Where these figures come from
Figures are drawn from Ofcom's Connected Nations Spring 2026 report (January 2026 snapshot, published May 2026 (r1)), 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.
