Hargreaves Lansdown’s Cash ISA is one of the UK’s most flexible tax-free savings accounts, giving savers access to exclusive rates from multiple banks through a single account. With a new market-leading easy access rate of 4.30% AER and a wide choice of fixed-term options, it’s designed to help you maximise your ISA allowance without the hassle of managing multiple banking relationships. Here’s our review of whether it’s the right Cash ISA for your savings.
Hargreaves Lansdown Cash ISA Expert Review: Updated 03/07/2026
Account: Hargreaves Lansdown Cash ISA
Description: The Hargreaves Lansdown Cash ISA is one of the most flexible Cash ISAs available in the UK. Rather than limiting savers to a single bank, it lets you spread your ISA allowance across more than 17 banking providers and 28 savings products through one account. You can mix and match easy access, notice and fixed-rate accounts, while managing everything under the same login as your investments.
Is Hargreaves Lansdown's Cash ISA any good?
Yes. Hargreaves Lansdown has one of the best Cash ISA platforms available if you want access to competitive rates without opening multiple bank accounts.
Unlike traditional Cash ISAs, HL’s Active Savings service gives you access to exclusive savings products from a range of banking partners. You can move money between providers and different fixed terms without leaving the platform, making it much easier to keep your savings earning competitive rates.
HL now offers an exclusive HL Easy Access Cash ISA (powered by Shawbrook) paying 4.30% AER, one of the highest easy access Cash ISA rates on the market that doesn’t rely on a temporary bonus rate. Because HL controls the rate rather than Shawbrook offering it directly, it can negotiate exclusive deals for customers.
The platform currently offers savings products from over 17 banking providers across 28 different accounts, including market-leading fixed-rate options. Current highlights include:
- Easy Access: 4.30% AER (HL Easy Access powered by Shawbrook)
- 1-Year Fixed: 4.41% AER (Atom Bank – exclusive to HL)
- 2-Year Fixed: 4.41% AER (Atom Bank – exclusive to HL)
- 5-Year Fixed: 4.40% AER (Chetwood Bank – exclusive to HL)
According to Hargreaves Lansdown, Cash ISA assets held on the platform have increased 88% year-on-year, reflecting growing demand from savers looking to lock in tax-free returns.
Mark Hicks, Commercial Director at Hargreaves Lansdown, says:
“With the proposed changes to Cash ISA allowances expected in April 2027, savers looking to maximise their allowance this tax year should act now to make the most of their tax-free savings.”
How does HL’s Cash ISA differ from a Hargreaves Lansdown Stocks & Shares ISA?
The key difference is that one is designed for saving while the other is designed for investing.
A Cash ISA pays interest on your savings, providing predictable, tax-free returns with no exposure to stock market volatility. Your capital isn’t at risk from market movements, making it suitable for short-term savings or anyone who prefers certainty.
A Stocks & Shares ISA invests your money into funds, shares, ETFs or investment trusts. While this offers the potential for significantly higher long-term returns, the value of your investments can rise and fall, meaning you could get back less than you invested.
One advantage of using Hargreaves Lansdown is that both products sit within the same account. This makes it easy to manage your savings and investments together and transfer money between your Cash ISA and Stocks & Shares ISA when your circumstances change.
Who is the HL Cash ISA best for?
The HL Cash ISA is particularly suitable for savers who:
- Want to earn competitive tax-free interest without opening several bank accounts.
- Like the flexibility of combining easy access and fixed-rate savings.
- Already use Hargreaves Lansdown for investing.
- Want access to exclusive savings rates unavailable directly from banks.
It may be less suitable if you’re simply chasing the absolute highest rate available, as an individual bank may occasionally offer a slightly better promotional deal. Likewise, investors with a long time horizon may achieve higher returns through investing, although those returns are never guaranteed.
Fun fact: If you invested the full ISA allowance every year for five years in a Cash ISA earning 4.30% interest, a basic-rate taxpayer could save around £1,400 in tax, a higher-rate taxpayer around £4,000, and an additional-rate taxpayer around £6,100, assuming current tax rules remain unchanged.

