What to Include on a UK Invoice: The Complete Checklist

Whether you're a builder, decorator, freelancer, or any other self-employed worker, your invoices need to include certain information to be valid in the UK. Missing details can delay payments or cause problems with HMRC.

Here's a complete checklist of what every UK invoice should include.

Required on Every UK Invoice

These details are required by UK law on all invoices, regardless of whether you're a sole trader or limited company:

  • The word "Invoice" — clearly visible at the top of the document
  • A unique invoice number — sequential and not repeated (e.g. INV-001, INV-002)
  • Your business name and address — your trading name and registered address
  • Your contact details — phone number and/or email address
  • The client's name and address — the person or company you're billing
  • The invoice date — the date you're issuing the invoice
  • The supply date — the date the goods were delivered or services were completed (can be the same as the invoice date)
  • A description of the goods or services — clear enough that the client knows what they're paying for
  • The quantity and unit price — for each line item
  • The total amount due — clearly displayed

Additional Requirements for VAT-Registered Businesses

If your business is registered for VAT, your invoices must also include:

  • Your VAT registration number
  • The VAT rate applied to each item (usually 20%, but some items are 5% or 0%)
  • The VAT amount for each item
  • The total excluding VAT
  • The total VAT charged
  • The total including VAT

For more on VAT, see our guide on whether tradespeople need to charge VAT.

Additional Requirements for Limited Companies

If you operate as a limited company, you must also include:

  • Your full company name — as registered at Companies House
  • Your company registration number
  • Your registered office address — if different from your trading address

Additional Requirements for CIS Invoices

If you're a subcontractor working under the Construction Industry Scheme, you'll also need:

  • Your UTR (Unique Taxpayer Reference) number
  • Labour and materials separated — CIS deductions only apply to labour
  • The CIS deduction rate and amount — shown for information

See our detailed CIS invoice guide for a full walkthrough.

Recommended Extras (Not Legally Required But Helpful)

These aren't legally required, but including them will help you get paid faster and avoid disputes:

  • Payment terms — when payment is due (e.g. "Payment due within 14 days")
  • Bank details — bank name, sort code, account number, and account name
  • Payment reference — what the client should use as a reference when paying (usually the invoice number)
  • Your logo — makes the invoice look more professional
  • A job reference or PO number — especially useful for commercial clients
  • Site address — if you're a tradesperson who worked at a specific location
  • Late payment terms — e.g. "Interest of 8% plus Bank of England base rate will be charged on late payments"
  • A polite closing note — something like "Thank you for your business"
