Comprehensive guide to objections to company names and dispute procedures in the UK. Learn how to challenge registered names that are too similar, misleading, offensive or opportunistic, how the Company Names Tribunal operates, statutory time limits, compliance with directions from Companies House, and practical steps for resolving name disputes.

When a business is incorporated or changes its registered name in England and Wales, the chosen name must comply with legal rules governing corporate identity and transparency. Occasionally, third parties may object to a company's name, claiming it is too similar to their own name, misleading, or otherwise inappropriate. The law recognises formal objection procedures and dispute mechanisms to resolve such conflicts. This article explains the grounds on which objections can be raised, how the objection process operates under the Companies Act 2006 and related reforms, what remedies are available, the role of the Company Names Tribunal, and practical steps for companies and objectors. The intention is to provide clear, accurate guidance for company owners, solicitors, students, and members of the public.
Legal Basis for Objections
Companies House Powers
Companies House has statutory responsibility to check and approve company names at incorporation and on changes of name. Under the Companies Act 2006 and reforms introduced by the Economic Crime and Corporate Transparency Act 2023 (ECCTA 2023), the Registrar has enhanced powers to refuse or later require changes to company names that:
- Are too similar to existing names on the register;
- Use sensitive words or expressions without appropriate approval;
- Are offensive or likely to facilitate criminal activity;
- Suggest a false or misleading link with government bodies, foreign governments or international institutions; or
- Were wrongly registered due to misleading information or misuse of the register.
If a company's name falls into these categories, Companies House may reject the proposed name or issue a direction to change the name within a specified period, typically at least 28 days. Failure to comply can result in statutory sanctions, including fines and compulsory renaming by the Registrar.
Objections by Third Parties
Separately from actions taken directly by Companies House, third parties with legitimate interests can challenge an existing registered company name under section 69 of the Companies Act 2006. This provision allows any person - including companies and individuals - to apply to the Company Names Tribunal (CNT) if they believe a company's name is:
- Identical or too like their own name, such that the public is likely to confuse the two; or
- Registered opportunistically with the intention of extracting money or consideration from the complainant or preventing the complainant from using their name.
The CNT is an independent adjudicatory body operated by the Intellectual Property Office (IPO), tasked with resolving disputes between competing parties over registered names.
Grounds for Objection
“Too Like” Another Name
A classic ground for objection is that a company's registered name is too similar to an existing name on the Companies House index. Companies House will consider a name too like an existing one if they differ only by minor characters, punctuation or sound, and this similarity is likely to cause public confusion. The assessment is based on how the names appear and sound, not on business activities or geographic attributes. Objections of this type commonly arise within 12 months of registration.
Opportunistic Registration
A company may be accused of opportunistic registration if it registers a name not for genuine business purposes but to exploit another party's goodwill, reputation or brand equity. If the Tribunal upholds such an objection, the company may be ordered to change its name, and Companies House can enforce that order if the company refuses to comply.
Misleading, Offensive or Criminal Use
Reforms under the ECCTA 2023 have strengthened the Registrar's ability to object to names that are potentially misleading or connected with fraudulent or criminal purposes. These provisions allow rejection of applications or directions to change names where the name suggests an illegitimate connection (for example, to government or foreign entities) or contains offensive terms. Companies House may proactively query registered names and act where evidence does not satisfy its requirements for legitimacy.
How to Object to a Company Name
Filing an Objection
A formal objection under section 69 is made by submitting an application to the Company Names Tribunal. The applicant must set out:
- The grounds of objection (e.g., similarity, opportunistic registration);
- Evidence showing the complainant's interest (such as goodwill in the name);
- Why the registered name is likely to mislead or harm the complainant's interests.
There is no standard Government form for objections, but guidance and application details are available on the IPO's website and through official publications.
Time Limits
While objections based on similarity can be raised typically within 12 months of registration, those founded on misleading information or misuse of sensitive words may be raised within five years of registration or a change of name, provided conditions such as unmet approval requirements are established.
Defences and Amendments
The respondent company may defend an objection by demonstrating that:
- The name was adopted in good faith;
- There is no significant effect on the objector's interests; or
- The objection does not satisfy the statutory criteria.
Notably, reforms have removed or limited some former statutory defences, such as easy reliance on prior trading or preparation costs, making it harder for objection responses based solely on business activity to succeed.
Role of the Company Names Tribunal
Once an objection is lodged, the Company Names Tribunal considers written submissions and evidence from both the objector and the respondent company. The Tribunal may decide to:
- Uphold the objection and order the company to change its name;
- Dismiss the objection if it is unsubstantiated; or
- Make other directions relevant to the dispute.
If the respondent fails to comply with an order, the Tribunal can instruct Companies House to change the company's name, potentially replacing it with the company number on the register.
Compliance with Registrar Directions
If Companies House itself directs a company to change its name - for example due to similarity, misleading implication or misuse of sensitive terms - the company is required to comply within a specified period, usually 28 days. Failure to do so may result in Companies House selecting a new name on the company's behalf or enforcing statutory penalties. Continuing to trade under a directed name after the compliance period can be an offence with fines.
Practical Considerations and Risks
Costs and Legal Advice
Objection proceedings and name disputes can involve costs, including professional fees for evidence preparation and, in some cases, Tribunal or legal costs. Businesses should consider seeking legal or IP advice to assess the strength of their case and evidence.
Brand Protection
Companies should undertake thorough name clearance searches of the Companies House register, trade mark databases and other business name sources before incorporation to avoid potential objections and disputes. Early identification of conflicts reduces the risk of costly name changes or legal challenges.
Goodwill and Reputation
An objection based on similarity or opportunistic registration is strongest where the objector can demonstrate goodwill in their name or brand. Goodwill refers to reputation and public recognition built over time.
Key Takeaways
Disputes over company names in the UK can arise where names are too similar to existing companies, misleading, offensive, or opportunistically registered. The Companies Act 2006 and subsequent reforms under the Economic Crime and Corporate Transparency Act 2023 empower Companies House to refuse or direct changes to names and enable third parties to challenge names through the Company Names Tribunal. Objections must be supported with clear evidence and are subject to statutory time limits. Understanding the objection process, available defences, and practical steps before and after registration helps companies manage risks, protect brands, and ensure compliance with legal requirements.
