Broadband speeds in RH17
Share of RH17 premises by the fastest download speed available, averaged across all 704 postcodes in the district.
Gigabit and ultrafast networks reach 48.3% of RH17's 704 postcodes, a figure that immediately signals patchier infrastructure than neighbouring Mole Valley or Lewes codes. The gap is filled by a substantial 43.6% of postcodes in the 30-300 Mbps band, a solid middle tier suitable for households but not ideal for data-heavy work. Above this, just over half the area lacks gigabit access. The tail is present but manageable: 2.4% of postcodes sit below 10 Mbps, primarily older or rural fringe locations, and 0.9% miss the baseline. Superfast coverage (91.9%) is nearly universal, but gigabit availability is very much the minority here. RH17 reflects a patchier rollout pattern.
