Professional Indemnity Insurance: Who Needs it and Why it Matters

Professional Indemnity Insurance (PII) is a crucial safeguard for any business or sole trader who provides advice, design work, consultancy, or professional services. It protects against claims of negligence, errors, omissions, or breaches of professional duty that lead to a client’s financial loss.

While many people assume this cover is only for traditional “professional” industries, the reality is that a wide range of businesses—often without realising it—carry professional liability risk every day. Here, we cover the types of professions that are often unaware they need this type of insurance (e.g., tradespersons), how it works, and the value of continuity of cover.

Who Typically Needs Professional Indemnity Insurance?

PII is commonly associated with professions where expert advice or design work is central to the service provided. This includes:

• Architects

• Consultants

• Marketing Agencies

• Engineers

• Designers

• Surveyors

  
  

These businesses often work on projects where mistakes can lead to costly consequences. Professional indemnity cover ensures that if something goes wrong, the financial fallout doesn’t fall solely on the business.

Industries That May Not Realise They Need It

Many tradespeople don’t realise they also undertake 'professional work'—meaning they may be exposed to risks that PII is specifically designed to cover.

This includes:

• Builders

• Plumbers

• Electricians

  
  

Even when not formally “designing,” these jobs often involve design decisions as part of day‑to‑day tasks. Examples include:

-An electrician choosing socket placement, cable routes, or cabling type is making design choices on behalf of the client.

-Contractors may amend architect plans during installation when real‑world conditions differ from drawings.

-Builders may design and construct outbuildings, extensions, or even full properties.

Where design judgment is involved, the risk of error follows, making PII a valuable protection for any trade.

Understanding Claims-Made Basis: How Professional Indemnity Works

Professional indemnity policies operate on a claims‑made basis, which is different from general liability insurance.

To trigger cover, two conditions must be met:

1. The policy must have been active at the time the error or omission occurred.

2. The policy must also be active when the error is discovered and the claim is made.

This is why continuity of cover is essential.

What Is a Retroactive Date?

Most policies include a retroactive date, often the date the business first started. This allows the policy to cover past work—provided there have been no gaps in insurance.

Regulatory Requirements

In many professions, maintaining professional indemnity insurance is a regulatory requirement. Failure to comply can result in loss of accreditation or regulated status, which can significantly hinder a business’s ability to operate.

Regulatory bodies that commonly require PII include:

• ACCA (Association of Chartered Certified Accountants)

• RICS (Royal Institution of Chartered Surveyors)

• SRA (Solicitors Regulation Authority)

• FCA (Financial Conduct Authority)

Run‑Off Cover: Protection After You Stop Trading

Even after retirement, ceasing to trade, selling, or closing a business, the risk of a claim remains. Because PII is claims‑made, you must maintain run‑off cover to protect against claims relating to past work.

Run‑off cover typically lasts six years, aligning with the standard statute of limitations for negligence claims. Without it, any claim made after the policy ends would not be covered by insurers—regardless of when the work was carried out.
