Freeview viewers in parts of Dorset may need to re-tune their television equipment to continue watching some programmes.

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 required changes will take place at the Rowridge transmitter group on May 2.

Changes will begin shortly after midnight and some Freeview channels will be off-air until 6am. After this, any viewers receiving their television signal from the main Rowridge transmitter who find they are missing channels can re-tune.

Services from some smaller local transmitters may be subject to disruption until late afternoon on May 2. Satellite and cable TV are not affected.

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