I have always found Triodos bank to be very good.

I have always found Triodos bank to be very good. I've had a cash ISA with them for quite a while and it's a huge relief to know that money is not invested into firearms or the fossil fuel industry. I've never had any issues negotiating their website, and over the years the layout, fonts and general ease of finding what you need to know has become much more user friendly.
