Hi ATC-Wanabie,
I would try the NATS option first. It's only a 4.5 hour drive to Liverpool, so you could go home at weekends. Not sure about your age though, you might just be borderline. But your background should certainly be an advantage, radar after all, is just a big video game. NATS opens up a few more options for an ATC career also, with a good choice of airports and en-route centres.
Going through your local airport means starting at the bottom and working up to the point where your employer decides if it's worth their while training you up as a controller. Mind you, an assistants job can also be very interesting too.
If you haven't done so already, pay a visit to a few ATC establishments and see what you think of the job.
Whatever you decide, the best of luck to you.
On the beach, (after 35 years as an ATCO)
