Passing Off Law in the UK: What Businesses Need to Know

Your brand is one of your most valuable business assets. Even before you’ve registered anything, UK law gives you tools to stop others riding on your reputation. That’s where passing off comes in.

If another business uses a name, logo, packaging, domain or “look and feel” that misleads customers into thinking they’re connected with you, you may have a passing off claim. Likewise, you need to make sure your own branding and marketing don’t accidentally step on someone else’s toes.

In this guide, we’ll break down passing off law in the UK in plain English, share practical steps to protect your brand, and explain what to do if a competitor copies your “get‑up”.

What Is Passing Off Under UK Law?

Passing off is a common law claim that protects the goodwill you’ve built in your business. In simple terms, it stops someone from misrepresenting their goods or services as being yours (or connected with you) in a way that causes damage.

Courts often refer to the “classic trinity” from case law. To succeed, you generally need to show three things:

• Goodwill – You have built up reputation and customer recognition in the UK for the relevant name, logo, get‑up, product shape, packaging, domain or other distinctive sign.
• Misrepresentation – The other party’s use misleads the public into believing their goods or services are yours, or that there is a commercial connection (for example, endorsement or affiliation).
• Damage – You suffer (or are likely to suffer) damage, such as lost sales, dilution of your brand, harm to reputation, or loss of control over your goodwill.

Passing off is flexible. It can protect classic indicators like trading names and logos, but also wider “get‑up” (colour schemes, product shapes, labels, website look) and even domain names or social media handles if they carry goodwill. There’s also “extended passing off”, which protects collective goodwill in descriptive terms with a particular reputation (for example, Champagne as a style originating from a geographic region).

Unlike registered trade marks, passing off doesn’t require registration. However, it does require you to prove facts about your goodwill, the misrepresentation and damage, which can be evidence‑heavy. For many small businesses, a combination of passing off and a registered trade mark provides the best protection.

Passing Off vs Trade Marks And Copyright: What’s The Difference?

It’s easy to mix up passing off with other IP rights, so here’s a quick overview of how they differ and work together.

Registered Trade Marks

A UK trade mark gives you statutory rights to stop confusingly similar use for the registered goods/services. You don’t need to prove goodwill-registration is your starting point. It’s generally quicker to enforce than passing off and easier to put potential infringers on notice.

That said, plenty of small businesses rely on passing off when they haven’t registered yet, or when an infringer is copying aspects outside the strict scope of their registration (for example, a look‑alike get‑up). For robust protection, aim to trade mark your logo and key brand elements early, then use passing off to cover the rest.

Copyright

Copyright protects original creative works (like your logo artwork or product photos). It doesn’t protect names or short phrases. If someone lifts your artwork, that’s a copyright issue. If they copy your branding “look” so customers think they’re you, that’s passing off. These claims often run together-copyright can address direct copying of assets, while passing off addresses market confusion and damage to goodwill. For more on enforcement risks, see our guide to copyright.

Honest Use And Descriptive Use

Neither trade mark law nor passing off prevents fair descriptive use. But if your use goes beyond description and causes confusion about origin or endorsement, you may be crossing the line into passing off.

Common Passing Off Scenarios For SMEs

Here are everyday situations where passing off law in the UK often comes up for small businesses:

• Look‑alike packaging or “get‑up”. A rival adopts similar colours, fonts, shapes or labelling so their product looks like yours on a shelf or website.
• Similar trading name. Another local business starts trading under a name that’s deceptively close to yours, especially in the same region or sector. Understanding the rules on trading names is key here.
• Domain names and social handles. A third party registers your brand as a domain or handle, or a confusingly similar variant, and uses it commercially.
• Google Ads and keywords. Competitors bid on your brand term and write ad copy that implies affiliation (for example, “official” or using your brand in a misleading way). Keyword bidding itself isn’t automatically unlawful; it’s about whether the overall presentation misleads.
• Influencer or affiliate claims. A promoter implies a partnership or endorsement that doesn’t exist, creating confusion. Ensure you have clear controls in your influencer marketing and brand ambassador content.
• Reseller misrepresentation. An authorised reseller presents itself as the manufacturer or “official store”, or an unauthorised seller uses your marks and branding in a way that confuses customers. Well‑drafted Distribution Agreement or Reseller Agreement terms help manage this risk.

