Broadband speeds in SM6
Share of SM6 premises by the fastest download speed available, averaged across all 737 postcodes in the district.
Gigabit coverage is 85.8%, serving most but not all postcodes. Superfast is 97.1%, strong but not exceptional. Speed distribution shows 85.8% at 300+ Mbps, 11.3% at 30-300, and 0.2% below USO. The speed ceiling is lower than in SM1 (88% gigabit), suggesting either patchy cable roll-out or more mixed premises types. The 0.2% below USO tail is negligible, but the 11.3% in the 30-300 Mbps band merits checking for work-from-home households with heavy bandwidth needs. Verify speeds before committing within SM6 given this variation.
