Broadband speeds in SS7
Share of SS7 premises by the fastest download speed available, averaged across all 1,094 postcodes in the district.
SS7's scale (1,094 postcodes) makes it a microcosm of Basildon's infrastructure unevenness. Gigabit passes 78.9%, but the postcode's main story is its mid-tier: 20.1% sit in the 30 to 300Mbps band, a substantial cohort for a single code. This suggests significant cable coverage without fibre, or older fibre generations. No postcodes fall below Superfast (99% have access), so the speed floor is 30Mbps. The distribution is tilted towards gigabit and cable, with surprisingly little tail. This composition reflects the postcode's heterogeneous infrastructure. Some areas have been built with fibre; others rely on cable only. Geography shapes speed access.
