What are the current Nationwide ISA rates?

Nationwide currently offers five types of Cash ISA products, the best ones offering a 4.60% AER interest rate (fixed) for agreeing to lock away your money for a set time period of five or three years. After this, you will be automatically moved onto an instant access Cash ISA, which pays a lower rate of interest.

It's worth noting that Nationwide's Fixed Rate Cash ISAs are designed for saving a one-off lump sum rather than regular saving - unlike the Tembo Fixed Rate Cash ISA. You can only deposit money when you first open the account. After the fixed term ends, your money will be automatically moved onto an instant access Cash ISA, which pays a lower rate of interest.

For all four Fixed Rate Cash ISAs, withdrawing your money before the end of your fixed term will close the account and trigger an early access charge. If the charge is more than the interest you've earned, you could get back less than you paid in. So it's important to be sure you won't need access to your funds during the fixed period.

What is Nationwide’s best ISA rate?

Nationwide's current best Cash ISA rate is 4.60% AER (fixed), which you can access by opening its 5-Year or 3-Year Fixed Rate Cash ISAs. To put that into perspective, a £1,000 lump-sum deposit at 4.60% AER would grow to around £1,144.45 after 3 years or £1,252.16 after 5 years. Although this is a competitive interest rate for a Cash ISA account, there are other Cash ISAs on the market which pay a higher interest rate than this, without having to lock your money away for as long.

Is Nationwide a good Cash ISA provider?

Nationwide offers a small selection of ISA savings accounts, all of which have competitive interest rates. However, for their top rates, you have to be happy to lock away your money for a set time period. After this, you'll be automatically moved onto Nationwide’s instant Cash ISA with a much lower interest rate. If you're new to Nationwide, you'll need to apply in person at a branch, which may be less convenient than opening an account online with another provider. There are other Cash ISAs available on the market that offer similar or better interest rates, without the same time restrictions. Plus, both Nationwide’s Cash ISAs have withdrawal limitations. 

Can I have two ISAs with Nationwide?

Yes, you can have more than one ISA with Nationwide, but you can only pay into one Nationwide Cash ISA each tax year. You can open multiple ISAs in the same tax year with different providers, as long as you don’t exceed your annual ISA allowance of £20,000. So, for example, you could also hold a Cash ISA, Lifetime ISA or Stocks and Shares ISA with a different provider.

Will Nationwide increase ISA rates?

Nationwide might increase its ISA rates, but it also could lower them. It depends on what is happening with the wider market and live interest rates. For example, in March 2026, Nationwide increased rates on its Fixed Rate Cash ISAs ahead of the new tax year as competition between providers ramped up. If other banks and building societies start lowering or raising their Cash ISA rates, Nationwide could follow suit.

If you already have a Nationwide Fixed Rate Cash ISA, your interest rate will stay the same for the remainder of your fixed term, even if Nationwide's ISA rates change.

How to find the best Cash ISA rates

The best way to find the top Cash ISA rates is to compare offerings across different providers, not just the bank you already bank with. Opening a Cash ISA with the same bank you have a current account with, particularly if you’ve banked with that particular provider for a long time, may seem like the most straightforward option. In fact, 52% of people with a Cash ISA use the same provider for their tax-free savings as they do for their current account. However, you could be missing out on a better interest rate elsewhere. Compare different ISA providers, including smaller banks which might not be on the high street, to decide on the right account for you.

When comparing Cash ISAs, think about:

• The interest rate (AER) and whether it's fixed or variable
• How easily you can access your money, some accounts limit withdrawals or charge penalties
• Whether you want to save a lump sum or make regular deposits
• Whether you can open and manage the account online

Don't overlook smaller banks and building societies that might not be on the high street — they often offer some of the most competitive rates. For more information, take a look at our guide on the Best Cash ISAs in the UK.

How to transfer my Nationwide Cash ISA to another provider

To transfer your Nationwide ISA to another provider, all you need to do is open the new Cash ISA and request a transfer. Moving the money over to yourself could have an impact on your savings’ tax-free status. 

Moving money manually can impact your tax-free status. For example, if you move £25,000 yourself:

• You use up your full £20,000 annual ISA allowance immediately.
• The remaining £5,000 must stay in a standard savings account.
• You may pay income tax on the interest earned by that £5,000.

By using the official transfer service, you protect your tax-free status and preserve your current year's allowance.

Calculations show at month 61 (after 5-years) Tembo customers saving at 4.05% AER (variable) for the first 12 months, then 2.8% AER (variable) after that would have £242.49 on average more than saving with Barclays, HSBC, NatWest or Lloyds.
