Nationwide has introduced higher rates across its fixed-rate Cash ISA range, with customers able to earn up to £4,822 in tax-free interest over five years. The changes came into effect this week and apply to several savings products offered by the building society.
The updated rates include a one-year fixed Cash ISA paying 4.5 per cent AER and a two-year option paying 4.55 per cent AER. Nationwide said the highest rate available is 4.6 per cent AER, offered on both its three-year and five-year fixed ISAs. The changes also mean older versions of these accounts are no longer available to new customers from 6 May 2026 onwards. According to Nationwide, the revised rates are available online, by phone and in branch.
Fixed ISA Rates Increase Across Multiple Terms
Nationwide said its latest changes cover short- and longer-term savings products, with rates varying depending on how long customers are prepared to lock away their money. The one-year fixed Cash ISA now pays 4.5 per cent AER tax-free, while the two-year account pays 4.55 per cent AER. Both the three-year and five-year fixed-rate ISAs offer 4.6 per cent AER tax-free.
According to Finder, the average UK saver currently has £19,214 set aside. Based on those figures, someone depositing that amount into Nationwide’s one-year ISA at 4.5 per cent would receive £860.58 in tax-free interest over 12 months.
The same deposit placed into the three-year fixed ISA at 4.6 per cent would return £2,762.37 across the full term. Over five years, the five-year fixed ISA would generate £4,822.23 in interest.
Nationwide also confirmed changes to some of its flexible savings products. Its one-year Triple Access ISA pays 3.30 per cent AER tax-free, although the rate falls to 1.05 per cent after four or more withdrawals. The same terms apply to the building society’s one-year Single Access Saver, which also pays 3.30 per cent AER variable.
Nationwide Says Customers Continue to Value Branch Access
Richard Stocker, Head of Savings at Nationwide, said the organisation wanted to provide customers with a range of savings options across different terms. “We’re pleased to launch new higher rates across our Fixed rate ISA range with both short- and longer-term options,” he said.
Stocker also referred to Nationwide’s access options for customers who prefer branch banking. According to the building society, all ISA products and rates remain available in branch, online and by phone. “We know customers value choice in how they bank, which is why we’ve extended our Branch Promise,” Stocker said.
Nationwide added that customers can also use its in-app budgeting tool to manage their finances. The building society said older versions of the revised ISA products have now been withdrawn from sale for new account openings.
The mutual, which competes with banks including HSBC UK, Santander, Lloyds, NatWest and Barclays, has branches across the UK, including in Birmingham. Nationwide said further details about its savings range are available through its website and customer channels.
