Broadband speeds in SN12
Share of SN12 premises by the fastest download speed available, averaged across all 808 postcodes in the district.
Gigabit capability reaches 70.4%, typical for rural Wiltshire. Superfast is 94.2%, a good baseline. Speed distribution reveals 70.4% at 300+ Mbps, 23.8% in the 30 to 300 Mbps band, and 0.9% below 10 Mbps. This profile reflects a mix of cable-served suburban clusters and more remote rural postcodes reliant on alternatives to cable. The 23.8% mid-tier is significant, indicating substantial portions of SN12 lack gigabit despite meeting the superfast minimum. The 0.9% below-USO tail represents roughly seven postcodes and is lower than SN11, pointing to more consistent coverage across SN12. Cable provides the primary high-speed pathway; no full fibre is recorded. Verify individual postcodes but overall risk is low.
