Broadband speeds in SW1H
Share of SW1H premises by the fastest download speed available, averaged across all 81 postcodes in the district.
Gigabit and full fibre coverage both sit at 92.4%, indicating that nearly all premises have access to networks delivering 300 Mbps or faster. Zero premises fall below the USO threshold. No postcodes occupy the 30-300 Mbps middle ground; coverage is almost entirely gigabit-capable with a small tail of superfast. This split suggests substantial investment in high-capacity fibre networks across the postcode. The absence of a significant middle tier reflects deliberate infrastructure modernisation rather than patchy rollout. Premises here can expect either full fibre gigabit access or superfast backup, with no degraded middle options. The postcode's tight commercial cluster and resident density have supported concentrated investment in modern telecommunications.
