Rescheduling on hold driving tests
When you or your pupils book tests via the GOV.UK online booking service you have the option to put your booking on hold if there are no suitable available tests.
The on hold option should only be used for booking tests:
If tests are placed on hold for any other reason, the application will be cancelled, and the test fee refunded.
A large number of car test bookings are currently on hold in our system which do not fall into the options above. These tests have been put on hold by the person who booked the test, and we are now asking them to choose a test appointment.
We will be contacting anyone with a booking on hold to let them know that they need to choose a test date by the end of Tuesday 31 August 2021.
We are continuing to add new test slots, so if your pupil cannot find a test initially, please encourage them to keep looking regularly. It is important that you talk to your pupils ahead of them choosing a test date so you both discuss if they will be ready for their test.
If they do not choose a test slot by the end of Tuesday 31 August 2021, we will cancel their on hold booking and issue them a full refund.
If your pupil no longer wants a car practical test they can cancel a driving test online. They’ll then get a full refund within 15 working days of cancellation.
If you have booked any practical tests for your pupils using the book and manage your pupils test service that are still on hold, an email will be sent to the email address that you gave at the time of the booking.
We are working to update the online booking system to make it clearer how the on hold button should be used during the booking process.
