By Chandraketu Tripathi · Updated April 2026 · Fact-checked Cash ISA · Updated April 2026The Trading 212 Cash ISA burst onto the UK savings market with a headline-grabbing 5.2% AER rate. While that rate has since fallen in line with the Bank of England base rate, it remains one of the best flexible easy-access Cash ISAs available in April 2026 — paying 4.58% AER for new customers including a 12-month promotional bonus. | Feature | Detail |
|---|
| New customer rate | 4.58% AER (incl. 0.98% 12-month bonus) | | Existing customer rate | 3.60% AER (base tracker) | | ISA type | Flexible Cash ISA | | Minimum deposit | £1 | | Annual ISA allowance | £20,000 (2025/26 tax year) | | Fees | None | | Withdrawals | Up to 3 business days | | FSCS protection | £120,000 | | Interest payment | Monthly (compounded daily |
What Rate Does Trading 212 Cash ISA Pay?As of April 2026, new Trading 212 customers earn 4.58% AER on their Cash ISA. This includes a promotional bonus of 0.98% AER fixed for 12 months on top of the underlying variable rate. The underlying rate tracks the Bank of England base rate minus approximately 0.15 percentage points — currently around 3.60% AER with the base rate at 3.75%. Existing customers and ISA transfers earn the underlying rate of 3.60% AER without the bonus. If you are transferring an existing ISA to Trading 212, you will not benefit from the promotional rate. 💡 The new tax year started on 6 April 2026, resetting your £20,000 ISA allowance. Opening or topping up your Trading 212 Cash ISA now locks in the promotional rate on new contributions for 12 months. Is Trading 212 Cash ISA Flexible?Yes — this is one of the most important features. A flexible ISA allows you to withdraw money and replace it within the same tax year without it counting twice towards your £20,000 annual allowance. For example, if you deposit £20,000, withdraw £5,000 and later replace that £5,000, you remain within your annual limit. Most fixed-rate Cash ISAs do not offer this flexibility. How Does It Compare?| Provider | Rate (AER) | Flexible | Access | FSCS |
|---|
| Trading 212 (new) | 4.58% | Yes | Easy access | £120,000 | | Chip | 4.84% | Yes | Easy access | £85,000 | | Plum | 4.51% | Yes | Easy access | £85,000 | | Marcus (Goldman Sachs) | 4.50% | No | Easy access | £85,000 | | Moneybox | 4.10% | Yes | Easy access | £85,000 |
⭐ OUR VERDICT The Trading 212 Cash ISA is one of the best flexible easy-access Cash ISAs in the UK for new customers. The 4.58% AER rate, zero fees, £1 minimum and £120,000 FSCS protection make it highly competitive. The main drawbacks are that the bonus rate only applies to new customers and current-year contributions, withdrawals take up to 3 business days, and there is no phone or branch support. If you are comfortable with an app-based service, it is hard to beat. Frequently Asked QuestionsCan I transfer my existing Cash ISA to Trading 212? Yes, you can transfer an existing ISA to Trading 212. However, ISA transfers do not qualify for the promotional bonus rate — you will earn the underlying rate of 3.60% AER on transferred funds. What happens after the 12-month bonus expires? After 12 months, your Cash ISA reverts to the underlying variable rate, currently 3.60% AER. You are free to withdraw and move your money to a better-paying account without any penalty or loss of ISA status if you transfer correctly. Is there a minimum deposit for the Trading 212 Cash ISA? No. You can open the Trading 212 Cash ISA and start earning interest with just £1. Can I have both a Trading 212 Cash ISA and a Stocks and Shares ISA? Yes. Since April 2024 you can contribute to multiple ISAs of the same type in one tax year, as long as your total stays within the £20,000 annual limit. Trading 212 offers both a Cash ISA and a Stocks and Shares ISA on the same platform. |
