Broadband speeds in SA48
Share of SA48 premises by the fastest download speed available, averaged across all 372 postcodes in the district.
Superfast is accessible to 74.8% of postcodes, a respectable baseline but well below national average standards. Gigabit capacity reaches only 43%, leaving most households reliant on mid-tier speeds. 31.8% of postcodes land in the 30 to 300 Mbps band, indicating substantial fibre and copper coexistence without universal modern infrastructure. The slow tail is material at 14%, one of the thicker slow-access concentrations in this batch and marking this 372-postcode Carmarthenshire area as having notable geographic barriers or infrastructure neglect in certain pockets. Below-Universal-Service-Obligation postcodes account for 4.3%, a small but real minority facing formal access guarantees and potential cost barriers. The gap between gigabit and superfast penetration shows uneven fibre rollout still in progress across the district.