- Manage 28 savings products in one account

| Tembo Easy Access Cash ISA Review: Competitive Rate With a 12-Month Bonus CatchAccount: Tembo Cash ISA Description: Tembo’s Easy Access Cash ISA offers a competitive headline rate and a simple mobile-first savings experience. With 4.05% AER and unlimited withdrawals, it looks attractive for savers wanting flexibility and tax-free interest. But as with many high-rate ISAs, part of the return relies on a temporary bonus that investors should understand before opening. How Tembo’s Easy Access Cash ISA Works Tembo’s Easy Access Cash ISA allows savers to earn 4.05% AER (variable) on up to the 2026/27 ISA allowance of £20,000 per tax year, while keeping interest tax-free under the ISA wrapper. The account is designed to be simple and app-based, allowing customers to track their balance and interest growth through the Tembo mobile app. Interest accrues daily and is paid monthly, which helps savers benefit from compounding over time. The account also offers unlimited withdrawals without reducing the interest rate, making it suitable for people who want access to their savings without locking money away. Withdrawals can take up to 2 working days to process. One unusual feature is that Tembo links its savings accounts with its mortgage brokerage service. Customers who open a Tembo savings account are offered fee-free mortgage advice, which the company promotes as an added benefit for those saving for a house deposit. Savings held through Tembo are protected by the Financial Services Compensation Scheme (FSCS), although the protection level depends on the underlying partner bank where the funds are held. Tembo states that funds are protected up to £120,000, reflecting the structure of its savings arrangements. Is There a Catch? The headline 4.05% rate includes a temporary bonus. The underlying rate is 2.80% AER, with an additional bonus for the first 12 months. Once the bonus expires, the rate will fall unless Tembo increases the underlying rate. Overall, Tembo’s Cash ISA is competitive for new savers who want flexibility and a strong introductory rate, but the bonus structure and lack of transfers mean it’s worth reviewing the rate again after the first year. If you’re happy to lock away your savings for a year, it’s worth checking out Tembo’s 12-month Fixed Rate Cash ISA, which was offering a higher rate than its easy access ISA when we checked. Pros

| XTB Cash ISA Review: Competitive Rate Despite Bonus EndingAccount: XTB Cash ISA Description: Online trading platform XTB offers a 4% AER flexible Cash ISA, placing it among the most competitive easy-access ISA rates on the market. XTB's headline-grabbing 6% initial 90-day bonus ended in April 2026, but may return. Is XTB's Cash ISA Any Good? The 4% rate is not guaranteed. XTB’s ISA terms confirm that interest is calculated daily and credited monthly at a variable rate that may change. This means the base rate could rise or fall depending on market conditions. Is Your Money Held in a Bank or a Money Market Fund? Another key consideration is where client money is held. XTB states that Cash ISA funds may be placed in segregated client money bank accounts or in one or more Qualifying Money Market Funds (QMMFs). If funds are placed in a QMMF, they are not treated as bank deposits and do not benefit from traditional FSCS deposit protection in the same way as money held in a bank account. Instead, they fall under FCA client asset rules, with FSCS investment protection potentially applying in the event of firm insolvency, but not against investment losses. Is XTB’s Cash ISA worth it? XTB’s 4% is competitive but not the best rate we found. And funds may be held in a money market fund rather than a traditional bank account. If you are putting money away in the long run, the stock market can offer much better returns, so investing in a stocks and shares ISA may make you more money. Pros

| Moneyfarm Cash ISA Review: 3.87% AER Tax Free SavingsAccount: Moneyfarm Cash ISA Description: Moneyfarm’s Cash ISA offers a competitive introductory rate and flexible access to tax-free savings. With a boosted first-year return and daily interest, it aims to combine the simplicity of a savings account with the convenience of an investment platform. However, the headline rate comes with several conditions that savers should understand. How the Moneyfarm Cash ISA Works Moneyfarm’s Cash ISA allows savers to earn tax-free interest on cash savings, with a current introductory rate of 3.87% AER (variable) in the first year. After 12 months, the rate drops to 3.57% AER (variable). Interest is calculated daily, and you can deposit up to the £20,000 annual ISA allowance each tax year. Moneyfarm also allows free ISA transfers, so existing Cash ISA balances can be moved into the account without affecting your annual allowance. Unlike traditional bank savings accounts, Moneyfarm holds customer cash in Qualifying Money Market Funds (QMMFs). These funds invest in short-term, low-risk instruments and are designed to act like cash while generating interest. The rate paid on the account is linked to the yield of these funds, meaning it can change if market rates move. The account also offers some flexibility, allowing withdrawals when needed without penalties. What’s the Catch? The 3.85% headline rate only lasts for the first 12 months, after which the account reverts to 3.55%. To maintain the boosted rate, savers must keep at least £500 in the account and limit withdrawals to 3 per year. Exceeding this reduces the rate to the lower level. Finally, because savings are held in money market funds rather than a bank deposit, returns are variable and can change depending on market conditions. Pros

