What Is A Company Registration Number

A company registration number is a unique identifier assigned to a business by Companies House that identifies the company and its legal status. The number is used for various administrative purposes, such as filing annual returns and maintaining company records, and consists of a series of digits, usually seven or eight in length with the first two or three digits usually identifying the country that the business is registered in.

Do All Companies Need A Registration Number?

Before a limited company business can operate in the United Kingdom, it must first register with Companies House. This is the government body responsible for incorporating and dissolving limited companies and maintaining statutory records of company ownership and directors. Companies House also issues certificates of good standing, which are required for businesses to tender for public sector contracts.

Whether your business needs a registration number or not will depend on the company formation type you choose. Sole traders and the self-employed do not need to register their business with Companies House as they are legally the same entity, but they will have other types of unique identifiers, such as a Unique Taxpayer Reference (UTR). This is used to pay income tax and National Insurance on their earnings after completing a Self Assessment Tax Return.

All other types of companies in England and Wales must be registered with Companies House. This includes private limited companies, public limited companies, limited liability partnerships, and other types of businesses regardless of business size and turnover, including those who want to publicly list shares and register for VAT are required to register their business in the UK.

Limited Company Business Structure Overview

Limited Company Business Structure Overview

There are four types of business structures that need to register with Companies House: private companies limited by shares, private companies limited by guarantee, public limited companies, and unlimited companies.

Each type of company has different requirements for registration, so it is important to check the relevant legislation before applying, and a brief overview of each structure is included below.

What Are Private Companies Limited By Shares?

A private company limited by shares is the most common type of business entity in the United Kingdom. This type of company is ‘limited’ because it has shareholders who have limited liability for the debts of the company. The shares are issued to raise capital for the company and can be traded on a stock exchange or sold privately.

What Are Private Companies Limited By Guarantee?

A private company limited by guarantee is a type of company often used by charities, clubs, and associations. The members of the company agree to pay a fixed amount (the ‘guarantee’) if the company is wound up.

What Are Public Limited Companies?

A public limited company (PLC) can offer shares to the public and is usually quoted on a stock exchange. A PLC must have a minimum share capital of £50,000 and must meet certain other conditions set out in the Companies Act 2006.

What Are Unlimited Companies?

An unlimited company does not have shareholders but may have members who have ‘unlimited liability’. This means that they are liable for the debts of the company if it cannot pay its creditors.

Unlimited companies are relatively rare and are usually only used by businesses that want to avoid the restrictions that apply to other types of companies.

Benefits To Limited Company Structures

Benefits of setting up a limited company, include;

  • Limited liability: shareholders are only liable for the amount of money they have invested in the company. This protects them from being held responsible for the debts of the company if it cannot pay its creditors.
  • Flexibility: a limited company can be set up with different types of share structures to suit the needs of the business.
  • Tax efficiency: a limited company can claim certain tax reliefs and allowances that are not available to other types of business.
  • Status: a limited company may be seen as more professional than a sole trader or partnership.

Drawbacks To Limited Company Structures

Drawbacks to setting up a limited company include;

  • Complexity: a limited company is more complex to set up and run than a sole trader or partnership. There are more legal and financial obligations that need to be met.
  • Cost: a limited company costs more to set up than a sole trader or partnership.
  • Bureaucracy: a limited company is subject to more regulation than a sole trader or partnership. This can be seen as a disadvantage as it can be time-consuming and costly to comply with all the requirements.
If you work with a company formation agent when setting up your business, they will ensure that you choose the right business structure, can assist with the incorporation of the company, and help to register it with HMRC. This ensures that you register the business correctly and obtain the necessary licenses and permits for your area of work and can be a great professional help in the set up of a new company.

Companies must file annual returns with Companies House to keep their registration up to date. Failure to do so can result in significant penalties so it is essential for all businesses operating in the UK to ensure that they are properly updating their registration documents.

  • Changing the name of your company or limited liability partnership
  • Changing your registered office address or SAIL address
  • Appointing and removing a company secretary
  • Appointing and removing limited liability partnership members
  • Changing your accounting reference date (ARD)

If you can’t find these documents, you can use the public register to search the Companies House’s records by company name to find your company registration number. Your registration number can also be found on various documents, including the company’s articles of association, shareholder certificates, annual returns, VAT Returns, and account filings, plus it is often listed on company websites and marketing materials, including headed paper because limited companies and LLPs are legally required to display their CRN on all forms of official business stationery.

If you are unsure where to find your company’s registration number, you can contact Companies House, the government agency responsible for maintaining records of all businesses in the UK.

Can You Make Changes And Does The Registration Expire?

Your company registration number is assigned to you when you first register your business and is used for official purposes, such as filing annual accounts and complying with tax obligations. It can be changed in certain circumstances but it doesn’t expire until you officially register your business as closed with Companies House.

For example, if you’re changing the name of your business or merging with another company, you’ll need to update your registration number to reflect the new name or structure. In most cases, only the registered office address and director details need to be updated with Companies House; the registration number will be automatically updated.

You can also change your registration number if it’s been compromised in some way – for example, if it’s been made public without your permission. In these cases, you’ll need to contact Companies House (the government agency responsible for issuing registration numbers) and request a new number.

If you need to change your company registration number for any other reason, you can do so by contacting Companies House directly and they will action your request. It’s important to note that changing your company registration number won’t affect any of your existing contracts or agreements but it’s always a good idea to update your registered address and contact details with Companies House so that other businesses and organsations can easily get in touch with you.
