The requirements relating to tariff charges and associated information are set out in the Communications Regulation Act 2002 and the European Communities (Electronic Communications Networks and Services) (Universal Services and Users' Rights) Regulations 2003, SI 308 of 2003, USO Regulations.
The Commission for Communications Regulation, ComReg, has responsibility for monitoring compliance by service providers with requirements under these regulations. In accordance with the regulations and following earlier public consultation, ComReg issued a direction to operators relating to a code of practice for tariff presentation on 12 August 2004. The core objective of the code is to ensure end-users have access to accurate, comprehensive and transparent tariff information in relation to publicly available telephone services.
