What is Companies House? The Complete Guide to UK Business Registration

For any entrepreneur or business enthusiast in the United Kingdom, the name Companies House is more than just a government department—it is the cornerstone of the UK’s corporate ecosystem. Whether you are launching a tech startup in London, a consultancy in Edinburgh, or a manufacturing firm in Belfast, your journey officially begins and ends with this institution.

In 2026, the role of Companies House has evolved significantly. Following the landmark reforms of the Economic Crime and Corporate Transparency Act (ECCTA), the registrar has transformed from a passive library of data into an active gatekeeper of the UK’s economic integrity.

This comprehensive guide explores the functions, locations, legal responsibilities, and digital services of Companies House, providing a deep dive into what business owners must know to thrive in today’s transparent corporate landscape.

What Is Companies House?

Quite simply, Companies House is the official registrar of limited companies in the United Kingdom. It operates as an executive agency of the Department for Business and Trade (DBT).

The Core Remit

The primary mission of Companies House is to incorporate and dissolve limited companies. This includes various legal structures, such as:

Private Limited Companies (Ltd)

Public Limited Companies (PLC)

Limited Liability Partnerships (LLP)

Limited Partnerships (LP)

Community Interest Companies (CIC)

All activities are governed by the Companies Act 2006, which serves as the primary legislation for company registration and management in England & Wales, Scotland, and Northern Ireland.

The 2026 Evolution: From "Library" to "Gatekeeper"

Historically, Companies House was often described as a "repository"—it accepted information on a trust basis and made it public. However, since 2024, its powers have expanded. Today, the registrar has the authority to:

Query Information: They can challenge and reject filings that appear suspicious or inaccurate.

Verify Identities: All company directors and "People with Significant Control" (PSCs) must now undergo mandatory identity verification.

Enforce Compliance: They can issue significant financial penalties and strike off non-compliant companies without a court order.

Where Is Companies House Based?

Companies House is a large organization employing over 1,000 staff members. Because the UK operates under three distinct legal systems—English Law, Scots Law, and Northern Irish Law—the registrar maintains specific offices for each jurisdiction.

Regional Office Breakdown

The location of your company’s registered office address determines which branch handles your incorporation:

Note: While your company can trade anywhere in the UK or internationally, your registered office address must remain within the country of incorporation (e.g., a Scottish company must maintain a registered office in Scotland).

What Information Is Stored on the Public Register?

Transparency is the heartbeat of Companies House. The registrar advocates for a culture where information is accessible to the public, government bodies, and financial institutions to foster trust in the economy.

Key Data Held on Record:

Company Basics: Name, registration number, and date of incorporation.

Status: Whether the company is "Active," "Liquidation," or "Dissolved."

Officers: Full names and service addresses of directors and secretaries.

Ownership: Details of shareholders and People with Significant Control (PSCs).

Financial Health: Annual accounts (Balance Sheets, Profit & Loss) and mortgage charges.

Compliance History: Confirmation statements and records of late filings.

Insolvency: Details of any winding-up orders or administrations.

Why This Data Matters

This information isn't just for curiosity; it serves vital economic functions:

For Banks: To perform "Know Your Customer" (KYC) checks before opening business accounts.

For Competitors: To research market share and industry trends.

For Law Enforcement: To prevent money laundering, fraud, and terrorism financing.

For Consumers: To verify that a business is a legitimate legal entity before making a purchase.

Key Digital Services and Filing Tools

In 2026, almost all interactions with Companies House are digital. The agency has invested heavily in software to make compliance "seamless."

1. The Companies House Service (CHS)

This is a free search tool that allows anyone to look up company information. You can view filing histories, download copies of accounts, and even set up email alerts to follow a specific company’s activity.

2. WebFiling

WebFiling is the secure portal used by directors to submit their annual documents. Using this service ensures:

Speed: Documents are processed much faster than paper filings.

Reminders: You can sign up for alerts to ensure you never miss a deadline.

Accuracy: Built-in validation checks help reduce the risk of rejection.

3. Identity Verification Portal

A newer addition to the digital suite, this allows directors to verify their identity using GOV.UK One Login or through an Authorised Corporate Service Provider (ACSP).

Compliance: Your Legal Obligations

Running a limited company comes with "statutory obligations." Failure to meet these can lead to director disqualification or criminal prosecution.

The Annual Confirmation Statement

At least once a year, you must file a Confirmation Statement. This isn't about finances; it’s a snapshot to confirm that the information Companies House holds (address, directors, shareholders) is still correct.

Filing Annual Accounts

Every company must prepare and file annual accounts. In 2026, the rules for "small" and "micro-entities" have tightened. Most companies are now required to file a full Profit and Loss account to ensure greater transparency.

Keeping Records Updated

You must inform Companies House within 14 days if:

You appoint or remove a director.

A director changes their home address or service address.

The company changes its registered office.

There is a change in the PSC register.

Companies House vs. HMRC: Understanding the Difference

A common mistake for new business owners is confusing Companies House with HM Revenue & Customs (HMRC).

Companies House is concerned with existence and transparency. It wants to know who you are and where you are. All its data is public.

HMRC is concerned with taxation. It wants to know how much you earned. Its data is private.

While you might file your accounts to both, they serve different masters. If you tell Companies House about a change of address, you must usually tell HMRC separately!

Strategic Importance for the UK Economy

Companies House is more than a database; it is a tool for economic growth. By providing reliable data, it allows international investors to make informed decisions about moving capital into the UK. The recent shift toward stricter verification has only enhanced the UK’s reputation as a "clean" place to do business, free from the shadow of shell companies and financial opacity.

Questions Clients Commonly Ask

1. Can I register a company if I don't live in the UK?

Yes, you can be a director of a UK company without being a UK resident. However, you must provide a UK-registered office address for the company and complete the mandatory identity verification.

2. What is a "Person with Significant Control" (PSC)?

A PSC is usually someone who owns more than 25% of the shares or voting rights in a company, or who has significant influence over its management.

3. What happens if I file my accounts late?

Companies House imposes automatic civil penalties for late filing, starting at £150 and rising to £1,500 for private companies. If you are late two years in a row, the fines double.

The Standard Industrial Classification code describes what your business does (e.g., "62012 - Business and domestic software development").

12. What is a "Confirmation Statement"?

It is a yearly filing that confirms the company's administrative details (address, officers, shareholders) are up to date.

13. What is the "Lawful Purpose" statement?

When incorporating or filing an annual statement, directors must now confirm that the company’s intended activities are lawful.

14. Can I change my company name?

Yes, you can file a "Change of Name" notice, provided the new name isn't already taken or deemed offensive/sensitive by the registrar.

Your CRN is an 8-digit number (or 2 letters followed by 6 digits) found on your Certificate of Incorporation and at the top of your company's page on the Companies House search service.
