Stable account but low interest rate

The best banking app out there

I recently opened a Help to Buy ISA and a Savings Account with NatWest directly through their app. It's so easy to navigate and looks great too. Reviewed on: 24th January 2020

NatWest is helpful

The customers service at my local branch is high quality. The only negative about the branch is the working hours. Reviewed on: 2nd January 2020

Good experience with Natwest

I have had a ISA for many years. It was stopped when i went to live abroad. Now living in Britain, i wished to start it again. When i to the bank, expecting forms to be filled in and signatures given. I was very surprised to find that with a press of a few keys on the keyboard, i had been reinstated. Took about 5 minutes. Excellent. Reviewed on: 21st August 2019

Great user interface

The online banking app is what I have exclusively used, it is intuitive and pleasant to use. Reviewed on: 3rd February 2019
