Broadband speeds in Cambridge
Share of premises by the fastest download speed available, averaged across every Cambridge postcode.
Start with the top end. More than nine in ten Cambridge postcodes, 92.5% to be exact, sit within reach of a gigabit-capable network, so connections built for 1,000 Mbps are the norm here rather than the exception. Superfast coverage at 30 Mbps or better runs higher still, at 98.5% of postcodes, a shade above the national norm of roughly 97 per cent. The slow tail has almost gone. Only 0.3% of postcodes record speeds below 10 Mbps, which across 2,637 postcodes amounts to a small handful of addresses rather than any recognisable pattern. For most households the practical question is not whether a fast line exists but which tier to pay for. A gigabit package is available to the overwhelming majority, and everyone else is very unlikely to be stuck below superfast.
