On Wednesday afternoon a national re-tune event will see the News and Children's channels move to different channel numbers on the programme guide to allow extra capacity for new services. Please note that the BBC have also scheduled engineering work on transmitters in South Lakes, South Yorkshire and Gloucestershire on the same day which may require viewers in these areas to re-tune their YouView box to receive their BBC channels.
Most viewers will not have to do a re-tune of their YouView box for the channels to change, as this will happen automatically. If you want to retune manually you can press the YouView button on your remote control and go to 'Settings'> 'TV Signal & Quality'> 'Re-Tune Channels'.
You will also see some on-screen messages to tell you about the change, these are sent out by the Freeview broadcasting platform, not by BT. You can clear the message by pressing the YELLOW button on the remote control.
