REGISTER YOUR COMPANY NAME IN UNDER 5 MINUTES

Company Name Checker Check if your company name is available

Choosing a limited company name

If you are setting up a limited company with your own choice of name you need to check the company name at Companies House. The formation of a UK limited company is only allowed if the company name is not already in use. An own name limited company registration must also pass a sensitive name check at Companies House.

Certain words are restricted for use in the formation of a UK limited company name unless they can be justified to the satisfaction of Companies House. These are known as sensitive words. As part of the company formation process you can check a company name here and we will perform a sensitive word check at Companies House.

Our staff will be able to guide you if you wish, but your attention is drawn to Companies House guidance with effect from 1st October 2009 , which we have listed below for ease of reference.

The content below has been taken from Companies House guidance notes

Before choosing a name you may wish to check the Trade Marks Register of the UK Intellectual Property Office to ensure that the proposed company name is not identical or similar to an existing trade mark. Furthermore, there is no guarantee that the name you choose will not impinge upon a business name that is neither a trade mark nor registered at Companies House. A third party may in all cases issue civil proceedings for "passing off." These are not common occurrences but it is something you should bear in mind. In the event that the name you have chosen faces a challenge we recommend that you take appropriate professional advice.

Before you incorporate your company you will need to choose a name. The name you choose must not be identical or the "same as" another name appearing on the index of company names, even if you are already using the name as a sole trader or partnership

The characters and punctuation that can be used in a company's name are specified in regulations. While accents may not be included in a company's registered name, this does not prevent their being included in the company's stationery.

You will only have to seek prior approval for a company's name if it includes a specified word or expression or it implies a connection with Her Majesty's Government or a devolved administration or a local authority or a specified official body.

You cannot reserve a name. We cannot guarantee to process applications in strict order of the time or date of their receipt and in general we process applications sent by electronic software filing more quickly than paper applications.

Choosing a company name

Can I choose any name I want for my proposed company?

If your company is:

  • a private limited company - its name must end in "limited" or, if its registered office is in Wales, in "cyfyngedig" or in the permitted alternatives, ie "ltd" or "cyf". There is an exception to this rule: a private company limited by guarantee can apply for an exemption if:
    • the objects of the company are the promotion or regulation of commerce, art, science, education, religion, charity or any profession, and anything incidental or conducive to any of those objects;
    • the company's articles:
      • require its income to be applied in promoting its objects
      • prohibit the payment of dividends, or any return of capital, to its members; and
      • require each member to contribute to the assets of the company if it is wound up during the time that he is a member or within 1 year of him ceasing to be a member
  • a private unlimited company - its name may end in "unlimited" but it is not required to do so;
  • a public limited company -its name must end in "public limited company" or, if its registered office is in Wales, in "cwmni cyfyngedig cyhoeddus" or in the permitted alternatives, ie "plc" or "ccc" with or without full stops.

There are a number of controls and restrictions which apply to the main part of your company's name. These are set out in 'The Company and Business Names (Miscellaneous Provisions) Regulations 2009' (SI 2009/1085). Further information on restricted and sensitive names is included in chapter 3. Companies House administers these controls on behalf of the Secretary of State and we will not register a company in a name if:

