Broadband speeds in LL48
Share of LL48 premises by the fastest download speed available, averaged across all 159 postcodes in the district.
Superfast covers 94.4% of LL48, a strong result for rural Gwynedd, yet gigabit is limited to 22.3%, reflecting minimal cable deployment. No full-fibre is recorded (0%). The speed pattern clusters in the superfast band: 72.1% of postcodes sit between 30-300 Mbps, while 22.3% access 300+ Mbps. Below-10 Mbps postcodes are rare at 2.3%, and below-USO premises are negligible at 1.1%. LL48 represents the typical rural outcome where copper networks or wireless backhaul deliver universal superfast access, but gigabit remains aspirational. For residents whose needs cap at HD streaming or small file transfers, LL48 is adequate; those requiring fast uploads or simultaneous heavy usage will find limits.
