Broadband speeds in CF10

Share of CF10 premises by the fastest download speed available, averaged across all 566 postcodes in the district.

This 566-postcode district relies heavily on wireless at 58%, a far higher figure than comparable Cambridge areas, indicating structural gaps in cable and fibre infrastructure. Gigabit reaches only 70.1% of postcodes, reflecting incomplete network deployment. The below-10Mbps tail is substantial at 6.9%, a material concern for urban premises. This reveals a district where wireless works as primary infrastructure rather than gap-filling supplement. Superfast coverage sits at 80.5%, notably below typical urban standards. The speed split shows 10.4% in the 30 to 300 Mbps band, a modest middle tier. Overall, CF10 shows connectivity challenges more acute than most southern English districts, suggesting broadband choice and quality should factor into move decisions. Wireless infrastructure plays a meaningful role alongside fixed networks, providing backup or primary connectivity to postcodes where wired deployment is impractical..
