The key is staying within the £20,000 annual ISA allowance.
Using more than one Cash ISA
- Open and pay into more than one Cash ISA each year, as long as you stay within the £20,000 limit.
- Use different providers and spread your savings if it suits you.
- Split your allowance however you like - the total stays the same.
- Transfer ISAs without affecting your allowance if you follow the official process.
This can help you:
- Save for different goals.
- Mix easy access with fixed rates.
- Switch if you find a rate that better meets your needs.
