What is the time restriction until you have to pay for the MOT again?
PVR - there is a myth that you can still dive after a failure if the old certificate is in issue, but that's not correct:
From the .Gov website:
Failing the MOT
If your vehicle fails the MOT:
you’ll get a ‘refusal of an MOT test certificate’ from the test centre
it will be recorded in the MOT database
You can appeal the result if you think it’s wrong.
Driving a vehicle that’s failed
You must not drive the vehicle on the road if it fails the test, even if the MOT hasn’t run out, except to:
have the failed defects fixed
a pre-arranged MOT test appointment
