    Brixton's Noisiest Streets — And How We Fix Them

    SW2 and SW9 residents face relentless noise from the A23 corridor, busy market streets, and one of South London's most vibrant nightlife scenes. Here's where we've delivered the biggest transformations:

    Brixton Road / A23

    The A23 is one of South London's busiest arterial routes, carrying 40,000+ vehicles daily through Brixton centre. HGVs, buses (routes 2, 3, 35, 45, 59, 109, 133, 159, 196, 250, 322, 333, 345, 415), and emergency vehicles from King's College Hospital push noise to 78–86dB during peak hours.

    Affected postcodes: SW2 1JG, SW9 8HN, SW9 7AA, SW2 1AG

    Coldharbour Lane

    A major east-west corridor connecting Brixton to Camberwell, carrying heavy bus traffic plus weekend nightlife noise from bars and restaurants. Combined traffic and entertainment noise reaches 72–80dB, particularly impacting Victorian terraces along its length.

    Affected postcodes: SW9 8LP, SW9 8PS, SW9 8LF, SW2 1TF

    Effra Road & Brixton Water Lane

    Connecting the A23 to Herne Hill, Effra Road carries significant through-traffic avoiding central Brixton. Combined with buses and the constant hum from the Brixton railway viaduct, noise reaches 70–78dB along the residential sections.

    Affected postcodes: SW2 1BZ, SW2 1DB, SW2 1EG

    Electric Avenue & Market Area

    Brixton Market's delivery vehicles from early morning, combined with weekend nightlife from Electric Brixton, Pop Brixton, and surrounding bars, create noise spikes from 5am–3am that affect nearby residential properties on Atlantic Road and Railton Road.

    Affected postcodes: SW9 8JX, SW9 8PR, SW2 1ET
