United Kingdom, 30 October 2026 — Questions surrounding professional liability and artificial intelligence are receiving attention across the UK insurance sector, following industry reporting published on 26 October about the legal uncertainties associated with AI systems and their use in financial services. The report by Insurance Business UK highlighted disclosures concerning potential liability for actions taken by AI systems and cited a joint survey by the Bank of England and the Financial Conduct Authority (FCA), which found that 86% of UK financial services firms were using AI. The developments have renewed interest in errors and omissions insurance, commonly known as E&O insurance, and its relationship with professional indemnity cover. For consultants, financial advisers, technology providers and other service businesses, the central issue is how existing insurance arrangements respond when professional advice, work or automated processes allegedly cause a client financial loss. The reporting does not establish that every AI-related claim is covered or excluded; the outcome depends on the facts, applicable law and the wording of the policy.
Professional Liability in a Changing Business Environment
Professional services depend on the accuracy, suitability and delivery of work agreed with clients. Accountants prepare financial information, consultants provide recommendations, technology companies develop digital systems, and advisers help clients interpret complex requirements. Errors, omissions, misunderstandings or failures to meet contractual obligations can sometimes lead to disputes and claims for financial compensation.
These circumstances form part of the context for professional indemnity insurance, the term commonly used in the United Kingdom for insurance addressing certain claims arising from professional services. E&O insurance is a closely related term used particularly in the United States and other markets. Although the expressions are often used to describe similar protection, their precise meaning and scope depend on the jurisdiction and individual contract.
According to, professional indemnity insurance can protect a business against claims alleging that its advice, work or services caused a client financial loss. The guidance identifies professional advisers and businesses whose industries or regulators require this type of cover as groups for whom it may be relevant.
The important distinction is that insurance responds according to the terms agreed with the insurer. A client complaint does not automatically establish professional negligence, and the existence of a policy does not mean every dispute will qualify for payment.
Artificial Intelligence Raises Questions About Responsibility
A report published by Insurance Business UK on 26 October 2026 examined liability questions associated with AI systems used across sectors including financial services, insurance and legal services. It discussed disclosures in Anthropic's prospectus concerning potential risks associated with its technology, alongside uncertainty about where legal responsibility might arise from actions taken by AI systems.
The report also referred to a joint survey published by the Bank of England and the FCA, stating that 86% of UK financial services firms were using AI and that the median insurer had 18 AI systems in production. These figures describe the findings reported by the publication; they should not be interpreted as evidence that all those systems operate autonomously or create the same level of risk.
The development is relevant to professional liability because businesses increasingly use automated tools to support research, document preparation, customer communications, data analysis and other operational tasks. The use of such systems can introduce questions about the accuracy of information, the adequacy of human review, contractual responsibilities and the handling of confidential material.
For example, a consultancy might use an AI tool to help prepare a report for a client. If the report contains an inaccurate figure, the business may need to investigate how the error arose, whether it was checked and whether the client suffered a financial loss. The circumstances would determine whether the issue involved professional negligence, a contractual dispute or another form of liability.
The example is illustrative rather than a report of an actual claim. It shows why businesses need to understand both their working procedures and the scope of their insurance arrangements.
What Errors and Omissions Insurance Covers
Errors and omissions insurance generally refers to cover designed to address specified claims alleging that a professional service caused financial harm through an error, omission or negligent act. Depending on the policy, covered circumstances may include inaccurate advice, mistakes in professional documents, failure to deliver an agreed service or other alleged shortcomings in work performed for a client.
The protection is not identical across all insurers or industries. A policy may define professional services narrowly, exclude certain activities or impose limits on the amount available for claims. Some contracts also contain specific provisions concerning intellectual property, confidentiality, cyber incidents, contractual liability or the use of particular technologies.
Businesses should therefore avoid assuming that an E&O policy covers every consequence of using software or AI. A claim involving incorrect professional advice may raise different questions from a claim involving stolen data, system interruption or unauthorised access to a computer network.
The relationship between these risks can be complicated. A technology-related incident might involve allegations about the quality of professional work and, at the same time, a separate failure in data security. Whether one policy, multiple policies or no policy responds will depend on the circumstances and contractual wording.
Professional indemnity cover should consequently be considered in the context of the actual services delivered, rather than solely on the basis of a product's name or headline coverage limit.
Understanding Policy Conditions and Exclusions
One of the practical tasks for any business purchasing insurance is to read the policy schedule, wording and exclusions. Business.gov.uk recommends checking what a policy covers, what it excludes, its financial limits and the conditions that policyholders must satisfy.
These details are relevant to professional liability because a policy may apply only to specified services, claims or circumstances. The definition of professional work, the territorial scope of the cover and the treatment of legal defence costs can affect how protection operates.
