Broadband speeds in G21
Share of G21 premises by the fastest download speed available, averaged across all 612 postcodes in the district.
97.9% of G21's postcodes deliver real-world speeds exceeding 300 Mbps, a near-perfect alignment with gigabit infrastructure availability at 97.5%. Only 1.8% of addresses achieve speeds in the 30 to 300 Mbps range. Superfast coverage is near-universal at 99.7%, meaning fewer than two postcodes per hundred lack 30 Mbps service. This tight correlation between infrastructure and measured performance suggests G21's fibre network is both mature and actively provisioned. The small 1.8% segment operating below gigabit speeds likely represents postcodes in final provisioning stages or recent infrastructure deployment awaiting service activation. For residents, this means gigabit-class speeds are the expected norm.
