Nationwide members who take action straight away could end up more than £19 better off compared with those who postpone a particular move.
The offer is exclusive to those who hold an account with Nationwide. Emails sent to customers in recent days read: “As a Nationwide member, we’re delighted to be able to offer you our best available fixed savings rate.
“Earn 5% AER/gross a year (fixed) for 15 months on balances up to £10,000 with our Member Exclusive Bond.”
Additional information on the Nationwide website confirms that those who open this account can deposit up to £10,000 for 15 months.
Money can only be added within the first 14 days of opening the bond, and the account may be held either individually or jointly.
Once the bond has been opened, no withdrawals will be allowed until the complete 15-month term has passed.
However Nationwide confirms that by keeping your money untouched for this period, you could earn a free £63.13 for every £1,000 saved. That’s £631.30 if you deposit the maximum £10,000.
However, you’ll only receive this sum if you deposit the full £10,000 on the opening date.
If you wait until day 14, Nationwide said, you’ll earn £61.18 in interest per £1,000, or £611.80 if you deposit £10,000. That’s some £19.50 less than if you deposit the funds immediately.
Nationwide added: “At the end of the 15 month term, we will move your money to an instant access savings account. We will let you know before this happens and what your interest rate will be.”
To be eligible for the account, applicants must be a UK resident aged 16 or over and have held Nationwide membership as of May 20, 2026, while remaining a member at the point of opening the bond.
Membership covers anyone with a mortgage, savings account, or personal current account with either Nationwide or Virgin Money.
Applicants must also be registered for Nationwide internet banking and hold a valid email address.
