Gigabit via cable covers 65% of postcodes across DN21's large 1,332-postcode footprint per Ofcom Broadband Availability Checker, below typical 2026 UK benchmarks at approximately 69% (Ofcom reported). Superfast (30-300 Mbps) serves 17.7%, with fixed wireless overlaying 50.9% to plug gaps where cabling is scarce or uneconomical. Below 10 Mbps: 8.1%, roughly 108 postcodes. Below-USO: 0.7%.

Gigabit is not universally available; many premises access superfast or fixed wireless services instead. Speed variance by address is substantial, reflecting infrastructure clustering.
