Broadband speeds in SG9
Share of SG9 premises by the fastest download speed available, averaged across all 510 postcodes in the district.
Gigabit coverage sits at 62.9%, the lowest in this cross-SG group. Ultrafast matches that figure, suggesting a district where cable networks and early fibre haven't yet fully saturated coverage. The speed mix reveals the challenge: 25.4% of postcodes receive 30 to 300 Mbps speeds, and 5.1% fall below 10 Mbps. That slow tail is four times the rate of SG6, marking SG9 as less uniformly connected. A 0.1% fixed-wireless presence indicates minimal recent intervention. Below-USO premises account for 0.9%, a modest share. Superfast broadband at 88.3% lags the UK average, signalling mixed infrastructure maturity. This district typifies areas where urban fibre deployment hasn't reached the suburban fringe.
