Set up a UK limited company and two requirements appear almost immediately: you need at least one director, and you need a registered office. They sound like dull admin, but they sit at the heart of how companies are run and held accountable. Here is what each means in plain terms.
The two essentials
Every UK limited company must have at least one director and a registered office address. The director is the person legally responsible for running the company. The registered office is the company's official address for legal and government correspondence. Neither is optional, and both are recorded on the public register held by Companies House.
That public element matters. UK company law is built on transparency: in exchange for the protection of limited liability, companies must disclose certain information about who runs them and where they can be reached. Directors and the registered office are the foundations of that disclosure.
What a director is responsible for
A director is not just a job title — it carries genuine legal duties. A director must act in the company's best interests and within the law. In broad terms, UK directors are expected to:
- Act within their powers and follow the company's constitution.
- Promote the success of the company for the benefit of its members as a whole.
- Exercise independent judgement and reasonable care, skill and diligence.
- Avoid conflicts of interest and not misuse their position for personal gain.
- Keep proper records and ensure the company files what it must, on time.
Those filing duties are concrete. Directors are responsible for keeping adequate accounting records, preparing and filing annual accounts, and submitting the confirmation statement that keeps the company's public details current. Missing these has real consequences, from penalties to, in serious cases, disqualification.
Being a director is a position of trust and legal responsibility, not merely a label on a business card. The duties apply whether the company is large or a one-person venture.
Our broader explainers on corporate governance and how to register a UK company put these duties in context.
What the registered office is for
The registered office is the company's official address. It is where Companies House, HMRC and the courts send formal correspondence, and it appears on the public register for anyone to see. A few key points:
- It must be a real address in the UK (in the relevant jurisdiction — England and Wales, Scotland, or Northern Ireland) where post can actually be received and dealt with.
- It does not have to be where the company trades. A business can operate from one place and use a different registered office.
- It is public, which is why many directors of small companies use an accountant's or formation agent's address rather than their home, for privacy.
The registered office also has a practical legal function: documents formally delivered there are treated as properly served on the company. That is why it must be a genuine, monitored address — ignoring official post sent to it is not a defence.
How appointments work at Companies House
Companies House is the UK's registrar of companies, and it is the body that must be kept informed of who the directors are and where the registered office sits. The principle is simple: the public register must reflect reality, so changes have to be reported.
In practice that means:
- Appointing a director. When someone becomes a director — at formation or later — their appointment and required details are filed with Companies House.
- Changes and resignations. If a director resigns, is removed, or their details change, that too must be reported, usually promptly.
- Changing the registered office. A company can move its registered office, but the change only takes effect once it is filed and recorded.
Most of this is done through Companies House's online filing service. Companies sometimes note these foundational steps publicly as they get established; London consultancy CM Beyer, for instance, confirmed its registered office and initial board appointments as part of formally setting itself up — a routine but necessary milestone for any new company.
A quick reference
| Element | What it is | Reported to |
|---|---|---|
| Director | Person legally responsible for running the company | Companies House |
| Registered office | Official UK address for legal correspondence | Companies House |
| Confirmation statement | Annual filing keeping details current | Companies House |
A note on advice
This article explains UK company directors and registered offices at a general, informational level. It is not legal advice. Directors' duties and filing obligations carry legal consequences, and the right steps depend on your company's circumstances. For authoritative detail, see the official guidance at GOV.UK and Companies House, or speak to a qualified professional such as an accountant or solicitor.
The bottom line
A UK limited company needs at least one director and a registered office, and both are matters of public record. The director carries real legal duties — acting in the company's interests, keeping proper records and filing on time. The registered office is the company's official address for legal and government post, which must be a genuine UK address even if the business trades elsewhere. And because the system runs on transparency, appointments, resignations and address changes all have to be reported to Companies House. Understand these basics and the rest of running a compliant company becomes far less daunting.
