The Santander Easy Access Saver Limited Edition (Issue 3) has a rate of 5.2% AER / 5.08% gross (variable) on savings between £1 and £250,000.

It was launched on Monday last week, offering savers the top-paying rate for the first 12 months after opening the account, which can be done online, via app, phone or in branch.

As it’s easy access, holders can deposit and withdraw cash at any time without fees or restrictions.

One of the big draws of this account – aside from the rate – is that you don’t need to be an existing Santander customer or bank with the lender. Anyone can open the account and save up to £2m, though the 5.2% AER only applies to the first £250,000 held.

At the time of launch, Santander confirmed the account was only available until Sunday 17 September, but could close sooner if there was high demand.

It confirmed the move to withdraw the product early follows “significant demand” as savers look to make the most interest on their money while retaining penalty-free access to their cash.

From tomorrow, Santander’s Easy Access Saver account returns to sale offering 2.5% AER/gross for 12 months.
