Should I charge a callout fee?

Most plumbers do, and customers expect it. The usual approach is a fee that covers travel and the first hour on site, then an hourly rate after that. Say which it is on the invoice.

How do I invoice for emergency work?

Bill the out-of-hours rate as its own line rather than quietly inflating the hourly figure. A line reading 'Emergency callout — Sunday' is understood; an unexplained higher rate looks like a mistake.

Should I mark up parts?

Standard practice, and legitimate — you carry the stock, the sourcing time and the warranty. Whether you show the markup or price parts inclusively is your call, but be consistent.

When should a plumber be paid?

For domestic work, on completion or within 7 days. For letting agents and commercial clients, Net 30 is common. For larger jobs, staged payments with a deposit for materials up front are normal and protect your cash.

Should I invoice the tenant or the landlord?

Whoever instructed the work, and confirm it before you start. A tenant can call you out, but if the landlord is paying, the invoice must be addressed to the landlord or their agent, with the property address shown separately. Getting this wrong is the most common reason plumbing invoices sit unpaid between two parties who each think the other owes it.

How to bill for plumber work

Separate parts from labor

Customers query a single large number far more often than an itemised one. Splitting them also makes warranty conversations simpler later.

Put the callout fee on its own line

It is the charge most often disputed. Naming it, rather than folding it into the first hour, prevents the argument.

Note the work address if it differs

Landlords and letting agents pay for work at addresses they do not live at. Put the property address in the notes or nobody can match the invoice to the job.

What belongs on a plumbing invoice

The property address the work was done at, if it differs from the billing address
The date of the visit — landlords reconcile against tenant reports
Callout or first-hour charge as its own named line
Labor hours at your stated rate, separate from parts
Each part listed with quantity, so the customer can see what was fitted
Any parts warranty and its length, in the notes
Gas Safe, licence or registration number where your jurisdiction requires it
