Quick Answer: What Is Professional Indemnity Insurance?
Professional indemnity insurance (PI insurance) is a type of business insurance that protects UK professionals and service businesses from financial loss if a client claims their advice, work, or professional services caused a financial or reputational loss. It covers legal defence costs and any resulting compensation payments. In the UK, PI insurance is legally or regulatorily required for solicitors, architects, financial advisers (IFAs), accountants in certain roles, and other regulated professions. For many more professionals it is contractually required by clients even when not mandated by law.

•How Artemis Insurance Brokers can help
If your business gives advice, provides professional services, or produces work that clients act on and rely on, there is one insurance question you cannot afford to get wrong: do you have professional indemnity cover in place?
Professional indemnity insurance is one of the most important types of business insurance for UK professionals. It is also one of the most misunderstood. Many business owners are uncertain whether they actually need it, what it does and does not cover, and how to choose a policy that genuinely protects them when a claim arrives.
This guide covers all of it. We have been arranging professional indemnity insurance for UK businesses across every major professional sector for over 30 years at Artemis Insurance Brokers. We work with solicitors, accountants, architects, consultants, marketing agencies, technology companies, IFAs, and many more. What follows is the practical, honest guide we give to our clients every day, with no jargon and no sales spin.
What Is Professional Indemnity Insurance and How Does It Work?
Professional indemnity insurance protects you if a client makes a claim against your business because of a mistake, an error of judgement, or negligent advice that caused them a financial loss. It can cover both the cost of defending yourself against the claim and any compensation you are ultimately required to pay.
The key word here is 'alleged'. A client does not have to prove you were actually negligent for a PI claim to be made against you. The claim can arise simply from a client's belief that your advice or work was inadequate, even if you are entirely confident it was not. Defending that allegation, whether it has merit or not, costs money, and that is where PI insurance steps in.
A Practical Example
A marketing consultant delivers a campaign strategy for a client. The campaign underperforms and the client's revenue falls short of their targets. The client claims the consultant's strategy was flawed and seeks compensation for the shortfall. The consultant believes their work met all agreed specifications. Regardless of who is right, the consultant now faces a legal dispute. Without professional indemnity insurance, the cost of defending that case, whether they win or lose, is entirely their own.
With PI insurance in place, the insurer covers the legal defence costs from the outset and any damages awarded if the case goes against them. That protection is what professional indemnity insurance exists to provide.
Key Point: PI insurance covers claims that arise from the professional services you provide. It is distinct from public liability insurance, which covers claims from third parties injured or having property damaged by your business activities.
What Does Professional Indemnity Insurance Cover?
A standard professional indemnity insurance policy in the UK will typically cover the following types of claim.
Professional Negligence
This is the most common type of PI claim. A client alleges that your professional advice or services fell below the standard of care expected, and that this failure caused them financial loss. Cover can include both the cost of legal defence and any damages awarded.
Errors and Omissions
Sometimes referred to as E&O insurance, this covers claims arising from mistakes in your work, deliverables, or professional output. A software developer ships code with a critical bug. An accountant files incorrect tax returns. A solicitor misses a filing deadline. Each of these scenarios represents an error or omission that can give rise to a PI claim.
Breach of Confidentiality
If your business inadvertently discloses confidential client information, for example by sending a document to the wrong recipient or failing to secure sensitive data appropriately, a PI policy will typically cover the resulting claim. Note that intentional disclosure is excluded.
Defamation and Libel
If your professional communications, published content, or advice contains statements that a third party considers defamatory, PI insurance can cover the defence costs and any resulting damages.
Intellectual Property Infringement
If your professional work inadvertently infringes a third party's copyright, trade mark, or other intellectual property rights, PI insurance can cover the claim. This is a growing area of risk for designers, copywriters, marketing agencies, and software developers.
Loss of Documents or Data
If client documents, data, or records in your care are lost, damaged, or destroyed, PI insurance covers the resulting claim. This is particularly relevant for legal, accounting, and financial services businesses that hold significant volumes of sensitive client records.
What Is Not Covered?
Important: PI insurance does not cover intentional wrongdoing, fraud, or criminal acts. It does not cover claims arising from work that was explicitly outside the agreed scope of your services. It does not cover personal injury or property damage claims, which fall under public liability insurance. It does not cover employment disputes with your own staff, which is the territory of employers liability insurance. Always read your policy exclusions carefully.
Who Is Legally Required to Have Professional Indemnity Insurance in the UK?
