Broadband speeds in PO18
Share of PO18 premises by the fastest download speed available, averaged across all 682 postcodes in the district.
Half of PO18's postcodes sit above the gigabit threshold (50%), whilst a significant cohort occupies the 30-300 Mbps middle ground. Superfast (30+) reaches 84.7%, but the remaining 15.3% tells a story of infrastructure gaps and investment priorities. The 4.6% below 10 Mbps are concentrated in outlying and rural areas. The speed distribution reveals a postcode in transition: strong cable presence in some pockets, patchy legacy copper elsewhere. Cable rollout has covered the denser zones; peripheral premises remain on older infrastructure or mid-tier alternatives. Over one-third of postcodes face switching constraints: gigabit is available nearby, but not guaranteed locally. Residents should verify coverage per address rather than assume postcode-wide gigabit availability.
