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.
