Can You Sue Someone For Slander In The UK?

If someone is spreading damaging rumours about your business, it can feel urgent to “sue for slander” and set the record straight.

In the UK, you can take legal action over damaging statements - but there are important rules about what counts as slander, when a company can sue, the proof you’ll need, and the steps to take before starting court proceedings.

In this guide, we’ll unpack what “slander” means under UK law, how the serious harm test works for businesses, practical steps to stop the damage quickly, and when it’s realistic to sue.

What Counts As Slander Under UK Law?

UK defamation law covers two types of wrongful statements:

• Libel - written or otherwise recorded/published (for example, a Google review, blog post, email or social media post)
• Slander - spoken and transient (for example, false statements said in a meeting, on a call or at an event)

Both are forms of defamation. The Defamation Act 2013 sets the modern rules, including a key threshold: the statement must have caused, or be likely to cause, “serious harm” to the claimant’s reputation.

For companies trading for profit, “serious harm” means serious financial loss. In short, a business must show the slander has caused, or is likely to cause, real financial damage (for example, lost sales, cancelled contracts or measurable reputational loss that translates to money).

A few other essentials:

• Who can sue? Trading companies and partnerships can sue. Public bodies (like local authorities) can’t. Individuals (including directors) can sue in their own right if they’ve personally been defamed.
• Who can be liable? The person who made the statement is the primary target. Under the Defamation Act, it’s generally harder to sue secondary parties (like event hosts or platforms) unless it’s not reasonably practicable to sue the primary publisher.
• Time limit: Defamation claims usually must be issued within 1 year of publication. That’s a short window - act quickly.
• Evidence matters: Slander is transient, so you’ll need reliable evidence of what was said, when, and to whom - particularly to prove serious financial loss.

One historical difference to note: at common law, slander typically required proof of “special damage” (actual loss) unless it fell into narrow categories (such as allegations of criminality or professional incompetence). Today, the serious harm test under the Defamation Act 2013 is the central question - and for businesses, that means serious financial loss.

Can A UK Business Sue For Slander?

Yes - if your business can show a false, damaging spoken statement has caused (or is likely to cause) serious financial loss.

However, defamation claims are technical and costly. Before launching a lawsuit, it’s crucial to weigh up:

• Evidence: Do you have witnesses, contemporaneous notes, audio or other reliable proof of what was said? If you lawfully record conversations in the UK (for example, in a meeting on your premises with appropriate notices), that can help - but always consider privacy and data protection rules.
• Serious financial loss: Can you link the slander to concrete losses (e.g. a contract cancellation, measurable drop in revenue tied to the statement)?
• Defences: Might the other side argue truth, honest opinion, public interest or privilege? (We cover these below.)
• Practical alternatives: Could you achieve a quicker and cheaper outcome via takedown requests, corrections, retractions, mediation or settlement?

If your facts don’t meet the defamation threshold, you might still have other claims - such as “malicious falsehood” (false statements causing financial loss that aren’t necessarily defamatory), breach of contract, or harassment. The right route depends on your evidence and goals, so tailored advice is wise.

Before You Sue: Practical Steps To Stop The Damage

In many cases, you can limit or undo the reputational damage without issuing a claim. A sensible early response often preserves relationships and reduces cost, all while strengthening your legal position if you do need to sue.

1) Secure Your Evidence

• Write down exactly what was said, by whom, when, where, and in front of which third parties.
• Collect corroboration: witness statements, calendar entries, emails, and any immediate reactions (for example, a client email referencing what they heard).
• Be careful if you plan to record calls or meetings. Understand when you can lawfully record conversations and how recordings must be handled from a data protection perspective.

2) Move Fast On Takedowns And Clarifications

• If the slander is also being repeated online (e.g. a later post or review), ask the platform to remove it. For your own channels, use clear Website Terms of Use so you can moderate user-generated content and respond quickly.
• Consider a factual correction or limited public response, but avoid escalating the issue or repeating the allegation (the “Streisand effect” risk is real).

3) Send A Targeted Pre-Action Letter

• Often a measured letter demanding a retraction, apology and undertaking not to repeat the slander is enough. Avoid bluster - it’s important you don’t improperly threaten legal action in a way that backfires or creates liability.
• In defamation, the Media and Communications Claims Pre-Action Protocol encourages early exchange of information and attempts to settle. A properly crafted letter can set you up for success.

4) Manage Internal Risks

• If the source is an employee or ex-employee, start fair workplace investigations to address misconduct and prevent further reputational harm.
• Review your social media and communications rules - clear, tailored Workplace Policy documents help prevent staff from making damaging statements about the business or clients.

5) Explore Quick Resolutions

• Propose an agreed correction, retraction, apology and contribution to costs.
• Consider mediation - you often get faster, more targeted outcomes at a fraction of the cost of litigation.

If you receive allegations instead (for example, someone accuses your business of slander), it’s equally important to respond calmly and carefully. Have a look at our practical guide on how to respond to a slander claim.

How To Sue For Slander (Process And Timeframes)

If proportionate steps haven’t resolved the situation - and your evidence supports the serious harm threshold - you can pursue a defamation claim.

