BN45 broadband and area guide

BN45 is the smallest postcode group in this area and reflects rural Mid Sussex geography. Gigabit-capable networks reach 68.5%, placing it in the mid-range for this dataset. Speed distribution shows a clearer two-tier pattern: 68.5% achieve gigabit capability (300+ Mbps), while 23.3% occupy the superfast band (30 to 300 Mbps). Superfast availability is solid at 91.8%, indicating even non-gigabit premises enjoy adequate speeds. Only 0.4% fall below 10 Mbps, among the lowest risk proportions in this area.

The two-tier speed split suggests ongoing but incomplete fibre rollout, with cable or legacy copper serving the superfast segment and FTTP providing gigabit tiers. This deployment pattern is typical where initial investment has concentrated on higher-tier infrastructure, leaving earlier-generation networks serving secondary postcodes. BN45s small size and rural positioning mean individual postcodes may vary significantly from these averages. The gap between gigabit (68.5%) and superfast (91.8%) coverage shows infrastructure generational diversity. For households in the gigabit band, competition should support pricing. Those in conventional superfast tiers can expect reliable 30-99 Mbps performance.

Mid Sussex's smallest tracked postcode group enjoys moderate connectivity. Two-thirds can access gigabit networks. One-quarter rely on superfast 30-300 Mbps, which still handles streaming and remote work for most households.
