The Great British Spring Clean is an annual campaign organized by Keep Britain Tidy that encourages communities across the UK to come together and clean up their local areas. The initiative typically takes place in the spring and invites volunteers to pick up litter, tidy parks, and improve public spaces. The campaign aims to raise awareness about littering and its impact on the environment. It also promotes community spirit and encourages people to take pride in their surroundings. Participants can register their clean-up events online and receive support and resources from Keep Britain Tidy.
