^^Thanks for the help guys. Think you guys maybe right, the ignition switch does feel a bit "funny", key gets stuck sometimes. I'll have it replaced and see what happens.
Battery was dead after coming back from a two week holiday. I know, I know, have learnt the lesson, will be getting one of those charger things.
One more newbie question, the car has a Giac ecu flash done, now the battery replacement wouldnt' have affected it would it?
