How to Register a Company in the United Kingdom: Step-by-Step Guide

A practical walkthrough of UK company registration, from choosing a structure at Companies House to post-registration tax and compliance duties.

Choosing Your Company Structure

The United Kingdom, with its stable economy and efficient Companies House registry, remains one of the fastest places in the world to incorporate. The most common structure is the Private Company Limited by Shares (Ltd), which requires at least one director, one shareholder and a UK registered office address.

Other options include the Limited Liability Partnership (LLP), popular with professional services firms, and the Public Limited Company (PLC) for businesses raising public capital (minimum £50,000 allotted share capital).

The Registration Process

Registration is completed online through Companies House, typically within 24 hours, for a fee of £50. You will need: a unique company name, a registered office address, details of directors and shareholders, a memorandum of association, and a statement of persons with significant control (PSC).

Post-Registration Obligations

After incorporation you must register for Corporation Tax with HMRC within 3 months of starting to trade. The UK corporation tax main rate is 25% (19% small profits rate). Companies must file annual accounts and a confirmation statement with Companies House, and VAT registration becomes mandatory once taxable turnover exceeds £90,000.

Costs and Timeline

A standard online incorporation costs £50 and completes in 1–2 working days. Using a formation agent typically costs £100–£300 including a registered office service. Bank account opening adds 1–3 weeks for non-resident founders.
