BAE systems advanced apprentice age 34

Hi all going through the application process at the moment for advanced apprentice scheme at bae systems. I am age 34 and already been previously city and guilds qualified. Does anyone know what the pay scales are? If they are different for older people on the schemes or generally just what are the payscales? It will be based at portsmouth naval base. Hopefully aiming to do welding and fabrication which I am already qualified in.
