Broadband speeds in SW1P
Share of SW1P premises by the fastest download speed available, averaged across all 454 postcodes in the district.
Gigabit and full fibre both reach 90.6%, meaning nearly all premises connect to networks capable of delivering 300 Mbps. The small gap between superfast (93.9%) and gigabit (90.6%) reflects a legacy 30-300 Mbps segment; 3.3% of postcodes sit in this middle tier. This mix is typical of areas where fibre rollout has been recent but not uniformly complete. Zero premises fall below USO thresholds. Overall, 90.6% of postcodes support 300 Mbps or above. The broader Westminster postcode area's diversity means that as postcodes spread out from central offices towards residential streets, infrastructure ages slightly. SW1P captures both zones, explaining why it remains solidly above the UK average for gigabit but shows that small lag. Most households will experience no speed-related friction here.
