Professional indemnity insurance is designed to protect businesses that provide services or expert advice. It covers the costs of defending a claim and any damages if a client alleges they’ve suffered financial loss due to your actions or advice. This could include situations like a design error, a breach of confidentiality, or unintentionally harming a client’s reputation.

Even if your services are provided for free, a client can still bring a claim against you, making professional indemnity insurance a vital safeguard. In fact, over a quarter of insurance claims made in the UK are related to professional indemnity, highlighting just how common these disputes are.

While professional indemnity insurance is not legally required for all businesses, it is often mandatory for certain industries or trade bodies. Additionally, many clients — especially larger corporations — may request proof of cover before working with you.

Despite its importance, a 2026 Association of British Insurers report found that 64% of SMEs don’t have professional indemnity insurance, and are potentially exposing themselves to significant financial risk by not having it. 

Professional indemnity insurance isn’t legally required in the UK, but it’s strongly recommended for any business that offers advice or handles sensitive client information. If a mistake leads to financial loss or a data breach, you could face costly legal claims.

While any business providing professional services could benefit from this type of cover, it’s likely to be particularly valuable for: 

• Financial advisors: Protects against claims related to any financial advice that results in client losses. 

• Architects: Covers any errors in design, planning, or construction that cause property damage. 

• Accountants: Provides protection against claims resulting from mistakes in financial advice and/or reporting. 

• Advertising agencies: Safeguards against issues related to misleading campaigns and/or intellectual property disputes. 

• Graphic designers: Helps protect against design errors and/or copyright infringement claims.

• Solicitors and lawyers: Essential to cover legal advice and the risk of errors that could harm clients.

While professional indemnity insurance is not always a legal requirement, it can be essential for protecting both your business’ reputation and finances. For some industries, however, professional indemnity insurance is mandatory to operate legally.

Some professions even require it as part of regulatory and licensing rules. For instance, solicitors need to hold professional indemnity insurance as a regulatory condition set by the Solicitors Regulation Authority (SRA). 

Why is it worth having?

Even if professional indemnity insurance isn’t a requirement for your profession, securing this coverage can be crucial for protecting your business from potential risks. Without it, your business could face significant financial consequences if a client claims they’ve suffered a loss due to your services. 

Professional indemnity insurance can act as a safety net that helps mitigate risk. For self-employed professionals, small business owners and start-ups, having professional indemnity insurance can be essential, offering both financial protection and peace of mind, an important safety net if you have just become self employed. 

The cost of professional indemnity insurance in the UK varies based on several factors, including the size and type of your business. Insurers will assess your annual turnover, industry sector, claims history, and the level of cover you need. 

To find the right policy at the best value, choose an insurer that lets you tailor your coverage to match your specific business risks. By customising your professional indemnity insurance, you can ensure you’re neither over-insured nor under-protected.
