Register a Limited Company in the UK — Step-by-Step Online Guide

Incorporation formalises your business, limits personal liability, and signals credibility to partners and investors. This guide is built for first-time founders, solo entrepreneurs, international owners setting up a UK entity, and advisers who need a reliable, compliant process. Our formation service delivers clarity from pre-filing to post‑incorporation obligations, so you can register a limited company in the UK with confidence and speed.

Company types and eligibility

The most common structure is a private company limited by shares (Ltd) for profit-seeking businesses. A company limited by guarantee suits not‑for‑profit activities. You need at least one director, one shareholder (they can be the same person), a UK registered office address, and a registered email. A statement of lawful purpose is required. Non‑UK residents can own and direct a UK company, subject to identity and address requirements.

Information and documents you will need

• Proposed company name and SIC code (business activity)
• Registered office in the UK and a registered email address
• Director and shareholder details (full name, DOB, service address)
• Persons with Significant Control (PSC) information
• Share capital, ownership, and standard or bespoke Articles of Association
• Proof of identity and address for compliance screening

How to register online — step by step

1. Choose your structure and name. Confirm the name is unique, not sensitive, and includes “Limited” or “Ltd” (unless exempt).
2. Prepare your details. Gather director, shareholder, PSC and share allotment information.
3. Complete the digital IN01. Enter your registered office, lawful purpose statement, SIC code and articles on our platform.
4. Submit and pay. We transmit securely to Companies House and provide real‑time status updates.
5. Receive incorporation documents. Certificate of Incorporation, Memorandum, Articles and company authentication code are issued electronically.

Fees, timelines, and naming rules

Incorporation involves a Companies House filing fee plus our transparent service fee, displayed before payment. Most online filings are approved within one working day, subject to peak volumes and compliance checks. Names must be distinguishable, avoid restricted terms without consent, and comply with style rules.

Post‑incorporation essentials

• Register for Corporation Tax once you start trading
• Set up PAYE if hiring, and register for VAT when required
• Maintain statutory registers and file the annual confirmation statement
• Prepare accounts and file with Companies House and HMRC on time
• Open a business bank account and keep PSC information current

Common mistakes and practical tips

• Names too similar to existing companies — run an availability search first
• Incorrect SIC selection — choose the code that reflects primary activity
• Using an ineligible address — your registered office must be in the UK
• Omitting PSC details — ensure control thresholds and statements are correct
• Over‑customising articles without legal need — standard model articles suit most startups
