What are the current Coventry Building Society Cash ISA rates?

Research shows that 52% of people with a Cash ISA use the same provider they use for their current account, but this isn’t always a good idea! The big high-street banks don’t necessarily offer the most competitive rates. To see how another provider could help you reach your savings goals faster, take a look at our guide to the Best Cash ISAs in the UK.

What are the current Coventry Building Society ISA rates?

Coventry Building Society currently offers five Cash ISA saving products, with the most competitive rates available for under 18s or adults willing to lock their cash savings away for a set time period. Their rates range from 2.65% (variable) AER with their Easy Access ISA to 4.50% (variable) AER with their Junior Cash ISA. 

• Junior Cash ISA: 4.50% (variable) AER/tax-free. You (or your child) can open this Cash ISA with as little as £1 and up to £9,000, but they won’t have access to the money until the child has reached 18 years of age. Interest is calculated daily, but is paid annually, and one final interest payment will be made on the child’s 18th birthday.
• Fixed Rate ISA: 3.90% (fixed) AER/tax-free until 30th November 2026. As this is a fixed-rate Cash ISA, if you withdraw money from the account during the fixed rate period the account will be closed and you'll be charged the equivalent to 180 days’ interest on the account balance. Interest is calculated daily, but paid annually or monthly at the end of the last day of each month. Annual interest can be added to the ISA account or paid into another account. Monthly interest must be paid into another account.
• Easy Access ISA (Online) (5): 2.95% (variable) AER/tax-free. You can open this Cash ISA with as little as £1, and you’ll have easy access to your money with no penalties for withdrawals, but you’ll only have access to Coventry’s online services. Interest is calculated daily, but is paid annually or monthly on the last day of each month.
• Additional Allowance ISA: 2.70% (variable) AER/tax-free. This is an ISA for people who have inherited an extra ISA allowance from a spouse or civil partner. You must have been living with your spouse or civil partner at the time of their death, are a UK resident and are over 18 years old. The amount you can save in an Additional Allowance ISA depends on the date your partner passed away and the amount of ISA savings they held with Coventry Building Society. As this is an easy access ISA, once set up you’ll get instant access withdrawals with no penalties. Interest is calculated daily, and is paid annually.
• Easy Access ISA: 2.65% (variable) AER/tax-free. You can open this Cash ISA with as little as £1, and you’ll have easy access to your money with no withdrawal penalties. ‍Interest is calculated daily, but is paid annually or monthly on the last day of each month.

Is Coventry Building Society a good ISA provider?

Coventry Building Society does have some competitive interest rates, but its best Cash ISA rates are reserved for junior savers or those who are willing to lock away their money for a set time period. If you want an easy-access account, Coventry Building Society might not be the best option as you may get better interest rates with a different provider. 

Not only that, other providers may offer better customer service too. Here at Tembo, for example, we’ve helped thousands of people save for the future and even get on the property ladder with our award-winning savings app. We’re also rated Excellent on Trustpilot, so you can be sure that we’re the real deal!

Can I have two ISAs with Coventry Building Society?

You can open and pay into multiple Cash ISAs in the same tax year, but only one of them can be with Coventry Building Society. If you’ve already got a Cash ISA with Coventry or another provider and you’re looking for a more competitive rate, it’s up to you whether you keep multiple accounts or transfer your current ISA to a new provider.

If you’re saving a deposit for your first home, it may make sense to have a Cash ISA and a Lifetime ISA (LISA). Save up to £4,000 of your total ISA allowance in a Lifetime ISA each year and you’ll get a 25% bonus from the government - up to £1,000 each tax year! This means that if you max out your LISA for 3 years in a row, you’ll have a £15,000 deposit towards your first home. Choose a LISA with a competitive interest rate and you’ll have even more than this!

Buying a house with another first-time buyer? You can have a LISA each, potentially giving you double the savings, double the bonuses, and even more interest!

Take a look at our guide to the Lifetime ISA withdrawal penalty for more information.

Will Coventry Building Society increase ISA rates?

Coventry Building Society could increase its ISA rates, but it could lower them instead. Banks and building societies tend to use the Bank of England’s base rate as a guide when setting their own rates. If the base rate rises, banks and building societies often increase their mortgage and savings rates too. If the base rate falls, mortgage and savings rates often follow. But it’s impossible to know exactly what will happen to interest rates in future.

If you already have a fixed rate Cash ISA with Coventry Building Society, your interest rate will stay the same for the remainder of your fixed term, even if the Bank of England’s base rate drops or your provider changes its current ISA offering.

How to find the best Cash ISA Rates

With so many providers to choose from, don’t just compare interest rates. Compare customer service quality, how easy it is to access your money and whether the provider offers bonuses or rewards too! The right Cash ISA can make a huge difference to your savings progress in both the short and long term.  For example, by saving with a Tembo Cash ISA, over 5 years you'll earn hundreds more in interest than if you were to save in a similar account with one of the four biggest banks!

How to transfer my Coventry ISA to another provider

Transfer your Coventry Building Society ISA to another provider by simply opening a new ISA and asking your new provider to move the money for you. Don’t try to complete the switch yourself, as this can impact your savings’ tax-free status and this year’s ISA allowance! 

Let’s imagine you’ve saved £35,000 in a Cash ISA over a number of years and you’d like to transfer your savings. If you try to move the money yourself, this could use up your full £20,000 ISA allowance for this tax year. You’ll also have to wait until the following tax year to move the remaining £15,000 into your new Cash ISA. Until then, you’d need to keep the money in a traditional savings account, where your interest would be taxed.
