What is Professional Indemnity Insurance? Your Complete Guide

If you’re running a business, offering expert advice or providing a service where your work can be questioned, you’ve probably heard of professional indemnity insurance (or PI insurance).

But what is professional indemnity insurance? Do you really need it? And what does it cover, anyway?

In short, PI insurance protects you if your work or advice causes financial loss to a client. It helps cover legal fees, compensation costs and other expenses if you’re faced with a claim of incorrect advice or professional negligence.

If disagreements happen, PI insurance helps cover the cost of making things right.

In this guide, you’ll find everything you need to understand Professional Indemnity Insurance. We’ll explain what PI insurance is, who should have it, and how much it costs. So you can choose the best insurance for your business.

What is professional indemnity insurance?

Professional Indemnity is a type of business insurance that protects individuals and companies from the costs of claims relating to mistakes in their professional services.

The main purpose of PI insurance is helping businesses cover the costs of defending professional legal claims. It also covers compensation payouts if you’re at fault. Essentially, it acts as a safety net to protect your business if a client claims you’ve made a mistake causing them financial loss.

If you provide advice or deliver a service where there's a risk things could go wrong, this type of cover is for you. From financial advisors to architects, digital marketers and solicitors, professional mistakes happen. It’s just part of life. But PI helps put things right.

What does professional indemnity mean?

Professional indemnity protects businesses from the costs of claims against their work or services. It’s also known as “Errors and Omissions Insurance” in US markets. But whatever the name, it means the same.

Let’s break it down.

• The “professional” part of professional indemnity refers to any individual or business providing paid services or advice. This could be a freelancer, sole trader or limited company with hundreds of employees.
• Then, “indemnity” means “protection against a loss or other financial burden.” In the context of professional indemnity insurance, this means your business is protected from the financial consequences of mistakes made while providing professional services.

In a nutshell, if a client claims your work or advice lost them money or caused reputational damage, PI insurance steps in.

What’s an example of a professional indemnity claim?

So, what might this look like in practice?

Let’s say you’re a freelance graphic designer. You’ve made an error in the text of a client’s marketing brochure. The mistake is only noticed after the materials are printed and sent out, leading to a poor customer response and a loss in sales for your client. They sue you for damages.

This is where professional indemnity insurance comes in. If you have PI insurance, it could cover the legal costs of defending the case and pay compensation if you’re found at fault. Without PI insurance, you’d be responsible for covering these costs.

What does professional indemnity insurance cover?

Professional indemnity insurance helps cover legal fees, settlements or compensation payouts if a client (or member of the public) files a claim against your business due to an error, omission or negligence in your professional service.

This could be anything from a “minor” incident (say, an important file is accidentally deleted) to large oversights causing lasting reputational or financial damage (for instance, if the guidance of a financial advisor leads to major losses).

Your professional indemnity policy could cover situations like:

• Professional mistakes or delays: If you make an error in your work, such as providing incorrect information or missing a deadline, causing a client financial or reputational loss.
• Negligence or breach of duty: If you fail to meet the standard of service expected in your profession, PI insurance can cover the associated costs. For example, if an architect’s plans result in structural issues costing the client money, this could be a breach of professional duty.
• Intellectual property: If you infringe on someone’s copyright or trademark, even unknowingly, PI insurance can cover the legal fees and damages.
• Defamation: If you unintentionally damage a client’s reputation (perhaps with incorrect claims in an email or a report), your PI insurance could cover the potential legal costs.
• Breach of confidentiality: If sensitive business information is shared without consent, even accidentally. For example, a consultant might unintentionally disclose data during a presentation.
• Errors in strategic advice: If professional advice or business activities lead to a costly mistake, PI insurance can help. For instance, a structural engineer’s incorrect calculations resulting in significant client losses.
• Data loss or mishandling: Losing critical documents or data can lead to claims. Imagine a solicitor leaves essential paperwork on a bus, or an IT contractor accidentally deletes important files. PI insurance could cover the resulting legal costs and any compensation.

What doesn’t professional indemnity insurance cover?

While we’re on the topic of coverage, it’s important to know that PI policies have a few common exclusions. This refers to situations that aren’t normally covered in your insurance policy.

For instance, PI insurance doesn’t cover scenarios where your company intentionally breaks the law. It also doesn’t cover things like personal injury claims or employee disputes.

Here’s a breakdown.

• Fraud or criminal acts: If you intentionally mislead clients or break the law, PI insurance won’t cover the consequences.
• Property damage or personal injury: Claims involving physical harm or damage to property fall under public liability insurance, not PI insurance.
• Cybersecurity breaches: Incidents like data breaches or hacking usually require a separate cyber liability insurance
• Employment disputes: Disagreements with employees or contractors (such as unfair dismissal or workplace grievances) are usually covered by employers’ liability insurance.
• Historical claims: Events or mistakes before you took out your PI insurance policy are excluded. PI insurance only covers incidents that happen after the start date of your policy. This is known as the “retroactive date”. So it's important to arrange cover as soon as your business begins operating.

What’s the purpose of professional indemnity insurance?

The main purpose of professional indemnity insurance is protecting your business from financial risk. A claim against you, whether justified or not, can rack up legal costs, damage your reputation and threaten the future of your business. Even if the claim is frivolous, you still have to pay for legal representation. And that can be expensive. This is where PI insurance acts as a safety net.

