What a UK invoice must include
A basic invoice needs a unique invoice number, your business name, address and contact details, your customer's name and address, the date, a description of what you sold, the amount charged, and the total due.
If you are VAT registered, a VAT invoice also needs your VAT registration number, the time of supply if it differs from the invoice date, the rate of VAT on each item, and the total VAT. GOV.UK lists the full requirements.