1) Assess Your Claim Thoroughly

Defamation claims are specialised. A solicitor will test your prospects against the Defamation Act 2013 and the likely defences, quantify loss, and advise on jurisdiction (most claims issue in the High Court’s Media and Communications List). They’ll also help you comply with the Pre-Action Protocol, which expects early information exchange and genuine settlement attempts before issuing.

2) Comply With The Pre-Action Protocol

You’ll typically send a detailed Letter of Claim identifying the statements, meaning, mode of publication, why they’re false, the serious financial loss suffered or likely to be suffered, and the remedies you seek. The defendant is then expected to respond substantively within the protocol timescales.

3) Issue Proceedings If Needed

If settlement doesn’t happen, your solicitor can issue a claim. Expect the defendant to file a defence raising one or more defences (see below). Procedural directions follow, including disclosure and witness evidence.

4) Remedies You Can Seek

• Damages: to compensate for harm (for companies, financial loss) and sometimes aggravated damages for particularly offensive conduct.
• Injunctions: to restrain repetition (interim injunctions are rare in defamation and require strong proof).
• Corrections/Apologies: admissions and statements in open court can repair reputational harm.
• Orders for removal/takedown: particularly for any later republication online.

5) Costs And Timescales

Defamation litigation can be expensive and time-consuming. There’s no small claims track for defamation. Funding options sometimes include conditional fee agreements, but these depend on case prospects and economics. It’s important to run a cost-benefit analysis against the value of a pragmatic settlement.

Defences You’ll Face (And How To Assess Your Prospects)

Even where a statement hurts, the defendant may have a complete defence. The common ones under the Defamation Act 2013 include:

• Truth: If the defendant proves the statement is substantially true, the claim fails.
• Honest Opinion: Protects opinions (not assertions of fact) based on facts indicated in the publication that an honest person could have held.
• Publication On Matter Of Public Interest: Where the defendant reasonably believed publication was in the public interest.

Other important protections include:

• Privilege: Some settings attract absolute or qualified privilege - for example, fair and accurate reports of proceedings or references given in good faith in certain contexts.
• Website Operator Defence: Operators may avoid liability where they didn’t post the statement and follow the statutory notice-and-takedown process for user-generated content.
• Section 10 (Secondary Publishers): It can be difficult to sue intermediaries where it’s reasonably practicable to sue the primary publisher.

Because these defences are technical, early legal advice can save cost - you want to challenge weak defences but avoid overcommitting where a defence is clearly available.

Related Claims: Malicious Falsehood, Harassment And Reviews

Not every harmful statement fits neatly into defamation. Depending on the facts, you might also consider:

Malicious Falsehood

Where someone makes false statements about your goods or business that cause you financial loss, you may have a malicious falsehood claim. You’ll generally need to show the defendant acted maliciously (for example, knowing the statement was false or not caring whether it was true). This can be useful if the statements don’t meet the “defamatory” threshold but are still damaging in the marketplace.

Harassment

If there’s a course of conduct that amounts to harassment (such as repeated, targeted verbal attacks), the Protection from Harassment Act 1997 may offer a route to an injunction and damages. This can sometimes be a faster, more targeted way to stop ongoing conduct.

Online Reviews And Platforms

If slander is being repeated or morphed into online posts, use the platform’s reporting tools quickly and provide clear evidence of falsity. For any content you host, robust Website Terms of Use make it easier to moderate, remove content, and deal with repeat offenders. If you operate brand or influencer campaigns, keep an eye on review and endorsement rules to avoid creating separate problems - for instance, ensuring paid reviews are compliant.

Evidence Tips And Common Mistakes To Avoid

Evidence wins defamation cases - especially slander, where the words vanish as soon as they’re spoken. A few practical pointers:

• Write a clear chronology and capture witness details while memories are fresh.
• If you’re considering recording discussions on your premises, ensure signage/policies are clear and you understand when and how you can record conversations lawfully.
• Don’t republish the allegation in your own response - you may amplify the harm or risk liability. Keep responses factual and measured.
• Avoid sharing private messages or personal data in public replies unless you’re confident it’s lawful. There are real legal risks in sharing private messages, even if your intention is to “prove the truth”.
• If you receive a defamation letter, don’t panic or lash out. A calm, structured reply can de-escalate and position you well if the matter proceeds. Our guide on how to respond to a slander claim covers the key points.
• Use clear internal rules to reduce repeat risks - strong Workplace Policy documents, staff training, and consistent moderation practices protect your brand from day one.

Key Takeaways

• You can sue someone for slander in the UK, but your business must meet the serious harm threshold - in practice, that means serious financial loss caused (or likely to be caused) by a false, spoken statement.
• Move fast on practical steps before litigation: secure evidence, seek takedowns, send a measured pre-action letter, and consider mediation or settlement to stop the damage quickly.
• Expect technical defences like truth, honest opinion and public interest, plus protections for intermediaries. A realistic early assessment of prospects will save cost and time.
• Consider alternatives where appropriate: malicious falsehood, harassment, contractual or employment avenues may be faster or more effective based on your evidence.
• Be careful with evidence gathering and your public response - understand when you can record conversations, avoid unlawful disclosures, and follow the defamation pre-action protocol.
• Prevent future issues with clear moderation rights in your Website Terms of Use and well-drafted Workplace Policy documents covering staff communications and social media.
