This is a list of British television programmes. It does not include foreign-made imports. The BBC has stated, that in order for a series in the United Kingdom to be classed as a 'series,' then it must conform to the following requirements: The series must have at least 14 episodes per year, it must have been produced in the United Kingdom, and it must be aired on British television.

If a show contains less than this, it is considered to be a mini-series. Examples of such include Sherlock a British mini series following detective Sherlock Holmes, which was first piloted in 1990.

A television program (usually television programme outside North America), also called television show, is a segment of content intended for broadcast on television. It may be a one-time production or part of a periodically recurring series. A single program in a series is called an episode.

A television series that is intended to comprise a limited number of episodes is usually called a miniseries or serial. Series without a fixed length are usually divided into seasons or series, yearly or biannual installments of new episodes. While there is no defined length, US industry practice tends to favor longer seasons than those of some other countries.

A one-time broadcast may be called a "special", or particularly in the UK a "special episode". A television movie ("made-for-TV movie" or television film), is a film that is initially broadcast on television rather than released in cinemas or direct-to-video, although many successful TV movies are later released on DVD.

A program can be either recorded—as on video tape or other various electronic media forms—or considered live television.

Public television broadcasting started in the United Kingdom in 1936, and now has a collection of free and subscription services over a variety of distribution media, through which there are over 480 channels for consumers as well as on-demand content. There are six main channel owners who are responsible for most viewing. There are 27,000 hours of domestic content produced a year at a cost of £2.6 billion. Analogue terrestrial transmissions are currently being switched off and this is due to be completed in 2012.

Free and subscription providers are available, with differences in the number of channels, capabilities such as the programme guide (EPG), video on demand (VOD), high-definition (HD), interactive television via the red button, and coverage across the UK. Set-top boxes are generally used to receive these services; however Integrated Digital Televisions (IDTVs) can also be used to receive Freeview or Freesat. Top Up TV and BT Vision utilise hybrid boxes which receive Freeview as well as additional subscription services. Households viewing TV from the internet (YouTube, Joost, downloads etc.) are not tracked by Ofcom. The UK's five most watched channels, BBC One, BBC Two, ITV, Channel 4 and Channel 5, are available from all providers.
