Broadband speeds in SW1W

Share of SW1W premises by the fastest download speed available, averaged across all 321 postcodes in the district.

Gigabit and full fibre both reach 80.4%, well above the UK average of 69%. Superfast coverage reaches 94.3%, leaving a 13.6% segment with speeds in the 30-300 Mbps range. Over four in five postcodes support 300 Mbps speeds, which is sufficient for competitive home working and multi-device households. Zero postcodes fall below the Universal Service Obligation threshold. This profile suggests a postcode that has benefited from significant but incomplete fibre rollout. Kensington and Chelsea postcodes show more infrastructure diversity than Westminster's, reflecting their broader mix of residential, retail and cultural institutions. SW1W's slightly lower gigabit figure reflects this mixture. Despite that, connectivity remains strong, and the postcode's high house prices have attracted enough infrastructure investment to ensure excellent service across nearly all addresses.
