How to register a company in the UK step by step

Who is this for?

This page is for founders who want a UK Ltd and want the process to be predictable - whether you’re UK-based, a first-time director, or an overseas founder who needs a compliant UK registered office and a fully remote setup.

• If you want a simple one‑director / one‑shareholder setup
• If you need a UK registered office address and mail handling
• If you want to incorporate quickly (often 48-72 hours once details/checks are complete)
• If you want us to handle everything for you end-to-end

Real example (typical UK setup)

Scenario: A consultant wants to invoice UK/EU clients and keep admin minimal.

• Company type: Private limited company (Ltd)
• Directors: 1 director
• Ownership: 100 ordinary shares to 1 shareholder (simple ownership record)
• Address: Registered office service (so statutory mail is handled reliably)
• Compliance plan: Confirmation statement + accounts/tax handled on time

The exact details change with your goals (co-founders, investors, overseas ownership), but this is the “clean” baseline we often start from.

Step 1: Choose the right UK company structure

Most founders choosing “UK company registration” are looking for a private limited company (Ltd). It is the standard structure for trading businesses, investment holding companies, and international founders who want a UK presence. It provides limited liability and a recognised framework for ownership (shares).

If you’re unsure, the most important early question is how you want to own and control the business: who will be a director, who will be a shareholder, and who is the PSC. Getting this right up front avoids rework and compliance headaches later.

Step 2: Choose a compliant company name

The UK has rules around names (including “same as” restrictions and sensitive words). If your first choice isn’t available, having a few alternatives helps keep the process fast. If branding matters, we can also help you consider how the name will look on invoices, bank applications, and overseas documentation.

Step 3: Set your registered office address

Every UK limited company must have a registered office address in the UK jurisdiction where it is incorporated. This address appears on the Companies House register and is used for statutory mail. If you don’t have a suitable UK address, you can use a compliant registered office service.

If privacy is a concern, this step is where we usually reduce friction: a professional registered office can help avoid using a home address for the company’s public “official” address. For the full detail, see Do I need a UK registered office address?

Step 4: Appoint directors and confirm the PSC position

A director is responsible for running the company and meeting legal duties. A PSC (Person with Significant Control) is usually someone who ultimately owns or controls the company. In many simple companies, the director and PSC are the same person - but not always.

This is also where identity verification obligations may apply, depending on your role and how filings are made. If you’re planning ahead, read What is Companies House identity verification?

Step 5: Decide the share structure (ownership)

Shares define ownership. For many new companies, the share structure is simple (for example, one shareholder with one class of ordinary shares). But if you expect future investors, different founders, or staged ownership changes, setting up the structure correctly saves time later.

If you want flexibility - like bringing in a co-founder, issuing shares later, or transferring ownership - we can structure this to stay compliant and practical for banks and counterparties.

Step 6: Choose SIC codes and a clear business activity description

SIC codes describe what your company does. They matter for compliance and can affect how banks and providers understand your business. If you have multiple activities, it’s common to choose more than one code.

Step 7: File your incorporation with Companies House

Once details are confirmed, the incorporation application is submitted to Companies House. The core point here is accuracy: incorrect dates, names, or control details can create rejections or future compliance issues.

If speed matters, we keep it simple: we collect the right data once, prepare the filing correctly, and submit promptly. Many clients complete within 48-72 hours, depending on processing and checks.

Step 8: What happens after incorporation?

Incorporation is the start, not the end. Most companies need an organised approach to ongoing compliance: maintaining statutory registers, keeping Companies House details up to date, filing confirmation statements, and handling accounting/tax responsibilities.

If you want a “done-for-you” setup, our services are designed so you can stay focused on the business while we handle the admin. Explore compliance & filings, or if you’re ready, book a consultation.

Common mistakes to avoid (that slow down UK company registration)

• Leaving the registered office decision too late: it’s required to incorporate and delays are common if you don’t have a compliant UK address ready.
• Director/PSC details that don’t match documents: inconsistencies often cause rework and can impact verification steps.
• Overcomplicating shares at day one: if you don’t need multiple classes yet, start clean and add complexity later with the right documents.
• Choosing vague SIC codes: pick codes that reflect what you actually do to reduce friction with banks and compliance checks.
• Ignoring “after incorporation” obligations: missing confirmation statements and accounts deadlines creates avoidable risk.
