Broadband speeds in RH20
Share of RH20 premises by the fastest download speed available, averaged across all 867 postcodes in the district.
RH20 has a sharper two-tier divide than nearby Chichester postcodes, reflecting more dispersed settlement patterns. Gigabit networks cover just 51.7%, leaving 39.8% in the 30-300 Mbps band and 2% below 10 Mbps. That below-10 tail is more pronounced than in postcode areas closer to the coast or in denser suburban areas. Superfast coverage stands at 91.5%, meaning most households can reach 30 Mbps, but speed variation is significant across the outcode. For rural Chichester, this reflects the challenge of serving dispersed properties cost-effectively. The distribution shows clear infrastructure gaps in some areas.
