Metro Bank online application for savings

I've opened a few of these over the years but have a current account with them which had to be opened in store in those days so can't give you much help for new online accounts. However I had a problem opening a fixed rate saver last summer. They say you can deposit in several tranches but my second one, a day later than the first, was refused. I had to close the saver, open a new one and make a single full deposit from my current account. Perhaps it was a problem because I used my current account and you'll be fine with the instant access account but one to watch for

Edit: I imagine your term will start when the transfer to the Fixed Term Savings Account takes place and not the application date

Opening an account online If you open your account online, an Instant Access Savings Account will be opened automatically for you. Money from this account will be transferred into your Fixed Term Savings Account.
This will be done either:

• once you’ve paid in at least the minimum amount you’ve agreed to deposit in your Fixed Term Savings Account
• after 30 days of opening the account if you’ve paid in less than the minimum amount you've agreed to deposit
