Find out how to register a business in the UK, from choosing your structure to filing with HMRC, so you start strong and stay compliant.
Starting a business in the UK involves more than developing a great idea. Choosing the correct business structure and registering with the appropriate authorities are important steps to ensure your business operates legally and efficiently from the beginning.

The way you register your business depends on the legal structure you choose. The most common options in the UK are:
Each structure has different legal, financial and tax responsibilities.
A sole trader is an individual who owns and runs a business independently. This is the simplest business structure and is popular with freelancers, consultants and small business owners.
As a sole trader:
You should usually register as a sole trader if:
To register as a sole trader, you must:
Construction contractors and subcontractors may also need to register under the Construction Industry Scheme (CIS).
A limited company is a separate legal entity from its owners. This means the company itself is responsible for its debts and liabilities rather than the shareholders or directors.
Many businesses choose this structure because it can provide additional legal protection and may offer tax advantages depending on the circumstances.
To set up a limited company, you will need to:
When registering a limited company, you will generally need:

Partners share profits and are jointly responsible for debts and obligations unless the partnership has a different legal structure, such as a Limited Liability Partnership (LLP).

Limited companies have greater flexibility when choosing names but must ensure the name is available and does not infringe on existing trademarks or registered company names.
Availability can be checked through Companies House before registration.
Partnerships can trade under the partners’ names or a separate business name. However, official documents such as invoices and contracts must clearly identify the business and its partners.
Partnership names cannot include restricted company terms unless legally permitted.
There is no fee to register as a sole trader with HMRC. Costs generally relate only to accounting services and tax obligations.
Registering a limited company with Companies House involves a registration fee, which varies depending on the registration method used and may change over time.
There is no registration fee for a standard partnership with HMRC, although professional advice or accountancy services may incur additional costs.
Choosing the right business structure is one of the first and most important decisions for any new business owner in the UK.
Whether you decide to operate as a sole trader, form a partnership or establish a limited company, registering correctly helps ensure your business remains compliant and ready for growth.
