What is professional liability insurance?

For accountancy and legal professionals, or other types of advisory business, professional liability insurance (PLI for short) can be a key protection. It’s designed to protect you if a customer suffers a financial loss, and holds you responsible. Clients and professional bodies often require a minimum level of professional liability insurance coverage – we offer between £50,000 and £5 million, depending on the individual business.

Professional liability insurance is also known as professional indemnity insurance. They’re the same cover, designed to protect professionals against PI claims.

  • professional liability insurance coverage between £50,000 and £5 million
  • get it as a standalone cover or add it to a broader business insurance policy
  • add tools, accident, and employee cover – you choose what you need

Professional liabilities insurance – what’s covered?

If you’re running an advisory business, professional liability insurance can cover your legal and compensation costs if a customer makes a financial loss because of your work. From negligence claims and mistakes to copyright infringement and breaches of confidentiality, professional liabilities insurance is built to cover a range of risks.

What’s covered?

  • Claims for advice, design or certification errors, or libel, which lead to a financial loss for a third party.

For example:

  • as a marketing consultant, you advise a client to increase their spend in a specific area, to attract more customers. The campaign is unsuccessful, however, leading to a proven loss

What isn’t covered?

  • data breaches
  • third party injuries or damage – public liability insurance is designed to cover this
  • fines and penalties (including non-compensatory damages)
  • dishonest and malicious acts
  • services carried out or circumstances you were aware of before your professional liability insurance policy start date (also known as ‘retroactive’) aren’t covered as standard but may be available with some insurers
