For paying the stamp duty and solicitors fees, about 4-5 years ago I had to go into a branch of Barclays to do it - although reading online now, it appears I can send anything up to £50K. How did everyone here do it (if you've bought recently)?
I bought about 18 months ago and transferred the different between the equity in our previous property and what was owed on the new one (stamp duty/deposit) online. It was about £65k - I bank with Santander.
