I use santander and have done since they took over alliance and leicester. It was free when i was with A and L and remains free today , lucky for me !!, though in regards to not wanting to mail cheques i pay them into the post office and they are sent to Santander at Bootle on internal mail , i've only had a couple of delays and no lost envelopes/cheques in 4 years or so with A and L and Santander and i pay in between 50 and 120 cheques per week.
