In accordance with the Communications Act 2003 and the BBC Charter and Agreement, the Broadcasting Code rules cover television, radio, and BBC on-demand programme services (such as the BBC iPlayer) only. Ofcom does not regulate radio stations that only broadcast on the internet, including most podcasts.
The exception to this is BBC podcasts. Those available via iPlayer Radio are subject to all the rules of the Broadcasting Code, as relevant. Ofcom can also advise whether podcasts on some other BBC online sites have met the required standards.
