Plumbers · Invoice template

The UK plumber invoice template, and what to put on it.

A plumber's invoice has its own quirks — the callout charge, parts versus labour, and emergency or out-of-hours rates. Here is what to include, a free template, and a faster way to send them.

The checklist

What a plumber's invoice should include.

FieldNotes for plumbers
Your business name and addressPlus contact details and, if registered, your VAT number.
Invoice number and dateUnique and sequential.
Customer detailsName and address of who you billed.
Callout chargeList it separately from labour so it is clear.
Labour and partsSplit them out — customers query a single lump sum more often.
Emergency / out-of-hours rateIf it applies, show the rate so there are no surprises.
VATShow rate and amount if you are VAT-registered.
How to payBank details or a payment link.
This is general information, not tax advice. If you are near the VAT threshold, see the threshold guide below.
The faster way

Skip the template — invoice from WhatsApp.

A template works, but after every callout you re-type the same details and then have to remember to chase. WOPA generates a plumber's invoice from a WhatsApp message — callout, labour, parts and VAT handled — keeps the numbering tidy, and reminds you to follow up. For a plumber doing several jobs a day, that turns evening admin into ten seconds on the doorstep.
