Phone bill date - supporting evidence

[b4r1786]

Hi

I have submitted my online application on 7th July. I have phone bill which has it's last date as 14th June 2017. Is my phone bill fine to submit as evidence of contact or should I get a more recent up to date bill?

Preferably the subsisting relationship evidences like phone bill must be highly latest but still the documents not older than 28 days from date of application should be fine.
