Broadband speeds in L37
Share of L37 premises by the fastest download speed available, averaged across all 676 postcodes in the district.
L37 represents a strong connectivity story within Sefton. Gigabit reaches 90.4% of the 676 postcodes, and superfast covers 97.6%. The remaining 7.2% sit on 30 to 300 Mbps speeds, and 0.1% fail the USO minimum (likely one postcode in immediate need of intervention). This profile suggests L37 encompasses both fully deployed modern areas and pockets where fibre rollout is ongoing or where older infrastructure persists. Across 676 postcodes, the distribution shows reasonable concentration at gigabit levels with a small tail in slower tiers. The 7.2% intermediate population is manageable but material to connectivity expectations. Speed variation within L37 is moderate, indicating a district in transition or with mixed-age housing stock.
