Few weeks ago my batterykept going dead if i didnt drive it for a couple of days, so i changed the battery thinking it was just old. 
 
The problem persisted and now does it nearly everyday. 
 
I've noticed aswell, when i open my door to get in, the interior light flickers like theres a dodgy connection somewhere. 
 
Any help with be grateful

Check the alternator output firstly. 
 
Also, possible a faulty earth somewhere.

Alternator doesn't hold a charge, the battery does.

Which earths would you be checking first? 
 
After not using my car for a day the battery is completely dead to a point that my central locking doesn't work and m interior light doesnt come on.

Tis ok, you reckon it could be a dodgy earth then? If so, where would you start?
