Broadband speeds in LL71
Share of LL71 premises by the fastest download speed available, averaged across all 85 postcodes in the district.
Gigabit capacity affects just 35.3% of postcodes, leaving 40.8% in the superfast 30-300 band. The below-superfast tail hits 15.7%, the joint-highest in this batch, indicating widespread infrastructure lag. Below-USO reaches 5.9%, the fourth-highest in the range. Wireless services are barely present at 1.9%, offering minimal alternative routing. This is a struggling zone compared to high-performing Anglesey neighbourhoods. Legacy copper and incomplete fibre or cable rollouts have left a significant population on slow connections. Most premises here sit on copper or basic cable delivering mid-tier speeds at best. Dependable gigabit access is limited to one-third. Households with heavy broadband demands may find performance inadequate. The infrastructure profile reflects delayed rollout completion. One in six premises cannot access superfast throughput reliably. Speed outcomes are unpredictable across postcodes.
