On connectivity for all households, the 10 Mbit/s Universal Service Obligation minimum is met almost everywhere in South West Wiltshire, under 1% of premises fall short. The 300 Mbit/s ultrafast line is not fixed forever, Ofcom revisits its speed tiers as coverage grows.
Where these figures come from
Figures are drawn from Ofcom's Connected Nations 2025 report (July 2025, r01), which aggregates postcode-sector data to constituency level. They represent coverage availability from at least one network operator, not the proportion of households that have subscribed to a given speed tier, nor the typical or guaranteed speeds that customers actually receive. Nearby constituencies in England with comparable full-fibre coverage are listed below.
