Can I Invoice Without a Company?

The short answer: yes, absolutely

In the UK, you do not need a limited company — or any registered company — to invoice clients for your work. Millions of freelancers, consultants, tradespeople, and sole traders send invoices every day as individuals, using only their own name.

There is no legal requirement to incorporate before you can charge for your services. The moment you start offering services and receiving payment, you are operating as a sole trader — the simplest and most common business structure in the UK.

What is a sole trader?

A sole trader is a person who runs a business in their own name, without the legal separation of a limited company. You and the business are the same legal entity — your income is your business income, and you report it on your self-assessment tax return each year.

Sole trading is the default structure for freelancers. You do not need to “apply” to become one — you simply start working. The main obligation is to register with HMRC for self-assessment once your income from self-employment exceeds £1,000 in a tax year (the trading allowance threshold).

In the UK, there are estimated to be over 3.1 million sole traders. Freelancers, consultants, designers, developers, writers, photographers, plumbers, electricians — most work as sole traders, not limited companies.

What you need on your invoice

As a sole trader (not VAT-registered), HMRC requires the following on every invoice:

• Your name — or your trading name if you use one (more on this below)
• Your address — this can be your home address or a registered office address
• Client's name and address
• A unique invoice number — sequential numbering (INV-001, INV-002, etc.) keeps things tidy
• Invoice date
• Clear description of the goods or services
• The amount owed
• Payment terms — e.g. “Payment due within 30 days”
• How to pay — your bank account details (sort code and account number) or a payment link

That is it. No company registration number, no Companies House filing, no legal entity required. Many sole traders include an email address and phone number for queries — not a requirement, but good practice.

Do you need to register anything first?

For the purposes of invoicing, no — you can send an invoice on day one without registering anywhere.

However, you do have a tax obligation to register with HMRC for self-assessment if your total self-employment income is more than £1,000 in a tax year (April to April). You should register by 5 October in the second tax year of trading — so if you start freelancing in the 2025/26 tax year, register by 5 October 2026.

Registering is quick. You can do it on GOV.UK in about 15 minutes. You will receive a Unique Taxpayer Reference (UTR) number in the post within 10 days, which is all you need to file a self-assessment return each year.

You do not need a UTR to start invoicing — it is a tax reference, not a trading licence.

Trading name vs your own name

You can invoice using your own name (e.g. “Jane Smith”) or under a trading name— a business name you choose that is separate from your personal name (e.g. “Northfield Studio”).

If you use a trading name:

• You do not need to register it anywhere (unlike a limited company name)
• You can use it on invoices, a website, business cards — anything you like
• Your bank account will still be in your personal name, unless you open a business account under the trading name
• You cannot use the words “Limited”, “Ltd”, or “PLC” — those imply incorporation
• You cannot use a name that's already trademarked or confusingly similar to an existing registered company

Even with a trading name, you are still legally a sole trader operating under your own name. If a client needs to write a cheque (unlikely, but it happens), it should be made out to you personally, not the trading name — unless you have a business account in that name.

VAT and invoicing

If your turnover exceeds £90,000 in any rolling 12-month period, you must register for VAT — but this is about the scale of your business, not its structure. Sole traders absolutely can be VAT-registered.

Once you are VAT-registered, your invoices need additional fields: your VAT registration number, the VAT rate applied, the net amount, the VAT amount, and the gross total. See our VAT for UK Freelancers guide for the full details.

Below £90,000 turnover, VAT is optional — you charge the net amount only, and your invoices do not mention VAT at all.

When to consider a limited company instead

Most freelancers do not need a limited company, especially when starting out. Incorporating makes sense when:

• Your profit is consistently above roughly £50,000–£60,000 per year — at that level, the tax efficiency of paying yourself a salary plus dividends from a company can outweigh the extra admin
• Clients or contracts require you to operate through a company (some large corporates and public sector clients have this requirement)
• You want liability protection — as a sole trader, your personal assets are at risk if a client sues you; a limited company creates a legal separation
• You are taking on employees or significant financial risk

Until those thresholds apply to you, sole trading is simpler, cheaper, and has less administrative overhead. You can always incorporate later — many freelancers trade as sole traders for years before it becomes worth the complexity.
