Invoice Template for Plumbers (UK)

Payment terms and deposits for plumbers

Typical terms: Domestic: on completion. Commercial and contractor work: 30 days, sometimes with retention.

Deposits: Materials deposit for larger jobs, so you are not funding parts.

Agree your terms in writing before you start. The late payment clause generator writes them for you.

What to include on a plumber's invoice

Specific to your work

• Labour and parts as separate lines.
• Your Gas Safe number where relevant, and warranty details.
• The job address if different from the billing address.

Every UK invoice needs

• Your name or business name, address and contact details — and if you're a limited company, its registered name and number.
• The client's name and address (for a company, its exact registered name — check it here).
• A unique, sequential invoice number, and the invoice date.
• A clear description of the work, the date(s) supplied and the amount for each item.
• The total, the due date and how to pay (bank details or a payment link).
• If you're VAT-registered: your VAT number, the VAT rate and amount — use the VAT calculator.
