Compare current cash ISA rates

You can have more than one ISA open at the same time. Mixing and matching could help you work towards different goals.

You can now open and fund multiple ISAs of the same type, in the same tax year, with different providers.

You can open and subscribe to one Cash ISA (instant access or fixed rate) with us per tax year.

If you have opened a Cash ISA with another provider/s you can still open a Cash ISA with us.  You are responsible for ensuring you do not exceed the current yearly subscription limit of £20,000 across all ISAs.

Once your 1 year or 2 year Fixed Rate ISA ends, we’ll automatically change your account into an instant access Cash ISA. You’ll then have a few options. We’re here to explain your choices so that you can make the best decision, based on your savings goals.

You can use mobile banking, online banking, direct banking or any branch to pay funds into your Cash ISA.

If you've got more than one type of ISA, just make sure you're not paying in more than your ISA allowance of £20,000 for the current tax year across all your ISAs. Tax years run from 6th April to 5th April the following year.

Additionally, you can choose whether you want to pay in lump sums, or set up a monthly standing order to help you save more regularly.

There are four different types of ISAs to choose from, but not all providers will offer all of them. At NatWest, we offer Cash ISAs and Stocks & Shares ISAs.

• Cash ISA: These are simple, tax-free savings accounts. Some Cash ISAs give you instant access to your money and are a flexible way to save and plan short-term. Fixed Rate ISAs give you a guaranteed interest rate for one or two years.
• Stocks & Shares ISA: A tax-efficient investment account that could include shares, bonds or funds. Any investment gains or income should be tax-free and you could access a variety of investments. These ISAs are meant to be a medium to long-term investment, meaning they should be held for at least five years.
• Innovative Finance ISA: This type of ISA lets you put money into peer-to-peer lending.
• Lifetime ISA: These can help you to save or invest for a first home or later life.  Find out more.

An ISA is a form of savings account. The main difference between an ISA and a traditional savings account is that an ISA offers tax-free savings up to £20,000 in the current tax year (6 April 2024 to 5 April 2025).

A traditional savings account will only offer up to £1,000 tax free, depending on your income tax personal savings allowance.

ISA accounts and their tax-free benefits are designed for one person. This means you won’t be able to share an ISA account or transfer it to another person.

But there are other options available. For example, our joint Flexible Saver is a great way for two people to save money together and earn interest.

Help to Buy ISAs offer a 25% government bonus for first-time buyers saving for a house deposit. Currently, these are not available to new applicants.

Help to Buy ISAs are not available to new applicants as of 1st December 2019.

Your PSA is separate from your ISA allowance.  The amount of allowance will depend on the type of tax payer you are. The interest you earn from an ISA will not impact your personal savings allowance.

• Basic rate tax payers at 20% can earn £1,000 in savings interest per year with no tax.
• Higher rate tax payers at 40% can earn £500 in savings interest per year with no tax.
• Additional rate tax payers at 45% do not get any allowance. 

How long will it take for my ISA transfer from a non NatWest provider?

• Cash ISA's – please allow up to 14 days, although it may take a little longer dependent on your provider.
• Stocks & Shares ISA - please allow up to 30 days.
• From an internal transfer – up to 5 working days.
• If your current provider uses the manual transferring process, this could take a longer time as we are relying on them sending both your transaction history list and your balance.

I am a new customer - How do I verify my identity to progress my application?

• Once you've completed your application and provided a valid mobile number and email address, you'll receive an invite from our security partner Mitek, to upload any ID we need. We'll send your invite by text and email.
• Customers who don't hold a UK or EU/EEA photo ID will be sent a paper pack in the post instead of a text and email. This will arrive within 3-5 working days.

How can I find details of my interest rate / info sheet / issue number / funding dates for my Fixed Rate ISA?

• Fixed Rate ISA information sheets can be found by clicking here. This will include your issue number, interest rates and the dates for funding. You can also view your interest rate in the mobile app by clicking view my account and view interest rate.
