Broadband speeds in TN3
Share of TN3 premises by the fastest download speed available, averaged across all 562 postcodes in the district.
Sevenoaks TN3 differs from the Kent coastal codes in its connectivity model. All connectivity derives from conventional wired infrastructure rather than wireless alternatives. Superfast reaches 92% of these 562 postcodes, a strong baseline for household use. Gigabit, however, stops at 38%, concentrated in better-served areas. Speed distribution reflects this layered deployment: 38% hit the ultrafast tier, 54% occupy the 30-300 Mbps mid-range, and only 2.4% fall below 10 Mbps. This shapes a district where broadband is reliably adequate but not uniformly fast. The absence of below-USO postcodes confirms complete infrastructure coverage across the outward code.
