A CONVENIENT CASH ISA

Spread your ISA allowance between multiple banks, all in one place. Then switch it between tax-free accounts in moments when higher rates arise.

SHIELD YOUR SAVINGS

Our Client Services team answer phone calls in 13 seconds on average. To give you the assurances you need, when you need them.

App downloaded correctly and instructions to set up very easy. It is self explanatory when surfing the app and there is sufficient information within the app to guide you accordingly ref: accounts and their set up. So far, all actions have been backed up by emails which I find helpful. The app isn't too 'busy' and very easy to use, giving clear insight as to where your money is and what it's up to!

Easy to use, good quality service. So far no problems. I personally don't like the no interest in the holding account, seems that a low rate of interest would be more appealing.

Seems very good, much easier than I read about, very quick, and some others I tried to register with were impossible!
