QR Codes for Plumbers

Your van sits outside a house for three hours. Make it do something.

A plumbing business runs on repeat calls and referrals, and both depend on a customer being able to find you again six months later. A QR code turns the three things you already leave behind - the van parked on the street, the invoice on the kitchen table, the service tag on the boiler - into a one-scan route back to your booking form. Make it dynamic and the same printed code can point at a booking page today, an emergency number over the winter, and a review request the week after a job.

Why use a dynamic QR code for this

The van becomes a booking form

A code on the rear door or the side panel gets scanned by neighbours while you are inside on a job. That is free local advertising you already paid for.

Reviews while the job is fresh

A code on the invoice, pointed at your Google review page, catches the customer in the hour they are most pleased with the work.

Service tags that call you back

A sticker on the boiler or the stopcock with a code for booking the next service turns a one-off install into an annual job.

How to set it up

1
Choose the destination: booking form, phone number, or your Google review page
2
Generate a dynamic QR code and put it on the van, the invoice template and your service stickers
3
Repoint it by season - emergency callout in winter, boiler servicing in autumn

Before you print it

If your plumbers code may ever need to point somewhere else, create it as a dynamic QR code you can edit after printing. The printed pattern never changes; only the destination behind it does. It also means you can track every scan by day, device, and location and see which placement actually worked.

Plumbers FAQ

How big does the code need to be on a van?

Bigger than you think. A code reads from roughly ten times its own width, so a 15 cm code is good for about a metre and a half - fine for someone standing at the kerb. If you want it scannable from across the street, you are into 40 cm and it competes with your phone number for space. Most plumbers do better with a large phone number and a hand-sized code by the rear door.

Will it scan off a dirty or wet van?

Road film is the real enemy, not rain. Keep the code on a panel you wipe, leave a generous white margin, and avoid putting it low on the back doors where spray collects. A matte laminate helps more than a gloss one because it kills the glare that stops a phone focusing.

What should the code point at - my website or my phone?

A booking or contact page, in most cases. A code that dials straight away feels aggressive on a van, and someone scanning at 8pm wants to leave a message rather than ring you. On an invoice, point it at reviews instead: the job is done and the ask is different.

Can one code do all three jobs?

One printed code, yes, if it is dynamic - but not at the same time. Use separate codes for the van and the invoice so the scan data tells you which is working, and repoint each as the season changes.

How big should I print the code?

Roughly a tenth of the scanning distance: about 2 x 2 cm for arm's length, bigger for anything read across a room. Leave a clear white margin and test-scan the proof before a print run.
