Broadband speeds in SM3
Share of SM3 premises by the fastest download speed available, averaged across all 371 postcodes in the district.
Superfast reaches 99.7%, among the highest recorded in this batch. Gigabit capability is 88.3%, delivered by cable networks. Speed distribution is heavily weighted toward the high end: 88.9% of postcodes sit at 300+ Mbps and 10.8% at 30 to 300 Mbps. No postcodes fall below 10 Mbps. This tight, modern infrastructure reflects careful cable planning. The 99.7% superfast figure is striking; it means only three postcodes in 1,000 fall short of 30 Mbps. Cable provides all gigabit access; no full fibre is recorded. Outward codes rarely achieve this level of saturation and uniformity.
