Broadband speeds in ST21
Share of ST21 premises by the fastest download speed available, averaged across all 214 postcodes in the district.
ST21 presents the lowest connectivity metrics in the ST block. Of 214 postcodes, 79.1 per cent reach superfast, 40.5 per cent access gigabit, and 8.4 per cent (18 postcodes) sit below 10 Mbps. The speed split mirrors this disparity: 40.5 per cent at 300+ Mbps, 38.7 per cent in the 30 to 300 Mbps middle band, and 8.4 per cent below 10 Mbps. The 1.5 per cent Universal Service Obligation shortfall is low relative to the broader below-10 Mbps cohort, suggesting pockets of infrastructure but uneven deployment across the postcode area. That 38.7 per cent middle-tier population is the largest single band, indicating substantial postcodes trapped between gigabit infrastructure and undersupply. ST21 diverges sharply from ST4, ST5, and ST6 elsewhere in Newcastle.
