How to invoice a plumbing job
Most plumbing invoices are built from three things: a call-out or visit charge, your time on site, and the parts you fitted. Keep them on separate lines. Customers query a single "plumbing work – £340" line far more often than an itemised one, and if you replaced a radiator valve and a length of 15mm copper, saying so makes the price feel fair.
For labour, bill in hours or half-hours and say which. If you charge a higher rate for evenings, weekends or emergency call-outs, add that as its own line so the customer can see why the total is higher than they expected.
Parts and materials
List the main parts by name, such as "Grohe kitchen mixer tap" or "TRV pair". Smaller fittings like olives, PTFE tape and solder can go on one "sundries" line. If you're VAT-registered, VAT is charged on parts as well as labour, so include them in the same invoice rather than passing on the merchant receipt.
Gas work and certificates
If the job included gas work, such as a boiler service or a new gas hob connection, it's useful to put your Gas Safe registration number in the notes and say whether a certificate or service record has been left with the customer. It answers the question before they ask it.
Getting paid
Send the invoice the same day while the job is fresh. Put your bank details in "How to pay you" and ask the customer to use the invoice number as the payment reference, so you can match payments in your banking app without guesswork.
Frequently asked questions
Should a plumber charge VAT on an invoice?
Only if you're VAT-registered. You must register once your taxable turnover goes over £90,000 in a rolling 12 months. If you're not registered, leave the VAT box unticked and don't add VAT to your prices.
What must a UK invoice include?
A unique invoice number, your business name and contact details, the customer's name and address, a description of the work, the date the work was done, the invoice date, the amounts charged and the total owed. This template has a field for each of them.
Can I invoice for a call-out if I couldn't fix the problem?
Yes, if you told the customer about the call-out charge before you attended. Describe what you did, for example "Attended, diagnosed failed diverter valve, part ordered", so the charge makes sense.
