Broadband speeds in SS3
Share of SS3 premises by the fastest download speed available, averaged across all 591 postcodes in the district.
Gigabit reaches 91.9% of SS3, with ultrafast slightly broader at 92.1%. A noticeably larger mid-tier emerges here: 5.3% sit in the 30 to 300Mbps band. More concerning, 1.2% fall below 10Mbps, the highest below-10 share in the Rochford postcodes profiled here. This suggests pockets where neither fibre nor cable has reached. Superfast covers 97.3%, so most of SS3 meets the legal minimum, but the postcode is clearly less uniform than SS2. The speed stratification is visible. Some areas have gigabit; others lack even basic ultrafast speeds. Real-world data would clarify practical performance.
