Broadband speeds in BN10
Share of BN10 premises by the fastest download speed available, averaged across all 526 postcodes in the district.
BN10 achieves near-universal superfast penetration at 99.1%, an outlier even among strong Sussex codes. Gigabit reaches exactly 82%. The speed distribution reflects this: 82% ultrafast, 17.1% on conventional superfast (30-99 Mbps), and nil below 10 Mbps. This is a rare case where no postcodes fall below superfast, and nearly one-fifth sit in the intermediate band. Wireless is absent. Below-USO premises account for zero. The tightness of this distribution suggests either older, purely-fibre infrastructure or a carefully planned network rollout. Most households here are positioned on reliable superfast service, with four-fifths reaching gigabit speeds. The technical quality of implementation appears consistent across the outcode.

BN10 broadband FAQs
What does 99.1% superfast mean for the average household?
Virtually every postcode meets superfast minimums (30+ Mbps). Only the 17.1% in the conventional band won't reach gigabit or ultrafast, but speeds of 30-99 Mbps are still solid.
Is gigabit widely available?
82% of postcodes qualify. High likelihood, though the 18% on conventional superfast will max out at 30-99 Mbps.
Why is there such a clear gap between the 82% gigabit and the 99.1% superfast?
Likely reflects network investment waves. Superfast infrastructure is universal; gigabit rollout has covered most but not all areas.
Are there any postcodes with slow speeds?
None fall below 10 Mbps, making BN10 connectivity universally reliable.
