Broadband speeds in OX4
Share of OX4 premises by the fastest download speed available, averaged across all 1,317 postcodes in the district.
Gigabit speeds are available to 79.9% of Oxford's postcodes, meaning nearly four in five addresses have cable gigabit infrastructure. Full fibre is absent throughout the district. The 15.1% of postcodes in the 30-300 Mbps range reflect premises on older cable or those awaiting upgrade.

Most residents will have access to speeds suitable for home working and streaming.
