How to Use Companies House Search: A Complete Data Guide

Company Formation and Compliance Specialist
The Companies House register is more than just a government database; it is a goldmine of transparency that keeps the UK business ecosystem functioning. Whether you are a business owner checking on a competitor, an investor performing due diligence, or a service provider verifying a potential client, knowing how to navigate this tool is essential. In this guide, you will learn how to access free company data, interpret complex filing histories, and use advanced search filters to find exactly what you need.
Navigating the Search Interface
The primary tool for most users is the Companies House Service (CHS). This digital platform replaced the older "WebCheck" system and offers a much more intuitive, mobile-friendly experience. When you land on the search page, you are presented with a simple search bar, but the power lies in how you use it.
Using Company Names and Numbers
Searching by name is the most common method. If you have the exact Company Registration Number (CRN), use that instead, as it is a unique identifier that eliminates confusion between companies with similar names. If you only have a partial name, the system will suggest matches as you type.
Search Filters and Scoping
Once you hit search, you can filter results by status. This is crucial if you only want to see Active companies rather than those that have been dissolved or are in liquidation. You can also filter by location (England and Wales, Scotland, or Northern Ireland) to narrow down regional entities.
- Use the Company Number for 100% accuracy in identification.
- Filter by "Active" to remove defunct businesses from your research.
- Check the "Previous Names" section if a company seems to have vanished.
- Utilize the "Officers" search to find every company linked to a specific individual.
Interpreting the Company Overview
The "Overview" tab is your snapshot of a company's health and legal standing. It provides the foundational data points that every researcher should check first. Understanding these fields helps you determine if a business is compliant with its statutory obligations.
Company Status and Type
The status will typically be "Active." However, look out for terms like "Active — proposal to strike off," which suggests the company may soon cease to exist, either voluntarily or via compulsory action by the Registrar. The company type will tell you if it is a Private Limited Company (Ltd), a Public Limited Company (PLC), or a Limited Liability Partnership (LLP).
Registered Office Address
This is the official address where legal correspondence is sent. It may not be the actual trading premises; many businesses use their accountant's office or a virtual office service to maintain privacy. Always cross-reference this with the company’s website to ensure consistency.
- Incorporation Date: Shows how long the business has been established.
- Nature of Business (SIC): The Standard Industrial Classification (SIC) code defines what the company actually does.
- Next Accounts Due: A critical indicator of whether the company is keeping up with financial reporting.
- Confirmation Statement: Indicates when the company last verified its internal structure with the Registrar.
Analyzing Filing History and Accounts
The "Filing History" tab is arguably the most valuable part of the register. It contains a chronological list of every document the company has ever filed. For those performing due diligence, this is where you find the "truth" behind the brand.
Full Accounts vs. Filleted Accounts
Small companies and micro-entities often file filleted accounts, which provide less detail than full accounts. While they might not show turnover, they still include a balance sheet. You can assess Net Assets and Current Liabilities to judge the firm's solvency. For larger firms, you can view the full Profit and Loss account.
The Confirmation Statement (CS)
Formerly known as the Annual Return, the Confirmation Statement lists changes in share capital, shareholder identities, and the registered office. If you want to know who really owns a company, this is the document to download. Learn more about these requirements in our guide to company filings.
- Download the Certificate of Incorporation to see the original formation details.
- Review Mortgage Charges (MR01) to see if the company has secured loans against its assets.
- Check for Change of Name filings to track the company's historical branding.
- Look for "Notice of dividends" or "Director appointments" to see internal movements.
People and Control: Directors and PSCs
A company is more than just a legal entity; it is run by people. The "People" tab allows you to see exactly who is steering the ship and who holds the ultimate power through the Register of Persons with Significant Control (PSC).
Officer Profiles
Each director has a profile. By clicking on a director's name, you can see a list of every other UK company they are currently involved with or have been in the past. This is vital for spotting "serial entrepreneurs" or identifying potential conflicts of interest. For more on these roles, see our post on the legal duties of a director.
Understanding PSCs
The PSC register was introduced to increase corporate transparency. It identifies individuals who own or control more than 25% of the shares or voting rights. This prevents individuals from hiding behind layers of corporate shells. If a company is owned by another company, the "relevant legal entity" will be listed here.
- Resigned Officers: Check how long past directors stayed with the firm.
- Nationality and Occupation: Provides context on the expertise of the board.
- Nature of Control: Specifies if the control is through shares, voting rights, or the right to appoint/remove directors.
- Service Address: Usually different from the home address to protect the director's privacy.
️ Identifying Red Flags and Risks
Using the search tool for due diligence requires a critical eye. While Companies House does not verify the absolute accuracy of every filed document, the presence (or absence) of certain filings can signal trouble.
Late Filings and Overdue Accounts
If a company’s status shows "Accounts Overdue" or "Confirmation Statement Overdue," it is a major red flag. This often indicates financial distress or administrative chaos. Frequent changes in the registered office address or a high turnover of directors within a short period can also suggest instability.
Disqualified Directors
Companies House maintains a separate register for disqualified directors. If you are entering a major partnership, it is worth checking if any of the company's key influencers are on this list, as it is a criminal offense for a disqualified person to manage a company without court permission.
- Watch for Compulsory Strike-off notices, which are often triggered by failing to file accounts.
- Investigate Cessation of PSCs to see if major investors are pulling out.
- Look at Liquidation filings which indicate the company is being wound up to pay creditors.
- Cross-reference the SIC Code with the company's stated activities to ensure legitimacy.
