Amazing Cash ISA- Great Bank

I’ve been with NatWest since I was a kid, I had a Child’s account. I had a cash ISA for my savings, they always payed a competitive interest rate and my parents topped up. When I got older and was an adult I went into branch and it took just minutes to transfer my children’s cash isa over to an adult one and get another good interest rate! Amazing bank, I also use it for day to day spending. I would 100% recommend to everyone! Reviewed on: 17th April 2026

Savings Review Meeting

We wanted to make our Savings work more for us as my Husband has now Retired and i am looking at retiring in the next few years. We had to travel to our nearest Bank & make an appointment. We met a very nice lady very friendly. But we did come away after an hour thinking it was a waste of time, nothing against the lady Advisor, just it seemed that Nat West just wanted to push Credit cards, Mortgages, & loans. When we told her what we wanted and get a good Cash Isa with a good Interest rate for a large chunk of our Savings, she found one and then told us how to do it online at home as it could not be done in the Bank. At least she showed us how to do it as it was quite complicated online. Reviewed on: 16th April 2026

I've been with Natwest for years (opened my first ever current account and ISA with them) and whilst it's enabled easy access to my ISA and convenience for transfers etc, the value is not great compared to other rates on the market. Their online support chat function isn't great either Reviewed on: 27th March 2026
