Broadband speeds in SN5
Share of SN5 premises by the fastest download speed available, averaged across all 881 postcodes in the district.
Nearly all of SN5 meets superfast thresholds, matching the UK average precisely, and 94% can hit gigabit speeds. Speed profile is heavily tilted upwards: 94% of postcodes clock 300+ Mbps availability, and the middle and lower tiers together account for just 5% of addresses. Only 0.8% fall below 10 Mbps, suggesting very sparse gaps in the network. This level of consistency across so many postcodes indicates cable or fibre coverage that has been rolled out systematically, touching most addresses. The below-USO rate is negligible at 0.2%, meaning virtually everyone meets or exceeds the legal minimum. SN5 represents what modern infrastructure deployment looks like when executed completely across a large area, with the vast majority of households able to access the speeds needed for video conferencing, streaming, and online work simultaneously.

No. The gigabit availability comes via cable, not full-fibre FTTP. Cable networks deliver gigabit speeds competitively in this area.
What about the 0.2% below USO speeds?
Fewer than two postcodes sit below the Universal Service Obligation threshold. These few outliers warrant a direct ISP enquiry.
Is SN5 better than other Swindon codes?
Among the major codes, SN5 ranks highest for gigabit density and consistency. SN3 is comparable.
Can someone run a small business from home here?
Nearly always. 94% gigabit coverage and minimal speed failures make SN5 suitable for most remote work and videoconferencing demands.
