Free invoice template PDF (UK)
A PDF is the safest format to send a client: the layout stays fixed and the invoice cannot be edited by accident. This free UK invoice template PDF covers the fields HMRC expects on a full VAT invoice. You can print it, fill it in a PDF editor, or use the browser generator when you want the totals calculated.
What's included
- A clean A4 invoice layout with UK VAT fields
- Business name, address and optional VAT number
- Customer name and billing address
- Invoice number, invoice date and time of supply
- Line items with description, quantity, unit price and VAT
- Subtotal, VAT breakdown and total including VAT
- Payment terms and a due date
How to use the PDF invoice template
- Download the PDF and open it in your PDF viewer or editor.
- Print it and fill it in by hand if you only need a one-off invoice.
- For a digital version, use a PDF editor to add your business, customer and line-item details.
- Check the VAT rate and totals carefully; a static PDF will not calculate them for you.
- Save a copy as a new PDF and keep the original blank template for next time.
- For repeat invoices, use the online generator so totals and VAT are calculated automatically.
PDF vs Word vs online generator
A PDF is best for the final invoice you send: it preserves the layout across devices and prevents accidental edits. Word is better when you need to change the layout or branding. An online generator is fastest when you want correct totals without manual maths.
A practical workflow is to keep a blank PDF or Word template for reference, but create the actual invoice in the browser generator and save it as a PDF. That gives you a consistent layout and calculated VAT.
UK invoice fields to keep
- A unique, sequential invoice number
- The invoice date and the time of supply
- Your business name, address and VAT number (if registered)
- The customer's name and address
- A clear description of the goods or services
- Quantity, unit price and amount before VAT
- VAT rate and VAT amount for each line
- Total before VAT, total VAT and total including VAT
If you are not VAT registered, do not charge VAT or show a VAT number. Keep a copy of every invoice for your records.
Common PDF invoice mistakes
- Typing totals by hand and making a rounding error
- Sending a PDF that still contains another client's details
- Forgetting to include the invoice date or time of supply
- Using a scanned image that is hard to read or search
- Losing the original file and having no record of what was sent

Frequently asked questions
Is the PDF invoice template free?
Yes. The PDF and the editable Word version are free to download and use for your business.
Can I fill in the PDF digitally?
You can use a PDF editor to add text and save a copy. The template is not a calculated form, so check the totals manually or use the browser generator.
Is PDF better than Word for invoices?
For the final invoice, yes: PDF keeps the layout fixed. Use Word if you need to change the design or branding.
Do I need a VAT number to use the PDF?
No. If you are not VAT registered, remove the VAT number and VAT lines. Only charge VAT if you are registered.