If any of these feel familiar, don’t panic. Passing off law is designed for exactly these sorts of situations-and there are practical steps you can take quickly.

How Do You Prove Passing Off?

For a small business, the most important question is “what evidence do I need?” The stronger your evidence, the more persuasive your pre‑action letter-and the more likely you’ll resolve the issue without court.

1) Proving Goodwill

Goodwill is about recognition in the minds of customers in the UK. Useful evidence includes:

• Length of trading, sales figures and growth
• Marketing spend, campaigns and reach (online and offline)
• Press coverage, awards and customer testimonials
• Website traffic and social engagement for your brand terms
• Distinctive visual elements (colour schemes, packaging, product shapes) used consistently over time

Keep records. Screenshots, dated packaging drafts, and brand guideline documents make a real difference when you need to show a court that customers associate your get‑up with you.

2) Proving Misrepresentation

You don’t need to prove an intention to deceive-only that the conduct is likely to mislead the public. Helpful evidence includes:

• Side‑by‑side comparisons of names, logos, packaging, website layouts or domain/handle use
• Customer complaints or messages showing actual confusion
• Misleading ad copy, website text or social posts implying endorsement or affiliation
• Store shelf photos or online listings showing how products appear to customers in context

Consumer surveys are sometimes used, but they must be carefully designed to avoid bias and may not be cost‑effective for every case. Often, documented examples of real confusion are more persuasive.

3) Proving Damage

Damage can be loss of sales, dilution of your brand’s distinctiveness, or harm to your reputation (for example, poor quality copycats leading consumers to think less of your brand). Evidence can include:

• Drop in sales or conversion rate coinciding with the infringing activity
• Customer complaints attributed to the other party’s product or service
• Increased marketing spend needed to correct confusion
• Harm to premium positioning or pricing power

What Remedies Are Available For Passing Off?

If you prove passing off, UK courts can grant a range of remedies to protect your business and compensate you for the harm caused. Common outcomes include:

• Injunctions – Court orders stopping the infringing use (for example, requiring a name change, packaging change, or removal of misleading claims).
• Damages or an account of profits – Compensation for your loss or surrender of profits the infringer made due to the misrepresentation.
• Delivery up or erasure – Destruction or removal of infringing materials (packaging, labels, marketing assets, domain transfers).
• Costs – A contribution to your legal costs, subject to court rules and the track your case is on.

Most matters settle before trial. A well‑prepared letter before action, backed by clear evidence and a pragmatic proposal (for example, a rebrand within a set timeframe + undertakings), often resolves disputes quickly and cost‑effectively.

What To Do If Someone Is Passing Off Your Business

Speed matters. The longer confusing conduct continues, the more risk to your goodwill. Here’s a practical approach.

1) Gather Evidence

• Take dated screenshots, store photos and copies of ads.
• Record examples of customer confusion (emails, messages, reviews).
• Note when the activity started and where it appears (stores, marketplaces, search ads).

2) Assess Your Rights

• Consider both passing off and any registered rights (for example, trade marks). If you don’t have registrations yet, it may be time to register a trade mark for the brand elements that matter most.
• Work out the jurisdictions involved (UK only, or international activity).

3) Send A Tailored Letter Before Action

A solicitor’s letter sets out your goodwill, the misrepresentation, the damage, and what you want (for example, stop use, rebrand by a deadline, undertakings not to repeat, transfer of domains, disclosure of sales, and costs). A firm but constructive tone often keeps negotiations on track.

4) Consider Fast, Proportionate Enforcement

• IP Enterprise Court (IPEC). The IPEC small claims track is designed for simpler IP disputes (including passing off) with damages up to £10,000. It’s generally quicker and costs are more controlled than the High Court.
• Interim injunctions. In urgent cases with clear evidence of confusion, you may seek an interim injunction to stop the behaviour pending trial.
• Platforms and marketplaces. If the issue is on a marketplace or social platform, report the infringement using their brand protection channels while your legal process runs.

5) Build Settlement Terms That Stick

If you settle, ensure undertakings are clear and enforceable. You might also agree on a short transition period, stock run‑down rules, and a contribution to your costs. Where brand assets were copied, consider requiring destruction or transfer (for example, domains or social handles) plus a mutual non‑disparagement clause.

How To Avoid Accidentally Committing Passing Off

From a risk management perspective, make sure your branding and marketing don’t create a false impression of origin or endorsement.

