The van is your best salesperson, until it isn't
If you're a UK plumber, sparky, chippy or gas engineer, your mobile number is probably painted on your van in six-inch vinyl. It's the cheapest lead generation on earth. Every parked job, every trip to the wholesaler, every school run in the transit becomes a potential customer.
It also becomes something else, if you've been doing it long enough:
For years the answer was: put up with it, it's the price of the leads. But something shifted in 2024-25. Between mobile number-porting scams, the rise of AI voice cloning, and just general burnout, UK trades are finally asking: is there a version of this that doesn't require me to give my personal mobile to every passer-by?
There is. And it's not what most tradesmen assume.
What most people try first (and why it fails)
Option 1: Second mobile / burner phone
You buy a second handset and a £10/month PAYG SIM. All work calls go there. You switch it off at 6pm.
Why it fails: You now have two phones to carry, two batteries to charge, and you'll forget which one is which. Worse, if you use the same number for years, customers screenshot it and pass it round WhatsApp groups. The second number becomes as leaky as the first within 18 months.
Option 2: A landline / VoIP number (0333, 0800)
You buy an 0333 or 0800 number that forwards to your mobile. You paint that on the van instead.
Why it fails: 0333 numbers cost money to call (or at least look like they do — many mobile plans include them free but customers don't know that). Response rates drop. Trust drops — buyers assume you're a call centre.
Option 3: A booking app (Checkatrade, MyBuilder, Rated People)
You stop putting any number on the van at all. All leads go through the platform's messaging system.
Why it fails: You now pay 5-15% commission on every lead. You're competing with 30 other tradesmen for the same job. The platform owns the customer relationship.
Option 4: WhatsApp Business
You put your WhatsApp Business number on the van.
Why it fails: WhatsApp Business is genuinely useful, but the number itself is still visible to everyone. Once it's out there, it's out there.
The problem underneath all these
Every one of the above shares the same flaw: your contact detail is public and permanent. Once your number is on the side of a van seen by 5,000 people a week, it's out of your control forever. Every one of those 5,000 can save it and call you at 11pm three years later, post it on Facebook groups, sell it to scam callers, share it with an ex-partner or debt collector, or use it against you in a review site.
The moment you paint it on the van, you've made a permanent choice about your own privacy on behalf of every future stranger who sees your van. If this rings true, our guide on how to protect your phone number's privacy in the UK explains the bigger picture.
What UK trades are doing instead in 2026
Three approaches are gaining traction, and they combine well.
1. A QR sticker on the van instead of a phone number
This is the biggest shift. A small QR code sticker in the corner of your rear window, or on the driver's door beneath your logo. Anyone can scan it with their phone camera (no app for them to download). It opens a message page with your company name and a few preset messages: Get a quote, Ask about your service, Blocking access — please move. They tap, type a note, hit send. You get a WhatsApp with their message and their location.
They never see your phone number. If someone becomes a nuisance, you block them and it doesn't leak your number to anyone else.
This is what TapReach fleet stickers do — £4.99 per sticker plus £2.99/month per vehicle. You get a dashboard showing every scan, every message, and where they came from. UK-made in Manchester. See our full comparison of QR stickers vs dashboard notes.
2. A professional hours landline that forwards to WhatsApp during work hours only
For trades who genuinely want a phone number visible, a call-forwarding service lets you set business hours. Outside those hours, callers get a professional voicemail: Thanks for calling MacKay Plumbing. We're closed until 8am. For emergencies, message our WhatsApp on the number on our website. Otherwise please leave a message.
Cost: £5-15/month per number. Setup: 20 minutes.
3. Web form only for cold enquiries
You put your website URL on the van, not any phone number. All first-contact enquiries go through a web form. Existing customers get your direct number after the first job.
This works better than it sounds. Modern QR codes make website URLs painless to reach — just scan and go.
The maths on TapReach specifically for trades
For a five-vehicle plumbing outfit, the numbers work out like this.
Old way: Personal mobile on all five vans. Free upfront, but around 30% of calls are wasted (out of hours, scam, timewasters, wrong number). At 8-10 calls a day per van, that's 12-15 wasted calls a week per driver. Add one bad-review incident a year and one lost customer to spam-marking = roughly £600-1,200/year of lost revenue per van, plus the intangible cost of being permanently on-call.
TapReach fleet: 5 stickers × £4.99 = £24.95 one-time. 5 vehicles × £2.99/month = £14.95/month = £179.40/year. Total year one: £204.35.
Payoff: almost immediate if it prevents even a couple of out-of-hours confrontations, one bad review, or one lost job to spam-block. Plus everyone in the van gets their evenings back.
You keep your existing WhatsApp Business number for repeat customers (they've earned direct access). You use TapReach for cold leads (they haven't).
But what if I actually want people to call me?
Fair point. Some trades — 24-hour emergency plumbers, locksmiths — genuinely need calls, immediately, from strangers. In that case a masked call service is what you want: the caller gets connected to you, but they never see your number. TapReach's Smart plan (£2.99/month) includes this.
The point isn't don't be reachable. It's don't hand out a permanent copy of your identity to every stranger who ever sees your van.
The bigger shift
In 2015, painting your mobile on the van was smart. In 2026, it's the digital equivalent of leaving your front door unlocked because your street feels friendly. It works right up until it doesn't.
The trades who'll still be enjoying their evenings in 2030 are the ones making this switch now. Cheap, low-effort, reversible. A £4.99 sticker on the van and a £2.99 monthly subscription. If you don't like it, the sticker peels off and you're back where you started.
Or you keep your mobile on the van, and you keep taking the 11pm calls.

FAQ
Should I put my mobile number on my van in 2026? Only if you're happy for 5,000+ strangers a week to have it permanently. A QR sticker gives them a way to reach you without ever seeing your number. Both work — the sticker is just reversible.
What's the cheapest way to hide my personal number for business calls? A £5/month VoIP number (Numbergroup, Callroute) that forwards to your mobile during business hours. Or a QR sticker at £4.99 one-time plus £2.99/month covers the same job with more privacy.
Can customers still reach me in an emergency without my mobile number? Yes. Masked call services (like the one TapReach Smart includes) let callers dial you directly while your number stays hidden. They see a relay number, you see the call ring.
