Nationwide Building Society has announced a significant rule change affecting six groups of customers, with new cash ISA rates taking effect from Wednesday, 6 May 2026. The mutual, which operates branches in Birmingham and across the UK, is withdrawing older versions of its cash ISAs and introducing new editions with updated interest rates.
New Cash ISA Rates Announced
In a statement released on its website, Nationwide confirmed the launch of an array of new fixed and variable savings products. The new rates include:
- 1 Year Fixed Rate Cash ISA – 4.50% AER/Tax-free (fixed)
- 2 Year Fixed Rate Cash ISA – 4.55% AER/Tax-free (fixed)
- 3 Year Fixed Rate Cash ISA – 4.60% AER/Tax-free (fixed)
- 5 Year Fixed Rate Cash ISA – 4.60% AER/Tax-free (fixed)
- 1 Year Triple Access ISA – 3.30% AER/Tax-free (variable) (1.05% after 4 or more withdrawals)
- 1 Year Single Access Saver – 3.30% AER/Gross a year (variable) (1.05% after 4 or more withdrawals)
These products are designed to cater to different customer needs, from those seeking fixed returns over short to medium terms to those requiring more flexibility with variable rates.
Statement from Nationwide's Head of Savings
Richard Stocker, Head of Savings at Nationwide, commented: “We’re pleased to launch new higher rates across our Fixed rate ISA range with both short- and longer-term options. For those who require 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, which is why we’ve extended our Branch Promise. Customers can also make use of our in app budgeting tool to help them manage their money.”
Impact on Existing Accounts
The shake-up means that older versions of these products will no longer be available for new account openings from 6 May 2026 onwards. Nationwide, which competes with major banks such as Santander, HSBC UK, NatWest, Lloyds Bank, and Barclays, is expected to see strong demand for the new rates.
Customers are advised to check their current ISA holdings and consider switching to the new products to benefit from the improved rates. The changes come as part of Nationwide's ongoing commitment to providing competitive savings options and enhancing customer choice.
