Broadband speeds in PO20
Share of PO20 premises by the fastest download speed available, averaged across all 1,246 postcodes in the district.
Gigabit reaches 65.2% of PO20's postcodes, marking a transition band between Arun's fibre-rich and fibre-sparse zones. The 65.7% reaching 300 Mbps-plus is substantial, but the 28.7% in the 30-300 Mbps band reflects real diversity. Below superfast, 0.2% sit below USO standards. Arun's PO20 thus presents mixed choices: gigabit is available but not default. Households should confirm options per address rather than assuming gigabit. The speed distribution suggests dual infrastructure: cable in denser areas, legacy copper mixed with wireless in thinner spots. Median residents can expect gigabit or strong 30-300 Mbps alternatives.
