VAT Invoice Requirements in the UK
A clear checklist of what a UK VAT invoice must show — and the difference between full and simplified invoices.
If your business is VAT-registered in the UK, your invoices must meet HMRC's requirements. Here's what to include.
What a full VAT invoice must show
- A unique invoice number and the invoice date.
- Your business name, address, and VAT registration number.
- The customer's name and address.
- A description of the goods or services.
- The VAT rate and amount per item, plus the rate applied.
- The total amount excluding VAT, the VAT total, and the total including VAT.
Full vs simplified invoices
A simplified VAT invoice can be used for retail sales under £250 and needs fewer details. A full VAT invoice is required for most B2B sales. When in doubt, issue a full invoice.
Always check the current rules on the HMRC website — this is general guidance, not tax or legal advice.
