How channel numbers work

A channel number is a property of the platform, not of the channel. That single fact explains almost every confusion about them.

Each platform keeps its own list

Sky, Virgin Media, Freeview and Freesat each maintain a separate numbering plan. The same service can sit on four different numbers, and none of them is more correct than the others — which is why a single "what number is it on" answer is always wrong without naming the platform.

The low numbers are spoken for

Every UK platform reserves its lowest slots for the public service broadcasters, in an order set by regulation rather than by the platform. That is why the bottom of every list looks broadly similar while the middle looks nothing alike.

Blocks, not scatter

Above the reserved range, platforms group by genre: entertainment together, then film, then sport, then children. This is why a number's neighbours tell you as much as the number does, and why a genre index like this one is more durable than an alphabetical one.

Numbers move

Renumbering happens when a platform restructures a block, and it is rarely announced outside the platform's own guide. Any list of channel numbers is a snapshot, which is why every entry here is dated and why an undated list should be treated as unreliable.

Regions change the answer

Several services vary by nation and region, so the same number can carry different output in different places. Where that applies, the entry says so instead of pretending to a single answer.
