As far as my knowledge goes, there are no ‘NO CALL LISTS’ as such in the UK (except for probably their secret services department ;D).
However, there has been very strict action against Telemarketing organizations in the entire west last year. Crowds, rallies, demonstrations, etc. have been quite common and legislations have been passed against telemarketing calls (especially in reference to the B2C calls that call centers make).
I will see if I can get some information regarding any ‘NO CALL LISTS’ if there are any and I will be sure to let you know.
