What is the best Halifax Fixed Rate ISA?

By

Last Updated 16 May 2025

A Fixed Rate ISA lets you earn a guaranteed interest rate on your savings for a set period of time. You won’t be able to access your savings until the end of your fixed term, but your interest rate will be protected from fluctuations during this period. And, since it’s an ISA, all your interest will be tax-free, making it easier and faster to grow your savings.

In this guide, we’ll cover all the Fixed Rate ISAs currently offered by Halifax. If you’re looking for the best Fixed Rate ISA available across providers, keep in mind that the familiar high-street banks don’t always offer the most competitive rates.

Withdrawing funds before maturity will incur a charge. Partial withdrawals from some Fixed Rate ISAs are restricted. Tax treatment depends on individual circumstances and may be subject to change in the future

What are the current Halifax Fixed Rate ISAs?

Halifax has one type of Fixed Rate ISA, their ISA Saver Fixed, with a choice of three different term lengths. You can choose to lock away your savings for between one, two or five years, after which the account will change to an Instant ISA Saver. Please note, Halifax only lets you save into one Cash ISA with them each tax year; so if you’ve already put money into another Halifax Cash ISA, you’ll have to wait until the next tax year to open this account, or choose another provider. 

  • 1-Year ISA Saver Fixed: 4.00% AER (fixed). The minimum deposit is £500, and you can add as much as you like to the account within the first 60 days (as long as it's within your annual ISA allowance). After the end of the term, your account will automatically mature into their with a variable (and much lower) interest rate. You can’t withdraw money without closing the account early or transferring your money to another ISA. If you do either of these options before the fixed term ends, you would be charged the same as 90 days’ worth of interest.
  • 2-Year ISA Saver Fixed: 3.85% (fixed). The minimum deposit is £500, and you can add as much as you like to the account within the first 60 days (as long as it's within your annual ISA allowance). After the end of the term, your account will automatically mature into their with a variable (and much lower) interest rate. You can’t withdraw money without closing the account early or transferring your money to another ISA. If you do either of these options before the fixed term ends, you would be charged the same as 180 days’ worth of interest.
  • 5-Year ISA Saver Fixed: 3.70% (fixed). The minimum deposit is £500, and you can add as much as you like to the account within the first 60 days (as long as it's within your annual ISA allowance). After the end of the term, your account will automatically mature into their with a variable (and much lower) interest rate. You can’t withdraw money without closing the account early or transferring your money to another ISA. If you do either of these options before the fixed term ends, you would be charged the same as 365 days’ worth of interest.

Can I withdraw money from a Halifax Fixed Rate ISA?

You can only withdraw money from a Halifax ISA Saver Fixed at the end of your fixed term. If you want to access your money before that, you’ll need to close your account, or transfer to another ISA; in both situations you’d pay a charge. If you have a 1-year term, you’ll be charged a fee equal to 90 days’ tax-free interest. If you have a 2-year term, you’ll be charged a fee equal to 180 days’ tax-free interest. If you have a 5-year term, you’ll be charged a fee equal to 365 days’ tax-free interest. So it makes sense to find the right Fixed Rate ISA for you before making a commitment! 

Can I transfer money into a Halifax Fixed Rate ISA?

Yes, you can transfer money into a Halifax Fixed Rate ISA, but it’s a good idea to compare a few providers online before requesting an ISA transfer. If you’re going to commit to a one, two or five-year term, you may as well choose an ISA with the best rate on the market!

How to find the best Fixed ISA Rates

There are plenty of Fixed Rate ISAs to choose from, with high-street banks and app-based providers you might not have heard of before. Opening an ISA with the bank you already hold a current or savings account with might seem like the easiest option, but this could see you missing out on a higher interest rate and better customer service elsewhere. 

Before making a decision, compare a few accounts from a handful of providers. This won’t take long, especially if you take a look at our guide to the best Cash ISAs in the UK right now

Wondering what to look for? The interest rate is important, but you’ll probably want good customer service, intuitive savings features and maybe even an app too. Once you’ve found the right Fixed Rate ISA provider, you can usually open an account and make a deposit in minutes.
