If you are going to start a business in the UK, you will first need to have a name for that business. Once you have come up with a name for your new UK business, you will have to register that name. Registering a business name in the UK is a fairly simple and straightforward process. In fact, one company handles all business name registrations for all of the UK.
See if your desired name is already taken. Look through the Company Names Index that Companies House maintains for all registered UK companies. If your desired name is already taken, check your backup names to see if they are available.
Make sure your desired name is legal. In the UK, business names with certain words or phrases have to be approved by the state. Any names that may mislead the public about the business size or affiliation fall under this category. Examples of this are businesses with any of the following words in the name: British, national, international, institution and government.
Check to see if your name conflicts with a trademark. You will need to check Trade Marks Register to see if your desired business name has a conflict with a registered trademark in the UK. You can check this with the Intellectual Property Office.
Register with Companies House. You can register your business name in the UK with Companies House, as it handles all business name registrations in the UK. You can get the form from the company's website and then mail it along with the £10 fee. Businesses in England and Wales you mail to Registrar at Companies House, Cardiff; companies in Scotland you mail to Registrar at Companies House, Edinburgh.
