The last analogue television channels will be switched off in Kent and parts of East Sussex today. The change will affect more than 450,000 households.
Analogue BBC One, ITV1, Channel 4 and Channel 5 will be turned off permanently at the Dover and Bluebell Hill transmitter groups.
People will then have to use digital receivers to watch television, for example Freeview or a cable or satellite set top box. For more advice on the Digital Switchover and how it could affect you click here.
