Nationwide Building Society overhauls savings accounts with 'longer-term value' interest rates - full list

Richard Stocker, the 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."

These changes from Nationwide will take effect today, March 6, and come a month before the cut-off for Britons to take advantage of their tax-free ISA allowance.

As it stands, savers can deposit up to £20,000 into either cash or stocks and shares ISAs, with their savings being protected from a potential tax raid from HM Revenue and Customs (HMRC).

Under reforms from Chancellor Rachel Reeves, this tax-free allowance attached to cash ISAs is being reduced to £12,000 from April 2027.

The deadline for Britons looking to make the most of their tax-free allowance is April 6 every month

Here is a full list of the new Nationwide Building Society accounts:

• 1 Year Single Access ISA – four per cent.
• 1 Year Single Access Saver – four per cent.

• 1 Year Fixed Rate ISA – 4.05 per cent
• 2 Year Fixed Rate ISA – 4.05 per cent
• 3 Year Fixed Rate ISA – 4.05 per cent
• 5 Year Fixed Rate ISA – 4.25 per cent.

Caitlyn Eastell, a 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 because the 2026-27 tax year marks the final year for those under 65 to utilise their full £20,000 cash Isa limit.

"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 per cent.

"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 longer term, which can drag savings rates down with it.

"However, while its access ISAs offer an inflation-busting four per cent headline rate, savers are very limited with the number of withdrawals that can be made. Many of market-leading easy access (deals) allow unlimited access, and they currently pay around 4.50 per cent."
