Broadband speeds in TS21
Share of TS21 premises by the fastest download speed available, averaged across all 525 postcodes in the district.
TS21 is a connectivity challenge area across 525 postcodes. Superfast barely reaches 74%, gigabit only 40%. The speed distribution exposes the core issue: 40% at gigabit, 34% at 30-300 Mbps, but a substantial 13.3% below 10 Mbps, roughly 70 postcodes. Below-USO shortfall is 1.5%, some eight postcodes missing legal minimums. Wireless technology accounts for 10% of coverage, a modest supplementary layer. The pattern reflects County Durham here has incomplete superfast and gigabit rollout, where wireless helps but cannot close all coverage gaps. The 13.3% below-10Mbps share is well above typical for urban or semi-urban areas.
