The Big Switch Off – An evening to highlight the stars and raise awareness about saving electricity.
This year our Big Switch Off is taking place in the Lake Road area, Keswick Thursday 8th February and in Ambleside and Grasmere on Friday 9th February.
The Big Switch Off begins from 7pm onwards, and we’re encouraging as many residents and businesses in Keswick, Ambleside and Grasmere as we can to join in and turn off their lights overnight to see what a difference it makes to our view of the stars.
Please note that this has already taken place on 28/03/2024
