Evidence required for EC

[cuberoot]

Hi

I would like to apply for EC soon, but I am not sure what evidence I require for a successful application.

Application details:
In country application
No spouse
No dependants
Currently employed in UK

I only recently obtained my own UK bank account and I only recently obtained a job, so I do not have historical bank statements. I have seen on this forum that a bank balance of £1500 GBP and a letter of employment should be successful. So will my application be successful if I show 1 month bank statement with a balance around £1500 and letter of employment?

I would appreciate answers or if somebody could point me in the right direction?

Thanks.
