Company and business names

This guidance is for England, Scotland and Wales

Requirements for the use, display and disclosure of company, business and trading names are detailed in four pieces of legislation:

• Companies Act 2006
• Limited Liability Partnerships (Application of Companies Act 2006) Regulations 2009
• Company, Limited Liability Partnership and Business Names (Sensitive Words and Expressions) Regulations 2014
• Company, Limited Liability Partnership and Business (Names and Trading Disclosures) Regulations 2015

There are requirements relating to the name that a business chooses to trade under and rules to prevent the use of names that could mislead the public.

Who do the business names provisions apply to?

This legislation gives detailed requirements regarding names that businesses can choose to trade under and how particular details about businesses have to be disclosed to their customers. The provisions apply to:

• individuals who trade under a name that is not their own
• partnerships that do not operate under the names of the individual partners
• companies / limited liability partnerships

Sole traders and partnerships

Sole traders and partnerships that are not registered companies are required to display and disclose detailed information about their businesses when they use a business name that is not their surname (with or without forenames or initials) or one that does not use the names of all the partners.

For example, if John Smith has a shop called Happy Family Bakers, the disclosure requirements would apply to him; were he to call his business Mr Smith, John Smith, or J Smith, they would not. The same would apply to a partnership. If John Smith and Sarah Jones have a business partnership called Happy Bakers, the disclosure requirements would apply; were they to call their business J Smith and S Jones, or Smith and Jones, they would not.

As well as the above, the disclosure requirements do not apply when a business is continuing the trade of a former owner, and the new name includes both the former and current owners - for example, 'Mr Smith (formerly Ms Jones)'.

Business names display

Where a sole trader or partnership carries on business under a name that is not that of the proprietor or partners their details must be fully disclosed to customers and suppliers in order to make it clear who they are doing business with.

The following information is required to be disclosed:

• full name of the proprietor or all of the partners
• an address at which the business can be contacted and have legal documents formally served on it

The required information must be:

• displayed in a prominent position in all business premises where customers and suppliers have access
• included legibly on all business documents:
  • letters
  • written orders for goods or services
  • invoices and receipts
  • written demands for payment
  • business websites (a requirement under the Electronic Commerce (EC Directive) Regulations 2002)
• given immediately in writing to any customer or supplier who requests business details information

Partnerships of more than 20 persons are not required to disclose details all of the partners in business documents if:

• a list of the names of all the partners is maintained at the principal place of business
• none of the partner's names appear in documents except in the text or as a signatory
• documents state legibly the address of the partnership's principal place of business and that the list of the partners' names is open to inspection there
• the list of the partners' names is available for inspection during office hours

Below is an example of a notice that could be displayed to comply with the business premises requirements for a sole trader. Partnerships need to include the full names of all of the partners in such a notice.

Companies

The following requirements apply only to companies that are registered with Companies House.

Rules on company names

Other requirements

The following applies equally to sole traders, partnerships, companies and LLPs.

Trading names and trade marks

Whether you have a business, partnership or company, you may well wish to trade under a different name. If you do, you need to be aware that you cannot use another company's trade mark as your business name. You can search the trade mark register on the GOV.UK website to find out if a mark is already registered.

If someone else begins to trade using your trade name or your unregistered trade mark you may have to take an action for 'passing off' in the civil courts to stop them. Therefore, you may wish to register your trade name or unregistered trade mark for enhanced protection.

To be registered, trade marks must comply with the rules relating to trade mark registration and certain names or marks are not eligible for registration - for example, marks that include common trade terms, such as A1 Taxis, A1 Cleaners, etc. However, this does not prevent anyone carrying on a business under those names. To register a trade mark you can apply online to the Intellectual Property Office (IPO).

See 'Intellectual property' for more information on trade marks.

Distance sales

Also applicable to any business that trades through advertisements or online are the Consumer Contracts (Information, Cancellation and Additional Charges) Regulations 2013. These Regulations require a supplier to provide a prospective buyer with details about themselves. Before a consumer concludes an online transaction or responds to an advert etc the supplier must provide details of the postal address of their business, so that a consumer may address complaints in a durable written format.

The Electronic Commerce (EC Directive) Regulations 2002 require businesses selling or advertising online to provide certain information on their website, some of which overlaps with the above requirements, such as the company or business name, a UK geographic address and detailed information on pricing, delivery charges, etc.

See 'Consumer contracts: distance sales' for more information.

Trading Standards
