Cash ISAs are a fantastic way to save money for a short term period and earn a consistent interest rate on your balance.
What should you consider when choosing a cash ISA?
Consider what you value most before you choose a cash ISA product to save into. Here are some of the most important considerations when choosing a savings product:
Cash ISAs can be the perfect option if:
- you want a guaranteed rate of return on your savings
- you need access to your money (although some accounts are “fixed” or limit withdrawals)
- you have a savings balance of up to £20,000 to save
- you haven’t yet used your £20,000 ISA allowance this financial year (2024 – 25 financial year 06th April 2024 – 05th April 2025).
You may prefer an alternative product type, like an investment account or stocks and shares ISA if:
- you’re willing to risk short to medium term losses for longer term growth
- you’re unlikely to need the money soon
- you’ve already used your ISA allowance but have more money to save or invest (a general investment account could work here)
- you’re looking for greater returns than cash ISAs can offer
- you’ve already paid your entire £20,000 allowance into either a cash ISA or a stocks and shares ISA this financial year.
It isn’t just about getting the best cash ISA savings rate but also about:
- access to withdraw your money when you need to
- how you can use, pay into, withdraw from and manage your account (online has largely replaced in-branch account options).
- beating the rate of inflation (if you can) because inflation erodes the value of your money if you’re saving at or below this rate you’re technically losing money
- the base rate of interest, if you have a tracker mortgage or are borrowing money, you may be better off putting the money towards paying down your debts.
Cash ISAs Compared
Generally, cash ISA savings products are designed to help you earn interest on the money you deposit while offering access to the money you have saved when you need it.
Cash ISAs that allow unrestricted access to your money are called easy access or instant access ISAs.
Other types of cash ISA can reward you, often with higher interest rates (and therefore better returns on the balance you deposit, but not always!), when you agree to lock your money away for fixed period of time.
These types of ISAs are called fixed rate cash ISAs.
Popular terms available for fixed rate cash ISAs include:
| Term | Interest Rate | Number of Years |
|---|---|---|
| 1 year | 4.30% | Money locked away for 1 year |
| 2 years | 4.55% | Money locked away for 2 years |
| 3 years | 4.75% | Money locked away for 3 years |
| 5 years | 5.00% | Money locked away for 5 years |
For example, if you’re solely interested in earning the best interest rate and don’t need the money for at least 12 months, you can factor in fixed rate cash ISA savings into your comparison.
Sometimes, the rate of return you’ll get for locking money away can be higher if you agree to a longer term of no or restricted access to your deposit.
Our table, for example purposes only, details how a provider might incentivise longer fixed term cash ISA deposits with higher rates for longer terms.
If you may need the money soon, then choosing an account which doesn’t limit your withdrawals and doesn’t issue interest penalties for making a withdrawal would best suit you.
How to use our Cash ISA comparison table
We’ve picked some of the best ISA providers who offer Cash ISA savings options and consolidated details of their products into our table.
We’ve included essential details like:
- the interest rate you can earn on your money
- the current rate of inflation (which is the rate at which your savings are eroded by continually rising prices)
- the Bank of England base rate of interest (which can affect the cost of borrowing, like your mortgage or loans)
- Security, FCA (Financial Conduct Authority) and FSCS (Financial Services Compensation Scheme) regulation and protections
- Minimum account deposits, withdrawal limits, access types and any other information
The Best ISA Rate?
Right now, the best cash ISA rate isn’t a fixed account, but an easy access account provided by the fintech provider plum.
The account offers an interest rate of 5.18% on balances you deposit, accepts transfers of existing ISAs in but the account limits your withdrawals to up to 3 over a 12 month period.
The rate is made up of a 3.79% base interest rate, with a bonus 1.39% added to your interest rate for the first 12 months of opening your account.
Be warned, the rate won’t last beyond 12 months and is available to new customers only. Also, the rate will drop to just 2.50% if you withdraw more than 3 times from the account or your savings balance drops below £100.
Another consideration before choosing Plum for your cash ISA, is the shared FSCS protections the account has. If you hold savings or current accounts with Lloyds Bank or Citibank, the £85,000 FSCS protection offered by Plum may be split across all three accounts, so in the event of these banks failing you could lose money.
You can open the account within a few minutes using the plum app.
