How does the ISA Cashback Challenge work?

If you add money to a new or existing Zopa Cash ISA between 9 March 2026 and 5 April 2026, you could earn up to £50 cashback. 

Here’s what you need to do. 

1. Fund your Cash ISA during the offer period 

Pay into a new or existing Zopa Cash ISA (called a Smart ISA in the app) between 9 March 2026 and 5 April 2026: 

• Add £5,000 or more to earn £25 cashback

• Add £10,000 or more to earn £50 cashback 

2. Keep your money in your ISA 

You’ll need to keep at least the qualifying amount in your ISA until 1 July 2026. 

If you withdraw money during the offer period or before 1 July 2026 and your balance drops below the qualifying amount, you won’t receive the cashback. 

3. Get paid 

If you meet the criteria, we’ll pay your cashback into your Smart Saver account by 31 July 2026. 

Who can take part? 

To be eligible, you must: 

• Open a Zopa Cash ISA if you don't have one

• Open a Smart Saver account if you don't have one already

• Not have already signed up to another ISA-related challenge 

• Fund your ISA with new money, not money moved from another Zopa product 

• Not have already used your full 2025/2026 ISA allowance before taking part 

Your Cash ISA, Smart Saver and General Savings Account terms continue to apply. We may need to change these offer terms during the offer period. If we do, we’ll let you know in the Zopa app.
