Broadband speeds in SN9
Share of SN9 premises by the fastest download speed available, averaged across all 317 postcodes in the district.
Gigabit is rare here, available to only 22% of postcodes. Instead, two-thirds sit in the 30-300 Mbps band, the highest proportion of any code in this batch of 25 districts. Superfast reaches 86% of postcodes, below the UK average of 97%, but the infrastructure layer remains dominated by older fibre and cable that maxes out at standard speeds rather than gigabit. The 3.5% below 10 Mbps reflects the rural character, with scattered postcodes lacking modern infrastructure entirely. The below-USO rate of 0.9% is minimal. SN9's speed profile reflects distance and low population density. Cable and newer gigabit networks have not reached the smaller settlements and scattered addresses here. For most residents, the large mid-range band supports typical household use, though simultaneous HD streaming or intensive uploads can cause congestion.

Living in Wiltshire
Rural geography shapes these speeds. Most residents can stream and work online but will notice the difference from gigabit-served areas. The large middle band works for typical use but stalls with simultaneous HD streaming across multiple devices.
