Choosing a business name is not just a branding exercise. In the UK, some words and expressions are treated as sensitive, which means you may need approval before you can register a company name or use a business name. A name can look available on Companies House and still need separate permission. Availability is not the same as approval.
The practical question is which route applies. Some names need written views from a relevant body. Others imply a government connection or contain words protected by other legislation. The packet differs depending on whether you are incorporating a company or seeking business-name permission. Identify the exact word, check its current Annex entry and gather the specified support before spending on branding or filing. This guide explains that permission workflow and the records to prepare. It is general information only, not legal advice.
Does your proposed name actually need prior permission?
A name may need prior approval where it includes a sensitive word or expression. The purpose of these controls is to stop names that could mislead the public or cause harm.
That issue usually arises in four broad situations:
- the name suggests business pre-eminence, status or a specific function
- the name could imply a connection with the UK Government, a devolved administration, a local authority or another specified public authority
- the name includes wording linked to a regulated activity
- the name uses a word whose use is protected or restricted by other legislation
Illustrations often mentioned include words such as British, Institute and Tribunal. They are useful examples of potentially sensitive wording, but they are not automatic approvals and they do not all follow the same criteria.
This is where founders often make the wrong assumption. Seeing a search result that does not show an identical company name does not answer the approval question. A company name can be available in a basic search and still be blocked, queried or later challenged if the required approval was missing or the wording is misleading.
There are also wider naming controls. A name may be refused or challenged if it gives a false impression of a connection with a foreign government or international organisation, if it is misleading about activities, or if it should not have been registered at all. That means the naming exercise is partly an administrative process and partly a risk decision.
Why Annex A, B and C matter
The approval route depends on the exact word or expression and the reason it is controlled. The Incorporation and Names guidance separates the sensitive words process into Annex A, Annex B and Annex C.
Annex A sets out approval criteria for sensitive words and expressions included in the regulations. In practice, that means you need to check the exact entry for the word you want to use and follow the criteria attached to that entry.
Annex B deals with names that could imply a connection with the UK Government, a devolved administration, a local authority or another specified public authority. If your proposed name points in that direction, you need the relevant contact body and the correct supporting approval for that public connection point.
Annex C deals with protected words and words regulated by other legislation. These often overlap with sectors where names can imply permissions, qualifications, functions or regulatory status that a business may not actually have.
The key practical point is that there is no single universal form, no single approval body and no one size fits all letter. You need the current criteria for the precise word you want. Two names that sound similar can fall into different routes if one implies public authority status and the other points to a regulated activity.
A simple example helps. A founder considering Northbridge Institute Services Ltd should not assume the issue is solved by finding no identical match on the register. The word Institute may require a particular approval route and supporting material. By contrast, a name suggesting an official or municipal connection may move into the public authority route instead. The packet changes with the reason the word is sensitive.
What to prepare before you ask for approval
Before contacting the relevant body or sending material with an incorporation application, assemble a clear evidence pack. A rushed email with just the proposed name usually creates delay because the body being asked for written views needs context.
Your preparation should normally cover:
- the exact proposed name, written exactly as you intend to use it
- the entity structure, such as limited company, LLP or business name for a sole trader or partnership
- a short description of the activities the business actually plans to carry on
- the exact Annex route and current approval criteria for the sensitive word
- the identity of the relevant contact body, where one is specified
- the written views, non-objection or permission requested
- a clean submission trail showing what was sent, when, and by whom
Exact wording matters. If you ask for written support for one name and later decide to add another sensitive expression, move the word order around or change the legal ending, you may need to revisit the approval position. Treat the proposed name as a fixed term while you are seeking permission.
It also helps to explain your activities in plain English. If the name could suggest a regulated service, public function or elevated status, the reviewer will want enough information to understand why the name is being requested and whether it could mislead. Overstating future plans can create problems if the business does not match those statements later.
Keep every document and email. If approval is questioned later, being able to show the name requested, the body contacted and the written response received can be very useful.
What goes in a company incorporation packet compared with a business name request?
The paperwork differs depending on what you are doing.
If you are incorporating a company and the proposed company name includes a sensitive word or expression, supporting information such as a letter or email of non-objection from the specified body must be included with the application used to register a company, usually the IN01 filing.
If you are seeking permission to use a business name, the process is not the same as company incorporation. For a business name that includes wording listed in Annex A, B or C, approval is still required and, where appropriate, the written views of the relevant body should be sent to Companies House with the letter seeking permission to use that name.
