100% mortgage and deposit?

We are hoping to purchase our first home and I was just wondering if anyone knows how long it has taken the deposit with an 100% mortgage to reach the EA. ?? The bank has completed the valuation and are sending the loan drawdown form to our solicitor which we will sign hopefully tommorow. I know this form then goes back to the bank.

usually takes 3 to 5 working days from when you return it to the lender

thank you for quick reply - a few more sleepless nights so!
