Broadband speeds in HP23
Share of HP23 premises by the fastest download speed available, averaged across all 555 postcodes in the district.
Superfast coverage in HP23 reaches 91.3% of postcodes, delivering consistent mid to high-speed broadband across this Buckinghamshire district. 71.2% of premises access gigabit capacity via cable networks, the primary infrastructure here. The remaining 20.1% occupy the 30-300 Mbps band, serviceable for household use but lacking the sustained throughput gigabit enables. Cable technology provides all high-speed services rather than fibre FTTP. Below that tier, 2.1% of postcodes fall short of the Universal Service Obligation threshold of 30 Mbps, affecting approximately 12 locations. For context, 71.2% reaching gigabit-class speeds places HP23 well ahead of rural UK averages. The absence of full fibre means copper or older technology serves the minority without cable.
