Defamation Against a Company UK: Corporate Claimants and the Serious Harm Test

Companies can bring defamation claims in the UK, but they face a significantly higher legal threshold than individual claimants. The Defamation Act 2013 introduced a specific test for corporate claimants that has reduced the volume of business defamation claims — but companies with strong evidence of financial harm retain a powerful legal remedy.

Can a Company Sue for Defamation?

Yes. Companies, partnerships, and other trading entities can bring defamation claims in England and Wales. However, the 2013 Act treats corporate claimants differently from individuals, reflecting a policy decision to prevent well-resourced companies from using defamation claims to suppress legitimate criticism.

The key statutory provision is section 1(2) of the Defamation Act 2013, which provides that a body that trades for profit can only satisfy the serious harm test if the publication has caused, or is likely to cause, the body serious financial loss. This is distinct from the test for individuals, who must show serious harm to reputation (which may include non-financial harm such as social consequences).

The Serious Financial Loss Test

Serious financial loss is a higher threshold than serious reputational harm. A company cannot simply point to the gravity of the allegation or the extent of publication — it must show concrete, measurable financial consequences. Evidence that courts have accepted as demonstrating serious financial loss includes:

• Evidence of specific lost contracts or cancelled orders caused by the publication
• Evidence of reduced revenues or profit margins in the period following publication
• Evidence of lost investment or declined financing linked to the defamatory content
• Evidence of customer or client cancellations with documents linking them to the publication
• Expert evidence from an accountant or economist quantifying the financial impact

The Supreme Court in Lachaux v Independent Print Ltd [2019] confirmed that actual consequences — not merely inherent probabilities — must be demonstrated. For companies, this requirement has real teeth: courts will scrutinise causation carefully, distinguishing losses caused by the publication from losses caused by other trading factors.

What Counts as Publication Against a Company?

The same rules of publication apply to companies as to individuals. Publication occurs when a defamatory statement is communicated to at least one person other than the company. For corporate claimants, common publications include:

• False Google, Trustpilot, or sector-specific reviews
• Defamatory posts on social media platforms targeting the business
• False allegations in trade press or industry forums
• Competitor smear campaigns disseminated to mutual clients or suppliers
• Defamatory statements in regulatory complaints or correspondence widely circulated
• False allegations by former employees or disgruntled customers online

Defences Available to Defendants in Corporate Claims

The defences available under the Defamation Act 2013 apply equally in corporate defamation cases. Courts tend to give particular weight to the honest opinion and public interest defences where the target is a company:

• Truth (s.2): The defendant may prove the substance of the allegation is true. This is a complete defence.
• Honest opinion (s.3): Comment on a company's products, services, or business conduct may qualify as honest opinion where it is genuinely the reviewer's view, expressed as opinion rather than fact.
• Public interest (s.4): Investigative journalism, regulatory disclosure, or whistleblowing about corporate misconduct may attract the public interest defence.
• Consumer review platforms: Under the Online Safety Act 2023, platforms hosting consumer reviews will have enhanced obligations but also new defences relating to compliance with their systems.

The Derbyshire Principle: Public Authorities Cannot Sue

An important exception in corporate defamation law is the Derbyshire County Council v Times Newspapers [1993] AC 534 principle. Public authorities and governmental bodies — including local councils, government departments, and public corporations — cannot bring defamation claims. The rationale is that allowing governmental bodies to silence their critics through defamation litigation would unacceptably chill free speech about the exercise of public power.

This principle applies to the body itself, not to individual employees or officials. A named council officer whose personal reputation has been attacked can still bring an individual claim.

Malicious Falsehood: An Alternative or Additional Claim

Where a company cannot establish serious financial loss for a defamation claim, or where the statement is arguably true but misleadingly presented, the tort of malicious falsehood (also known as trade libel or injurious falsehood) may provide an alternative remedy. To succeed in malicious falsehood, the company must prove:

1. The statement was false
2. The defendant published it maliciously (knowing it was false or being recklessly indifferent)
3. The statement caused or was likely to cause financial damage

Unlike defamation, malicious falsehood requires proof of malice — making it harder to establish — but it does not require the claimant to demonstrate "serious" harm in the same way. It is commonly pleaded alongside defamation in corporate cases.

Strategy for Corporate Defamation Claims

Companies considering a defamation claim should approach it strategically, balancing the potential benefits of vindication and compensation against the costs, duration, and publicity risks of litigation. Key strategic considerations include:

• Evidence of financial harm: Gather evidence of financial impact from the outset, including records of lost opportunities causally linked to the publication.
• Reputation management alongside legal action: Defamation litigation can itself generate publicity that amplifies the original allegation. A combined legal and communications strategy is often more effective.
• Pre-action correspondence: Many corporate defamation disputes are resolved through a properly drafted pre-action letter demanding removal and retraction, avoiding the costs and publicity of full proceedings.
• Proportionality: Courts and commentators are alert to companies using defamation claims to suppress consumer criticism. Pursuing only cases where genuine, substantial harm can be demonstrated is both legally advisable and reputationally sound.

Conclusion

Companies can and do succeed in defamation claims in the UK, but the serious financial loss test imposes a meaningful evidentiary burden that distinguishes corporate from individual claims. With strong evidence of financial harm and specialist legal advice, defamation litigation remains a valuable tool for protecting business reputation.
