What rubbish all cossie do it!!
It could be the alternator, even if new, simple way to find out disconnect the main feed overnight.
Some alarms can draw a lot of current, but unless the alarm has been changed and it was ok before it won't be this.
To find a drain the easy way, full charge the battery, pull all fuses connect a buzzer between battery post and battery lead(positive) the buzzer will sound a certain volume which will alter when a fuse is replaced that has a draining load on it.
You can of course use a metre for this, but have to keep watching all the time, whereas a buzzer just listen so it's a lot quicker.
You will have a few circuits that draw current ie radio/alarm etc, but you will hear the highest pitch change of the one drawing the most.
Make sure you leave a window open, or the keys out of the car, and ignition off when doing this, doors shut.

its maybe the fan control switch at the bottom of the rad, thought this was a common reason for battery running flat. at about £8 its worth replacing anyway at summer.
