Everything in one place
Your agreed swap, the requests you have sent, the ones waiting on you, and how your listing looks to everybody else.
If something goes wrong on the call
They didn't answer when DVSA rang
The swap does not happen and neither of you spends a change. DVSA rings the number registered to that booking, so a recent change of number is the usual cause. Agree a new time and try again.
One of us failed the security check
Both tests stay as they are. Have your licence number and booking reference in front of you before you ring, and give details that match the booking exactly.
They changed their mind on the phone
That is their right, and no change is spent by either of you. It is the reason to agree the call properly beforehand rather than ringing on the strength of one message.
DVSA said we'd run out of changes
One of you has already moved the booking twice, and there is no way round it. A third change cancels the booking rather than moving it. Check on GOV.UK before agreeing a swap rather than after.
We're inside 10 working days now
Too late for this pairing. The clock runs to whichever of the two tests is first. Monday to Saturday count towards it; Sundays and public holidays do not. Relist and the board will throw up others.
I didn't get a confirmation email
None is sent. DVSA does not email after a swap. The next reminder about your test carries the new details. To check sooner, sign in to your booking on GOV.UK.
