Broadband Coverage in Wales
Wales covers 22 local authority areas with a combined 1,569,380 premises, of which 76.2% can access a full-fibre (FTTP) connection and 79.1% have access to gigabit-capable broadband. The gap between full-fibre and gigabit figures reflects additional premises served by upgraded cable (DOCSIS 3.1) networks, principally in urban areas where Virgin Media O2's HFC infrastructure has been upgraded to support gigabit speeds without laying new fibre-to-the-premises.
Within Wales, coverage varies considerably at local authority level. Flintshire leads with 89.4% full-fibre coverage, while Ceredigion has the lowest proportion at 50.0% — a gap of 39.4 percentage points. No local authorities have more than 5% of premises below the Universal Service Obligation threshold, indicating a relatively even baseline of connectivity across the nation.
Superfast broadband (≥30 Mbit/s) reaches 96.3% of premises, while ultrafast (≥300 Mbit/s) is available to 79.5%. Full-fibre take-up — the proportion of premises that have subscribed to an FTTP service where one is available — stands at 37.1%, reflecting both consumer demand and the competitive broadband market. All figures are from Ofcom's Connected Nations 2025 report, published in July 2025 under the Open Government Licence v3.0.