  • its use would constitute an offence or it is offensive;
  • the name suggests a connection with Her Majesty's Government or a devolved administration or a local authority or certain specified public authorities
  • it includes a sensitive word or expression unless certain tests are satisfied and you provide a statement of support by the appropriate government department or other official body. (see chapter 3)
  • it includes characters, signs, symbols and punctuation which are not permitted. A list of permitted characters, signs, symbols and punctuation is included in 'The Company and Business Names (Miscellaneous Provisions) Regulations 2009' (SI2009/1085);
  • it is identical to another name appearing on the index of company names or differs from an another name in a trivial way, ie is effectively the "same as" an existing name. (A name that is effectively the "same as" another's may still be permitted if the two companies will be part of the same group and if the existing company agrees to the other taking the proposed name.) Further information about "same as" names is provided in question 2.
  • it does not end with the appropriate designator (or permitted abbreviation) for the company type (e.g. "limited" or "ltd"; "public limited company" or "plc"; "unlimited");
  • if any of the designators "limited", "ltd", "unlimited", "cyfyngedig", "cyf", "anghyfyngedig" is used but:
    • one or more characters have been omitted;
    • one or more characters, symbols signs or punctuation has been added; or
    • any one or more of these characters have been replaced with one or more other characters, symbols, signs or punctuation
  • if, in the case of a company limited by guarantee exempt from using "limited", the name concludes with "unlimited" or "anghyfyngedig" or one of the words or expressions (or permitted abbreviation) set out in (a) to (f) below in such a way as to mislead the public as to the legal form of the company if included in the registered name of the company.
  • if, in the case of an unlimited company, the name concludes with "limited" or "cyfyngedig" or one of the words or expressions (or permitted abbreviations) set out in (a) to (f) below in such a way as to mislead the public as to the legal form of the company if included in the registered name of the company.
  • If the name includes in any part of the name any of the expressions or abbreviations in (g) to (u) below

What does 'same as' mean?

A name is the 'same as' another name appearing on the index of company names if it is either identical to an existing name or would be deemed to be essentially the same because the name differs only by minor elements which the law requires us to disregard when comparing the two names. For example, we would disregard plurals or certain types of punctuation marks when comparing names.

Examples of what we will disregard or ignore when comparing names are:

  • any of the designated name endings (including permitted abbreviations with or without full stops or their welsh equivalents) set out in question 1 above, for example, "limited", "unlimited", "public limited company" or "community interest company";
  • words and expressions such as "biz", "co", "co uk", "co.uk", "com", "company", "UK", "United Kingdom", "Wales", "Cymru", "net", "GB", "Great Britain", "org.uk", "services", "international" (but see question 3 of this chapter for circumstances when these will not be ignored);
  • a blank space between or after a word, expression, character, sign or symbol;
  • punctuation including a full stop, comma, colon, semi colon, hyphen, apostrophe, bracket, exclamation mark, question mark;
  • permitted characters "*", "=", "#", "%" and "+" if they are used as one of the first three characters in a name
  • "s" at the end of a name;
  • "the" and "www" at the beginning of a name
  • any but the first 60 characters in a name

In addition, we will treat certain words and expressions as if they were the same, eg "and" and "&", "plus" and "+", "1" and "one", "6" and "six", "€" and "euro", "$" and "dollar", "%" and "percent", "@" and "at",

The 'same as' rules are included in 'The Company and Business Names (Miscellaneous Provisions) Regulations 2009' (SI2009/1085) which we strongly advise you to read before you apply to incorporate your chosen name.

Please note, the "same as" rules do not prevent someone else trading under a name that is the same as a company's registered name in all respects excepting only the designator (eg "ltd").

Are there any exceptions to the 'same as' rules?

Yes. Where 2 companies are in the same group, they may have names that differ only by certain specified words and expressions (such as "biz", "co", "co uk", "co.uk", "com", "company", "UK", "United Kingdom", "Wales", "Cymru", "net", "GB", "Great Britain", "org.uk", "services", "international"). This is permitted only if the member of the group whose name is already on the Registrar's Index of company names gives its consent to the other company adopting the name that differs from its own in this way. The application for the proposed name must include:

  • a copy of a statement in which the existing company consents to the other company adopting the proposed name and confirms it will be part of the same group

Can you give some examples of 'same as' names?

If 'Hands Limited' is already registered we would reject the following applications:

  • Hand-S Limited or Ltd;
  • H and S Public Limited Company (or PLC)
  • H & S Services Limited (or Ltd);
  • @H & S Limited (or Ltd);
  • Hands: Limited (or Ltd);
  • # H & S Limited (or Ltd);

Similarly, if 'Catering Limited' is already a registered company we would reject the following applications unless the application is for a company in the same group as "Catering Limited" and Catering Limited has given its consent:

  • Catering UK Limited (or Ltd);
  • Catering.co.uk Limited (or Ltd);
  • Catering International Limited (or Ltd)
  • Catering Company (Services) Limited (or Ltd);

Which names need approval?

