Quick Summary

In south London's Herne Hill neighborhood, a bike shop called Bicycle Nation has been plagued by an unbearable stench since June, likely caused by untreated sewage stuck in Thames Water drains due to the lack of rain. The shop owner and staff have repeatedly complained to Thames Water, which recently acknowledged responsibility but hasn't provided a resolution date. The smell, described as "cabbage," "teargas," and similar terms, forces customers away and workers outside during frequent daily occurrences, affecting both health and business operations.

Story summary

A toxic stench from untreated sewage has plagued a bike shop in Herne Hill, south London, since June 2026. The smell, thought to come from Thames Water drains, has forced Bicycle Nation's owner, Tamas Polocz, and his staff of 11 mechanics to work outside at times due to its intensity. Despite repeated complaints, Thames Water acknowledged the problem but failed to provide a resolution date. The stench is so severe that it has caused a colleague named Nick to vomit, leaving Polocz and his team concerned about their health. This issue follows record-breaking temperatures and droughts that have highlighted the need for an overhaul of London's outdated sewage system.

Why this leaning score
This article does not take a side on a contested political question, so it has no leaning score. That is an answer rather than a gap: a match report or a rescue can be warmly or critically written without being left or right, and scoring it anyway is how approval of a subject gets recorded as a political position.
