You don't get it on the Freesat EPG, but you can get it in non-Freesat mode and, because it is transmitted FTA, you can also get it on any DVB-S Receiver.
For some reason, many UK punters are obsessed with "EPG" by which they mean a fixed Channel number, 7 day programme guide and, in the case of PVRs, easy high-level recording.
Euronews, like BBC, ITV and many others, pay for EPG slots on both BSkyB and Freesat.
Some Channels pay for BSkyB EPG, but not Freesat EPG.
Sky News is the most noteworthy of those: Perhaps because they see Freesat as a competitor to their own Platform!
A Freesat box, as you know, has a non-Freesat mode whereby you can scan in every FTA channel regardless of whether they pay for an EPG slot.
I think what Topper is referring to is that traditionally the Platform associated with a Channel (if any) is shown on listings sites.
But now there are two UK Platforms, it gets a bit convoluted.
eg Euronews is shown as a BSkyB Channel, despite also being a Freesat Channel.
Conversely, BBC, ITV etc are shown as Freesat Channels, despite also being part of the Sky Platform.
