How to Start a Business in the UK: A Practical Step-by-Step Guide

Thinking of starting a business in the UK but unsure where to begin?

Whether you're starting a small business, launching a side hustle or expanding an existing company, understanding the process can help you avoid costly mistakes.

Starting a business in the UK involves more than registering with Companies House. You need the right business structure, a financial plan and an understanding of your legal responsibilities.

This guide explains how to start a business in the UK in eight practical steps, including registration, taxes, funding and compliance.

Starting a Business in the UK: What You Need to Know

Before you begin, here are a few important things:

1. You can start as a sole trader, partnership or limited company.
2. Registering a limited company online costs £100 as of November 2026.
3. Your business structure determines your tax and reporting responsibilities.
4. Some industries require licences or regulatory approval before trading.
5. Funding may be available, depending on your circumstances and eligibility.
6. Non-UK residents can generally own a UK company, but company ownership does not automatically grant permission to work in the UK.

Here is how to get started.

Step 1: Research Your Business Idea and Create a Business Plan

Before spending money, find out whether people actually need your product or service.

For example, if you want to start a cleaning business, research the demand in your preferred location, your competitors and what customers are willing to pay.

Ask yourself:

• Who are my potential customers?
• What problem am I solving?
• How will the business make money?
• What will make my business different?

Once you've researched your idea, prepare a simple business plan covering your services, customers, pricing, startup costs, marketing and financial projections.

Why is this important? A business plan helps you understand whether your idea is viable and can support funding applications.

Step 2: Choose the Right Business Structure

One of the most important decisions is choosing how your business will operate legally.

Here are three common structures:

Sole Trader

You run the business personally and are generally responsible for its debts. Simple to establish.

Limited Company

A separate legal entity. Shareholders generally have limited liability, but the company has additional filing obligations.

Partnership

Two or more people run a business together. Liability depends on the partnership structure.

WHICH SHOULD YOU CHOOSE?

A freelancer may prefer operating as a sole trader, while someone planning to bring in shareholders or build a larger organisation may consider a limited company.

Your choice should depend on your business activities, risks, financial position and long-term plans.

At Horeb Limited, we help entrepreneurs assess their business ideas and identify appropriate structures before registration.

Step 3: Choose a Business Name and Register Your Business

Before registration, check whether your business name is available and whether it conflicts with an existing trade mark.

Use the Companies House register and UK trade mark search.

How to Register as a Sole Trader

You generally need to register for Self Assessment with HMRC if your gross trading income exceeds £1,000 in a tax year, or if other registration conditions apply.

Register as a Sole Trader — GOV.UK

How to Register a Limited Company

You'll generally need:

1. Your company name and UK registered office address.
2. Director and shareholder information.
3. Details of people with significant control (PSCs).
4. A SIC code describing your business activities.
5. Company formation documents and required identity verification details.

How much does it cost?

As of November 2026:

Online incorporation

£100

Paper incorporation

£124

Online confirmation statement

£50 per 12-month payment period

The confirmation statement is an ongoing requirement, separate from incorporation.

Important update: Companies House identity verification is now a legal requirement for directors and PSCs, subject to applicable deadlines. Check the process before registering.

Step 4: Understand Your Tax Responsibilities

The taxes you pay depend on your business structure, profits and activities.

Here are the main ones to know:

Corporation Tax

Qualifying companies pay 19% on profits up to £50,000 and 25% above £250,000. Marginal Relief may apply between these thresholds.

Income Tax

Sole traders generally pay Income Tax on taxable profits, with National Insurance potentially applicable.

VAT

Most UK-established businesses must register if taxable turnover exceeds £90,000 over a rolling 12-month period, or is expected to exceed it in the next 30 days.

PAYE

Employers may need to register with HMRC and operate payroll deductions.

Corporation Tax thresholds can be adjusted for associated companies or short accounting periods. VAT rules differ in some circumstances for businesses established outside the UK.

Important: Making Tax Digital

Making Tax Digital for Income Tax is being introduced in stages for qualifying sole traders and landlords.

The applicable qualifying income thresholds are:

Over £50,000 — from 6 April 2026.

Over £30,000 — from 6 April 2027.

Over £20,000 — from 6 April 2028.

Those affected must use compatible software to keep digital records and submit required updates.

Check Making Tax Digital requirements — GOV.UK

Practical advice: Set up proper bookkeeping from the beginning and consult a qualified accountant where needed.

Step 5: Open a Business Bank Account

Keeping your personal and business finances separate helps you monitor expenses, prepare accounts and manage cash flow.

Banks may request:

• Proof of identity and address.
• Business registration details.
• Director or ownership information.
• Details of your business activities and expected transactions.

Limited companies should keep their finances separate from their owners' personal finances. A separate business account is also advisable for sole traders.

Note: Registering a UK company does not automatically guarantee access to a UK business bank account, particularly for overseas founders.

Step 6: Check Licences, Insurance and Business Compliance

Not every registered business can start operating immediately.

Some industries need additional approvals.

For example:

Food businesses: Local authority registration and food safety compliance.

Childcare businesses: Registration with the relevant childcare regulator where required.

Care businesses: Approval from the appropriate care regulator for regulated activities.

Transport and construction: Relevant licences, qualifications and safety requirements.

You may also need public liability, professional indemnity or employers' liability insurance. Employers' liability insurance is generally compulsory for employers, subject to exemptions.

Businesses handling personal data must meet relevant data protection requirements and may need to pay an ICO data protection fee.

Check the licences your business needs — GOV.UK

Remember: Company registration alone does not give you permission to undertake every regulated business activity.

Step 7: Calculate Your Startup Costs and Explore Funding

How much money do you need to start a business in the UK?

There is no fixed amount. It depends on the type of business.

An online consultancy may cost considerably less to establish than a restaurant, nursery or retail shop.

Your startup budget should cover expenses such as:

Setup

Registration, professional support and licences

Operations

Rent, utilities, stock and equipment

Protection

Insurance and relevant compliance costs

Marketing

Website, branding and advertising

Working capital

Money to cover expenses before revenue becomes consistent

Can You Get Funding to Start a Business?

Depending on eligibility, options include business loans, grants, asset finance, private investors and government-backed Start Up Loans.

The UK Start Up Loans scheme offers £500 to £25,000 to eligible applicants. These are personal loans for business purposes, subject to credit checks and other requirements, including UK residency.

Step 8: Start Trading, Market Your Business and Stay Compliant

Once you're ready to operate, you need a clear plan for attracting customers.

Start with a professional website, relevant social media platforms, local marketing and search engine optimisation (SEO).

As you grow, remember to:

• Maintain accurate financial records.
• File required accounts, confirmation statements and tax returns.
• Pay applicable taxes and keep registrations up to date.
• Renew relevant licences and insurance.
• Monitor your business performance and cash flow.

A successful business needs more than registration. It needs customers, proper management and ongoing compliance.

Can You Start a UK Business While Living Abroad?

Yes. Non-UK residents can generally establish or own a UK limited company, subject to the relevant requirements.

However, you must consider registered office requirements, identity verification, banking, taxes and business regulations.

Does owning a UK company give you a visa?

No. Registering a company does not automatically grant permission to live or work in the UK.

It also does not automatically qualify your business for a sponsor licence.

International founders should obtain appropriate professional guidance before making cross-border business decisions.
