UK CLEAN AIR ZONES

Never miss a Clean Air Zone charge again.

HOW IT WORKS

Set it once. Drive normally.

CAZ Tracker does the watching so you don't have to remember which towns charge, or when.

1

Add your vehicles

Enter your registrations. CAZ Tracker knows which zones charge your vehicle and which give it a free pass.

2

Drive as usual

The app watches your location in the background. Cross into a Clean Air Zone and it logs the crossing instantly — no tapping required.

3

Get reminded to pay

One clear notification per zone, per day, with a direct link to the official payment page. Mark it paid and it's off your list.

FEATURES

Built for people who drive for a living.

📍

Automatic zone detection

GPS-based entry and exit detection using official zone boundaries. No manual check-ins, no guesswork about where the line is.

🔔

Smart pay reminders

One alert per zone per day with a direct pay link — never a barrage of duplicate notifications for the same trip.

🚐

Multiple vehicles

Run a van and a car? Add both. An optional Bluetooth beacon tells the app which vehicle you're in, so only the chargeable one triggers alerts.

🔎

Compliance check

Look up any registration to see whether it's charged in each zone before you set off — so there are no surprises.

🗂️

Crossing history

A tidy log of every zone you entered and whether it was paid — handy for expenses and reconciling charges.

🔋

Light on battery

Efficient background monitoring designed to sip power, not drain it, on a full day of driving.

QUESTIONS

Good to know.

Does CAZ Tracker pay the charge for me?

No — it reminds you and links you straight to the official government payment page for that zone. You stay in control of every payment.

Will it drain my battery running all day?

It's built for exactly that. Background monitoring is designed to be efficient across a full working day of driving.

What if my vehicle is exempt?

Add its registration and CAZ Tracker will know which zones don't charge it — so you won't get pointless reminders for zones you drive through for free.

How does it tell which vehicle I'm driving?

If you have more than one vehicle, an optional Bluetooth beacon left in the chargeable one lets the app detect which you're in, so alerts only fire when they matter.

When can I get it?

Now, on both — get it on Google Play or download it on the App Store. Your first 7 days are free; after that it's £12 a year, bought here on the website or in the app.
