THOUSANDS of Glasgow Freeview users have been warned to carry out a TV retuning this month or face losing their favourite channels.

The service will move to new airwaves to allow for development to new mobile broadband services.

Transmitters will be updates across Glasgow between now and 2020, meaning users must retune their TV's on September 19 to keep their channels.

The required changes will take place at some local transmitters from 9am and Freeview channels in these areas will be subject to disruption during the day.

Work is expected be completed by late afternoon and anyone who finds they are missing channels after this can retune.

Satellite and cable TV will not be affected.

Around 20,000 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.

Some older aerials may need to be replaced to continue receiving all channels. Viewers may be eligible for free in-home support, including aerial work if needed.

Anyone who needs advice, or who finds they are still missing services after retuning, can visit the Freeview website at reeview.co.uk/tvchanges or contact the Freeview Advice Line free on 0808 100 0288.
