How to choose a name for your business

If your business is a private company limited by shares and guarantee its name must also:

• end with 'limited' or 'Ltd' (if the company is registered in Wales, the Welsh equivalents, ‘Cyfyngedig’ and ‘Cyf’, can be used)

• not be the 'same as' the name of an existing company

If your business is a limited liability partnership (LLP), its name must also:

• end with ‘limited liability partnership’ or ‘LLP’ (if the LLP is registered in Wales, the Welsh equivalents, ‘Partneriaeth Atebolrwydd Cyfyngedig’ or ‘PAC’, can be used) 

• not be the 'same as' the name of an existing business

If you are operating a partnership or as a sole trader, your business name must also not include ‘limited’, ‘Ltd’, ‘limited liability partnership, ‘LLP’, ‘public limited company’ or ‘plc’.

The Competition and Markets Authority (formerly the Office of Fair Trading) warns firms against misleading clients about the services on offer, the costs, the geographic scope of the business or the relationship with other businesses.

You can also carry on business in the UK using a ‘trading name’. If you choose to do so, when entering into business contracts or on official paperwork, you can use your name, followed by the wording ‘trading as’ before your business name.

For more information, see the Government’s guidance on choosing a company, LLP, partnership or sole trader name.

If you have a website, it’s equally important to be able to secure a domain name (ie the electronic address for a website address) that may be the same as or very similar to your business name. This will come with a suffix (eg '.co.uk' or '.com'). The domain name combined with the suffix is known as the URL.

Typing your preferred URL into the bar at the top of your web browser will quickly reveal whether a website with that domain name and suffix exists. If it does, you may want to consider a different name or suffix.

If you Google your preferred business name, the results could reveal some adverse publicity about another business with a similar name which might make you reconsider using it.

A more thorough check can be carried out using one of the many domain name registration companies. If the specific name is not available you could try some alternative domains which may still be suitable for your business (eg a '.co.uk' instead of a '.com'), but note:

• this could indicate there is an existing business with your preferred name or something similar which might object to you adopting your preferred name (particularly if you intend to provide similar goods or services), and
• domains ending with '.ltd.uk' are reserved for private limited companies registered at Companies House

You can register your domain name through accredited domain name registrars who manage the reservation of domain names. Typically a registration will be for one or two years. It is important to ensure you keep renewing your domain name registration – if it is allowed to lapse, the domain name could be registered by someone else.
