Nationwide Building Society has launched a new Cash ISA offering 4% interest while also increasing returns across four existing ISA accounts. The changes came into effect yesterday (March 6), with the company introducing two new products designed to give savers competitive tax-free returns.
The new accounts include a 1 Year Single Access ISA paying 4.00% and a 1 Year Single Access Saver also offering 4.00% interest. At the same time, Nationwide has boosted rates across its Fixed Rate Cash ISA range, with improved returns available for customers willing to lock their savings away. Richard Stocker, head of savings, said: “We’re pleased to be increasing rates across our ISAs and our instant access savings product, giving members even more long‑term value and meaningful benefits.

“Combined with our Branch Promise, we’re proud to be bringing even more value to the high street, further demonstrating our commitment to offering positive, competitive rates for our members.”
The two new accounts will offer members 4% returns on both their 1 Year Single Access ISA and their 1 Year Single Access Saver.
Additionally, Nationwide will increase rates on its 1, 2, 3 and 5 Year Fixed Rate Cash ISAs.
The five year fixed rate will see returns of 4.25% while the remainder will provide 4.05%.
At the same time, the Society will withdraw its existing 1 Year Triple Access ISA and 1 Year Triple Access Saver, both currently offering 3.30%.

Caitlyn Eastell, personal finance analyst at Moneyfactscompare.co.uk, said: “With the new tax year fast approaching, ISA season is coming into full swing. Typically, this is when providers will compete most fiercely to make their deals enticing to new customers. This year is gearing up to be particularly competitive as the 2026/27 tax year marks the final year for those under 65 to utilise their full £20,000 cash ISA limit.”
Commenting on Nationwide’s new deals, Ms Eastell said: “Nationwide Building Society’s latest hikes to their fixed rate cash ISAs are enough to push a handful of them into the top rate tables, with the five-year option now paying a market-leading 4.25%.
“Fixed-rate accounts may be a popular option among savers to protect their returns for longer. While short-term base rate expectations are volatile, markets are widely predicting interest rates to fall in the longer term, which can drag savings rates down with it.
“However, while its access ISA offers inflation-busting 4.00% headline rate, savers are very limited with the number of withdrawals that can be made.
“Many of the market-leading easy-access accounts allow unlimited access, and they currently pay around 4.50%. This means savers depositing the full £20,000 allowance could be about £100 better off over a year. But it’s important that savers take note of any introductory bonuses and when they expire, otherwise they could see their returns diminish rapidly.”
