T212’s £1 minimum deposit makes it a good match for those starting small. One thing to note, however, the bonus rate only applies to current tax year contributions and new customers.
A very competitive rate that doesn't come with any penalties or limits on withdrawals.
Start with as little as £1 - and as they accept transfers, you can also get this rate on larger ISA pots that you've been saving into for many years too.
A flexible ISA is a type of Individual Savings Account that lets you withdraw money and pay it back in the same tax year without reducing your annual ISA allowance. This means if you put £20,000 in and take £5,000 out, you can put the £5,000 back in within the same tax year, without being 'over' your annual allowance.

4.12% AER (variable) including a bonus of 1.01% AER (variable) for 12 months on Plum Cash LISA
4.66% AER (variable) if account kept for 12 months on Plum Cash ISA
Capital at risk.
This is a strong rate if you’re a new customer and can therefore get the bonus rate. It’ll only last for 12 months, but there’s nothing to stop you shopping around for new rates after 12 months – in fact, keeping an eye on new offers is a necessity these days. One thing to note about this account is that you must stay put for the full 12 months to receive the 2.12% AER rate boost. And that is a variable rate, too, so could change.
If you’re transferring cash in, then the rate isn’t quite as high: 4.07% AER (variable), so paying in new cash (up to £20,000) is the way to get the most from this provider.
Helps you set sensible savings goals - and automate them to make them easier to achieve.
You can open a Plum Cash ISA with as little as £1.
Although the rate you'll receive on transferred funds is just 2.54% AER (variable).

eToro’s Cash ISA is not actually administered by eToro, but (like their Stocks and Shares ISA), comes via Moneyfarm who often pay strong rates of interest.
It’s a very strong rate, but it’s a variable rate, so can be lowered (or raised) throughout the year if the Bank of England base rate (or other factors) change. And as it’s a boosted rate, it’ll drop to 3.49% after 12 months.
You’ll need at least £500 in the account at all times, or – if you’re transferring in an existing ISA – a minimum of £15,000. And one other thing to be aware of, Moneyfarm invests your savings into

It’s not possible to transfer existing ISAs into this account, so the people who’ll get the most from this impressive interest rate will be those with their full annual allowance yet to invest.

You get unlimited penalty-free withdrawals with Lightyear’s great Cash ISA within the same tax year. It’s a really simple one to get to grips with interest-wise too, as it replicates whatever the Bank of England’s Base rate is. That means if the Bank of England raises rates, your interest rate will rise (although on the flip side, if they lower rates, your interest rate will also decrease).
Your interest is paid monthly, so you’ll be rewarded regularly instead of needing to wait for a year.
There are no limits. You can withdraw whenever you want in the same tax year and face no penalties whatsoever.
A flexible ISA is one that allows you to withdraw and repay money into your ISA without it affecting your annual allowance within the same tax year. For example, if withdraw £5,000 in June for a house deposit, then repay that £5,000 in November, it won't count twice towards your annual limit.
Keep all your ISA holdings under one - very low-cost - roof. Zero account and trading fees on Stocks & Shares ISA. (Fund manager and FX fees may apply.)

This Moneybox rate is exceptionally good. To keep the full rate, however, you are limited to a maximum of three withdrawals within each 12 month period, and you’ll need to maintain a balance of £500 or more. If you don’t stick to those rules, the rate drops to a paltry 0.75% AER (variable).
The headline rate also includes a bonus of 0.94% AER, which will be removed after the first 12 months and is variable, so it can be raised or dropped if Moneybox so chooses. There’s nothing tying you to the account though if that happens.
If you want unlimited withdrawals, you can still benefit from a really strong rate of interest with Moneybox: 4.00% AER (variable), including a 0.85% promotional boost for the first 12 months
1.5 million people save with Moneybox.
Moneybox customers value the easy-to-use app and smart saving features such as 'round-ups' and regular, automated saving.