Another consideration is the basis on which the policy responds. Many professional indemnity policies are written on a claims-made basis. Broadly, this means that the timing of a claim or its notification, together with the policy's other conditions, can determine which insurance period is relevant. The date on which the original work was completed may not, by itself, establish which policy responds.
A retroactive date can also be significant because it may restrict cover to professional work undertaken on or after a specified date. Businesses changing insurers should review these terms carefully to understand how earlier work is treated.
The position may become particularly important during a merger, acquisition, business restructuring or closure. Previous professional work can give rise to a claim after the original service has been delivered. Appropriate arrangements for continuing or run-off cover may therefore need consideration.
These are general features of professional indemnity insurance, not a determination of any individual claim. Policyholders should seek clarification from their insurer or broker when a clause is unclear.
Reviewing AI Use and Professional Procedures
As AI becomes part of routine business activity, organisations can document where automated tools are used and what responsibilities remain with employees or contractors. This is a matter of operational governance as well as insurance administration.
A company might record which systems are approved, what types of information can be entered, who checks outputs and how significant errors are reported. It can also establish procedures for reviewing calculations, references, client documents and recommendations before they are delivered.
These steps do not guarantee that errors will be avoided. Their purpose is to make responsibilities and review procedures clearer, while providing an organised record of how professional work is prepared.
Businesses should also consider whether their insurance application accurately describes their activities. If the use of AI materially changes the services offered, the information provided to an insurer may need to be reviewed in accordance with the policy and applicable disclosure requirements.
For instance, a firm that previously provided manual research may begin delivering automated data analysis as part of its paid services. That change could affect the description of its professional activities, contractual commitments and risk profile. The firm should ask its broker or insurer whether the existing wording addresses the revised work.
It is also important to examine contracts with clients and technology suppliers. A service agreement may allocate responsibilities for checking information, handling confidential data or correcting defective work. Those contractual obligations do not necessarily match the scope of an insurance policy.
Clear documentation can help a business identify where responsibilities differ and where further clarification is needed.
Choosing Appropriate Professional Liability Protection
The amount and type of cover required depend on several factors, including the nature of the services, the size of the business, the clients served and the potential financial consequences of an allegation.
A small consultancy providing general business advice may have different requirements from an accountancy practice handling complex financial information or a technology company developing systems for regulated organisations. Contractual requirements and professional regulations may also affect the level of insurance a business must maintain.
Businesses can begin by reviewing their principal services and identifying the types of claims that could arise from their work. They should then compare policy definitions, exclusions, limits and conditions against those activities.
The premium is one consideration, but it should not be the sole basis for selecting cover. Two policies with similar headline limits may treat defence expenses, related claims, subcontracted work or particular professional activities differently.
It may be useful to ask an insurance broker to explain how a policy addresses the business's actual work, including any use of AI tools. Questions should be specific enough to establish whether the wording covers the intended services and what exclusions or limitations remain.
The provides a starting point for understanding the main categories of business insurance and the importance of reviewing policy documents. Industry-specific rules may impose additional requirements, so firms should also consult the relevant regulator or professional body.
Implications for UK Businesses
The developments reported in October 2026 illustrate a broader issue facing the insurance industry: businesses are adopting technologies while questions about accountability, contractual responsibility and insurability continue to evolve.
The reported use of AI across UK financial services does not establish that all firms face identical exposures. Risk depends on how a system is used, the information it processes, the level of human oversight and the consequences of an error. The same distinction applies to insurance: policy wording and the circumstances of a claim determine the available protection.
For businesses, the practical response is to align professional procedures, client contracts and insurance arrangements. Reviewing these areas can help identify gaps between the work a company undertakes and the activities described in its policy.
This process should include checking whether the business's services have changed, whether staff understand the relevant review procedures and whether any new technology introduces contractual or data-handling responsibilities. Existing insurance should be reviewed at renewal and when significant changes occur, in accordance with the applicable policy requirements.
Conclusion
The UK insurance sector's discussion of AI-related liability, highlighted in reporting published on 26 October 2026, provides a timely context for examining errors and omissions insurance. As professional services incorporate new technologies, businesses need to understand how responsibility for mistakes is allocated and how insurance policies define the work they cover.
Professional indemnity insurance and E&O cover can address specified claims arising from professional services, but neither term represents an unconditional guarantee against financial loss. Exclusions, notification requirements, limits and the definition of insured activities all influence the scope of protection.
For companies using AI or other digital tools, regular reviews of contracts, internal procedures and insurance wording can help clarify responsibilities and identify questions that need to be addressed. Decisions about cover should be based on the business's actual circumstances and the terms offered by the insurer.
The wider issue is not simply whether a company holds insurance, but whether the policy corresponds with its professional activities and the risks it intends to manage.
