Broadband speeds in SA38
Share of SA38 premises by the fastest download speed available, averaged across all 187 postcodes in the district.
Superfast (30 Mbps and above) is available to 82% of postcodes, a strong baseline. Beyond that, however, options shrink: gigabit capacity drops to 26.8%, concentrated enough that most households are likely to sit in the 30-300 Mbps middle tier. Indeed, 55.2% of postcodes fall there, suggesting a district where modern fibre is patchy rather than universal. The slowest end is limited: 7.7% below 10 Mbps, the smallest share in this cluster. Fixed wireless covers 26% of postcodes, indicating infrastructure diversity in more remote pockets.
