Ofcom imposes regional production quotas on each of the public service broadcasters, to ensure that a proportion of their network programming is made outside of London. In addition, the BBC and Channel 3 Licences have regional programming quotas which require them to make programming of interest to people living in the UK’s nations and regions.
See more on regional TV production and programming.
Under the Communications Act 2003, certain television broadcasters licensed by Ofcom are required to provide a proportion of their programming with access services (subtitling, signing and audio description).
