Earths ok? I'd double check the alternator with a multimeter.

Run the engine and check the battery with a multimeter. You can get them at loads of places like Maplin, even Argos sell them but it costs twice as much for the same thing. If it is reading somewhere between 13 and 15 volts then the alternator is fine. 
 
Stop the engine then test the battery again. If it stays at around 12.5v then it has charged, if not then it is not charging correctly. If it starts dropping then the battery is either not holding charge or there is an electrical issue somewhere on the car that is causing power to be drained. 
 
It may just be a case of that the battery needs replacing. Don't go to Halfords as it's an utter rip off. Go to a local motor factors and you'll get one for half the price.

Did it stay at 12.5v as Dave said when the engine is stopped?

hmm a strange one, I'd still try it when its not running, all I can think is the battery is knackered.
