As you have a degree and some experience you could try the NATS Direct Entrant Graduate (DEG) scheme. It has been running for some time (I joined 10 years ago via this route) and is IET accredited. I think as we have just finished interviewing that entry is closed for 2009, and as such it is probably not on the NATS website at the moment.
The EngTech scheme is aimed really at HNC/HND level for a more hands role, so it depends on what you want to get into, and if you can wait for the DEG scheme recruitment for 2010 to open up later this year.
