Broadband speeds in S41
Share of S41 premises by the fastest download speed available, averaged across all 992 postcodes in the district.
S41 achieves 98.8% superfast coverage across its 992 postcodes. The gigabit picture is also strong, with these speeds reaching most premises across the postcode district. The speed distribution shows: gigabit availability for the majority, 13.7% in the 30-300 Mbps superfast band, and no below-USO premises. The slight variation compared to S40 likely reflects newer fibre rollout phases and some premises still receiving legacy copper superfast infrastructure. The difference between the two Chesterfield postcode districts is marginal; nearly six in seven premises in S41 have access to gigabit. This aligns S41 with Chesterfield's broader connectivity story, reflecting significant FTTP investment across the town. Residents in gigabit-served areas can support multiple simultaneous high-bandwidth uses. Those on superfast still access adequate capacity for streaming and browsing without experiencing material constraints.
