[F1Article 12 U.K.
Member States shall take steps to ensure that the tariffs for each of the services forming part of the universal service comply with the following principles:
prices shall be affordable and must be such that all users, independent of geographical location, and, in the light of specific national conditions, have access to the services provided. Member States may maintain or introduce the provision of a free postal service for the use of blind and partially-sighted persons,
prices shall be cost-oriented and give incentives for an efficient universal service provision. Whenever necessary for reasons relating to the public interest, Member States may decide that a uniform tariff shall be applied, throughout their national territory and/or cross-border, to services provided at single piece tariff and to other postal items,
the application of a uniform tariff shall not exclude the right of the universal service provider(s) to conclude individual agreements on prices with users,
tariffs shall be transparent and non-discriminatory,
whenever universal service providers apply special tariffs, for example for services for businesses, bulk mailers or consolidators of mail from different users, they shall apply the principles of transparency and non-discrimination with regard both to the tariffs and to the associated conditions. The tariffs, together with the associated conditions, shall apply equally both as between different third parties and as between third parties and universal service providers supplying equivalent services. Any such tariffs shall also be available to users, in particular individual users and small and medium-sized enterprises, who post under similar conditions.]