Several UK professions are required to hold professional indemnity insurance as a condition of their regulatory authorisation or professional body membership. Operating without it in these cases is not just financially risky. It is legally or professionally impermissible.
Profession | Regulatory Body | PI Requirement |
Solicitors Regulation Authority (SRA) | Mandatory minimum limits apply. Must hold SRA-approved PI policy. | |
Architects Registration Board (ARB) | Required for registration and practice. | |
Financial Conduct Authority (FCA) | Required for FCA authorisation. Minimum limits set by FCA. | |
Accountants (ICAEW members) | Institute of Chartered Accountants in England and Wales | Required for practising certificate. |
Royal Institution of Chartered Surveyors (RICS) | Required for RICS membership and practice. | |
Various licensing bodies | Required as a condition of licence. | |
Intellectual Property Regulation Board (IPReg) | Required for registration. | |
Healthcare Professionals (private) | Various bodies including GMC, NMC | Strongly advised; required by most professional bodies. |
Note for Solicitors: The SRA sets minimum indemnity limits and requires policies to be taken out with SRA-approved insurers only. Artemis Insurance Brokers has direct access to leading Law Society-panel insurers and can arrange SRA-compliant PI cover for solicitors of all sizes.
Who Else Should Strongly Consider PI Insurance?
Beyond the regulated professions above, there is a very broad range of UK businesses and self-employed professionals for whom PI insurance is strongly advisable, even when not legally required. If any of the following apply to your business, you should be considering PI cover.
•You provide advice, recommendations, or professional opinions that clients rely on to make decisions
•You produce designs, plans, specifications, documents, or reports that form the basis of your client's actions
•Your contracts with clients include performance obligations or professional standards requirements
•Your clients are larger organisations that require proof of PI insurance before awarding work
•You work in the public sector or on government contracts, where PI insurance is almost universally required
•You handle sensitive client information, financial data, or intellectual property
•You provide IT, technology, or software development services
•You work as a contractor through an agency or umbrella company
The list of professions for whom PI insurance is commercially essential, even without a regulatory mandate, includes management consultants, marketing and communications agencies, PR firms, HR consultants, business coaches, software developers, IT consultants, project managers, training providers, healthcare consultants, and many more.
How Much Does Professional Indemnity Insurance Cost in the UK?
Cost is one of the first practical questions professionals ask when researching PI insurance, and it deserves a straight answer. The honest truth is that there is no meaningful figure we can give you without understanding your business, because the variables that drive PI premiums are significant and they interact in ways that make any generic number misleading.
What we can tell you is exactly what those variables are, because understanding what drives your premium is the most useful starting point before you speak to a broker or insurer.
The main factors that affect the cost of professional indemnity insurance in the UK are your profession and the specific nature of the work you carry out, your annual fee income or turnover, the indemnity limit you need, whether your regulatory body sets a minimum that you cannot go below, your claims history over the previous five years, the size of individual contracts or projects you take on, and whether your clients are large organisations with contractual minimum requirements built into their supplier agreements.
A sole trader consultant in a lower-risk advisory field will pay considerably less than a technology company handling sensitive client data on high-value contracts. A solicitor in a high-volume conveyancing practice operates in one of the most heavily loaded PI risk categories in the UK market. An architect working on large commercial projects faces fundamentally different exposure to one producing domestic planning applications. The same profession can carry very different premiums depending on the specific risk profile of the individual business.
Selecting the lowest available premium without understanding the quality of the cover behind it is one of the most common and costly mistakes professionals make with PI insurance. A policy with a high excess, restrictive exclusions, or poor claims handling can leave you significantly exposed at exactly the moment you need your insurer to perform.
The most accurate and reliable way to understand what PI insurance will cost for your specific business is to speak with an independent broker who has direct access to a wide panel of specialist PI insurers and understands the underwriting criteria each one applies to your profession.

What Factors Affect the Cost of PI Insurance?
•Your profession and the nature of the work you do
•Your annual fee income or turnover
•The indemnity limit you require, for example £500,000 versus £5,000,000
•Your excess, which is the amount you contribute to each claim before the insurer pays
•Your claims history over the previous five years
•The size of individual contracts or projects you undertake
•Whether your clients include public sector bodies or large organisations with higher risk profiles
•Whether your work has an international element, as some policies exclude non-UK work
How to Choose the Right Level of PI Cover
Choosing the right indemnity limit is one of the most important decisions you will make when taking out a PI policy. Too low and you risk being underinsured when a significant claim is made .