This is a strong rate from a high street name, you’ll get the certainty of a guaranteed growth for 12 months (no matter what the Bank of England does to rates), and unlike with many other banks, you don’t need to open a current account with Tesco to get access to their ISAs.
The downside to a fixed rate is that if you need access to your money, you’ll need to close your account or transfer it to another provider. And to do that, you’ll incur a charge equivalent to 90 days’ interest, which will be deducted from your account balance.
A guaranteed rate for 12 months so you can work out in advance how much your money with grow.

Hargreaves Lansdown (HL) has, for some time, offered customers the ability to save into cash ISAs offered by other banks through the HL platform. But this Cash ISA, launched at the end of 2025, is the first directly-branded HL Cash ISA they’ve offered.
It’s been launched in partnership with Shawbrook which means Hargreaves Lansdown sets the interest rate while Shawbrook holds your money.
The current rate is particularly strong and it’s an easy access account. This isn’t a flexible ISA, however, which means that any money you withdraw loses its ISA status, and if you want to put it back you would have to use part of your annual ISA allowance again.
Withdraw your money whenever you like without incurring a penalty.
Unlike some other savings accounts which keep limits on how much you can save fairly low, HL allows transfers and deposits up to £1 million.

Read full reviewA cash ISA is a savings account but unlike regular savings accounts, any interest you earn is free of any tax. If you are already using up your personal allowance, then saving into a cash ISA will allow you to keep more of your gains.
You can save up to £20,000 into a cash ISA each tax year, anything over and above that amount will be subject to tax at your regular rate.
The personal savings allowance refers to the amount of money you can earn from interest without having to pay tax on those earnings. Remember, that within a cash ISA, this isn’t an issue as your earnings are protected from the taxman. However, when using regular savings accounts, anything over the personal allowance is subject to tax. The personal savings allowance is as follows:
They are the same! All the rules and regulations surrounding the product remain the same regardless of who the provider is. The main difference between the platforms I have recommended in this article, and the high street banks, is that the cash ISAs here offer better interest rates.
No, there is no limit — you are free to transfer your cash ISA as many times are you like. In fact, many savers use this strategy to chase higher bonus rates or better interest deals.
There are a couple of points to remember, though:
Completely safe. All these platforms are authorised and regulated by the Financial Conduct Authority (FCA) and in addition offer protection to the value of £120,000 by the Financial Services Compensation Scheme (FSCS).
There are two types of saving accounts – easy access, and fixed term. Fixed term means you will commit to leaving your money untouched in the savings account for a fixed period of time, usually in exchange for a better interest rate.
Conversely, easy access allows you to deposit and withdraw money whenever you like. What is interesting about this, is that at the time of writing this page, easy-access cash ISAs are offering the leading rates and there is therefore no advantage to locking your money away for a fixed term.
This depends on your age. If you are between the ages of 18 and 39, then a Lifetime ISA is a much better option as it attracts a government bonus of 25% on every deposit up to the value of £1,000 a year. You can either use this account to accumulate interest, or place your money into the stock market in order to grow a deposit.
For more information on Lifetime ISAs, and to find the best providers with the best returns at the lowest costs, go to my article here.
Yes, and you should! However, it is really important that you don’t just withdraw your funds and deposit them with a new provider as this will inadvertently affect your ISA allowance. Contact the provider you wish to transfer to and ask for their assistance in doing an ISA transfer.
A flexible cash ISA allows you to withdraw and deposit without affecting your ISA allowance. As an example, if I deposit £100 into a cash ISA that is NOT flexible, then withdraw £50, and deposit that amount back into the ISA, I would have used £150 of my ISA allowance. With a flexible ISA, this example would only use £100 of my ISA allowance.
Yes. The rules surrounding ISAs were changed to allow consumers to open multiple accounts with different providers as long as the total amount paid across all your ISAs within any one tax year still remains within the ISA annual allowance (£20,000).
Not necessarily - these are two very different vehicles for growing your wealth. Saving is better for anyone who might need access to their wealth within the next five years, whereas, investing offers the opportunity for better returns but is considered a long-term endeavour of at least 5 years.
