If a jump start works, that would mean a fault with the battery or related components. You would need to test the battery voltage in the morning to see if it is holding charge. New batteries can be faulty too.

The other thing to check would be parasitic drains. Something is not turning off and this can be a faulty relay, an electrical component that is faulty or if you have installed any acessories such as power amp etc.

I've been push jumping it not using jump leads would this still mean the battery could be faulty or being drained. All power seems fine. Ie lights are full power all electrics works it just won't make a turning over noise when I turn key it's just silent. Kwik fit recommended a auto electrician to test everything. Would you advise this also? Thanks for your prompt reply

It would depand. Try using jump leads. If possible get the battery voltage readings when it fails to start.

Other things you need to be checking would be the battery terminal connections. Ensure they are clean and secure. Likewise check the ground circuit as well.

One other thing to test would be the alternator charging.

If you have a DVOM, you should be able to perform the basic tests yourself. Getting someone to test might cost you a bomb as electrical faults can be time consuming.
