Interestingly, oldest dc didn't have this issue in 2023
This is so true. My eldest was 17 in March 2020 and for him it was getting a slot at a theory centre which was difficult because of the scottish government's rules about social distancing. Through spring/summer 2021 there were kids from here going as far as Brighton and London to sit theory tests. DS had a slot the week before we were going on holiday to Devon and we'd already looked at slots in Exeter if he'd failed. But after that getting a practical test slot in his chosen centre was OK. He failed twice and we managed to get cancellations quite easily, he had tests in January, March and June 2022.
DD was 17 later in 2022 and by then the theory slots were fine, the second she had passed we booked a practical slot in our preferred centre for about 5 months in the future, she sat her test and passed but there was still OK availability for cancellations and moving slots.
Youngest child was 17 in June 2025, he sat and passed his theory the day after his birthday and we spent about 3 weeks looking for a slot. Eventually got one at Shieldhall which is not our local centre, during rush hour. We thought we'd be able to change it but literally nothing came up in the full 6 months we were trying. So he ended up having to do the test, and luckily passed.
This lack of availability has NOTHING to do with the pandemic. It has everything to do with a shit system which allows driving instructors and others to block book tests and this has been exploited by people buying slots and reselling them. There are not enough testers as the salary is barely more than minimum wage and if you have the qualifications, you're better off as an instructor. The only way it;s going to get better is by only allowing learners themselves to book one slot with a theory pass and by recruiting more examiners. This may have to mean that people pay more for tests.
