What’s New for 2026?
The Autumn Budget 2025 announced significant changes for Cash ISA savers. From April 2027, under-65s will only be able to contribute £12,000 per year to a Cash ISA (down from £20,000), with the remaining £8,000 of the ISA allowance reserved for Stocks & Shares ISAs. Over-65s retain the full £20,000 Cash ISA allowance. This makes 2026 an important year to maximise your Cash ISA contributions before the new limits take effect.
Additionally, FSCS protection has increased from £85,000 to £120,000 as of late 2024, giving savers greater peace of mind. Trading 212 continues to offer one of the most competitive flexible Cash ISA rates on the market for those looking to make the most of their tax-free savings before the rules change.

It’s best for digital-first savers who value managing finances on their phone. If you like quick setup, transparent rates, and seeing investments and cash ISAs side by side in one app, this is built for you — without queues or in-branch hassle.

Flexible ISA Means More Control
Being a flexible ISA, if you withdraw funds and redeposit them within the same tax year, it doesn’t impact your annual allowance. This gives you freedom to manage cash flow — take money out when needed and replace it later without losing your tax benefits.
Trading 212 Cash ISA Interest Rates: How Much Can You Earn?

Trading 212 Cash ISA vs Stocks & Shares ISA
Trading 212’s Cash ISA keeps your money secure and accessible, earning steady interest. By contrast, their Stocks & Shares ISA invests in markets, aiming for higher long-term returns but with more risk. Both are tax-free up to your £20,000 allowance.
| Feature | Cash ISA | Stocks & Shares ISA |
|---|---|---|
| Risk | Low | Medium to High |
| Returns | Interest only | Dividends & capital growth |
| Access | Immediate | Need to sell investments first |
| FSCS Protection | Yes | Yes |
| Best For | Emergency, short-term | Long-term investing |
Why many investors use both
Using both ISAs helps balance financial goals. The Cash ISA offers instant, low-risk savings for emergencies, while the Stocks & Shares ISA targets growth over years. This approach combines security with the potential for higher long-term returns.
Is the Trading 212 Cash ISA Safe?
Trading 212’s Cash ISA is secure, combining regulatory safeguards with strong platform security. Your money is protected up to £85,000, and advanced encryption plus two-factor authentication keep your account safe from fraud.
FSCS Protection
Your deposits are covered by the Financial Services Compensation Scheme (FSCS) up to £85,000. This means if Trading 212 or its partner banks fail, your money is still secure under UK regulations.
Trading 212 Platform Security
Trading 212 employs encryption, mandatory two-factor authentication (2FA), and holds funds with regulated banking partners. These layers of protection help safeguard your account against hacking and unauthorised access.
How Are My Taxes Affected by this ISA?
Interest earned in your Trading 212 Cash ISA is completely tax-free. You won’t pay income tax or report it to HMRC. Remember, your £20,000 annual ISA allowance is “use it or lose it” each tax year—so maximise it while you can.
What Do Real Users Think?
Real customers generally praise the Trading 212 Cash ISA for its easy setup, sleek app and hassle-free withdrawals that don’t eat into your ISA allowance. However, reviews note withdrawals aren’t instant (up to 3 days) and highlight the lack of branches or phone support.
Highlights from Reviews & Forums

- Complex Tax Calculation: Investors must account for reinvested dividends when calculating capital gains tax upon sale.

Final Verdict: Is the Trading 212 Cash ISA Worth It?
If you’re looking for a flexible, tax-free savings option managed entirely through your phone, the Trading 212 Cash ISA is a very strong choice. Its competitive interest rates (especially for new customers), lack of fees, and easy integration with other Trading 212 products make it stand out.
It’s perfect for tech-friendly savers who want hassle-free, on-the-go management of their money without branch visits. However, it’s not for you if you prefer fixed rates, face-to-face service, or a traditional high street bank feel. For many, it strikes a smart balance between convenience and earning tax-free interest.

FAQs
Is the Trading 212 Cash ISA flexible?
Yes. It’s officially classed as a flexible ISA, which means you can withdraw funds and redeposit them within the same tax year without impacting your £20,000 annual ISA allowance. This makes it ideal if you want to keep your cash accessible for emergencies or short-term needs.
Is my money protected by FSCS?
It is. Like other reputable UK banks and building societies, Trading 212’s Cash ISA comes with FSCS (Financial Services Compensation Scheme) protection. This means up to £120,000 of your savings is safeguarded per person, per institution, if Trading 212 or their banking partners were ever to fail.
Can I transfer an existing ISA in?
Yes. Trading 212 allows you to transfer existing ISAs from other providers directly into your new Cash ISA account. This is done within the app and helps keep your ISA savings all in one place. However, keep in mind that transferred funds typically won’t qualify for the new customer bonus interest rate.
What’s the difference between AER and APY?
In the UK, interest on savings is usually shown as AER — Annual Equivalent Rate. This figure factors in compounding and shows how much you’d earn over a year. APY is the US term for the same concept. Both help you compare savings accounts on equal footing by accounting for the effect of interest-on-interest.
Who should pick a Cash ISA vs Stocks & Shares?
A Cash ISA is best for short- to medium-term goals where you want security and easy access, like building an emergency fund. Your money earns interest without market risk. A Stocks & Shares ISA is geared for long-term growth, ideal if you’re comfortable with market ups and downs. Many people use both — keeping their savings safe in a Cash ISA while investing for future wealth in a Stocks & Shares ISA.
