Santander Cash ISA reviews (81)

Worst investment I ever made.

Investment total has declined every single quarter since I made it. Have lost patience now, far better to leave under mattress!!!!! So angry with Santander!!!! Reviewed on: 22nd September 2022

Not empress

Couldn't open an account not impressed. I have tried a few time to open an account. So this is why I opened a Starling account. It was quick and easy to do. I would recommend it to my friends and family. Reviewed on: 24th January 2020

Not jappy

Not been too happy with this isa. I doubt it’s earning anything at all now. Reviewed on: 15th January 2018

Account is fine interest rate not the best

Not the best interest rate but no problems with the service Reviewed on: 22nd November 2017

Decent rates and easy to renew

The market rates for ISAs are not great at the moment, but I found that the rates offered by Santander were competitive, and allowed the inclusion of past ISAs. With online banking, it is easy to see the ISA options and rates available to you, and it is quick to select and finalise your choice without having to go to the branch. Reviewed on: 4th July 2017

good experiences at Santander

I had a problem with my mortgage during my divorce. i was on the point of having to sell my home to satisfy my ex wife. Santander helped me to remortgage and pay my ex wife a divorce settlement Reviewed on: 8th June 2017

Safe, but inaccessible

The security login process of both the app and online banking is so convoluted and difficult to remember the login details for, it totally puts you off login in. Which is not great of you want to keep on top of your money like me. Reviewed on: 7th May 2017

Disappointing

Longer to mature than other ISAs from other financial companies. Reviewed on: 17th April 2017

Santander is so helpful

Santander has been so helpful I've taken up a lot of their time asking questions and they are fabulous. Reviewed on: 12th February 2017

Better interest rate on savings

So far the best bank for savers in my opinion and they also offer a friendly and excellent service. Reviewed on: 14th October 2016
