Learn the legal requirements to form a private limited company in England and Wales, including director duties, registered office rules, identity verification, required documents, PSC obligations and post‑incorporation compliance under Companies House and company law.
Forming a private limited company is a common way to structure a business in England and Wales. A private limited company is a legal entity separate from its owners, giving them limited liability for business debts. The law sets out specific requirements to ensure transparency, accountability and compliance with corporate regulation. This article explains all legal requirements in clear, accessible language, with practical context for students, solicitors, and members of the public without prior legal knowledge.
What Is a Private Limited Company?
A private limited company (often abbreviated “Ltd”) is a business structure under the Companies Act 2006. It is incorporated when registered with Companies House, the UK registrar of companies. Once incorporated, the company becomes a legal person capable of entering contracts, owning assets, paying tax, and being subject to legal claims. A private limited company cannot offer its shares to the general public.
Forming a company involves meeting legal criteria from the outset and maintaining statutory compliance afterwards. Understanding these requirements avoids delays, errors or possible enforcement actions by Companies House or other authorities.
Minimum Legal Requirements
1. At Least One Director
Every private limited company must have at least one director who is a natural person aged 16 or over. Directors are legally responsible for running the company, ensuring compliance with company law, filing annual accounts, and keeping accurate records. There is no longer a legal requirement for a company secretary for most private limited companies, although one may be appointed if desired.
Directors must act within the law; breaches can lead to fines, disqualification from being a director, or personal liability for certain debts.
2. Registered Office Address
A company must have a registered office address in England and Wales. This is the official address where Companies House and HM Revenue & Customs (HMRC) send legal notices and statutory correspondence. The registered office address is publicly available on the Companies House register.
You should ensure that the address is monitored regularly, as legal documents and formal notices will be sent here.
3. Company Name Rules
The company name must comply with statutory naming rules:
- It must be unique and not too similar to an existing name on the Companies House register.
- It must avoid sensitive or restricted words unless you have special approval (for example terms like “bank”, “trust”, or “charity”).
- It must include “Limited” or “Ltd” at the end, indicating limited liability, unless you obtain a specific exemption.
Choosing an appropriate SIC (Standard Industrial Classification) code that reflects your primary business activity is also required during registration.
4. Identity Verification (New Mandatory Requirement)
Under recent reforms introduced by the Economic Crime and Corporate Transparency Act 2023, identity verification is now a legal requirement for individuals involved in forming and running companies. From 18 November 2025, new directors and persons with significant control (PSCs) must verify their identity before they can be registered with Companies House. Existing directors and PSCs will also have deadlines during a transition period to complete verification.
The verification process involves registering with GOV.UK One Login or through an Authorised Corporate Service Provider (ACSP), after which individuals receive a unique personal code used in incorporation filings.
Failure to verify identity can result in legal penalties for directors and may lead to the rejection of filings or company documents.
Required Documents at Incorporation
When you apply to form a company, you must submit specific documents to Companies House:
Memorandum of Association
A legal statement signed by all subscribers (initial members/shareholders) confirming they wish to form the company. It may be automatically generated in online applications.
Articles of Association
These are the rules governing how the company operates. You can use model articles provided by Companies House or prepare bespoke articles. Articles govern directors' powers, decision‑making, and shareholder rights.
Statement of Capital or Guarantee
- For a company limited by shares: a statement of capital outlining share classes, rights, and the total number of shares.
- For a company limited by guarantee: a statement of guarantee specifying the amount each member agrees to contribute to liabilities if the company is wound up.
People With Significant Control (PSCs)
Companies must identify and record persons with significant control - individuals who hold more than 25% of shares or voting rights, or who can otherwise exert significant influence over the company. PSC information is submitted to Companies House and appears on the public register.
PSCs also must verify their identity under the new legal framework.
Filing and Fees
To incorporate, you must submit your application online through the Companies House Web Incorporation Service or by post using Form IN01 with the supporting documents listed above. The standard online fee is £100. Postal filings cost more and take longer to process.
Companies House reviews the documents for compliance with legal requirements and, if accepted, issues a certificate of incorporation confirming legal existence.
Post‑Incorporation Legal Obligations
Forming the company is only the start of statutory duties. Once incorporated, directors must ensure ongoing compliance, including:
- Filing annual accounts with Companies House.
- Submitting a confirmation statement at least once every 12 months confirming register accuracy.
- Maintaining statutory registers of directors, members, and PSCs.
- Notifying Companies House of changes, including changes in directors, registered office address or shareholdings.
- Registering for Corporation Tax with HMRC within three months of starting to trade.
Failure to file required documents on time can lead to financial penalties, director disqualification proceedings, or even company strike‑off in serious cases.
Risks and Common Compliance Issues
Inaccurate or incomplete filings: Omissions or errors in the incorporation documents can lead to rejection or delays. Confirming correct particulars before submission is essential.
Name disputes and sensitive words: Choosing a company name that conflicts with existing names or includes restricted terms without approval can result in refusal.
Identity verification failure: Errors in ID verification or delays in compliance with the post‑November 2025 regime could prevent successful incorporation or future filings.
Public register visibility: Registered office addresses and certain company details are publicly accessible. Companies should plan how sensitive business information is managed.

Do directors have to be UK residents?
No. Non‑UK residents can be directors of a private limited company, but they must still complete identity verification and meet all statutory requirements, including having a UK registered office address.
Can one person be both director and shareholder?
Yes. A single person can simultaneously be the director and sole shareholder of a private limited company.
Is a company secretary required?
Not for most private limited companies. The role remains optional unless specified in the articles of association.
