Broadband speeds in BT78
Share of BT78 premises by the fastest download speed available, averaged across all 1,142 postcodes in the district.
BT78 balances scale with mixed connectivity. At 1,142 postcodes, it is the second-largest code in the batch. Gigabit reaches 86.6 per cent; superfast covers 94.4 per cent. Alternative infrastructure appears in 20.9 per cent of cases, unusually prevalent for a large outward code, suggesting urban-rural mix across the district. The speed distribution shows 86.6 per cent at gigabit, 7.8 per cent at 30 to 300 Mbps, and 3.6 per cent sub-10 Mbps. Below-USO misses are minimal (0.8 per cent). The alternative infrastructure presence signals that whilst most of the 1,142 postcodes enjoy wired gigabit or superfast backbone, a significant cohort of dispersed premises (roughly 238 addresses) rely on wireless delivery. This is typical for an outward code spanning city wards and surrounding moorland.
