L322 Supercharged starting issues

Hi.
My 2005 Range Rover supercharged has a intermittent fault when trying to start. I put the key in the ignition, all the dash lights come on then turn the key and nothing happens. I have tried in park and neutral. Normally I have to leave it a while or keep trying and eventually it will start. I am a new Range Rover so don’t know much about them yet.
If anyone can help
Thanks.

Could be battery is low, alternator/starter/connections, loose terminal
Does it make a click under the bonnet when you turn the key or nothing?

Try to check the simple stuff first before diving in deep. Something will usually come to light when checking

Hi. Don’t get any noise when doing final turn of the key.
