Step One: Firstly, the KenBuster tracks your vehicle and logs any breach of the congestion zone area. If your car hasn't entered the zone it'll send you a text message and/or email to let you know that no action has been taken.

Step Two: If it decides that your vehicle has breached the congestion charging area, and it's at a chargeable time and day, the KenBuster will make an automatic payment to TFL for the amount due. This payment is deducted from the payment type you selected when you registered with the KenBuster company.

Step Three: Finally the KenBuster will send you an SMS notification and/or an e-mail receipt as confirmation of your payment.

At any time you can also log into our website and view your transactions on a secure part of the site. On this page we'll show you the date and time you entered the zone, how much payment was for, and receipt for each transaction.

How do I fit the KenBuster in my vehicle?

Simply plug it into your cigarette lighter. And don't worry if you have other devices to plug in - adaptors to convert the one cigarette lighter into multiple sockets are available.
