It is expected that between 14 and 20 million households will need to retune their TV to access all the Freeview channels. The process of retuning is exactly the same as the first time you set up your TV. The tuning menu can be found in your TV’s settings and your set will search for all the channels automatically. If you use YouView, NOW TV, BT TV, TalkTalk and EE TV then you will also need to retune.
For some households retuning may not be enough. Ofcom predicts that between 100,000 and 160,000 households with indoor aerials will need a new aerial to continue getting all the channels they had before. The changes to the transmitters could cause issues for people with external aerials, too. Ofcom expects 40,000 to 100,000 of these aerials will need to be realigned. This procedure will usually need to be performed by a professional. In some rare cases viewers may even need to change their TV platform entirely. Satellite TV and cable TV services, such as Virgin are unaffected by the changes to the transmitters.
The 700 Mhz spectrum, which is used to wirelessly transmit digital TV signals, will be auctioned off in 2020 to provide a boost
for 4G and 5G mobile signals. In the lead up to the auction, alterations are being made to the TV transmitters to make the transition as smooth as possible after the auction. The majority of the transmitters in the south of England, some in the midlands and northern Scotland have already been altered. The transmitters in most of Wales and the remainder of Scotland will be changed towards the end of the year. The south west and north east will follow in 2019.
Everyone using Freeview will need to retune, but for people living in certain areas there’s a higher chance that you’ll need a new aerial or risk losing channels. Digital TV is broadcast in different aerial groups to different parts of the UK. Aerial group C/D uses the 700 MHz spectrum and people in this areas with these transmitters are at a greater risk of losing channels, though Digital UK’s website does say that households in this band should still continue to receive reliable reception. You can see on the map to the right which areas of the UK have C/D transmitters.
