How to Change Your Theory Test Date:
(2026 Guide)

Quick answer: To change your car theory test, use the official service at gov.uk/change-theory-test and sign in with your UK driving licence number. You must give at least 3 full working days notice, or you lose your fee and have to book again. Changing is free within that notice. The theory test fee is £23.
Sometimes your theory test date no longer works, and you need to move it. The good news is that changing is free and takes a few minutes online, as long as you give enough notice. This guide covers how to change your test, how much notice you need, and what happens if you miss the deadline.
Key facts at a glance
How to change your theory test, step by step
That is the whole process, and it costs nothing when you give enough notice.
How much notice do you need?
You must give at least 3 full working days notice to change or cancel your theory test without losing your fee. Working days are Monday to Saturday, so Sundays and public holidays do not count. For example, if your test is on a Friday, you need to make the change by the previous Monday to stay inside the window. Leave it later and you lose the £23 fee.
How much does it cost to change?
Changing your theory test is free as long as you give the 3 full working days notice. There is no charge for moving the date within that window. If you miss the deadline, you do not pay a change fee as such, but you lose the £23 you already paid and have to book and pay for a brand new test.
What you need
To change your theory test online you need your UK driving licence number. If you change it by phone or email instead, the DVSA will ask for your full name as it appears on your licence, your date of birth, your address and postcode, your driving licence number, and your booking reference number. The online route is quickest.
What if you need to cancel instead?
If you cannot make the test and do not want to rebook straight away, you can cancel. The same 3 full working days notice applies to get your fee back. If you cancel with less notice, you lose the fee. When you are ready, you book a fresh test and pay the £23 again.
