@cfc, LCN changes are a permanent feature of the allotted numbers as channels come & go. most discussion appears to be on Digital Spy forums but the new Drama channel is being advertised on channels owned by UKTV. The programme line-up can be found on the LocateTV site.

What has happened to Sky sports on freeview.

Pete Green: Nothing, as these services were never on "Freeview".

"Freeview" is the brand name of the free-to-air digital terrestrial television (DTT) services.

There are some subscription services carried on DTT. These are by their nature not "free-to-air" and so don't come under the auspices of "Freeview".

The subscription slots formerly occupied by Sky Sports 1 and Sky Sports 2 were, I understand, paid for by BT. BT then allowed customers to subscribe to these services. BT has decided to replace the two Sky Sports services with its own BT Sport services.

Try channels 41 and 42. Now saying "Ceased Broadcasting. I know that they were not free. But were not from BT.

Pete Green: They were encrypted and BT subscribers had access to them, along with those of Top Up TV. So BT was definitely involved, whether directly or indirectly. It stands to reason that, ultimately BT (and Top Up TV) were providing finance for these services to be carried.

The BT Sport services are on DTT in lieu of the Sky Sports. BT has clearly put a lot into its BT Sport project, having secured the rights to high-profile sport and having hired high-profile presenters.

As the old saying goes "money talks", I should imagine.

Search the internet for information. Sky Sports is still available to BT customers, but streamed via their broadband connections (rather than over the air like a "normal" television channel). Customers whose connections aren't fast enough aren't happy.

The 2 Sky Sports channels are to be replaced with the 2 BT Sport channels in August. Much of the coverage will be football, rugby, tennis, MotoGP etc but many fans of other sports are less interested. BT do not have a price yet for these services after the first year free.
Those hoping to get the service via their broadband connect will, I'm told by BT, need a service of at least 5.6 Mbps, so many rural users will be disappointed. (I'm not despite a 2.1 Mbps ADSL line - I don't like football!).

have had to re-turn tv [and will do my freeview box] in order to get the latest channel number changes ie ch20. Why was no notification given of the need to re-tune or did I missed it?

You missed it! Easily done, it was in the small print in adverts for it. The adverts only appeared on UKTV channels such as Yesterday, Really, et al
