How to Research a UK Company: A Step-by-Step Guide

To research a UK company, start with the public Companies House record and work outward: confirm it exists and is active, check who runs and owns it, read its accounts and filing history, and look for signals — charges, address changes, resignations — that add context. Almost everything you need is public and free. This guide walks through each step and what it actually tells you.

Step 1 — Confirm the company and its status

Search the company by name or number and confirm the basics: it is a real, registered company, its status is active (not dissolved or in liquidation), and its incorporation date. A company that formed last week is a very different prospect — or risk — from one trading for twenty years. You can browse companies by industry, region or city to put one in context.

Step 2 — Check the people

Look at the directors and secretaries: who they are, when they were appointed, and what other companies they run. A director with a long trail of dissolved companies is worth noting. See company director search for how to follow a person across companies.

Step 3 — Check ownership and control

Directors run a company day to day, but the persons with significant control (PSCs) ultimately own or control it — typically anyone holding more than 25% of shares or voting rights. The PSC record tells you who is really behind the business, and a recent PSC change often marks a sale or investment.

Step 4 — Read the accounts

A company's annual accounts show its financial position — though how much detail you get depends on its size, as small and micro companies file less. Look at net worth, whether accounts are filed on time, and the trend across years. Late or overdue accounts are a genuine red flag.

Step 5 — Read the filing history

The filing history is a dated timeline of everything the company has told Companies House. Scan it for pattern and pace: frequent officer changes, a new charge (secured borrowing), or a registered-office move can all be meaningful in context.

Step 6 — Watch for change

Research is a snapshot; companies change. If the company matters to you — a prospect, a supplier, a competitor — track it and get alerted when it files, changes directors or moves. That's what company monitoring is for.

Doing this at scale

Researching one company is a manual job. Researching many — every new company in your market, say — needs a tool that searches the live register in bulk and assembles each company's people, ownership and filings into one report. That's the difference between the free register and a company database built for research and prospecting. Different jobs use it differently — see the use-case guides for accountants, recruiters, agencies and sales teams.