You will need the Secretary of State's prior approval if your chosen name:

  • suggests a connection with Her Majesty’s Government or a devolved administration or a local authority or a specified public authority (see chapter 3 and Appendices A & B);
  • a sensitive word or expression (see chapter 3 and Appendices A & B).

In the case of any name that requires approval because of the connection it suggests and also in the case of a name that includes certain sensitive words or expressions, you must request the specified Government department or body to indicate whether (and if so why) it has any objection to the proposed name. The 'Application to register a company (Form IN01)' includes a section requiring you to confirm you have sought the comments of the appropriate body. You must also deliver a copy of any response received and other supporting information with your application. Companies House will then consider whether to approve the name on behalf of the Secretary of State.

What types of words and expressions are sensitive?

The following words imply national or international pre-eminence:

  • British: You would need to show that the company is pre-eminent in its field by providing supporting evidence from an independent source such as a government department, trade association or other representative body.

    The level of pre-eminence in a name that includes 'British' depends on the impact created by the other words in the name. Usually the sense of pre-eminence reduces if the overall name does not describe a product, but you would still have to show that your company is substantial in its field even if this was not described in the company name.
  • National: The criteria for use of this word is the same as for 'British.'
  • England, English, Scotland, Scottish, Wales, Welsh, Ireland or Irish: : If one of these words appears as the prefix to a name, the requirements are similar to those for 'British'. If you intend to use, for example, 'of England' in the name this could also imply pre-eminence in the field.

    If you intend to use one of these words in the middle of a name or as the last word in a name this would normally be acceptable provided you can demonstrate that the company has its main place of business in the country concerned. If you want to use one of these words because it is a surname, you will usually be given approval if the company name includes forenames or initials.
  • Great Britain or United Kingdom: If you wish to use these expressions at the start of a name or if you intend to use 'of Great Britain' or 'of the United Kingdom' at the end of the name, the requirements are similar to those for 'British'. Using the initials 'GB' or 'UK' in your company name does not require approval.
  • European: We will not approve names which include this word if they unjustifiably imply a connection with official bodies of the European Union. If there is a genuine connection with an official body, we may allow the name if the appropriate body provides written support for the application.
  • International: If you wish to use this word as the first word in a name, you need to show that the major part of the company's activities is in trading overseas. If you wish to use it anywhere else in the name we will usually approve it if you can show that the company operates in two or more overseas countries.

The following words imply business pre-eminence or representative or authoritative status:

  • Association, Federation or Society: If you wish to use one of these words, your company must normally be limited by guarantee. Each member should have one vote and the constitution should contain a non-profit distribution clause. This provides that the company must use any profits to further the objects of the company and not pay them to the members as dividends.
  • Authority, Board or Council: If you want to use any of these words, you should contact Companies House Cardiff, Edinburgh, or Belfast depending on where the company is to be incorporated.
  • Institute or Institution: We normally only approve these words for those organisations which are carrying out research at the highest level or to professional bodies of the highest standing. You will need to show us that there is a need for the proposed institute and that it has appropriate regulations or examination standards. You will need evidence of support from other representative and independent bodies.
  • Government: We will only grant approval for the use of this word in a name if we are satisfied it does not give the impression that the company is connected with Her Majesty's Government, any part of the Scottish or Welsh administrations, or any overseas government. We will take the whole company name into consideration and judge it on its own merits.
  • HSC or HPSS: These stand for Health and Social Care and Health and Personal Social Services. We may consult DHSSPS (Department of Health, Social Services and Public Safety) when considering the approval of names containing this word as it could foster a misleading impression among patients, service users and wider public that the business enjoys an approved status in connection with the Health and Social Care or Personal Social Services.

