NatWest Cash ISA reviews (97)

Low interest rate

It was easy to set up an account with Natwest, however the interest rate was so low that I decided to move the bulk of my money to a different bank so that I could get a better return. Reviewed on: 9th August 2017

Terrible Interest

What's the point in tax free interest on savings if you have no interest to pay tax on? Reviewed on: 6th June 2017

Easy to understand and use

Makes saving digestible and easy. The app makes a big difference to this, allowing me to easily move money from my current accounts to my ISA Reviewed on: 4th April 2017

ok but nothing special

but that is frankly a larger issue Reviewed on: 4th April 2017

Fantastic Service!

I have been with Natwest for many years now, and I have never had a problem with them. However I recently opened a cash ISA and I realised just how good their products and customer service were. Their rates are really very fair and the support and advice provided by those who work there has been fantastic every step of the way. Highly recommend! Reviewed on: 4th April 2017

Unable to follow instructions

Attempting to set up account for my wife who has dementia with me acting as deputy power of attorney. So far this has taken over 4 weeks, they have all the relevant paper work but have decided not to follow my request to leave our joint account as is with both names showing and were in the process of removing her name. On complaining I was encourage to make a complaint this I have done and have been promised a call on Monday the 20.03.17. Having been a customer for fifty years I can only assume that loyalty counts for nothing. Reviewed on: 17th March 2017

Free money

I don't know what the rate is but the free 250 top up makes it so worthwhile. When we buy the house it means we'll have at least 2000 extra for nothing Reviewed on: 17th March 2017

gREAT ACCOUNT

Easy process, quick to set up, thoroughly recommend Reviewed on: 10th February 2017

Cash ISA

Easy to apply for one online and understand all of the information it provides on the account. Reviewed on: 10th February 2017

Go West!

I have been with Natwest since I was a child, thats well over 30 years ago. I collected all piggies when I was a child and have always been valued as a long time customer. The staff in the bank are friendly and in regards to my ISA-its been a great way to save money! Reviewed on: 5th February 2017
