Inkeeping with the newish trend of mentioning companies that promote geographicals, I'd like to mention
The Riverside Group.
The Riverside Group clearly list geographicals for contacting them alongside their 0845 number(s).
I came across this company in the past (via google) and their website back then specifically mentioned that the geographicals was for their customers with inclusive price plans, etc. However they don't appear to mention this anymore.
I also note that they are still under the impression that the 0845 is 'local rate' which is a shame but at least they do list their geographical alternatives.
I may email them and point out that 0845 isn't local rate anymore and that most people ringing them would pay more ringing via the 0845 number than their geographical number.
