Restricted Company Names: Legal Rules and Examples

When forming a company in England and Wales, the proposed name must comply with statutory restrictions designed to prevent confusion, misuse of official terminology, and misleading representations. These restrictions are part of the company name rules enforced by Companies House under the Companies Act 2006 and related regulations.

A “restricted company name” is any proposed name that contains words or expressions which cannot be used freely or which require approval before incorporation. If a restricted name is used without compliance, Companies House may refuse registration or require a mandatory name change after incorporation.

Legal Framework for Restricted Company Names

The regulation of company names is governed by:

• Companies Act 2006
• Company, Limited Liability Partnership and Business Names (Sensitive Words and Expressions) Regulations 2014
• Companies House naming guidance and administrative practice

These rules apply to all incorporated companies and are designed to ensure:

• transparency in the business register
• protection of consumers from misleading names
• safeguarding of regulated professions and industries
• prevention of implied government or official endorsement

What Are Restricted Company Names?

Restricted company names are names that include words or expressions subject to legal control. These controls may involve:

• outright prohibition
• requirement for prior approval
• requirement for supporting documentation
• restriction based on business activity

Restriction applies even if the name is otherwise available on the register.

Categories of Restricted Company Names

1. Government and Public Authority Terms

These names suggest official status or public authority involvement.

Common restricted terms include:

• “Government”
• “UK” or “United Kingdom” (in certain contexts)
• “National”
• “British”
• “Authority”
• “Council”

These are restricted to prevent the public from being misled into believing the company is state-affiliated.

Example (restricted without approval):

• “UK National Housing Services Ltd”

2. Financial Services and Banking Terms

Financial terms are heavily restricted due to consumer protection risks.

Common restricted terms include:

• “Bank”
• “Banking”
• “Insurance”
• “Assurance”
• “Credit”
• “Mortgage”
• “Fund Management”

Use of these terms often requires authorisation from the Financial Conduct Authority (FCA) or evidence of regulated activity.

Example (restricted):

• “Premier Investment Bank Ltd”

3. Professional and Accredited Status Terms

These terms imply qualifications or institutional authority.

Common restricted terms include:

• “Chartered”
• “Institute”
• “Royal”
• “University”
• “College”

Approval is typically required from relevant professional bodies or government departments.

Example (restricted):

• “Royal Institute of Engineering Ltd”

4. Legal and Judicial Terms

Certain words suggest legal authority or formal justice system involvement.

Common restricted terms include:

• “Solicitors”
• “Barristers”
• “Court”
• “Tribunal”
• “Legal Services” (in regulated contexts)

These are restricted to prevent misrepresentation of legal status or professional qualification.

Example (restricted):

• “London Court Legal Services Ltd”

5. Sensitive Prestige and Geographic Terms

Some words may imply official endorsement or national significance.

Common restricted terms include:

• “European”
• “International” (in misleading contexts)
• “Global” (depending on usage)
• “British” (context-dependent)

Example (restricted if misleading):

• “British Export Authority Ltd”

Legal Tests Applied to Restricted Names

Companies House applies several key tests when assessing restricted names:

1. Misleading Impression Test

A name must not mislead the public about:

• the nature of the business
• regulatory status
• size or scope of operations
• official affiliation

2. Sensitive Word Test

If a name contains a sensitive word, it is automatically flagged for review or rejection unless approval is provided.

3. “Same as” and “Too Like” Test

Even if a name does not contain restricted words, it may still be rejected if it is too similar to an existing company name.

4. Public Interest Test

Names that may damage public trust in regulated industries are subject to stricter scrutiny.

Approval Process for Restricted Company Names

Where a restricted name is proposed, the following process applies:

Step 1: Identification of Restricted Term

Companies House identifies whether the name contains sensitive or restricted language.

Step 2: Requirement for External Consent

Depending on the term, approval may be required from:

• Financial Conduct Authority (for banking or insurance terms)
• HM Treasury or other government departments
• professional regulatory bodies
• Cabinet Office (for terms like “Royal”)

Step 3: Submission of Supporting Evidence

Applicants may need to provide:

• proof of authorisation or licensing
• evidence of professional status
• justification for use of the term
• regulatory approval letters

Step 4: Companies House Decision

Companies House will either:

• approve the name
• reject the name
• request modification

Legal Consequences of Using Restricted Names Incorrectly

If a company uses a restricted name without proper approval, consequences may include:

1. Refusal of Incorporation

The application may be rejected outright.

2. Mandatory Name Change

A company may be required to change its name after registration.

3. Company Names Tribunal Action

Third parties may object, and the tribunal can order a name change.

4. Regulatory Enforcement

In regulated sectors, misuse of restricted terms may lead to:

• FCA enforcement action
• trading restrictions
• reputational damage
• civil claims for misrepresentation

Examples of Restricted vs Acceptable Names

Government-related terms

• Restricted: “UK Government Advisory Services Ltd”
• Potentially acceptable: “UK Advisory Solutions Ltd” (if not misleading)

Financial terms

• Restricted: “London Bank Holdings Ltd”
• Acceptable only with approval: “London Investment Bank Ltd”

Professional terms

• Restricted: “Royal Legal Institute Ltd”
• Possibly acceptable with consent: “Institute of Legal Studies Ltd”

Legal services terms

• Restricted: “Court Litigation Services Ltd”
• Acceptable alternative: “Legal Dispute Services Ltd”

Common Mistakes in Restricted Name Applications

1. Assuming Branding Justifies Use

Marketing intent does not override legal restrictions.

2. Ignoring Regulatory Requirements

Many applicants fail to obtain FCA or professional body approval before submitting incorporation applications.

3. Misinterpreting Word Context

Some words are only restricted in certain contexts, but applicants often assume blanket permission.

4. Overlooking Post-Incorporation Challenges

Even approved names can later be challenged through tribunal proceedings.

Practical Considerations at Company Formation

When selecting a company name, founders should:

• check Companies House guidance on sensitive words
• assess whether regulatory approval is required
• consider trademark implications
• evaluate whether the name could mislead the public
• prepare supporting documentation early if needed

Early planning reduces delays in incorporation and avoids rejection risks.

Common Questions

Are all restricted names automatically rejected?

No. Many can be used with prior approval from the relevant authority.

Can a restricted name be challenged after incorporation?

Yes. Through the Company Names Tribunal or regulatory enforcement.

Does Companies House provide a list of restricted words?

Yes, but the list is not exhaustive and context is always considered.

Can trading names bypass restrictions?

No. Trading names must also comply with misleading and sensitive word rules.

Key Takeaways

Restricted company names are governed by UK company law to prevent misleading representations and protect regulated sectors. These restrictions apply to government-related terms, financial services language, professional titles, and words implying official authority.

Before incorporation, restricted names may require approval from Companies House or external regulators such as the Financial Conduct Authority or professional bodies. Failure to comply can result in rejection, enforcement action, or mandatory name changes.

Careful assessment of naming rules at the formation stage is essential to ensure compliance and avoid delays or legal disputes.
