How to start a small business in the UK: Is it the right step for me?

11th August 2026

If you’ve been dreaming of starting your own business, because you’ve had a unique product idea or have decided it is time to work for yourself, you might have stumbled on one of the most rewarding paths you can take in your lifetime. However, running your own business, whether you are operating as a freelancer or planning to incorporate a limited company, is a decision that should always be made with the right information in your hands.

Running a business involves additional work that an employer would have done for you. It likewise comes with its own benefits, as well as the relinquishing of benefits that a stable, salaried position provides. So, is starting a small business the right step for you? 99p Company Formations discuss below.

Is starting a small business right for you?

Before worrying about business names, websites or Companies House, you need to consider whether starting your own business is truly the right step forward for your life and career.

Being your own boss can provide greater flexibility and control over how you work. You’ll be able to choose your working hours and concentrate on work that genuinely interests you and works to your skills. Self employment can offer greater control over your income and working arrangements, but you will be subject to long hours, irregular income, disruption to your routine, and a loss in employment benefits such as paid leave and pension schemes.

The reality of running a small business will likely be completely different to your expectations.

A talented photographer, for example, may start a photography business because they love taking photographs. Once the business is established, however, they will find themselves spending a significant amount of time responding to enquiries, sending invoices, managing expenses, promoting their services, dealing with suppliers and completing tax and administrative work.

The same applies to almost every type of small business.

If you are considering becoming self employed, ask yourself whether you are comfortable with:

• Taking responsibility for your own income

• Making decisions without an employer providing direction

• Managing periods where sales are unpredictable

• Learning about tax, bookkeeping and business administration

• Finding customers rather than simply completing work

• Working outside conventional hours when necessary

• Investing time and money before the business becomes profitable

• Pushing on when growth is slower than expected

None of these should put you off but sitting with them will give you a more realistic picture of whether you are ready to take this step.

Who can benefit from starting a small business?

There is no single type of person who makes a successful business owner.

Small businesses can suit people who want to turn a professional skill into a business, freelancers who want to formalise their work, people with a product idea, tradespeople, consultants, online sellers and individuals who have identified a problem that customers are willing to pay them to solve.

It can also be a practical way to build an income alongside other commitments. Some people begin with a side business and gradually increase the amount of time they dedicate to it once they have established demand.

The important distinction is between wanting to own a business and having a viable business idea. Ideally, you need both.

How long does it take to start a small business?

Starting a business and building a successful business are two very different things.

The administrative process can be completed relatively quickly with the right resources and support. For example, registering a limited company is a straightforward process, particularly when you already know your company name, registered office address, directors and shareholders.

However, finding customers, developing your reputation and reaching consistent profit margins can take months or even years.

How much money do you need to start a small business?

The answer can range from almost nothing to hundreds of thousands of pounds. Your startup budget should distinguish between one off costs and ongoing costs.

One off costs might include:

• Company formation

• Equipment

• Initial stock

• Branding

• Website development

• Professional advice

Ongoing costs could include:

• Rent

• Utilities

• Software subscriptions

• Insurance

• Marketing

• Accounting

• Stock replenishment

• Transport

• Staff

• Loan repayments

You should also budget for your own personal expenses. If you are leaving employment to start your business, your mortgage or rent, household bills, food, transport and other commitments do not disappear simply because your business is new.

How to get funds to start a small business

Not every small business needs external funding. If you can start the business using your own savings and keep the initial costs low, you may prefer to avoid borrowing altogether.

Otherwise, you may need more substantial funding from the beginning.

Possible sources include:

Personal savings

Using your own money gives you control and means you do not have to make loan repayments or give away part of the business. However, you should be careful about putting all your personal savings into a business that has not yet proven itself.

Business loans

A business loan can provide the capital required to purchase equipment, stock, vehicles or other assets.

The downside is that repayments still need to be made even if sales are lower than expected.

Start up loans

Government backed start up lands may be available to eligible new businesses and can provide both finance and support. Before borrowing, make sure you understand the repayment terms and whether the business can realistically afford the repayments.

Grants

Some businesses may qualify for grants or other forms of local or sector specific support.

Eligibility varies considerably, so don't build your entire financial plan around a grant until you know you qualify.

Investment

If your business has strong growth potential, you may consider external investment. This can provide substantial funding, but investors generally expect something in return, often in the form of shares and a degree of influence over the business.

The best source of funding depends on what you are building. 

