Broadband speeds in LL35
Share of LL35 premises by the fastest download speed available, averaged across all 97 postcodes in the district.
Superfast coverage of 90.4% contrasts sharply with ultrafast availability of 7.7%, illustrating LL35's rural character. The ultrafast shortfall reflects an absence of full-fibre deployment (full_fibre_pct is null, indicating no recorded FTTP). Cable networks are absent, suggesting traditional copper or basic wireless backhaul supports the superfast tier. Speed distribution clusters in the mid-range: 82.7% of postcodes occupy the 30-300 Mbps band, while 7.7% reach 300 Mbps or higher. A concerning 4.4% fall below 10 Mbps, above the UK USO floor of 0.5%, reflecting patchy last-mile reach. Below-USO premises number 0.5%. Households in LL35 should expect reliable 30+ Mbps service; those seeking gigabit speeds will need to explore alternatives beyond the current postcode.
