Freeview customers are being warned they are set to lose 10 channels later today.
The changes come as one of the TV signals, COM7 Multiplex, is to be switched off later today in order to pave the way for 5G mobile technology.
While some are moving channels, others will be leaving Freeview for good.
Viewers are being urged to retune their TV’s and Freeview boxes in order to access the most up-to-date channels available to them.

Failure to carry out the update could lead to people losing some of their favourite channels.
While viewers are also being told to run a system update check.
A Freeview spokesman said: “Since the decision by Ofcom to make more airwaves available for mobile data, the Ofcom licence for some channels broadcasting on Freeview has expired.
"This means that affected channels are making changes to the way they are broadcast moving forward.
"Channels will be making changes to the way they are broadcast on 29th June 2022. You will need to retune your TV to continue watching these channels."
Among the channels to leave Freeview altogether include BBC News HD, PBS America+1, More4+1, QVC HD and QVC Beauty HD.
Forces TV, Quest HD, CBS Justice, Craft Extra and FreeSports are the other channels that will soon disappear.