The starting point is your regulatory requirement, if you have one. Solicitors must comply with SRA minimum limits. IFAs must meet FCA requirements. For professions with no regulatory floor, consider the following questions.
1.What is the maximum fee value of any single contract or project you undertake? Your indemnity limit should typically be a multiple of this, not equal to it, because legal costs alone can easily exceed the value of the contract in dispute.
2.What do your clients contractually require? Check your standard client contracts and any frameworks or approved supplier lists you are registered on. Many specify minimum PI limits of £2 million, £3 million, or higher.
3.What is the highest-risk piece of advice or work you provide? Think about the downstream consequences if that advice is wrong. The potential financial impact on your client should inform your indemnity limit.
4.What level of excess can you comfortably absorb? A higher excess reduces your premium but means you pay more of each claim yourself. Make sure the excess is genuinely affordable without causing financial strain.
Artemis Advice: We always recommend erring on the side of a higher indemnity limit rather than a lower one. The additional annual premium for moving from £500,000 to £1,000,000 of cover is often a few hundred pounds at most. The difference in protection it provides can be the difference between a business surviving a claim and one that does not.
Claims Made Versus Occurrence-Based PI Policies
This is one of the most important technical distinctions in professional indemnity insurance, and one that many business owners overlook when comparing policies.
Claims Made Policies
The vast majority of PI insurance policies in the UK are written on a claims made basis. This means the policy that responds to a claim is the policy that is in force at the time the claim is made against you, not at the time the work was originally carried out. If a client makes a claim against you in 2026 for work you did in 2023, your 2026 policy responds.
This has an important practical consequence: your PI cover must be continuous. If you allow your policy to lapse, you lose protection for past work as well as current work. This is why it is critical to renew every year without a break, and why run-off cover (covered below) matters so much when you stop practising.
Occurrence-Based Policies
Occurrence-based PI policies are less common in the UK market. With an occurrence policy, the policy that responds to a claim is the one that was in force at the time the work was done, regardless of when the claim is actually made. These policies can provide cover even after they have expired.
Run-Off Cover: What It Is and Why It Matters
Run-off cover is an extension to your professional indemnity insurance that continues to protect you from claims arising from past work after you have stopped trading, retired, or closed your business. Because PI policies are typically written on a claims made basis, simply letting your policy lapse when you close your business does not mean you are protected from future claims about past work. A client could bring a claim years after you have ceased trading.
Run-off cover is particularly important for solicitors, accountants, architects, and any professional who has carried significant responsibility over a long period. In regulated professions, run-off requirements are often stipulated by the professional body. The SRA, for example, requires solicitors' practices to maintain run-off cover for a minimum of six years following closure.
The cost of run-off cover varies depending on your profession, the level of cover, and the period for which it is required. Your broker should discuss run-off provisions at or before the point of any planned business closure or change in structure.
Professional Indemnity Insurance by Profession
Solicitors
Professional indemnity insurance for solicitors in the UK is mandatory under the SRA's Indemnity Insurance Rules. All solicitor practices must hold PI cover with an SRA-approved insurer. The minimum indemnity limit is £3 million for incorporated practices and £2 million for unincorporated practices.
Artemis Insurance Brokers has relationships with leading Law Society-panel insurers and has been arranging solicitors PI insurance for over 20 years. We can access the specialist market for high-risk practice areas including conveyancing, litigation, and immigration law.
Accountants
Professional indemnity insurance for accountants is required for practising certificate holders with ICAEW, ACCA, CIMA, and most other accountancy bodies. The required cover level varies by body and by the size and type of the practice. Accountants carrying out audit work, insolvency, or investment business typically face higher premium levels due to the elevated risk profile of those activities.
Architects
Architects registered with the ARB must hold adequate PI insurance as a condition of their registration. The ARB does not set a specific minimum indemnity limit but expects cover to be proportionate to the nature and scale of work undertaken.
Independent Financial Advisers and IFAs
PI insurance for IFAs and financial advisers is required by the FCA as a condition of their authorisation. The FCA sets minimum indemnity requirements through the FCA Handbook (IPRU-INV rules). The required level of cover depends on the IFA's income and business type.
Consultants and Business Advisers
Management consultants, business coaches, HR consultants, training providers, and similar advisory professionals sit outside the regulated professions framework in most cases, but they face very real PI exposure from the advice they provide. A management consultant who recommends a business restructure that leads to significant losses, or an HR consultant whose advice results in an employment tribunal, can face claims that easily exceed the value of their original engagement. Cover starting at £250,000 is usually advisable, rising to £1 million or more for those working with larger organisations.
