FREEVIEW viewers in parts of Sussex may need to retune their TV equipment to continue watching BBC programmes soon.

Channels are moving to new airwaves to allow for the future development of new mobile broadband services.

This comes as transmitters are being updated region by region as part of a major engineering programme being carried out between now and 2020.

The required changes will take place at the Dover transmitter group in the morning and are expected to be completed by 10am on August 22.

After this, any viewers receiving their TV signal from the main Dover transmitter who find they are missing BBC channels can retune.

Services from the Margate transmitter will be subject to disruption until late afternoon. Satellite and cable TV are not affected.
