I would imagine there's very few jobs available for novice coach drivers.
I've heard £1000 is a typical cost for HGV lessons and test, it's probably about the same for a coach.
That's a lot of money to put up front with little chance of a job at the end of it.
There's always bus driver vacancies.
There's a high turnover of drivers. A few stick at it for life, a lot give it up after a while.
I know First have got their own instructors and examiners.
They will put you through a course of lessons and your test and give you a job if you pass.
The only drawback is that if you leave within a certain time, a year, I think, you have to pay back the cost.
They will only train you on automatics as well, which may limit your job choices if you ever leave to try coach driving, although most modern coaches are automatic anyway.
