To prevent contributors here from posting replies which won't apply to Jennyjoan, I'll remind everyone that she's in Northern Ireland.
Unlike in the rest of the UK (where, if one MOT test centre is booked up, one can simply go elsewhere), people in NI can only go to government-run testing centres. (So Jennyjoan can't go anywhere else).
Here's the official position on the backlog in NI:
“The DVA’s advice to vehicle owners who require an MOT to tax their vehicle and cannot secure a date before their MOT expires is to book the earliest available appointment and keep checking the booking system for an earlier appointment.
“If they get to within five days of the expiry date of their vehicle tax and they have been unable to secure an appointment or their vehicle tax has expired, they should contact the DVA Customer Services team at
[email protected] and they will do their best to get an urgent appointment for the vehicle.
“To date, all customers who have contacted the DVA in these circumstances have been offered an earlier appointment.”