Separate your business and personal finances

Keeping business money separate from personal money is one of the simplest habits you can establish. For a limited company, the distinction is particularly important because the company is legally separate from you.

Sole traders are not generally required to have a separate business bank account, although maintaining separate finances can make bookkeeping much easier.

A dedicated business bank account can make it much easier to:

• Track sales.

• Record expenses.

• Reconcile transactions.

• Prepare accounts.

• Understand whether the business is actually profitable.

Check whether your business needs a licence

Some business activities require specific licences, permissions or registrations. The requirements depend on what you do and where you operate.

This can apply to areas including:

• Food businesses

• Alcohol sales

• Childcare

• Transport

• Financial services

• Street trading

Do you need business insurance? 

Insurance isn't automatically required simply because you have started a small business.

However, the appropriate cover can protect you against risks that could otherwise have a serious financial impact.

The type of insurance you need depends on what your business does.

For example, professional indemnity insurance may be relevant to a consultant, while public liability insurance may be important for a tradesperson working on customers' property.

If you employ people, Employers' Liability insurance is generally a legal requirement, subject to limited exceptions.

Insurance should therefore be considered as part of your risk assessment rather than simply another box to tick during setup.

Decide how you will structure your business

One of the most important decisions you will make is deciding how your business will legally operate. If you are starting a small business, this decision will likely come down to becoming a sole trader or forming a limited company.

The structure you choose affects your responsibilities, taxation, administration and the relationship between you and the business.

Setting up as a sole trader

A sole trader is an individual running a business personally.

It is generally the simplest structure to establish. You don't need to incorporate a company with Companies House; instead, you register for Self Assessment with HMRC when required.

You must register as a sole trader if, broadly, your self employed trading income exceeds £1,000 in a tax year, although there are circumstances where you may need or choose to register for other reasons.

The simplicity can make being a sole trader attractive for anyone testing a small business idea. However, there is an important downside: the business and the individual are not legally separate. This means you are personally responsible for business debts and liabilities.

Setting up a limited company

A private limited company is a separate legal entity from its owners.

You register it with Companies House and appoint at least one director. A company limited by shares must also have at least one shareholder. The company is responsible for its own debts and obligations, subject to the usual rules surrounding limited liability.

A limited company can therefore provide a different legal and financial structure from operating as a sole trader, but it also brings additional administration.

Companies have to keep appropriate records and file documents such as annual accounts and confirmation statements, while the company itself may be liable for Corporation Tax.

Which structure is right for you?

A sole trader structure may be attractive if you want to keep administration simple and your business is relatively straightforward. A limited company may be more appropriate if you want the business to operate as a separate legal entity, plan to take on shareholders or investment, or expect the business to grow into a larger operation.

Your decision should take account of your expected income, liability, tax position, future plans and the level of administration you are prepared to manage.

How to register as self employed

If you decide to set up as a sole trader, you'll generally need to register for self assessment with HMRC when you meet the relevant conditions. Registration gives HMRC the information it needs to know that you are operating as a self employed individual and may need to submit a tax return.

You will also need to keep records of your income and allowable business expenses so you can calculate your taxable profit.

Don't leave this until the last minute. HMRC has registration and tax return deadlines, and failing to register when required can result in penalties.

Being self employed also means planning for your tax bill. Unlike an employee, you won't necessarily have Income Tax deducted automatically from every payment you receive.

Setting money aside throughout the year can make a significant difference when your tax bill becomes due.

How to set up a limited company

If you decide that a limited company is the right structure for your small business, the process starts with choosing how you want the company to operate.

You will need to decide on:

• A company name

• A registered office address

• At least one director

• At least one shareholder for a company limited by shares

• The company's share structure

• People with Significant Control

You will also need to file incorporation documents that will establish the company's legal structure. These include the memorandum of association and Articles of Association. Once Companies House accepts the application, your company is incorporated and receives its company registration number and certificate of incorporation.

Plan for the business you want to become

Your first version of the business does not need to look like your final version.

You might start as a sole trader and later incorporate a limited company. You might start working from home and eventually move into premises. You might begin alone and eventually employ staff. You might sell one service and later introduce several. There is nothing wrong with starting small.

In fact, keeping your initial costs low can give you more time to test your idea before committing significant amounts of money. The important thing is to review your business regularly and ask whether the structure, pricing, marketing and finances still make sense.

You might benefit from seeking business advice, even in the early stages, to protect your investment.
