Broadband speeds in TN8
Share of TN8 premises by the fastest download speed available, averaged across all 554 postcodes in the district.
Superfast coverage reaches 85.7% in TN8, solid baseline infrastructure across the district. Gigabit availability lags at 64.4%, indicating some premises without gigabit-class fibre infrastructure. The 21.3% in the superfast-only band reflects areas still dependent on 30-300 Mbps capability, adequate for household use but limited for simultaneous high-bandwidth tasks. Below-superfast premises comprise 6.3%, split between 1% at USO minimum and 5.3% above 10 Mbps but below 30 Mbps. This bottom tier suggests more dispersed rural patches than well-connected neighbouring regions, likely reflecting either lower investment priority or topographic challenges affecting infrastructure deployment. The split toward superfast-only is pronounced for a Southeastern outward code, hinting at either suburban sprawl without coordinated fibre rollout or infrastructure lagging behind more developed areas.
