Catch every road charge without handing your card to anyone.
Dart Charge, London ULEZ, the Blackwall and Silvertown tunnels all use cameras, not barriers, so it's easy to drive through and forget. ChargeGuard spots the crossing on your phone and reminds you to pay, in time. No card linked. No number plate shared. Nothing leaves your device.
- No card linked

"Isn't there already auto-pay for this?"
Yes, and if you're happy to link your card to an auto-pay account, that's often the simplest option. It pays the charge for you automatically.
But auto-pay means giving a company your card and your number plate, and letting them charge you whenever their cameras see you. A lot of people who only cross occasionally don't want that. They'd rather just be reminded, and pay it themselves.
That's who ChargeGuard is for. It watches for the crossing on your phone, reminds you, and then gets out of the way. It never sees your card, never sees your plate, and never takes a payment.
Auto-pay
Convenient- Links your card
- Shares your number plate
- Charges you automatically when cameras see you
Simplest if you cross often and don't mind the trade.
ChargeGuard
Private- No card, ever
- No number plate shared
- You pay the official service yourself
For occasional crossings where you'd rather stay private.
Knowing free auto-pay already exists, would you still want a private reminder instead?
A small forgotten charge becomes an expensive penalty.
These roads charge by camera, with no barrier and no reminder. So it's easy to:
- drive through without realising it was chargeable,
- mean to pay later and forget,
- be unsure whether you were even detected,
- and get a Penalty Charge Notice weeks later, often around ten times the original charge.
ChargeGuard is a reminder and journey-detection tool. It doesn't pay charges or issue or cancel fines, and it can't catch every crossing. You stay responsible for checking and paying official charges. What it does is give you a clear nudge while there's still time to act.

Penalty amounts vary by scheme, but a forgotten charge routinely lands as a fine many times larger.

What we're planning to build.
Early thinking, shaped by the waiting list. Nothing here is a promise. It's the shortlist we want your steer on.
- On-device journey detection
- Deadline countdowns
- Reminders timed before the deadline
- "Paid" confirmation so reminders stop
- Multiple vehicles
- Payment history
- Supported-zone info
- Full control over location permissions
ChargeGuard won't issue, cancel or guarantee anything, and can't promise every chargeable journey is detected. You remain responsible for official payments.
Built to know as little about you as possible.
For this product, privacy isn't a footnote. It's the whole pitch. Each promise below only ships once the build genuinely does it.

ChargeGuard never takes a payment. You pay the official service directly.
No number plate shared.

Would you actually use (and pay for) this?
A few quick questions. Anonymous, no email needed. The last one is open. That's where the real objections live, and we read every answer.
Questions, answered honestly.
Does ChargeGuard pay charges for me?
No. It detects a likely crossing and reminds you to pay through the official service yourself. It never handles your money.
Why would I use this instead of auto-pay?
Auto-pay is great if you're happy to link your card and let a company charge you automatically. ChargeGuard is for people who'd rather stay private and pay themselves. It never sees your card or plate.
Can it guarantee I'll never get a fine?
No. Detection depends on your phone's permissions, signal, and technical limits. You stay responsible for checking and paying. It's a reminder, not a safety net.
Which charges will it cover first?
The planned first version focuses on the Dartford Crossing, London ULEZ, and the Blackwall and Silvertown tunnels.
Will it track me all the time?
No. Detection is designed to run on your device and to use as little location data as possible. You control the permission and can switch it off.
Is this official / connected to TfL or National Highways?
No. ChargeGuard is an independent tool and isn't affiliated with, endorsed by, or connected to TfL, National Highways, or any charging authority.
When does it launch?
Not confirmed yet. Waiting-list members get invited to test before public release.
