What are the current Leeds Building Society Cash ISA rates?

Leeds Building Society currently has 13 Cash ISAs to choose from, with rates ranging from 1.45% AER (variable) to 4.40% (fixed). Some accounts are fixed-rate Cash ISAs, so you will agree for your money to be locked away for a set time period. Others are easy-access accounts but with much lower interest rates, or have minimum deposit requirements. However, while their rates are not the lowest on the market, they are not always the highest being offered, so it's always worth exploring other options.

What is Leeds Building Society’s best Cash ISA rate?

Leeds Building Society's best Cash ISA rate is currently 4.50% AER (fixed), which you can get by opening their 5 Year Fixed Rate Cash ISA or 5 Year Fixed Rate Monthly Income Cash ISA. Their 2 and 3 year fixed rate ISAs offer a slightly lower rate of 4.40% AER (fixed). With all of these accounts, the interest rate is fixed, meaning it won't change during the term - but you won't have penalty-free access to your money during this time.

Is Leeds a good Cash ISA provider?

Yes, Leeds Building Society is a solid ISA provider, especially if you're comfortable locking your money away for a fixed term. They offer a good mix of fixed-rate and variable-rate Cash ISAs, with options for easy access, limited access, and monthly income accounts. You can also transfer in existing ISAs from other providers, and open most accounts online, by post, or in-branch.

That said, their best rates are reserved for savers who'll lock their money away for a set period or keep at least £100 in their ISA at all times. And while their rates are competitive, Leeds Building Society is just one of hundreds of ISA providers. It's always a good idea to compare a few different options before committing, as you can usually get a better rate from a smaller provider.

Can I have two ISAs with Leeds Building Society?

You can only open and pay into one Leeds Building Society Cash ISA each tax year, but you could open a second Cash ISA with a different provider and pay into both during the same tax year. If you’ve got a Cash ISA already but you’ve found a better interest rate elsewhere, another option is to transfer your ISA to a new provider. This may make it easier to manage your tax-free savings, as everything will be in one place.

If you’re aged 18 to 39 and you’re saving a deposit for your first home, you could get the keys to your own place even sooner with the help of a Lifetime ISA (LISA). Save up to £4,000 of your total ISA allowance in a Lifetime ISA each year and the government will boost your savings with a 25% bonus, up to £1,000 each tax year. So, if you max out your LISA for 5 years in a row, you’ll have a £25,000 deposit towards your first home — even more if you choose a LISA with a competitive interest rate. 

Leeds Building Society doesn’t offer Lifetime ISAs, but we do! With the Tembo Cash Lifetime ISA, not only will you get the 25% government bonus, you’ll also benefit from our market-leading 4.00% AER interest rate (variable).

There are a few things you need to know before opening a LISA. For example, if you make a withdrawal for anything other than your first home or retirement, you’ll be hit by a 25% withdrawal penalty. This could leave you with less than you put in. Take a look at our guide to the Lifetime ISA withdrawal penalty to learn more about how this works.

Will Leeds increase ISA rates?

Leeds Building Society could increase its ISA rates, but it could lower them instead. There’s no way of knowing exactly what will happen to interest rates in future, but banks, building societies and other ISA providers tend to change their interest rates based on changes to the Bank of England’s base rate.

If you already have a fixed rate Cash ISA with Leeds Building Society, your interest rate will stay the same for the remainder of your fixed term, even if the building society does make changes to its ISA rates.

How to find the best Cash ISA Rates

There are dozens of Cash ISA providers to choose from and some of the best ISAs can be opened and managed via an app, rather than through a branch. The interest rate is important (especially during periods of high inflation), but it’s wise to compare other factors too, such as:

• Customer service quality
• How easily can you access your money
• Customer bonuses or rewards 

At Tembo, our award-winning savings app has helped thousands of savers over the last few years. It’s no wonder we’ve been rated Excellent on Trustpilot!

How to transfer my Leeds ISA to another provider

To transfer your Leeds Building Society ISA, simply open a Cash ISA with your chosen provider and ask them to complete the switch for you. Whatever you do, don’t try to make the transfer yourself, as this can impact your savings’ tax-free status and this year’s ISA allowance! 

For example, let’s imagine you’ve saved £20,000 in a Cash ISA over a number of years and you’d like to transfer your savings to a new provider. Try to move the money yourself and you’ll use up your full £20,000 ISA allowance for this tax year, even though your contributions were originally made during previous tax years. You’ll need to wait until the following tax year to make any more ISA contributions. Until then, you’ll need to keep your cash in a traditional savings account, where your savings interest will be taxable.
