Had an auto electrician out to look at this today, turned out to be my interior light circuit so can just pull fuse number 10 out and battery drain drops from 200mA to around 55 (30 is alarm and 25 just general old s**theap drain).
I'm guessing that when I tested this I must have done something wrong which is annoying because I could've saved myself a few quid but you live and learn I suppose.
Unfortunately he wasn't able to find the exact culprit in the time he had to look at it but for now I can live with just pulling this fuse out when I'm not using the car.
Cheers for the advice.
