Companies House

Companies House is the official registrar of companies for the United Kingdom. Think of it as the ultimate public library for UK corporate life, run as a government executive agency. Its primary job is to incorporate new limited companies, dissolve those that have run their course, and, most importantly for investors, to keep a detailed, publicly accessible record of every company's information. For decades, this information was cumbersome to access, but today, its digital service provides a free-to-access treasure trove of documents. This transparency makes Companies House an indispensable first stop for anyone conducting due diligence on a UK-based business, whether it's a giant public corporation or a small private firm. For the meticulous value investor, it's a source of raw, unfiltered data straight from the source—a crucial tool for separating investment fact from market fiction.

What Information Can You Find?

The Companies House digital service is a goldmine of primary source documents. When you look up a company, you gain access to its entire filing history, often going back decades. This allows you to build a comprehensive picture of its past and present. Key documents you can typically download for free include:

Why is Companies House a Goldmine for Value Investors?

For followers of Benjamin Graham and Warren Buffett, who preach the gospel of independent research, Companies House is nothing short of a superpower. It allows you to bypass the polished narratives of company press releases and analyst reports and get straight to the facts.

Unfiltered, Primary Source Data

The information on Companies House is the official record. There's no marketing spin. When a company files its accounts, those are the accounts. This direct access to raw data is fundamental to value investing, which relies on objective analysis rather than popular opinion. You get to be the analyst, forming your own conclusions from the evidence.

Performing Deep Due Diligence

Are you thinking of investing in a small-cap UK stock? Or perhaps lending money to a private business? Companies House is where your investigation begins.

Spotting Red Flags

Careful study of a company's filing history can reveal numerous red flags that might warn you of trouble ahead.

Understanding Corporate Structures

Complex companies often operate through a web of related entities. By reviewing filings, you can map out the relationships between a parent company and its subsidiaries, helping you understand where the real value and risks lie within a corporate group.

How Does It Compare to the US System?

American investors will be familiar with the Securities and Exchange Commission (SEC) and its EDGAR database. While both serve a purpose of corporate transparency, there's a crucial difference:

This gives UK-focused investors unparalleled insight into the private sector, which is often opaque in other countries. The ability to scrutinise the financials of a key private supplier or competitor to a public company you own is a unique analytical edge.

A Practical Tip

The best way to understand the power of Companies House is to use it. Go to the website and play detective. Look up a company you admire, a company you're sceptical of, or even a local business you use (if it's a limited company). Download their accounts and their latest confirmation statement. See who the directors are and check their financial pulse. This hands-on experience is the first step in learning to read the story that the numbers and filings tell—a foundational skill for any serious investor.
