Freelance invoice template (UK, 2026)

Most UK freelancers lose money by invoicing inconsistently: missing PO numbers, unclear payment terms, and no late-fee language. This template is simple, compliant and designed to get paid faster.

Editorial template · Hustle Report · authority: HMRC (VAT + invoicing guidance)

What to include on a UK freelance invoice

  • Your name / business name + address
  • Client name + address
  • Unique invoice number
  • Invoice date + due date (or payment terms)
  • Clear line items (what was delivered) + totals
  • Bank details / payment method
  • If VAT-registered: VAT number + VAT breakdown

When to send the invoice

  • Fixed-scope project: send immediately on delivery + acceptance
  • Retainer: send on day 1 of the billing month (not the last day)
  • Day-rate contract: weekly or fortnightly invoicing reduces risk

Invoice numbering

Use sequential numbering (e.g. 2026-001, 2026-002). Never reuse a number. If you void an invoice, mark it VOID and keep it in your records.

UK tax notes (quick)

  • If your side income exceeds £1,000/year, Self Assessment registration is required.
  • VAT registration is separate; only required above the VAT threshold (check current HMRC threshold).
  • Keep invoice records for at least 6 years (typical UK record-keeping expectation).

Common questions

Invoice template · United Kingdom · FAQ

  • Do I need to add VAT to my UK freelance invoice?

    Only if you are VAT-registered. If you are not registered, you should not charge VAT and you should not include a VAT number.

  • What payment terms should UK freelancers use?

    Net 7 to Net 14 for small clients is common; Net 30 is common for larger companies. If you can, negotiate Net 14 and invoice at project start for retainers.

  • Do I need a company number to invoice in the UK?

    No. Sole traders can invoice using their name. A company number is only relevant if you are incorporated (Ltd).

  • Where do I read the UK side hustle tax thresholds?

    Use our UK guide here: /freelance-tax/uk

  • Should I invoice weekly or monthly on a day-rate contract?

    Weekly reduces risk and improves cashflow. Monthly is acceptable for trusted clients, but new clients should start weekly or fortnightly until a pattern is established.

  • What is the most common invoice mistake?

    Missing due date and unclear scope. Always include a due date and a one-line description of what was delivered.
