Can I just second the comment from Vanilla about loan money issuing by fund transfer and solicitors not being notified. Many solicitors do not yet use online banking, and it can be days or even a couple of weeks before they get the written notification of the funds transfer. Also, when a loan cheque is issued, many lenders only charge interest when it is cashed, so you can order it ahead of time. With a funds transfer, you have to plan to a tighter timetable, and the potential for error\extra costs\ extra frustration is greatly increased.
Also, online banking, while avoid some problems, can create others - sometimes the time savings are more apparent than real.
