Since then (a week ago now) I have seen the pressure drop to zero, within 2 days.
The is no *obvious* leak, there have been no changes, except I have bled the rads.
Am I missing something here?
We have had to to have the mechanical peice (I know not the name) that switches between service to the rads OR the hot water replaced *every* year for the last 4 years!
Yes the system is only 4 years old!
Thanks,

Check a couple of things
1/Look outside at the pressure relief valve outlet. Is it dripping?
2/What happens to the pressure when the system is hot? Does it go up above 2.5 bar?
post result and we'll talk through what to do next.
