Company name approval process explained under UK company law, including Companies House rules, sensitive word restrictions, “too like” name tests, trademark considerations, and legal requirements for incorporation in England and Wales.

When incorporating a company in England and Wales, one of the first legal requirements is selecting an acceptable company name. This name is not freely chosen in an unrestricted sense. It must comply with statutory rules administered by Companies House under the Companies Act 2006 and associated regulations.
The company name approval process ensures that names are not misleading, are not too similar to existing registered companies, and do not contain restricted or sensitive terms without prior consent. If a name fails to meet these requirements, Companies House will refuse registration or require a change after incorporation.
Legal Framework for Company Name Approval
Company name rules are primarily governed by:
- Companies Act 2006
- The Company, Limited Liability Partnership and Business Names (Sensitive Words and Expressions) Regulations 2014
- Companies House guidance on incorporation and naming rules
These rules apply to:
- registered company names
- business (trading) names
- limited liability partnerships (LLPs)
The purpose is to prevent public confusion, protect regulated sectors, and prevent misuse of official or sensitive terminology.
Core Principles of Company Name Approval
Companies House assesses proposed names against three main principles:
1. Distinctiveness
A company name must not be:
- identical to an existing registered company
- “too like” another name already on the register
- misleadingly similar in spelling, pronunciation, or structure
Even minor differences such as punctuation or spacing may not be sufficient if the overall impression is the same.
2. Non-Misleading Character
A name must not mislead the public about:
- the company's activities
- its status or size
- its relationship with government or public bodies
Names implying official authority or public function may be rejected.
3. Compliance with Sensitive Word Restrictions
Certain words require prior approval before they can be used in a company name.
These include words that suggest:
- government or public authority connections (e.g. “Authority”, “Government”, “UK”)
- regulated industries (e.g. “Bank”, “Insurance”)
- professional or academic status (e.g. “Institute”, “Chartered”)
- prestige or official recognition (e.g. “British”, “Royal”)
Some words require supporting documentation or a “letter of non-objection” from a relevant regulator before Companies House will accept the name.
Step-by-Step Company Name Approval Process
Step 1: Initial Name Selection
Applicants choose a proposed company name and check availability using the Companies House register.
At this stage, the name must:
- not already exist
- not be too similar to another name
- comply with general naming rules
Step 2: Sensitive Word Screening
Companies House automatically screens names for restricted or sensitive words.
If the name contains such a term:
- the application cannot proceed automatically
- manual approval or external consent may be required
- additional documentation may be requested
Step 3: Formal Approval (If Required)
Where sensitive words are involved, approval may be required from:
- government departments
- regulatory bodies (for financial or professional terms)
- other relevant authorities depending on the word used
Only after approval is granted will Companies House accept the application.
Step 4: Registration Decision
Companies House will either:
- approve the name and proceed with incorporation
- reject the name outright
- require modification or resubmission
Step 5: Post-Incorporation Challenges
Even after registration, a company name may be challenged if it is:
- too similar to another trading name
- misleading
- registered using incorrect or incomplete information
In some cases, the Company Names Tribunal may order a name change.
Restrictions on Company Names
1. “Same as” and “Too Like” Names
Names may be rejected if they are effectively identical to an existing company, including where differences are minimal.
Examples of insufficient differences include:
- punctuation changes
- plural vs singular forms
- minor spelling variations
- similar pronunciation
2. Offensive or Inappropriate Names
Companies House may reject names that a reasonable person would find offensive. This includes names involving:
- explicit language
- discriminatory terms
- criminal or violent references
Hundreds of applications are rejected annually on this basis.
3. Misleading Business Activity Names
Names suggesting activities the company does not perform may be refused. For example:
- “National Tribunal Services Ltd” for a private consultancy
- “UK Government Advisory Ltd” without official affiliation
4. Trademark Conflicts
Even if a name is accepted by Companies House, it may still infringe trademark law.
This can lead to:
- legal action for passing off
- injunctions preventing use of the name
- forced rebranding
Company registration does not grant trademark protection.
Legal Effects of Name Approval
Once approved and registered:
- the name appears on the public register
- the company must use the name in all official documents
- legal proceedings must be brought under that name
- the name becomes part of corporate identity under law
However, approval does not guarantee exclusivity outside the Companies House register.
Common Legal Issues
1. Assuming Registration Confers Ownership
Registering a company name does not grant exclusive rights. Trademark law operates separately.
2. Delayed Rejection
Some names may be accepted initially but later challenged, resulting in forced change.
3. Business Name vs Registered Name Confusion
A company may trade under a different name, but both must comply with naming rules if sensitive terms are used.
4. Re-Use of Restricted Names
If a name has been ordered to change, reusing it in a similar form is generally prohibited without approval.
Practical Considerations at Formation
When choosing a company name, founders typically assess:
- availability on Companies House register
- trademark availability at the UK Intellectual Property Office
- potential regulatory restrictions
- reputational implications
- long-term branding suitability
Careful review at formation reduces the risk of rejection or later disputes.
Common Questions
Can any name be used if it is available?
No. Availability is only one requirement. The name must also comply with statutory restrictions.
Can Companies House refuse a name after incorporation?
Yes, in limited circumstances such as misleading registration or successful objection.
Is trademark approval required before incorporation?
No, but failure to check trademarks may result in later legal disputes.
How long does approval take?
Standard names are approved during incorporation. Sensitive names may take longer due to external approvals.
Key Takeaways
The company name approval process in England and Wales is governed by statutory rules designed to ensure clarity, prevent confusion, and protect regulated terms. Companies House checks proposed names for similarity to existing companies, compliance with sensitive word restrictions, and potential misleading content.
While many names are approved automatically during incorporation, others require external consent or are rejected entirely. Importantly, approval does not guarantee exclusive ownership, and trademark law operates separately.
