Broadband speeds in N3
Share of N3 premises by the fastest download speed available, averaged across all 589 postcodes in the district.
Gigabit reaches 75.9% of 589 postcodes here, backed by full fibre at an identical rate, confirming fibre-centric architecture with minimal cable. The 16.7% in the 30-300 Mbps band is notably high, suggesting either newer rollout stages or lower operator investment intensity. Superfast is near-universal (97.7%), so no postcodes fall below the USO minimum. Speed distribution across N3 is polarised: postcodes sit firmly in either gigabit or superfast bands. Single-operator domination means no cable gigabit alternatives exist. The postcode reflects mid-tier fibre deployment progress, neither central nor peripheral.
