Broadband speeds in LL37
Share of LL37 premises by the fastest download speed available, averaged across all 40 postcodes in the district.
Gigabit coverage of 97% is remarkable for a rural postcode district. Superfast is universal at 100%, and below-USO prevalence is zero. No full-fibre is recorded (0%), implying cable networks carry the gigabit capability. The speed distribution leaves no room for complaint: 97% of postcodes access 300+ Mbps, 3% sit in the 30-300 Mbps band, and zero fall below 10 Mbps. LL37's tiny size (40 postcodes) may mean the gigabit infrastructure is concentrated in one or two settlements, and outlying addresses might lag the averages. Nevertheless, the aggregate picture is uniformly excellent, suggesting systematic cable upgrade or pre-existing fibre or hybrid-fibre-coaxial deployment across the district.
