Hi, welcome to the forum, each PCT is different, some expect you to apply for and wait to be approved for funding, others don't.
Each PCT has it's own criteria for WLS...l.so on and so on.
A good place to look is the BOSPA website as there's a pretty comprehensive list of what each PCT requires as its criteria.
Ask away on here, everyone is very kind and welcoming and there's bound to be someone who can answer your questions.
Good luck on your journey.
