Earth Hour 2021 – Lights Switch off in Central London

Earth Hour is the world’s biggest switch off event and a time where millions of people unite for nature, people and the planet. It was started by WWF and partners as a symbolic lights – out event in 2007 in Sydney. In 2020, a record-breaking number of people took part in Earth Hour from over 190 different countries and territories, with over 9.5 million people taking part in the UK alone! It is one of the largest grassroots movements for the environment becoming a catalyst for positive environmental impact.

To show our support for this global event, we will switch off lights on the iconic building facades from 8:30 – 9:30pm on Saturday 27th March.

If you would like to show your support, the main event is to switch off non-essential lights in your home. WWF also have other ideas of what you can do at home including a digital detox or starry sky gazing – the guides are available on their website.
