How to register a business in the UK

Starting a business in the UK requires a formal notification to the government. While the process is straightforward, the decision to register a sole trader or limited company impacts liability, taxes, and public visibility. Officials advise establishing your business structure before filing with Companies House to ensure the chosen model aligns with your operational goals. The UK government provides resources to help handle these initial steps, though specific rules vary by structure.
Understanding Business Structures
Choosing the right structure is the first practical step. A sole trader means the business is you. You keep the profits, but you also carry all the risk, including debts and legal issues, which can put personal assets on the line. Sole traders must register for Self Assessment if they earn more than £1,000. Partnerships require at least two owners sharing responsibility. Each partner has unlimited liability for debts, though they can split profits based on agreed percentages, allowing partners to focus on their specific strengths, like one partner handling finances while the other manages operations.

Limited companies act as separate legal entities. Directors run the company, while shareholders own it. The business itself is responsible for contract or law breaches, protecting personal assets. However, this structure requires reporting accounts to Companies House, which makes financial details public. Limited liability partnerships (LLPs) blend the two models. Members must register with HMRC separately and file individual tax returns, and profits cannot be retained untaxed. Each structure has specific rules regarding VAT and turnover thresholds, typically set at £90,000 for Self Assessment registration.
While the UK government website outlines the standard procedures, business owners often find that the real-world application of these rules requires more than just following a checklist. In many cases, the paperwork creates a bottleneck just when entrepreneurs want to start selling. This delay can be frustrating when cash flow is dependent on immediate market entry, forcing many to balance the perfect legal setup against the need to generate revenue quickly.

Picking a Company Name
Registering a name is not required for sole traders, but it is mandatory for limited companies and LLPs. A name must be available on the Companies House register and not infringe on Intellectual Property rights. The name cannot be offensive, use sensitive wording, or suggest a connection to the government or the Royal Family. Terms like “royal,” “Windsor,” or “British” are restricted. Punctuation marks can limit availability, so it is often better to stick to letters and numbers, provided the name stays under 160 characters.
Registration Steps and Costs
For a limited company, you must appoint directors, select a Standard Industrial Classification (SIC) code, and create memorandum and articles of association. Partnerships need at least one nominated partner to manage tax returns and records, while LLPs require at least two designated members who must register for Self Assessment individually. All business types must file accounts or tax returns by specific deadlines, such as the October 5 deadline for the second tax year.