• Search thoroughly. Before adopting a name, logo or get‑up, search Companies House, trade mark registers, app stores, domains, marketplaces and social media. Check for look‑alike packaging in your sector.
• Be careful with comparisons and endorsements. Avoid “official”, “authorised”, “partner” or “as used by ” unless it’s true and you can substantiate it. UK consumer law also prohibits misleading claims-see our guide on false advertising.
• Use disclaimers sensibly. A small disclaimer won’t fix a confusing overall impression. Prioritise clear, distinctive branding.
• Manage resellers and influencers. Use clear agreements to control how partners use your brand and what they can say. Consider a Brand Ambassador Agreement and ensure promotional content follows the ASA CAP Code.
• Respect others’ IP. Don’t replicate a competitor’s get‑up, even if you don’t copy their logo. If in doubt, get advice from an IP lawyer before launch.

Set Up Your Brand Protection From Day One

The best way to avoid disputes is to put a simple brand protection plan in place early. This isn’t about over‑lawyering-it’s about reducing distractions so you can focus on growth.

1) Lock In Registrations

• Trade marks. Register your core brand name, logo and any distinctive packaging or tagline in the key classes you sell in. It’s cost‑effective insurance and pairs well with passing off. You can start with a UK filing and expand later.
• Domains and handles. Secure obvious domains and social handles to prevent misuse. If a deal requires shared use, put a simple Domain Name Licence in place.

2) Use Consistent, Distinctive Get‑Up

Distinctiveness makes passing off easier to enforce because it strengthens the link in customers’ minds. Create brand guidelines and stick to them across packaging, website design and retail displays.

3) Put Practical Contracts In Place

• Suppliers and distributors. Include brand usage rules and marketing controls in your Distribution Agreement or reseller terms.
• Creators and agencies. If third parties create your brand assets, ensure you own them with an IP Assignment and control how they’re used with an IP Licence.
• Ambassadors and affiliates. Use clear do’s and don’ts for claims, endorsements and brand use, and align them with ASA rules.

4) Build A Quick Response Playbook

Keep a short internal playbook so your team knows what to do if look‑alike issues pop up: who captures evidence, who drafts the first message, when to escalate, and who signs off legal letters. A swift, coordinated response often resolves problems before they escalate.

Costs, Courts And Timelines: What Should A Small Business Expect?

Every dispute is different, but here’s a realistic picture for SMEs.

• Early resolution. Many passing off issues resolve after an initial letter and brief negotiations-often within 2–6 weeks if both sides are pragmatic. Costs at this stage are typically a fraction of litigation.
• IPEC small claims track. For simpler disputes with damages up to £10,000, the IPEC small claims track can be an efficient route. Costs recovery is limited, which keeps risk proportionate for both sides and incentivises settlement.
• IPEC multitrack or High Court. Complex, higher‑value disputes may go to the IPEC multitrack or High Court, with higher costs and longer timelines. Interim injunctions are possible where urgency and merits justify them.
• Risk management. Even where you’re in the right, litigation can be time‑consuming. A clear strategy-aimed at stopping the confusion quickly and protecting your reputation-usually delivers the best business outcome.

It can be overwhelming to know which path to take-so it’s wise to get tailored advice early. A short strategy call can make the difference between a two‑week fix and a six‑month distraction.

FAQs About Passing Off Law In The UK

Is Passing Off The Same As Trade Mark Infringement?

No. Trade mark infringement relies on registered rights under the Trade Marks Act 1994, while passing off relies on your unregistered goodwill. You can bring both claims where facts support them.

Do I Need To Prove Actual Confusion?

No, but evidence of actual confusion is very helpful. You only need to show a misrepresentation likely to deceive a substantial number of relevant customers.

Can Small Businesses Afford To Enforce Their Rights?

Yes-many disputes resolve at the pre‑action stage. Where court is needed, IPEC procedures are designed to keep IP disputes proportionate for SMEs.

What If I Only Trade Online?

Online businesses build goodwill too. Use analytics, reviews and sales records to evidence your reputation with UK consumers.

How Do I Reduce The Risk Of Being Accused Of Passing Off?

Do thorough clearance searches, adopt distinctive branding, avoid implying endorsement, and get quick advice if you’re unsure. Strong brand hygiene from day one will save you headaches later.
