Tomorrow BBC Two will be the first analogue channel in London to be switched off.
Viewers with Freeview will need to retune their televisions in order to keep receiving it.
An estimated 12 million viewers will be affected in the London area, but the majority of homes have already switched to digital.
The biggest change to television in a generation is underway as the UK’s largest digital switchover begins across the London TV region.
From tomorrow, you will only be able to watch BBC2 if you have a digital television or an analogue TV with a digital set-top box.
