Natwest far outshine all other banks. I would not use another now. Reviewed on: 20th January 2018

Never been unfair

Never been unfair, always helpful. Advice gave us the correct product. Reviewed on: 12th January 2018

Dreadful interest rates

NatWest offers no incentive to save. I appreciate that base rates are not set by NatWest but the bank profits from the money stored by customers. They should be more fairly compensated, rather than hiding behind low interest rates as an excuse. Other banks are offering many tines more interest. The only positive is the iPhone app which is easy to use and gives plenty of information. Reviewed on: 3rd January 2018