| Lightyear Cash ISA Review: Interest paid based on the Bank of England’s base rate Account: Lightyear Cash ISA Description: Lightyear’s Cash ISA currently pays 3.75% AER, designed to closely follow the Bank of England base rate. The account is fully flexible, has no account fees, no withdrawal penalties and no minimum deposit, and avoids short-term bonus rates that later drop. Savings are held across UK banks and qualifying money market funds, with FSCS protection applying to cash held in partner banks. How does the Lightyear Cash ISA compare with rivals? The Lightyear Cash ISA remains competitive thanks to its simple pricing, flexible terms and rate that tracks the Bank of England base rate, currently 3.75% AER (variable). You can withdraw and replace money without affecting your £20,000 ISA allowance, and there are no account fees, transfer charges or short-term bonus rates that later drop. While the rate is solid, it now sits more in the middle of the market in 2026, with some rivals like Tembo offering slightly higher easy-access ISA rates. However, many of those come with bonus periods, withdrawal limits or tiered rates that can fall after the first year. Lightyear’s appeal is its straightforward approach: one variable rate that follows the base rate and no penalties for withdrawals. Lightyear UK is authorised and regulated by the Financial Conduct Authority (FCA). FSCS protection applies to cash held with partner banks (typically up to £85,000 per person per bank), though this protection does not apply to money held in qualifying money market funds. Pros

Is the CMC Invest Cash ISA any good? Customers can easily transfer existing ISAs in-app, benefit from FCA regulation and protection of client money, and access the account within CMC’s wider investing platform, which serves over 1.5 million global users. The ISA is fee-free to hold (with an optional £15 urgent withdrawal fee) and sits alongside CMC Invest’s subscription plans that add investing features, lower FX fees and broader market access for those using the wider platform.

| Wealthify Cash ISA Pays 3.35% AER/3.30% Tax-freeAccount: Wealthify Cash ISA Description: Wealthify’s easy-access Cash ISA pays 3.35% AER (variable) with tax-free interest paid monthly, no fees and flexible withdrawals that don’t affect your ISA allowance. The account is powered by ClearBank, meaning deposits are FSCS-protected up to £120,000 per person per banking licence, and sits within Wealthify’s award-winning platform backed by Aviva. Is Wealthify's Cash ISA Any Good? Rates: Wealthify’s Cash ISA currently pays 3.35% AER (3.30% tax-free p.a., variable) with interest calculated daily and paid monthly. Because the rate is variable, the amount you earn can rise or fall over time, typically moving in line with changes in the wider interest-rate environment. One advantage of using Wealthify is that savers can easily move into investment products on the same platform if savings rates fall and they want the potential for higher long-term returns. As Wealthify’s Cash ISA interest rate is variable, the amount of money you get monthly will go up and down in line with any rises or falls in the Bank of England’s base rate. But, the good thing about saving with Wealthify is that if rates go down again, you can switch into investments. One of the things that came up when I interviewed the then Wealthify CEO Andy Russell, back in 2020 was that it’s hard to educate people to invest rather than save, so hopefully, this may be people’s first step into a wider world of investing. Market access & protection: Wealthify’s ISA is also flexible, so you can withdraw and replace money within the same tax year without affecting your £20,000 ISA allowance. However, as the FSCS’s compensation limit of £120,000 is per banking licence, and the Wealthify Cash ISA is powered by ClearBank, this means the £120,000 limit is shared across all accounts you hold with ClearBank. For example, if you have £100,000 saved in a Wealthify Cash ISA and £40,000 saved in another account powered by ClearBank elsewhere (including the Wealthify Instant Access Savings Account), only £120,000 of your deposits would be eligible for FSCS protection.’ App & platform: Wealthify’s website and app are simple and beginner-friendly, making it easy to open and manage a Cash ISA online. Customer service: Although there are no branches, customers can contact Wealthify’s UK-based support team by phone, email or live chat if they need help. Research & analysis: Wealthify provides guides, blogs and educational content about saving and investing, helping users learn more if they decide to move from cash savings into investments in the future.
