Broadband speeds in SY18
Share of SY18 premises by the fastest download speed available, averaged across all 220 postcodes in the district.
Superfast coverage is 73.6%, significantly below regional norms. Gigabit-capable networks serve just 64.6% of postcodes. The speed distribution is stark: only 64.6% of premises achieve 300 Mbps-plus, whilst 9% experience the 30-300 Mbps tier. Critically, 7.3% of postcodes fall below USO minimums, the highest proportion in this batch. The 220-postcode district presents genuine connectivity challenges for broadband-dependent households. Limited fibre deployment and reliance on older copper networks mean speeds are constrained across much of the area. Multiple factors conspire to limit speeds and coverage.
