Hi nath94,
It may depend on which package you are on.
Flash has been shown on Sky One and repeated on Sky Two. Both channels are available on most tiers and the shows are still free on catch up.
You can check which channels are available on your package here Channel Guide
You may find that according to that list you shouldn't have been receiving either Sky One or Sky Two.
Virgin have supplied over 50 channels for free, all for a limited period since the start of the current Covid epidemic. They actually extended the free periods for a number of the channels, however the free viewing periods have now ended.
At the time of this free promotion you could watch programs from those channels on Catch Up/On demand
Virgin supplied a range of Sky chanels for free during this period. Originally they were going to be free from April 10th to May 9th.
The full line up of extra Sky channels included:
Sky Arts
Sky Comedy
Sky Crime
Sky One
Sky Two
Sky Witness
Sky Sports Mix
Sky Sports News
Movies 2
Syfy
E!
If those channels aren't in your pack then you may wish to upgrade package, or take advantage of the Personal Picks option
Customers can add one Pick to their bundle for £7 per month with each subsequent Pick costing £5 per month. Picks can be changed every month.
The list of Personal Picks can be viewed here Personal Picks
Adding a Personal Pick and receiving extra channels for £7 a month is far cheaper than paying £2.49 per episode.
