Freeview viewers in the Shetland Islands may need to retune their TV equipment on 26 July 2017 to continue watching programmes. Some Freeview channels are moving to new airwaves to allow for the future development of new mobile broadband services.1 Following a decision by Ofcom, the media regulator, transmitters across the UK are being updated region by region as part of a major engineering programme being carried out between now and 2020. Engineering work at local transmitters will begin at 9am and Freeview channels including BBC One, BBC Two, STV, Channel 4 and Channel 5 will be subject to disruption until mid-afternoon.2 After this, any viewers who find they are missing channels should retune to get them back. Homes receiving their signal from the main Bressay transmitter or using satellite TV services are not affected. Around 2,000 homes are served by the affected transmitters. Freeview will be running an information campaign to prepare people for the change, including advertising and on-screen messages. Retuning should be straightforward and some TV equipment will retune automatically. Anyone who needs advice, or who finds they are still missing services after retuning, can visit the Freeview website at www.freeview.co.uk/tvchanges or contact the Freeview Advice Line free on 0808 100 0288. Some older aerials may need to be replaced to continue receiving all channels. Help will be available for viewers where this is the case.3 Further information is available online at www.freeview.co.uk/tvchanges – ends; notes follow – Freeview is working with Digital UK, broadcasters and Digital Mobile Spectrum Limited to provide information and support for viewers. In November 2014 Ofcom announced its decision to reallocate some airwaves used by Freeview to allow for the future launch new mobile services. Channels will be moving to new airwaves at the Baltasound, Scalloway, Swinister, Voe and Weisdale relay transmitters. For retune times, see www.freeview.co.uk/tvchanges. Services from the Collafirth relay will be temporarily off-air but viewers receiving their signal from here do not need to retune. Viewers in need of a replacement aerial to receive affected services following the change can seek help via the Freeview Advice Line. Equipment for other services that use Freeview channels, such as YouView, BT TV, TalkTalk, may also need to be retuned.
