How to Register a New Business in the UK
Starting a business is an exciting milestone, and one of the first practical steps is understanding how to register a new business in the UK correctly. The registration process depends on how you choose to operate, as a sole trader, in partnership with others, or through a limited company. Getting the paperwork right from the outset keeps you compliant and provides a solid foundation for growth and long-term stability.
In this guide, we explain what registering a business involves, who you need to notify, and what action is required, alongside clear pointers to official guidance so you can move forward with confidence.
What Does It Mean to Register a New Business?
When you register a new business, you are formally notifying the relevant authorities that you are trading. In the UK, this typically involves registering with:
The exact process will depend on your chosen business structure, so selecting the right structure is your first important decision.
Choose Your Business Structure
Before you register a new business, consider which legal structure is most appropriate. This decision affects how you pay tax, your administrative responsibilities, and the extent to which your personal assets are protected.
The most common structures are:
- Sole Trader: Simple to set up, you run the business as an individual
- Partnership: Two or more people share ownership and responsibility
- Limited Company: A separate legal entity offering personal liability protection
- Limited Liability Partnership (LLP): Like a partnership but with limited liability
If you're unsure which is best for you, it's worth talking to an accountant or adviser. Getting it right from the start makes future compliance much easier.
Registering as a Sole Trader
If you operate as a sole trader, you do not need to register with Companies House. Instead, you must inform HMRC that you are self-employed so you can pay Income Tax and National Insurance through Self Assessment.
Under current HMRC guidance, you must register if your income from self-employment exceeds £1,000 in a tax year. Registration is completed online through your Government Gateway account. Once registered, you will receive a Unique Taxpayer Reference (UTR), which you will use when submitting your annual tax return.
Partnership Registration Requirements
For a standard partnership, one partner must register the partnership with HMRC. Each partner must also register individually for Self Assessment.
The partnership submits an annual partnership tax return, and each partner reports and pays tax on their share of the profits through their own return.
Registering a Limited Company
If you decide to form a limited company, the process begins with incorporation with Companies House.
To register a limited company, you will need:
- A unique company name
- A registered office address in the UK
- At least one director
- Details of shareholders and share structure
- A SIC code describing your business activities
- Standard constitutional documents (Memorandum and Articles of Association)
Online registration currently costs £100 and is usually processed quickly, while postal applications take longer and cost a bit more. Once approved, Companies House issues a Certificate of Incorporation, confirming that the company legally exists.
You must also register the company for Corporation Tax with HMRC, typically within three months of starting to trade. HMRC will then issue a company UTR for tax filings.
Limited Liability Partnership (LLP) Registration
An LLP also requires registration with both Companies House and HMRC. It combines limited personal liability, similar to a limited company, with partnership-style taxation, meaning members are taxed individually on their share of the profits.
Additional Registrations to Consider
Depending on your circumstances, you may also need to register for:
- VAT if your taxable turnover exceeds the registration threshold
- PAYE if you employ staff
- Industry-specific licences, regulatory approvals or insurance
These requirements depend on your business activity and projected turnover.
Getting It Right from Day One
Taking the time to properly register a new business helps ensure compliance, reduce the risk of penalties, and create clarity around your tax obligations from the start. While the process itself is straightforward, choosing the right structure and understanding your responsibilities can be more complex.
