Freeview viewers in the Norwich area have been warned they may need to retune their TV this month to continue watching some programmes.

Some channels are moving to new airwaves to allow for the future development of new mobile broadband services. Channels affected include That's Norfolk, TruTV and Children's channel Tiny Pop.

Around 160,000 homes may be affected and Freeview will be running an information campaign to prepare people for the change on July 17.

Changes will begin at the Tacolneston transmitter shortly after midnight and affected services will be off-air overnight until 6am. After this, any viewers receiving their TV signal from here who find they are missing channels can retune.

Some TVs may retune automatically and some older aerials may need to be replaced to continue receiving all channels.

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