About air quality in Lambeth
Lambeth runs from the South Bank down through Brixton to Streatham, with the South Circular and Brixton Hill among its busiest air quality corridors. The borough’s roadside NO₂ remains a significant exposure for residents along these routes, though background levels have improved since the ULEZ extension in 2023.
PM₂.₅ levels track regional weather and transport rather than borough boundaries; large stretches of inner Lambeth share air with neighbouring Southwark and Wandsworth on most days. Several wards — particularly toward Tulse Hill and West Norwood — have no nearby monitoring site, so the borough-level verdict here is necessarily incomplete.
