ToryBoy, I can safely say that is a waste of space!

The requirements for the IMC rating from LASORS state that a minimum of 25 hours
post PPL flying are required.
The exact details can be found in LASORS but flying done before PPL issue doesn't count (exccept for the bit about the instrument training included in the PPL).
Far better to be fully proficient and confident in flying the aircraft in VMC before completing further training.
Personally, I would recomend that at least 50 hours post PPL be completed before starting the course.

PS, If you are fogbound, you will not get flying with an IMC rating - the minimum visibility for departure and arrival is 1800m and in a single you need a minimum cloudbase of 600ft although 1000ft AGL is sensible in a single for the whole route to allow some chance of a fored landing.
There is also the fact that unless you are experienced and in current practice, the above minima should be even higher.
Not as easy as it first seems
