Broadband speeds in Sutton

Share of premises by the fastest download speed available, averaged across every Sutton postcode.

Gigabit-capable services reach 88.7% of premises in Sutton, an area of 14 outward codes taking in both SM and CR prefixes. That headline puts fast connections within reach of nearly nine addresses in ten. The superfast layer underneath is stronger still. At 97.8%, availability of 30 Mbps-plus speeds slightly exceeds the national average, and only 0.1% of premises fall below 10 Mbps. In practice these numbers describe an area where the network has largely been built out. Around one premises in nine still lacks a gigabit option, and for those addresses the ceiling is the superfast tier for now. Everyone else can choose between ordinary and very fast packages on price rather than availability. Across 3,734 postcodes, genuinely stranded addresses number very few indeed.
