Yes, initial training (9-11 months) is in Bournemouth and you will have been put on either an Area or Aerodrome course.
After that you can be sent anywhere in the country (you must sign to agree to this at stage 1!). In all probability it will be either Swanwick or Prestwick if you are on the Area side, and more people do Area. If you are on Aerodrome then you could be sent to any NATS controlled aerodrome.
