Broadband speeds in S21
Share of S21 premises by the fastest download speed available, averaged across all 455 postcodes in the district.
Full fibre gigabit serves 79.9% of S21's 455 postcodes across Bolsover. Superfast covers 96.8%, leaving only 3.2% without reliable broadband and a bare 0.1% below the Universal Service Obligation. Most households here access gigabit speeds. Those on superfast-only services (16% of postcodes) benefit from 30-67 Mbps, acceptable for streaming and everyday connectivity. The 17-point gap between gigabit and superfast suggests rollout is still progressing through S21. This ongoing investment means postcodes without gigabit today may qualify within months or a year or two. Prospective residents should ask local providers about planned infrastructure upgrades when considering a move. The trajectory in S21 points toward eventual gigabit saturation across the district.
