Broadband speeds in LL43
Share of LL43 premises by the fastest download speed available, averaged across all 28 postcodes in the district.
Gigabit reaches 70.8% of LL43, anchored by cable infrastructure (zero full-fibre). Yet 17.2% of postcodes fall below 10 Mbps, an outlier tail reflecting the rough topography or fragmented cable deployment across only 28 postcodes. The speed distribution is unusual: 70.8% access gigabit (300+ Mbps), zero sit in the 30-300 superfast band (speed_30_300_share is 0), and 17.2% slip below 10 Mbps. Below-USO premises are minimal at 1.8%. This odd binary pattern (gigabit or broken, with no middle ground) suggests LL43 comprises distinct clusters: one well-served by cable, another stranded on copper. Relocating here absolutely demands individual postcode verification to avoid the high-risk 17.2% zone.
