Nationwide Building Society has implemented a rule change that could provide customers with up to £4,800 in additional savings. The mutual, which operates branches in Birmingham, announced revised ISA rates this week.
New Fixed ISA Rates
The one-year fixed cash ISA now pays 4.5% AER, while the two-year version offers 4.55% AER. For those willing to commit for longer, both the three-year and five-year fixed ISAs provide a top rate of 4.6% AER. These changes come as Nationwide competes with major banks such as HSBC UK, Santander, Lloyds, NatWest, and Barclays.
Potential Earnings for Savers
According to Finder, the average UK saver has £19,214 set aside. Depositing this amount into Nationwide’s one-year ISA at 4.5% would yield £860.58 in tax-free interest over 12 months. Choosing the three-year fixed rate at 4.6% would generate £2,762.37 over the full term, while the five-year option would return £4,822.23.
Richard Stocker, Head of Savings at Nationwide, commented: “We are pleased to launch new higher rates across our Fixed Rate ISA range, offering both short- and longer-term options. For those requiring more flexibility, we also have our Triple Access offering. All ISAs and rates are available in branch, by phone, or online, as we know customers value choice in how they bank. That is why we have extended our Branch Promise. Customers can also use our in-app budgeting tool to help manage their money.”
