WHV “cleared funds” requirments/strictness

Hi all,

Apologies if this isn't the correct place.

Myself and my girlfriend are applying for WHV from UK.

I see that the requirement is to have £2.5k in cleared funds with 3 months bank statement. I have this across different banks on closing balance for every three months but my girlfriend's drops down to around £2k in one of the three months. We both have over £10k consistently in ISAs. I was wondering if the requirement is strictly have £2.5k in ever single closing balance for the three months? Failing this, can ISAs/ current balance etc be considered?

Cheers
