Broadband speeds in SW4
Share of SW4 premises by the fastest download speed available, averaged across all 895 postcodes in the district.
Full fibre and gigabit both sit at 90.3%, a solid figure but significantly lower than SW2's 92.5%. Superfast coverage reaches 99.7%, nearly universal. The gap between superfast and gigabit reflects a 7.7% segment in the 30-300 Mbps tier, indicating patchier fibre rollout compared to neighbouring codes. Networks capable of 300 Mbps extend to 91.9% of postcodes. Zero postcodes fall below Universal Service Obligation thresholds. This spread suggests a postcode where older and newer infrastructure coexist. SW4 includes more mixed-age housing stock than central Lambeth postcodes, explaining why fibre rollout has been less uniform. Despite that, gigabit reaches over nine in ten premises, and even the minority without gigabit have access to solid superfast speeds. For most residents, connectivity will support all common household uses.
