Broadband speeds in AB21
Share of AB21 premises by the fastest download speed available, averaged across all 801 postcodes in the district.
The gigabit story here is split. 72.5 per cent qualify for ultrafast or gigabit networks, but that advantage is offset by a substantial secondary market: 21.8 per cent of premises sit in the 30-300 Mbps band, a stretch into decent broadband territory but far short of gigabit. The tail below 10 Mbps affects 2.1 per cent (roughly seventeen premises), marking AB21 as a transitional district. Superfast coverage reaches 94.3 per cent, meaning 5.7 per cent fall short of even 24 Mbps. This dual profile fits a district mixing urban and semi-rural postcodes.
