Searching for a plumber's invoice template usually means one thing: the job's done and you want paying without a fight. Here's what a UK invoice needs to be taken seriously (and paid promptly), plus a way to produce one in the time it takes to walk back to the van.
What a plumber's invoice must include
- The word "Invoice" and a unique number. Sequential numbering keeps your records straight and looks professional.
- Your business details. Trading name, address, contact. Sole traders should invoice under their own name or trading name.
- The customer's name and address.
- Itemised work with prices. "Replace ball valve" and "Clear blocked waste" as separate lines. Lump sums invite queries; itemised lines get paid.
- Date and total. If you're VAT registered, show the VAT breakdown and your VAT number.
- How to pay. Bank details or accepted methods, right on the invoice. Every extra step a customer must take to find out how to pay costs you days.
Why templates slow you down
The template isn't the work: the typing is. Every evening spent copying job details into a spreadsheet is an evening not quoting the next job. And when the invoice finally goes out two days late, it gets paid two weeks late.
Invoice by voice note instead
With NippyAgent you say the job into WhatsApp: "Invoice for Sarah Hughes, replace ball valve, sixty five, clear blocked waste, eighty." A numbered, itemised PDF invoice comes back in under a minute with your details on it. Send it to the customer before you've left the drive. No app, nothing to install.

Frequently asked
Is a WhatsApp invoice legally valid? An invoice is a document, not a delivery method. A PDF invoice with the required details is as valid sent by WhatsApp as by post or email.
What if I'm not VAT registered? Invoice without VAT and don't show a VAT line. Once registered, your invoices must show the VAT number and breakdown.
