Broadband speeds in LL36
Share of LL36 premises by the fastest download speed available, averaged across all 245 postcodes in the district.
Superfast availability of 83% masks significant connectivity disparities. Ultrafast deployment is weak at 19%, matching cable infrastructure without full-fibre support (0%). The speed tail is the real problem: 11.3% of postcodes report below-10 Mbps speeds, and a further 5.1% sit at or below the USO floor of 10 Mbps. Combined, 16.4% of premises face substandard broadband by current UK standards. The remainder splits into a superfast band (64.1% between 30-300 Mbps) and a small ultrafast contingent (19% at 300+ Mbps). For LL36, connectivity depends heavily on location within the postcode district; some premises enjoy cable gigabit, while others struggle with legacy copper constraints.
