The online structure and ease of use works very well

The online structure with pc access and the app allow me to see how my finances are faring. I can very easily navigate around the sections to gather the information I require. Added to the ease of use the interest rates are very competitive. Reviewed on: 17th April 2026

Cash ISA enquiry

I had a query about my cash ISA, the online experience was limited and at a three day response time even after an acknowledgment was not really appropriate. The phone contact however was first class and resolved the issue as promised by (Tamara) ? Reviewed on: 17th April 2026
