On air and on social media platforms, it is encouraging listeners to make the switch to Freeview channel 730, where the station has had a presence since 1st April 2014.
Alternatively, the station continues to be available via mobile and online platforms.
In a statement, the RNIB confirmed the move was not a cost-cutting measure:
"We will provide the same high quality service we have always done. Also we found listeners were confused where to find us, this streamlining of how people can listen to us will make it much clearer how to find Insight Radio. RNIB will always strive to be efficient with budgets and costs to help provide the best service for our customers we can.
This change will also help put funds into frontline RNIB services to continue to help support people with Sight Loss and help make lives better every day.
With the switch to Digital TV a few years back, nearly all modern TV's now come with Freeview installed and no satellite dish is required either. It's also a free to air service meaning there's no monthly subscription costs using Freeview either. We believe this is the best platform to have Insight Radio to broadcast right across the UK into millions of homes. "
Broadcasting 24 hours a day, RNIB's Insight Radio communicates the needs, interests and aspirations of blind and partially sighted people throughout the UK. As well as covering news, sport, entertainment, talking books and social opportunities, in-depth feature interviews and lifestyle programmes address a wide range of issues affecting the blind and partially sighted community.
* Update: 09/02/2015 19:15 - despite the RNIB Insight Radio website stating "We're no longer broadcasting on Freesat", the service carried on Freesat channel 777 remains live as of 7pm. The station was removed from Sky earlier on Monday...
