Since then the legislation has changed and I have twice quoted the title
of the legislation "THE CLEAN NEIGHBOURHOODS AND ENVIRONMENT ACT 2005,"
which actually reduced the requirement (from two keyholders to one and
only in areas designated by councils), but has been in force in both
England (since 2006) and Wales (since 2006/2007).

That allows councils to designate areas, it does not mean they exist.