The following words imply specific objects or functions:

  • Assurance, Assurer, Insurance, Insurer, Re-Assurance, Re-Assurer, Re-insurance or Re-insurer: If the name is for an underwriting company, we will normally seek further advice. However, if you want to use the name for a company that will only provide insurance services, you should include the appropriate qualification, for example 'agents', 'consultants' or 'services', in the name.
  • Benevolent, Foundation or Fund: We will not approve names that include any of these words if they unjustifiably give the impression that the company has charitable status. If the company is limited by guarantee and has a non-profit distribution clause in the memorandum of association, we will normally approve the name.
  • Charter or Chartered: We will not approve names that include these words if they unjustifiably give the impression that the company has a Royal Charter. If you use the words to qualify a profession, we will seek the advice of the appropriate governing body before considering whether to give approval.
  • Charity or Charitable: To use these words the company must provide a letter of non-objection from the 'Charity Commission' or 'The Office of the Scottish Charity Regulator (OSCR)'. If the company is not intended to be a charity, you must send a copy of the proposed memorandum and articles of association along with details of the company activities and an explanation of why the word is required to the Charity Commission or the OSCR.
  • Chemist or Chemistry: If you want to use these words, you should ask for advice from Companies House in Cardiff , Edinburgh or Belfast as appropriate.
  • Co-operative: If you wish to use this word, your company's Articles of Association should follow the rules generally associated with co-operatives in the UK. If you need further advice you should contact Companies House in Cardiff, Edinburgh or Belfast as appropriate.
  • Friendly Society or Industrial and Provident Society: We will refer names which include these expressions to the Registrar of Friendly Societies for advice. If you need further advice you should contact Companies House in Cardiff, Edinburgh or Belfast as appropriate.
  • Group: : If use of this word implies several companies under one corporate ownership, you will need to provide evidence of a parent and/or subsidiary association with two or more other British or overseas companies. If the name clearly shows that the company is to promote the interests of a group of individuals, then the name will normally be approved.
  • Holding(s): A company wishing to use this word must be a holding company as defined under section 1159 (2) of the Companies Act 2006.
  • Patent or Patentee We will only approve a name including either word if it does not infringe the Copyright, Designs and Patent Act 1988.
  • Post Office: These words are registered trade marks of the Royal Mail group and we will seek advice on applications that include these words.
  • Register or Registered We treat every application for use of these words on its merits. Generally, we will seek advice from the appropriate governing body if names that include these words relate to a professional qualification. We will not register the name if it unjustifiably implies a connection with Her Majesty's Government or a local authority. If there is a connection we will register the name if the appropriate body supports the application.
  • Sheffield: If you wish to use a name that includes the word 'Sheffield', we will need to establish details of the company's location and its business activities. We will also consult the Company of Cutlers in Hallamshire.
  • Stock Exchange: We will not approve names including this expression unless there are special circumstances.
  • Trade Union: We will not approve names including this expression unless they conform to legislation relating to trade unions.
  • Trust: The word 'trust' can be used to suit a range of different situations and the requirements for such trusts are explained below:
    • Charitable Trust - these companies need to have charitable objects and a non-profit distribution clause in the Articles of Association. We will ask you for confirmation that you have made, or will make, an application for registration as a charity with the Charity Commission. Scottish companies wishing to use the expression 'charitable trust' will need to apply to Her Majesty's Revenue & Customs (HMRC) in Edinburgh as the Charity Commission has no jurisdiction in Scotland.
    • Educational trust or Artistic Trust - such companies should have a non-profit distribution clause in the Articles of Association and the name should reflect the nature of the trust. The promoters should be of high standing in the field.
    • Enterprise Trust - these companies must have a non-profit distribution clause in the Articles of Association and they must be able to provide evidence of support from, for example, local authorities, businesses or banks.
    • Family Trust - such companies must be non-profit distributing and the objects must reflect the nature of the trust. Names of family trusts will usually be approved if the name as a whole identifies the company as a family trust.
  • Financial Trust or Investment Trust - if you wish to use these expressions, you will need to provide a written assurance that substantial paid-up share capital or other funds will be achieved within a reasonable period after incorporation.
  • Pensions or Staff Trust - the names of such companies must include the name of the parent company, and the objects of the company must include the operation of pension funds.
  • Unit Trust - if you wish to use this as part of your company name, you should seek the advice of Companies House in Cardiff or if the company is to be registered in Scotland, Companies House in Edinburgh.

Objections to company names

Could I have to change my company name after incorporation?

