Tembo Money Cash ISA reviews (3588)

Great customer service and product

It's been very simple signing up with Tembo, I've been able to save at a great rate and changes and accessing my details has always been transparent. In particular, I was pleased that extra security checks were in place when withdrawing larger amounts and I was quickly able to confirm the measures were authentic with the customer service team. Great app as well. Reviewed on: 4th February 2026

Came for the high rate, stayed because I love the app

Originally opened my ISA with Tembo because it was recommended on Money Saving Expert with a high interest rate. The app was so easy to use - adding money is easy as is tracking interest. Customer service were really helpful when I needed them. Reviewed on: 4th February 2026

The app is easy to use and I’m happy with the security.

The app is easy to use and I’m happy with the security. No problems, well done Reviewed on: 4th February 2026

Great experience from start to end

Whole experience from transferring an old isa to opening a new one was very good. The app is also a good way to keep track of your investments and managing the necessary transactions. Reviewed on: 4th February 2026

Some issues

Issues with some members of customer service talking down to me. Issues accessing funds due to adding biometrics without my consent. The rates are not market leading. The app is average. Reviewed on: 4th February 2026

Game Changer for my property and savings journey

I joined Tembo after a recommendation from a financial content creator on YouTube, and it has genuinely been one of the best financial decisions I’ve made. From the very start, the Cash ISA transfer process was completely seamless, and the app itself is incredibly intuitive and easy to use. But what truly sets Tembo apart for me is how empowering the experience feels. The constant education around mortgages—the why, the how, and the what next—has given me clarity and confidence, no matter where I am in my property acquisition journey. Tembo doesn’t just help you save money; it helps you feel informed, supported, and in control of your financial future. I absolutely love my TEMBO. Reviewed on: 4th February 2026