Technology and IT Companies
PI insurance for technology businesses covers errors in software, systems design, data management, and technical advice. With the UK cyber security and tech sector growing rapidly, this is an area where claims are increasingly common. Technology PI policies often include elements of cyber liability cover, or the two can be arranged as a combined package. Indemnity limits of £1 million to £5+ million are common for established technology businesses.
Common Mistakes UK Professionals Make with PI Insurance
Taking the Cheapest Policy Available
PI insurance is not a commodity. The cheapest policy is rarely the best value. Wide variations exist between policies in terms of what is and is not covered, how claims are handled, and how cooperative the insurer is when you actually need to make a claim. Focus on the quality of the cover and the reputation of the insurer, not just the premium.
Underestimating the Level of Cover Required
Many professionals underestimate their indemnity limit because it seems adequate for their typical project values. But a significant PI claim, particularly one involving lengthy litigation, can generate legal costs alone that run into hundreds of thousands of pounds before any damages are considered. The right indemnity level should reflect your worst-case risk exposure, not your average contract value.
Not Disclosing All Material Information
UK insurance law (the Insurance Act 2015) requires you to make a fair presentation of your risk to your insurer. This means disclosing all material facts, including your full claims history, the full range of services you provide, and any circumstances that could give rise to a claim that you are already aware of at the time of application. Failing to do so can result in your insurer declining to pay a claim or voiding your policy entirely.
Allowing the Policy to Lapse
Because PI policies are typically claims made, allowing your policy to lapse even for a brief period can leave you without cover for past work during the gap period. Always renew before your existing policy expires, and if you are changing insurers, ensure there is no gap between the end of the old policy and the start of the new one.
Forgetting About Run-Off Cover When Closing
Business owners who close their company, retire, or restructure often overlook the need for run-off cover. A claim can arrive years after the work was completed. Without run-off cover in place, there is no PI policy to respond to it.
Frequently Asked Questions About Professional Indemnity Insurance
What is professional indemnity insurance in simple terms?
Professional indemnity insurance protects you financially if a client makes a claim against you because they believe your advice, your work, or your professional services caused them a financial loss. It can cover for the cost of defending the claim, including legal fees, and covers any compensation or damages you are required to pay if the claim succeeds. It is sometimes also called PI insurance or errors and omissions (E&O) insurance.
Who needs professional indemnity insurance in the UK?
Professional indemnity insurance is legally or regulatorily required for solicitors (SRA rules), architects (ARB requirement), financial advisers and IFAs (FCA requirement), and chartered accountants in certain roles (ICAEW and other body requirements). Beyond the regulated professions, it is essential for any business or self-employed professional who provides advice, professional services, or work products that clients rely on. This includes consultants, IT companies, marketing agencies, engineers, healthcare professionals in private practice, and many others.
What is the difference between professional indemnity and public liability?
Professional indemnity insurance covers claims arising from your professional services, advice, or work. It responds when a client claims your professional activities caused them a financial loss. Public liability insurance covers claims from members of the public or third parties who suffer physical injury or property damage as a result of your business activities. A consultant working from a client's office would typically need both: PI insurance for any claims arising from their advice, and public liability in case they accidentally damage the client's property.
What does run-off cover mean for PI insurance?
Run-off cover is an extension to your PI insurance that continues to protect you from claims about past work after your current policy has expired or after you have stopped trading. Because most PI policies in the UK are written on a claims made basis, the policy in force when the claim is made is the one that responds. If you have no policy in force when a claim arrives, there is no cover. Run-off cover fills that gap for a defined period after you cease practising.
How long does a professional indemnity claim take to resolve in the UK?
The timeline for a PI claim in the UK varies significantly depending on the complexity of the case, whether it settles out of court or proceeds to litigation, and the cooperation of all parties involved. Simple claims that settle quickly can be resolved within a few months. Complex claims involving multiple parties or technical disputes can take longer to fully resolve. Your insurer appoints legal representatives to manage the defence of the claim throughout the process.
Can I get professional indemnity insurance with a claims history?
Yes, it is possible to obtain PI insurance with a previous claims history, though your premium is likely to be higher and the choice of insurers may be more limited. Full disclosure of all past claims is required when applying for cover. Working with a specialist independent broker who understands the PI market is particularly valuable if you have a claims history, as they can identify insurers who will look favourably on your specific situation and negotiate the best available terms.
