What is the best NatWest Fixed Rate ISA?
A Fixed Rate ISA is a savings account where you put away money for a set period of time, usually 1-3 years. In return for locking away your money, you’ll receive a guaranteed interest rate for a fixed time period. Because it’s an ISA, your interest will also be tax-free, unlike funds saved in a normal savings account.
You can save up to £20,000 in ISA accounts across different providers each tax year. Tax treatment depends on individual circumstances and may be subject to change in the future
What is NatWest’s best fixed rate ISA?
NatWest’s current best Fixed Rate ISA is their 1-year Fixed Rate Cash ISA offering 4.0% AER (fixed). But there are other Fixed Rate ISAs offering higher rates than this that are currently on the market. If you’re looking for the top Fixed Rate ISA on the market, it is often worth looking beyond high street banks, as these don’t always offer the most competitive rates.
What are the current NatWest fixed rate ISAs?
NatWest currently offers two Fixed Rate ISAs; their 1-year Fixed Rate ISA and their 2-year Fixed Rate ISA. Once the fixed term has ended on either account, your account will automatically mature into NatWest Cash ISA, which offers a substantially lower interest rate of 1.50% AER (variable).
- 1 Year Fixed Rate ISA: 4.0% AER/tax-free (fixed). Requires a minimum opening deposit of £1,000, and after the pay-in window you can't add any more money to the account. As this is a fixed-rate account, you’ll be agreeing to lock away your money for a fixed period of 1 year. If you choose to withdraw your funds before this point, this will close the account and you’ll have to pay an early access charge equivalent to 90 days' interest.
- 2 Year Fixed Rate ISA: 3.75% AER/tax-free (fixed). Requires a minimum opening deposit of £1,000, and after the pay-in window you can't add any more money to the account.

How to find the best Fixed ISA Rates
Many familiar, high-street banks offer Fixed Rate ISAs. Opening an account with them may seem the easiest option, but they don’t always offer the best rates. To find the best Fixed Rate ISAs, compare accounts from different providers, including smaller ones you might not have heard of before. As well as the rate, look at if the provider ticks other boxes, like having excellent customer service, or an easy-to-use savings app with intuitive savings features to help you save more.
