If you’re on the hunt for the best Cash ISA for your savings, keep in mind that the big high-street banks don’t always offer the most competitive rates - take a look at our guide on the Best Cash ISAs in the UK for more information.

What are the current Halifax ISA rates?

Halifax offers a variety of Cash ISA products, from fixed Cash ISAs to bonus saving accounts which reward fewer withdrawals with higher rates - these range from 0.75% AER (variable) to 4.20% AER (fixed), depending on the account type you choose and if you have a Halifax Personal Current Account. However, there are ISA accounts on the market which offer substantially higher rates than this.

What is Halifax’s best ISA rate?

Halifax’s best Cash ISA rate is currently 4.20% AER (fixed) on its 2-Year or 5-Year ISA Saver Fixed account. If you want an account you can withdraw from, the best ISA rate from Halifax's range is its ISA Reward Bonus Saver, which offers an interest rate of 2.75% AER (variable).

Again, this isn't the most competitive interest rate offered on a Cash ISA. Plus, if you make four or more withdrawals from this account, you'll get a much lower rate of interest at 0.65% AER (variable).

Is Halifax a good ISA?

Halifax offers a good range of easy-access ISA savings accounts as well as fixed-rate ISAs, offering a range of interest rates, withdrawal limits and minimum balance requirements. However, like most high-street banks, Halifax does not offer the most competitive interest rates across a lot of its Cash ISA accounts, some offering as low as 0.75% AER (variable). There are some Halifax ISA accounts that offer better interest rates, but they are only available for between 1-5 years and have withdrawal limits. They also don't offer the most competitive rates for Fixed Rate ISAs. After this set term period, you’ll be automatically moved onto their Instant ISA Saver, which has a much lower interest rate.

Can I have two ISAs with Halifax?

Yes, you can have two ISAs with Halifax, but you can only pay into one Halifax Cash ISA each tax year. However, you can open and contribute to a Cash ISA with another provider. If you’ve already contributed to a Halifax Cash ISA this year but you’ve found a better option elsewhere, you can open a second account or transfer your existing ISA to the new provider. You can also save into a Lifetime ISA or Stocks and Shares ISA with a different provider during the same tax year - just remember that the annual ISA allowance of £20,000 applies across all your ISA accounts, regardless of the number of ISAs you hold.

Will Halifax increase ISA rates?

Halifax may increase the interest rates on its ISA savings accounts, but it also could lower them - it all depends on what’s going on in the wider market. If interest rates across the market start going down, chances are Halifax will reprice its savings accounts to reflect current rates. If you open a fixed-rate Cash ISA, the interest rate will remain constant throughout the fixed term, even if Halifax changes its advertised rates. After the fixed term ends, you can either open a new Halifax Cash ISA or transfer your savings to another provider. 

If you're saving for a house deposit, you could transfer up to £4,000 of your Cash ISA savings into a Lifetime ISA (LISA). Your LISA savings will be topped up by a 25% bonus from the government and you can use the money within your account to buy a home worth up to £450,000.  

How to find the best Cash ISA Rates

Opening a Cash ISA with your current bank might seem like the easiest option, but this could mean missing out on more competitive rates elsewhere. By comparing a few ISA providers and different types of accounts before making a decision, you can make sure your Cash ISA is right for you!

When comparing providers, you want to look at more than just their interest rates. It’s also worth looking for good customer service. Check their reviews (We’re rated Excellent on Trustpilot!) and how easy it’ll be to access your funds and whether there are any bonus features or benefits. 

A fixed Cash ISA will usually offer the most competitive rates, but you’ll need to lock your money away for a set period of time. If you want to be able to withdraw your money without any penalties, consider an easy-access Cash ISA. A notice account could give you the best of both worlds, but you’ll usually need to give between 30-90 days’ notice to access your cash, depending on the provider and terms. 

How to transfer my Halifax ISA to another provider

To transfer your Halifax ISA to another provider, simply open a new ISA with the new provider and ask them to handle the transfer. Moving the money yourself could have an impact on your savings’ tax-free status and affect your current year’s ISA allowance.

For example, if you’ve saved £32,000 in a Cash ISA over several years and you wish to transfer to a new provider, doing it yourself would use up your entire £20,000 ISA allowance for the year. You’d need to place the remaining £12,000 in a traditional savings account, where any interest you earn would be taxed.

By having your new provider manage the transfer, you can protect your savings’ tax-free status and your ISA allowance for the current tax year.
