Wouldn't be surprised if all non-ACC training will be eventually outsourced.
Judging by what you get charged at the "non NATS" colleges for an aerodrome + approach ticket (30-40 k), and what NERL charge the units for a trainee delivered from college (xxx k), it's a no brainer for an increasingly cost-cutting stricken NSL !
Good luck to those just starting, or about to start their NATS adventure. Not the best time in history to join a "World Leader in Air Traffic Management"...
Incidentally... what do the several Band 5 instructors and "above band 5" training delivery managers do while there's no training being delivered ??
