Jon, There is no specific requirement for power factor correction as far as I know. The Harmonics Emissions Standard BS EN 61000-3-2 1995 became mandatory 01/01/2001, this sets limits for the harmonic disturbance permitted on the mains - so it adds up to the same thing. .
It applies to all equipment having a mains input power consumption over 75 watts. Your type of equipment must meet limits defined as being Class A or Class D. Units fall within Class A unless they have a wave shape lying within a "special wave shape", in which case they are Class D. Class D limits are more onerous. Computers, monitors and televisions must meet Class D limits, irrespective of wave shape.. You need a copy of the standard for the limit tables and the "special wave shape".
