About Unblocktober
Unblocktober is the world’s first month-long national campaign and awareness month to improve the health of our drains, sewers, watercourses and seas - driven completely by the British public.
Unblocktober takes place every October and challenges people to change their kitchen and bathroom habits at home and at work in order to help improve the health of our waterways.
Launched in 2019, the first Unblocktober saw more than 4,500 Britons across the country pledge to change their kitchen and bathroom habits at home and at work.