Here are some of the benefits professional indemnity insurance provides:

• Enhancing credibility: Having PI insurance demonstrates to clients that you’re serious, responsible and trustworthy. It shows you’re committed to protecting both their interests and your own.
• Winning contracts: A PI insurance policy can help you win business, especially if clients are large companies or government bodies that require insurance as a condition of hiring you.
• Peace of mind: Knowing you’re covered if something goes wrong helps you focus on delivering high-quality work. It means you aren’t constantly worrying about the potential financial fallout of mistakes.
• Long-term stability: PI insurance ensures that even if a costly claim arises, your business can recover and continue to grow. Without this support, a significant legal bill or compensation payout could jeopardise your long-term success.

Who needs professional indemnity insurance?

Given all the benefits of professional indemnity insurance, who’s it best suited for?

If you’re providing any kind of advice, services or expertise to clients (i.e. what’s known as “professional services”) PI insurance is sensible. It’s helpful for anyone from freelance copywriters to large multinational construction companies.

By having PI insurance, you’re not just protecting your business. You’re also giving clients confidence that risks are managed responsibly.

Here are some of the professions that benefit most.

• Consultants: When you’re providing business strategy, IT solutions or marketing advice, clients depend on your recommendations. If they believe your advice caused financial loss or setbacks, PI insurance can cover the costs of your legal defence and compensation claims.
• Creative professionals: Mistakes in creative work, like a missed deadline or a design error, can have real consequences for a client’s brand or campaign. PI insurance helps you manage the costs if a client claims their project was negatively affected.
• Financial and legal experts: These fields are high-stakes by nature. Whether it’s a small error in an accountant’s calculations or legal advice that leads to unexpected financial losses, PI insurance is there.
• Therapists and Counselors: Giving specialist advice comes with a lot of responsibility. If a client feels your guidance led to harm or was unhelpful, PI insurance ensures you’re protected.
• Architects and Engineers: Even a tiny miscalculation in a design or blueprint can have costly consequences, like structural issues or delays. PI insurance shields you from any claims of loss.
• IT professionals: Clients trust you with their critical systems and infrastructure. If your work causes unexpected downtime, security vulnerabilities or other issues, PI insurance covers the legal and reputational risks.

Do I legally need professional indemnity insurance?

For many professions, yes, you legally need professional indemnity insurance.

For example, if you’re an accountant, surveyor, solicitor, architect or financial advisor, having professional indemnity insurance is a legal requirement. Industry regulators and professional bodies like the Architects Registration Board (ARB) or the Financial Conduct Authority (FCA) insist on it to protect clients from professional negligence or mistakes.

For everyone else? It’s not always mandatory. But PI insurance is still important.

Even when it’s not a legal must-have, many client contracts (especially larger organisations or government bodies) expect you to have PI insurance before signing a contract. They’ll often specify a minimum level of cover, with figures like £1 million, £5 million or even £10 million depending on the work involved.

Do I need my own professional indemnity insurance?

Even if professional indemnity insurance isn’t a regulatory requirement, many business owners decide it’s still important.

If you’re a freelancer, contractor or sole trader, you need to arrange your own PI insurance. As an individual, you’ll need to choose adequate cover for your business to ensure you’re fully protected.

If you work for a larger company, they’ll probably have PI insurance. But don’t always assume it covers you personally. Let’s say you’re working as a structural consultant with a construction firm. In this case, it’s worth checking whether your employer’s cover extends to your work with clients. If not, you’ll need to ensure you’re covered on an individual level, too.

How much PI insurance do you need?

How much professional indemnity insurance you need depends on the size of your business, the industry you’re in, and the type of work you do. Every business is different, so there’s no universal answer. For small businesses or sole traders, you might only need £100,000 or £250,000 of cover. But for bigger companies or industries with higher risks (like law, surveying or finance), you could need £5 million or more.

Sometimes, your clients or industry bodies will tell you how much cover they expect. If they don’t, it’s worth asking before you take on any work—to get the right level of protection in place.

How much does professional indemnity insurance cost?

The cost of PI insurance varies based on several factors. It depends on your industry, the cover you need, the risks involved in your work and the size of your business. But in general, costs range from as little as £100 to £500 a year for small to medium-sized businesses. This can jump into the thousands for larger businesses working in high-risk industries.

Here are a few factors impacting the amount you pay.

• Claims history: If you’ve had previous claims, your premiums (i.e. the amount you pay each month) may be higher.
• Industry: High-risk industries (e.g., construction, IT or financial services) often face higher premiums due to the increased chance of large claims.
• Level of cover: The higher the amount of cover you need (e.g., £1m, £5m, etc.), the higher the premium.
• Business size: The larger your business and annual turnover, the more you’ll pay. Essentially, the more work you do and the more people you work with, the higher your risk of claims.
• Extra policies: You might opt for extra coverage like employers liability and public liability insurance. Your insurer may offer these as a package, reducing the overall cost.

It’s worth noting the cost of PI cover is a small price to pay for the protection it offers. The best way to find out how much it costs is a tailored professional indemnity insurance quote for your business.

In summary: Why is professional indemnity insurance important?

Whether or not it’s legally required for your profession, PI insurance is an essential safety net for anyone providing expert advice or services to clients. It shields you from the financial impact of legal claims and helps protect your business’s reputation.

Having PI insurance doesn’t just offer peace of mind. It also builds trust with your clients and shows you take your responsibilities seriously. If you’re working in a field where your work could cause financial or reputational harm to others, it’s definitely something to have in place.
