Broadband speeds in SN11
Share of SN11 premises by the fastest download speed available, averaged across all 761 postcodes in the district.
Gigabit reaches 71.3%, higher than SN10 but still below the batch average. Superfast is 92.3%. Speed distribution across SN11 shows 72.2% at 300+ Mbps, 20.1% in the 30 to 300 Mbps band, and 3.7% below 10 Mbps. The 3.7% below-USO tail represents roughly 28 postcodes and is the highest in this batch, indicating serious coverage gaps. These premises likely rely on legacy copper infrastructure or sit too remote for modern cable rollout. The 20.1% in the mid-speed tier is substantial, representing mixed rural and suburban properties dependent on alternatives to cable networks. No full fibre is recorded in SN11. Uneven coverage means postcode checks are essential before committing to property.
