The multiplex - known as "COM7" will only be available to viewers with a Freeview HD certified device. Extra HD channels include BBC Four HD (channel 106), BBC News HD (107), CBeebies HD (74) and Al Jazeera English HD (108). Two standard definition channels - price-drop and Al Jazeera Arabic will become available on Freeview channels 37 and 84 respectively.
Viewers in much of Northern Kent, north Gloucestershire and Herefordshire who receive the full set of Freeview channels are likely to be receiving their services from the transmitter sites that are getting the extra multiplex on the 8th April 2014, although some viewers may be receiving from an alternative, neighbouring transmitter.

Viewers with Freeview HD devices will in most cases need to retune to get the extra channels. Alternatively, though manual tuning, viewers with Freeview HD devices can add the extra channels by entering a UHF channel number in the manual tuning menu. In both areas, COM7 broadcasts on UHF channel 32. Advice website www.tvretune.co.uk from Digital UK has more information on retuning Freeview equipment, but normal (non-Freeview HD) equipment will not be able to decode the new multiplex.
COM7 is being rolled out to cover around 70% of UK households by June 2014.
- At a number of transmitters, including Bluebell Hill and Ridge Hill, COM7 is being broadcast at a higher effective radiated power level than was previously announced in November 2013. Updated details for Freeview HD transmitters can be found here.