That difference matters for sole traders and partnerships. Using a business name is not the same thing as forming a company. Some founders assume that if they are not incorporating, the sensitive words rules do not apply in the same way. That is not right. A business name can still need prior approval.
Here is a fictional comparison.
Packet A is for Greenford Tribunal Support Ltd. The founder prepares the incorporation application, checks the relevant criteria for the sensitive word, obtains the specified written support if required, and includes that supporting material with the company registration application.
Packet B is for Greenford Tribunal Support, a sole trader business name. There is no company incorporation form because no company is being formed. Instead, the founder seeks permission to use the business name and sends the required letter and any relevant written views with that request.
These packets may relate to similar words, but they are not interchangeable. Treating a business name request like a company registration filing can slow things down or lead to a refusal.
What approval does not give you
Even when permission is obtained for a sensitive word, that does not solve every legal issue attached to the name.
First, permission to use the name is not an operating licence. If your activities themselves require regulatory authorisation, the company or business still needs whatever approvals apply to that activity.
Second, approval does not confirm that the name is safe from trade mark problems. That is a separate trade mark clearance exercise, and Companies House guidance says you should search the UK Intellectual Property Office trade marks register to check that your proposed business name does not risk infringing an existing trade mark.
Third, approval does not reserve the name against every later complaint. Other naming objections can still arise, including allegations that a name is too like another registered name, misleading about activities, or opportunistically chosen because another party has goodwill in it.
For founders, the message is simple: permission is one box to tick, not a complete brand protection strategy.
What can happen if you use a sensitive word without the right approval?
The immediate risk is that the name may not be accepted, but the issue does not always end there.
For business names, Companies House guidance says that using a business name with a sensitive word without approval is an offence and could lead to a fine and legal action. The exact outcome will depend on the circumstances, so it is better not to build a brand around a name that should not have been launched.
For companies, a registered name may still be challenged if approval was not properly provided or if misleading information was used to support the sensitive word. A company may be told to change its registered name, and Companies House can intervene if the company does not comply with a valid order.
There is also a practical commercial problem. If you print packaging, signage, website copy and sales documents before the approval point is secure, a naming change can become expensive very quickly. Rebranding is rarely just a filing issue. It affects customer communications, supplier documents, marketing assets and domain strategy.
That is why timing matters. Sensitive word checks should happen before launch work, not after the logo has been approved and stationery ordered.
How founders can make the process more efficient
There is no guaranteed processing time and no single timetable that fits every word or approval body. What you can control is the quality of the submission.
A practical approach is to:
- freeze the exact proposed name early
- check whether the sensitive element falls under Annex A, B or C
- identify the correct contact body named for that word, if one is required
- prepare a short, accurate summary of what the business will actually do
- ask for the written views, non-objection or permission in the format the criteria require
- keep records of the response and submit the support with the correct application or permission letter
- delay major branding spend until the naming position is clearer
It is also sensible to think about fallback names. If your preferred name depends on approval from a body that is unlikely to support the wording, a second option can save time and cost.
Another useful discipline is to separate three questions: can the name be filed, can the name lawfully be used, and is the name commercially safe from a brand perspective? Those are related, but they are not identical.
FAQs
Does a Companies House availability search mean I have permission?
No. A search may help you spot obvious conflicts, but it does not replace any prior approval needed for a sensitive word or expression.
Do all sensitive words need approval from the same body?
No. The correct route depends on the exact word and the reason it is restricted. Some words fall under general approval criteria, some relate to government or public authority connections, and some are controlled by other legislation.
Is a company registration application the same as permission to use a business name?
No. A company incorporation filing and a business name permission request are different processes, even if the wording in the proposed name is similar.
If I get permission, does that mean I can carry on the regulated activity?
Not necessarily. Approval for the name is separate from any licence, authorisation or sector-specific permission needed for the activity itself.
Key Takeaways
- A company or business name can need prior approval for a sensitive word even if the name appears available in a search.
- The right route depends on whether the word falls under Annex A, Annex B or Annex C, so check the exact criteria for the exact word.
- Company incorporation filings and business name permission requests need different supporting packets.
- Prepare the exact proposed name, entity structure, planned activities, relevant body contact and written support before filing.
- Permission to use a name does not replace regulatory authorisation, trade mark clearance or wider brand risk checks.
- Using a sensitive word without the right approval can lead to refusal, a forced name change, fines or other legal action.
