THOUSANDS of Freeview viewers across parts of Dorset and Hampshire may need to retune their TV sets over the coming weeks.

Some Freeview channels are moving to new airwaves to allow for the future development of new mobile broadband services.

Following a decision by Government, transmitters across the UK are being updated region by region as part of a major engineering programme being carried out between now and 2020.

The changes will take place at the Rowridge transmitter group on 21 March and 2 May.

On both dates, changes will begin shortly after midnight and some Freeview channels will be off-air until 6am.

After this, any viewers receiving their TV signal from the main Rowridge transmitter who find they are missing channels can retune. Services from some smaller local transmitters may be disrupted until late afternoon on 2 May. Satellite and cable TV are not affected.

Around 920,000 homes are served by the affected transmitters but some TV equipment will retune automatically.

Anyone who needs advice, or who finds they are still missing services after retuning, can visit the Freeview or contact the Freeview Advice Line free on 0808 100 0288. Some older aerials may need to be replaced to continue receiving all channels.
