How do I get the boosted rate?

To earn a boosted interest rate of 3.75% AER* (variable), simply:

1. Open an Access ISA pot – boosted rate in the Zopa app between 6 April and 5 May 2026.

2. Add up to £20,000 – money moved from existing Zopa ISA won't qualify.

3. We'll automatically apply the 0.5% AER* fixed bonus rate for the rest of the tax year – bringing your total rate on this pot to 3.75% AER* (variable).

Will I only earn the bonus rate on the money I added before 5 May 2026?

Is there a minimum amount that I need to add?

What will happen when the bonus rate ends?

*AER stands for 'annual equivalent rate'. We pay you interest on a monthly basis, but AER shows you the rate you’d get if this monthly interest was compounded and paid once a year instead. We provide an AER to make it easier for you to compare our rates with other providers.
