Broadband speeds in OL3
Share of OL3 premises by the fastest download speed available, averaged across all 577 postcodes in the district.
OL3 shows a two-tiered profile reflecting rollout in progress. Full fibre reaches 79.6% of postcodes with matching gigabit performance. Measured speeds confirm this pattern: 79.6% achieve 300+ Mbps. The remaining postcodes split differently. 11.6% sit in the 30-300 Mbps band, usable for most household activities but without the headroom for simultaneous heavy use. A small 8.8% lack superfast access entirely, marking postcodes where older copper infrastructure remains the primary option. Superfast coverage overall is 91.2%. This mixed profile is typical of districts where fibre deployment has been substantial but geographically uneven, reflecting economic and geographic factors that influence rollout pace. Postcodes with full fibre enjoy unlimited capacity; postcodes in the 30-300 Mbps tier require assessment of household needs.
