Initial thoughts on change company name

When considering a new business name, we must amend it with an official government body. In the UK, the Registrar of Companies (also known as Companies) are a body that looks after company formation procedures. What’s more, they look after the UK public register. This contains a list of all companies with their respective limited company names. Basically, this register of Companies House names includes some basic details about all UK limited companies. However, the official record must be updated when you amend the business name. As a result, the new information of such a recent company change is recorded officially. Therefore, as the register includes all company names, a business owner should inform the UK public body when they make a company name change (Companies House).

Every UK company has a name and a company number. Basically, this number will stay the same during the company’s existence. However, the owner can modify the business name anytime. Therefore, what should we consider when investigating how to amend your business name? Besides checking for UK company name availability, there’s a form to file with Companies House. This form is required when businesses amend Companies House company names (UK). In addition, when we ask can you change a company name online, the same form is required. Therefore, you can file this either online or through the postal system. To sum up, many limited company contractors and small business owners let their accountants amend the Companies House business name on their behalf. Others who don’t have an accountant can ask a formation agent to make the amendment.

What to consider when you change a company name on Companies House? 

The initial considerations when you change company name

As a UK contractor or small business owner, you must choose a registered office besides your business name when setting up your company. However, at some point during your contracting career, you may research how to change the name of a Limited company for one reason or another. As a result, you should know how to amend the name of a private limited company. Alternatively, you could ask your accountant to do this.

When might you investigate changing company name?

At some point, when you run your own UK company, you may decide the time has come to choose a new business name. Indeed, when you change company name, it could be for several reasons. You may feel the name is no longer appropriate for your current line of work. Alternatively, you may decide the current business name is no longer suitable for the type of professional services you’re now offering. Therefore, you must investigate how to amend my company name.

Other tasks to consider when you change company name

Besides investigating how to change a company name (UK) with Companies House, there are other tasks to perform when amending a limited company name. Please see later in this guide for our business name change checklist of what else to do when you switch your business name.

Companies House -check company name 

Before you amend your company’s name, you can do a Companies House company name check. You can perform the Companies House business name check (UK) by visiting the Companies House website. Next, you can type the name in the search box and click the search icon to check Companies House for names. As a result, you can perform a UK company name search, or check a limited company name. Consequently, you’ll discover if your proposed new name choice is available before you apply to change company name. However, when you check Ltd company names, if any already registered company names (UK) are in use by other companies, you can’t use them. Therefore, if a name is taken, you can repeat the process and check Companies House for available names based on what you’re considering for potential new contractor company names.

Please note, when you look for available company names (UK) and perform the limited company name check (Companies House), you shouldn’t choose a UK contractor company name that’s the same or similar to another company. If you do, Companies House may reject your request. In addition, as part of the UK company name change, your business must receive the required permission to include sensitive words and expressions. These words include ‘international’, ‘bank,’ and `certified.’ 

Other guides

Besides this guide on how to change the company name (Companies House), we’ve many other Companies House guides.

Moreover, these explain what this public body is and how to make a particular amendment and report this correctly. We’ve covered the following in our guides:

How to change company name on Companies House -what is the process? 

Initial steps

Let’s look at how to change my company name at Companies House officially. In larger businesses, company secretaries will initiate the process of amending this. However, as a small contractor company, you’ll make the amendment yourself or ask your accountant to do this. In addition, some larger companies may have to consider any trademark implications of an amendment to their business name.

The process of amending the limited company’s name is straightforward enough. Moreover, when we look at the official process of amending a contractor’s company name, the most common way is to pass a special written resolution at a general meeting. This is a formal decision that at least 75% of the company’s members votes agree to. The special resolution can be passed in writing or in a general meeting to approve the change.

When you apply to change company name, you must complete Companies House form NM01 -notice of name change by resolution. Indeed, the Companies House change of name form is used by UK limited companies to give notice to Companies House of a written resolution on amendment of the business name. Therefore, you can complete the Companies House NM01 form and change company name online. As an alternative, you can send a completed form through the post. Either way, it will ensure the Companies House registers are updated correctly.

We have a separate guide that covers choosing a name for your UK company. Selecting a business name is relevant when forming your company for the first time.

What is the cost & how long does it take to change company name?

When you amend the business name, what’s the cost of changing company name, and how long does a name change take (UK)? Indeed, when changing the business name, the first option is to submit a paper NM01 form to Companies House. As part of making a postal application, the fee for the change of name form (Companies House) is £30. Moreover, when you complete the form NM01 (Companies House), you can pay by cheque or Postal Order. In addition, you can send the NM01 and payment to the address on the form.

On the other hand, the more popular option is to amend your business name via Companies House online. Indeed, you can change company name by filing the NM01 form online via their WebFiling service. When you use this method, the Companies House fee is £20. Moreover, there’s an alternative cost of £83 for an NM01 same-day name change (Companies House). Therefore, the same-day service is preferable if you’re in a rush for the name amendment. However, most will use the £20 company name change service.

If you use the £20 service, the Companies House change name process will take a day or two. Furthermore, the process is complete once Companies House approves it. In summary, most UK contractors and small businesses will use the online service when making the amendment.

Complete forms to change the Ltd company name

The Companies Act 2006 (sections 77-79) allows a company to amend its name by:

  • Passing a special resolution of the members, or
  • By other means, provided for in the articles of association.

When you’re amending a limited company name, the company can pass the special resolution at a board meeting. Therefore, if you’re a limited company contractor with your own company, you can hold a director’s general meeting, and the shareholders can sign a written special resolution. However, your Articles of Association may define another method to do this.

After you pass the resolution, you can submit the NM01 with the correct fee to Companies House. Indeed, they’ll process the business name amendment within a working day or two.

If you’re to change company name via the second method above, as defined in your company’s Articles of Association (this isn’t likely if you’re the owner of a contractor limited company), you can use form NM04.

Once you’ve sent the change of name (Companies House) form through the post or filed online and the Registrar of Companies have processed the amendment, you’ll receive a Certificate of Incorporation on Change of Name.
