On connectivity for all households, the 10 Mbit/s Universal Service Obligation minimum is met almost everywhere in Belfast South and Mid Down, under 1% of premises fall short.

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.
