Are you releasing the throttle when changing gear. Sounds like you're not?

Yea, I am releasing the throttle.

Car does pull on its own if that makes any difference

Also revs on start up, (on its own)

could you perhaps have a vacuum leak somewhere?

spray a load of wd40 around the lines when the engine is running and see if the note changes

On the xe a little silver clip missing on the throttle cable caused it to do something similar.

My old Corsa used to rev it's conkers off, turned out to be a fucked ECU. Hope that isn't the case for yours.

Had it checked for leaks at local garage when it originally broke down - didn't find any, but may be worth giving it a go

Depends what's causing it. Anything that means you have more air that is desired, or less fuel.
