Broadband speeds in LL39
Share of LL39 premises by the fastest download speed available, averaged across all 18 postcodes in the district.
Gigabit coverage reaches 93.7% of postcodes, supported by cable (zero full-fibre). Superfast is available to 93.7%. Yet 5.4% fall below 10 Mbps, a puzzling discrepancy highlighting the granularity risk in tiny postcode districts of only 18 postcodes. The speed distribution splits cleanly between gigabit (93.7%) and below-10 (5.4%), with no middle tier. For such a small area, the 5.4% tail likely represents one or two premises stranded on legacy copper or facing routing constraints. The majority benefit from cable-backed gigabit performance.