In general, a company can keep its registered name for ever. However a company can be required to change its name:

  • within 12 months of the adoption of the name, if the Secretary of State upholds an objection that a newly-adopted name is "too like" an already existing name or if the name was incorrectly registered because it is the 'same as' an existing company name. Any objection must be made in writing within 12 months of the date of the registration of the name. If such an objection is upheld, then the company must change its name as directed and deliver the required documents within 12 weeks of the date of the direction. Further information on 'too like' names is provided in question 3;
  • within 5 years of the company's adoption of the name, if misleading information has been given for the purposes of registration by a particular name for example for the approval of a sensitive name;
  • within 5 years of the company's adoption of the name, if an undertaking or assurance given at the time of registration, for example support for a sensitive name has not been fulfilled;
  • at any time, if the Company Names Adjudicator upholds an objection that the name is the same as one in which the objector has goodwill or is so similar to such a name that its use in the UK would be likely to suggest a connection between the company and the objector. Such an objection will be upheld if the objector shows that the main purpose in registering the name was to obtain money or other consideration from him or to prevent his registering the name. (It may also be upheld if none of certain other matters have happened or apply).
  • at any time, if the name gives so misleading an indication of the nature of its activities that it is likely to cause harm to the public;
  • at any time, if a company is no longer entitled to the exemption allowing it to omit "limited" or any of the permitted alternatives in its name.

What does 'too like' mean?

Any company that registers a name which is very similar ('too like') to an existing company name could be directed to change its name. When considering whether one company name is 'too like' an existing company name Companies House only considers the visible appearance or sound of the two names. We do not take into account external factors such as geographic location, trading activities, share ownership or whether a company is dormant. In addition we take no account of a name or part of a name that is a registered trade mark.

Normally, if the names differ by only a few characters or minor differences they are likely to be 'too like', for example, H & S Consultants Limited and H & S Consulting Limited. Most examples of 'too like' names also suggest a certain level of confusion.

If the names differ by one or more words, especially longer descriptive words they are unlikely to be 'too like'. For example, an existing company, H & S Consultants Limited might justifiably complain that the registration of H & S Consultants (Cardiff) Limited is a cause of confusion. This might be the case but the names are not 'too like' under the Companies Act and we would be unlikely to issue a direction in these circumstances.

However, we would issue a direction if the names have substantial or very distinctive elements in common and differ only by the inclusion of meaning starved words such as "services" or "trading".

How are 'too like'objections dealt with?

We must receive objections within 12 months of a company's incorporation (or change of name). If following an objection, we intend to direct a company to change its name we will write to the company to explain the nature of the objection and the limited scope for appeal. We will also inform the complainant of the action taken. If we reject the company's appeal we will issue a direction requiring it to change its name within 12 weeks and also inform the complainant. If we accept the company's appeal we will confirm this in writing to all parties.

Can Companies House reject a 'too like' name when a company files its application to register a company?

No. You can only make objections on grounds of 'too like' after Companies House has registered the company. We can only reject 'same as' names before registration. Not all potentially 'too like' names result in an objection.

To avoid the possibility of a 'too like' objection, we advise applicants to make a search of the Index of Company Names before they apply to form a company or change the name of an existing company. Having a 'too like' name could also result in:

  • confusion with other companies, which may have a poor filing or trading record;
  • a 'passing off' action under civil law; or
  • action for trade mark infringement

We do not consult the Trade Marks Register when considering an application for a company name. Consequently, if there is a trade mark registration which is identical or similar to the company name you have chosen and you are in the same type of business you may face legal action for a trade mark infringement. For further advice, including how to search the trade marks register, contact the UK Intellectual Property at http://www.ipo.gov.uk

Objection on grounds of opportunistic registration

Any individual or company can apply to the Company Names Tribunal for a company to be directed to change its name if they can show that the name was chosen with the principal intention of seeking money from him or preventing him registering the name where it is one in which he has previously acquired reputation or goodwill.

The Company Names Tribunal (also known as the 'Company Names Adjudicator') is responsible for handling complaints about opportunistic registration. Further information, including application forms and contact information is available on their website. Please note, Companies House cannot deal with any complaints about opportunistic registration.
