The actual HGTV site program listings are showing no programs available from 14th January
https://hgtv.co.uk/tv-guide/undefined/?sd=2026-01-14
The listings on the broadcasters site only updated earlier today so there is till time for VM to update their EPG.
When the VM EPG differs from the website of the broadcaster's published schedule for programmes, you should email
tivoguideerrors@virginmedia.co.uk
Although they don't usually reply to the emails they will update the EPG with the correct info/metadata.
