Defamation at Business Networking Events: Can Spoken Words at a Conference Cost You?

Professional slander — false allegations made about a person or business at a conference, networking dinner, or industry event — is a significant and underserved area of UK defamation law. Unlike online defamation, it leaves no automatic digital trace, making early action to preserve evidence critical.

Slander at Professional Events: The Legal Framework

Slander — spoken defamation — is governed by the same Defamation Act 2013 framework as libel. The serious harm test applies equally to spoken and written statements. For a business, statements that disparage professional competence or integrity at an industry event — heard by potential clients, partners, or employers — can cause substantial harm that readily meets the threshold.

The Evidential Challenge

The practical difficulty with conference slander is proof. Written defamation can be screenshotted and archived. Spoken words depend on the recollection of those who heard them. However, many sessions at conferences and professional events are now recorded — video and audio recordings can provide direct and compelling evidence. Where multiple attendees heard the same statement, contemporaneous witness accounts taken promptly after the event are highly valuable.

When Does Qualified Privilege Apply?

Statements made at professional events do not automatically attract qualified privilege. Privilege applies where there is a recognised duty to communicate and a corresponding interest in receiving the information — for example, a reference given in response to a direct inquiry. Casual allegations made in networking conversations are not privileged, even in a professional context.

Special Damage and Business Disparagement

Most slander claims require proof of actual financial loss (special damage). However, words that disparage a person in their trade, business, calling, or profession are actionable per se — without needing to prove specific financial loss. Statements at a business event alleging professional misconduct, incompetence, or dishonesty almost invariably fall within this category.

Immediate Steps After a Slander at a Professional Event

• Make a written note immediately after the event — record the exact words used, the context, the speaker, and every person present who heard it.
• Obtain contact details of witnesses before leaving the event.
• Do not confront the speaker publicly — this risks creating a counter-narrative and complicating any subsequent proceedings.
• Instruct a specialist defamation solicitor promptly to preserve witness evidence and advise on next steps.
