Broadband Coverage in Llanelli
47,056 premises make up the Llanelli constituency in Wales. Full-fibre sits at 83.0%, above-average, and folding in gigabit-capable cable upgrades takes coverage to 83.0%. 97.5% of premises reach superfast (30 Mbit/s or more) and 83.0% reach ultrafast (300 Mbit/s or more).
On connectivity for all households, Llanelli posts one of the strongest USO records nationally, under 1% of premises remain below the 10 Mbit/s baseline. As gigabit networks become more common, Ofcom is likely to raise the ultrafast threshold in future Connected Nations reports.
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 Wales with comparable full-fibre coverage are listed below.
