Broadband speeds in OX3
Share of OX3 premises by the fastest download speed available, averaged across all 943 postcodes in the district.
Three-quarters of postcodes (75.3%) have gigabit, all delivered via cable networks. Cable maturity defines this area's infrastructure. Ultrafast is available to 78.4%, meaning speeds are spread across the high end of the available spectrum. The speed split is clear. 18.4% land in the 30-300 Mbps band representing older cable infrastructure, and 0.8% fall below 10 Mbps due to geography or distance from deployed networks. Full fibre has not been deployed here. Superfast reaches 96.8% of addresses, so fewer than 30 postcodes sit at 30 Mbps or below. Most households across Cherwell will have access to gigabit or solid ultrafast speeds suitable for demanding applications.
