation that your work caused a loss, which is exactly the risk most people worry about.
Related cover, if you're mapping out your risk
Professional indemnity rarely sits on its own. If you are working out what your business actually needs, a few neighbours are worth a look.
Public liability is the cover most often confused with this one, and the one most service businesses pair it with. If you run an agency or manage talent and contracts, the mix of risks is broader again, and our guide to agency insurance maps it out. And if a lot of your work runs through sponsored content and brand partnerships, the specific exposures there are covered in our guide to insurance for brand deals and sponsored content.
Where careless™ fits, and what to do next
You sell your judgement for a living. You do not need a hard sell, you need a straight answer about whether professional indemnity is a cover you should care about, and the honesty to tell you when we cannot help yet.
So here is the plain close. careless™ does not offer professional indemnity today. It is on the way. The covers we do offer are arranged with Kovrilo and underwritten by established insurers, built in plans with a single £25 admin fee and a price you see before you commit, and professional indemnity will join them when it is ready.
If, having read this, you want it, do the one thing that matters: register your interest in professional indemnity. You will be first to know the day it launches, and we will not pretend otherwise in the meantime.
Questions, answered.
If clients pay you for your knowledge, advice or professional deliverables rather than a physical product, professional indemnity is the cover that matches your risk. It is strongly recommended for consultants, designers, agencies, accountants, coaches and anyone selling expertise, and it is often contractually required by larger clients. Some regulated professions, such as accountants and solicitors, must hold it under their professional body's rules.
Not yet, and we will be straight about that. careless™ does not offer professional indemnity today. It is coming, and the most useful thing you can do now is register your interest on our professional indemnity page so you are first to know the moment it launches. There is no quote to get for it here in the meantime.
It covers the compensation and legal costs that follow when a client claims your professional advice, design, specification or service cost them money. That includes honest mistakes, a missed deadline, negligent advice, or a deliverable that caused a financial loss. Crucially, it also covers your legal defence even when the allegation turns out to be unfounded.
Public liability covers physical injury and property damage, someone being hurt or something being broken. Professional indemnity covers financial loss caused by your advice or work, the kind of claim where nobody is hurt and nothing is broken, but the client says your professional work cost them money. They are separate covers and one does not include the other, which is why many service businesses carry both.
