What information about my company is public at Companies House?
Considerably more than most people expect, and it is free for anyone to search — competitors, customers, journalists and members of the public included.
What is always public:
Company name, number, registered office address and status.
Directors' names, month and year of birth, nationality, occupation and service address. The full date of birth and residential address are suppressed on the public record, but a director's usual residential address is held by Companies House and disclosed in limited circumstances — and if you use your home as the registered office, that address is public.
Persons with significant control (PSC) — anyone holding more than 25% of shares or voting rights, or otherwise exercising significant influence. This deliberately makes beneficial ownership visible.
Shareholders, via the confirmation statement, including shareholdings and transfers.
Accounts, filed annually. Small companies and micro-entities may file abridged or filleted accounts, omitting the profit and loss account — which is why a small company's turnover and profit are frequently not visible while its balance sheet is.
Confirmation statements, mortgages and charges registered against the company, and filings such as appointments, resignations and changes of address.
The full filing history, including everything filed previously — nothing is removed when it changes. Past addresses, past directors and past accounts remain visible indefinitely.
What this means practically:
Anyone can assess your finances, within the limits of what you file. Customers and suppliers do this routinely for credit decisions, and so do competitors.
Late filing is visible and is a reputational and credit signal, as well as attracting automatic penalties.
A home address used as a registered office is published permanently, which is why a service address is worth paying for. Removing a previously published address is possible in limited circumstances but is not straightforward.
Reforms under the Economic Crime and Corporate Transparency Act have introduced identity verification for directors and PSCs and greater powers to query filings — so the accuracy of the register is being tightened.
What is not public: day-to-day trading, customers, contracts, employee details, and bank information.
