If you are setting up a limited company, you should think carefully when choosing your company name. Alongside the business reasons for choosing an appropriate name, there are also a number of official company naming rules you should be aware of.
If you fall foul of the official company naming guidelines, Companies House will simply reject your company formation application.
Company naming rules
Here is an overview of the main rules you need to be aware of when deciding on the name for your new company.
Each company name must be unique
Each company name must be unique. When buying a limited company online, the registration agent (or, more likely, the automated software) will be able to tell you if your chosen name is available or not.
You can conduct a simple online search with our Company Formations Partner to establish whether the name you would like to use for your new company is available.
You can change your company name at a later date, but you cannot change the company registration number which will be allocated by Companies House when you form a company.
Each private limited company name must include a ‘Limited’ or ‘Ltd’ suffix (such as Bytestart Limited). If your company’s registered office address is in Wales you can choose to use the Welsh suffix “cyfyngedig” or “cyf”.
Words and terms you cannot use
You cannot use so-called ‘sensitive’ words unless you have received official permission. You can read a detailed list of these sensitive words in the Companies House Guide to incorporation and names.
You should not choose an ‘offensive’, ‘abusive’, or ‘illegal’ company name. Not only would that be an odd thing to do for obvious business reasons, but your choice could also be rejected.
Your company is a legal entity, but you can carry on business using a different name if you choose.
Don’t choose a name that contains trademarked words, or words deliberately used to resemble them. You may have trouble later on if you do so.
To make sure you avoid trademarked names when naming your limited company you should check the UK’s Intellectual Property Office’s Trade Mark Register.
Once you form a limited company, your name will be protected by Companies House. No other applicants can choose a name that is too similar to yours.
Matching domain name
It’s not a requirement, but it’s definitely a good idea to try to secure a matching domain name for your new company name. This will provide you with seamless branding, and an email address to match your company name.
Alongside the .co.uk domain name suffix, we would also recommend you try to secure the .com domain as well, to protect your online identity.
With fierce competition for short, snappy domain names, there has been a trend in recent years for business owners to find a suitable domain name first, and then name their company after their preferred web address.
If your business is going to have a significant online presence, this is a good idea.
