(I'm assuming you have a Corsa hatchback, so this is easy to check either by tilting the rear seat backs forward or removing the rear parcel shelf so you can see into the luggage compartment when the hatch is closed. If your car has a real boot you will have to find yourself a trusting soul who is prepared to climb into the boot and let you then close it to see if it goes dark!). Another possibility could be a light in the glovebox not going out, but this is more difficult to check. Either of these staying on overnight would be enough to flatten your battery.

This rings true with problems on our car previously.
Had some bodywork done, and the rear hatch (estate car) was left open overnight after the paint was baked. The battery was in good health before the work, but the draining of the battery completely killed it. Only fixed by a new battery being installed.
