Is there a difference between pay as you go and black box car finance?

Are you considering financing a car but worried about your credit score or the rigidity of traditional car loans? You might have come across two innovative options: Pay As You Go (PAYG) car finance and Black Box car finance.


Both types of finance unique solutions tailored to those who need more flexible payment options, but they come with their own sets of features and considerations. Let’s dive into the differences between PAYG and Black Box car finance to help you decide which might be the best fit for you.

What is PAYG car finance?

Pay As You Go car finance, often referred to as PAYG, is a type of loan where the vehicle is fitted with a device that allows the finance company to disable it if payments aren’t made on time. 

This finance method is designed to provide an easier approval process for individuals who might struggle with traditional car loans due to poor credit history.

When you take out a PAYG car loan, a small device is installed in your car. Each time you make a successful payment, you receive a code to keep the car operational until the next payment is due. If you miss a payment, the device will disable your vehicle until the payment is made.

Ideal candidates for PAYG car finance

Ideal candidates for PAYG car finance include individuals with poor credit history who struggle to get approved for traditional car loans, those needing a strong incentive to make timely payments due to the risk of car immobilisation, and people looking to rebuild their credit score through regular, on-time payments.

What is black box car finance?

Black Box car finance involves fitting a small device, often called a black box, to your car. This device connects to the car’s internal computer and communicates with your lender using general packet radio service (GPRS) functionality. 

Unlike PAYG, Black Box finance often focuses more on reminding you about payments and less on immediate vehicle immobilisation.

The black box tracks your payments and provides reminders. A few days before a payment is due, a green light on the box turns red and starts flashing. 

If you make the payment on time, you receive an activation code to reset the box to its green state. If you fail to make the payment, the car may eventually be disabled after a grace period.

Who benefits from black box car finance?

Black Box car finance is beneficial for high-risk borrowers who have past credit issues, individuals needing structured payment reminders to ensure timely payments, and those looking to rebuild their credit score by making consistent, on-time payments. 

This type of finance provides an added layer of assurance for lenders, making it easier for borrowers with poor credit histories to secure vehicle financing.

Key differences between pay as you go vs black box finance

Technological aspects

When comparing the technological aspects of PAYG and Black Box car finance, PAYG utilises a basic immobiliser device installed in the car, which primarily functions to disable the vehicle if payments are missed. 

This system relies on manual payment tracking, where you receive a code to keep the car operational after each successful payment. 

In contrast, Black Box car finance incorporates more advanced telematics technology, involving a device that not only connects to the car’s internal computer but also communicates with the lender via GPRS. 

This black box offers automated payment reminders through visual signals and can remotely disable the vehicle after a grace period if payments are not made. 

Additionally, the black box system can provide lenders with more detailed oversight of the payment status, though it typically does not track driving behaviour. 

This technological difference means that PAYG offers a more straightforward, immediate response to missed payments, while Black Box finance provides a structured, technologically integrated approach to managing car finance.

Payment management

Payment management in PAYG car finance involves a system where, after each successful payment, you receive a unique code that must be entered into the vehicle’s immobiliser device to keep the car operational. 

If a payment is missed, the car is immediately disabled, which ensures strict adherence to the payment schedule but can cause significant disruptions to your daily life if you fail to pay on time. 

On the other hand, Black Box car finance utilises a more lenient approach by providing automated reminders through a device installed in the car. 

This device signals a few days before the payment is due, often with a flashing red light, and if the payment is not made, it may eventually disable the vehicle after a grace period, typically 30 days. 

During this grace period, borrowers have an opportunity to arrange the necessary funds, reducing the immediate impact on their mobility. 

This structured reminder system helps borrowers stay on track with payments while offering some flexibility in case of financial difficulties.

Impact on daily life

The impact on daily life between PAYG and Black Box car finance can be quite different due to how each system handles missed payments. 

With PAYG car finance, the immediate consequence of a missed payment is the vehicle being disabled, which can disrupt your routine, especially if you rely heavily on your car for commuting to work, running errands, or other essential activities. 

This can be particularly stressful as it leaves little room for financial missteps. In contrast, Black Box car finance provides a more flexible approach, offering automated reminders before the payment is due and a grace period after the due date. 

If you miss a payment, the black box device will start flashing a red light and send reminders, allowing you time to arrange for the necessary funds without immediate immobilisation. 

This grace period can significantly reduce the stress and inconvenience associated with missed payments, making it easier to manage financial hiccups without severely impacting your daily life. 

However, if payments continue to be missed, the vehicle will eventually be disabled, similar to PAYG, but with more warning and time to rectify the situation.

Privacy concerns

Privacy concerns differ between PAYG and Black Box car finance due to the nature of the monitoring devices involved. 

PAYG car finance employs a basic immobiliser device that focuses solely on payment tracking and immobilisation, with minimal data collection beyond whether payments have been made on time. 

This system provides a straightforward, less intrusive method of ensuring payments are kept up to date. In contrast, Black Box car finance involves a more sophisticated telematics device that connects to the car’s internal computer and communicates with the lender using GPRS. 

While the primary function of the black box is to monitor payments and send reminders, the level of oversight can be perceived as intrusive by some borrowers. 

Although these devices do not typically track driving behaviour like those used in insurance telematics, the continuous communication and monitoring required to ensure timely payments might raise concerns about data privacy and the extent of lender oversight. 

This heightened level of monitoring, despite its benefits in preventing missed payments, can make some borrowers uneasy about their privacy and the potential for misuse of collected data.


Choosing between Pay As You Go and Black Box car finance depends largely on your personal circumstances and preferences. 

By understanding the key differences, advantages, and disadvantages, you can make an informed decision that best suits your needs. 

Whether you opt for PAYG or Black Box car finance, both paths lead to the potential of improved credit and greater financial stability in the future.
