Broadband speeds in HP4
Share of HP4 premises by the fastest download speed available, averaged across all 725 postcodes in the district.
HP4 spans 725 postcodes with a notable gap between superfast and gigabit availability. 95.6% reach superfast speeds, yet only 53.8% access gigabit-class throughput. This imbalance reflects partial cable network reach. Cable delivers the gigabit services where deployed, but postcodes without cable access rely on copper networks capped at superfast levels. 53.8% sit at 300-Mbps-plus, whilst 41.8% occupy the 30-300 Mbps tier where typical household video and work demands remain manageable. 1.2% of postcodes do not meet Universal Service Obligation thresholds. The speed split is binary here rather than gradual. Prospective residents should verify their specific postcode's cable proximity, as access to gigabit cannot be assumed across the entire district.
