Broadband availability in the CO2 postcode district (Colchester) is Excellent — gigabit-capable full fibre is widely available. Across the 938 postcodes Ofcom measures in CO2, superfast broadband (30 Mbit/s or faster) reaches 97.9% of premises and gigabit-capable lines are available to 81.6%.
Around 0.4% of premises in CO2 fall below the Universal Service Obligation (a minimum of 10 Mbit/s download and 1 Mbit/s upload), so the overwhelming majority of homes and businesses here can already order a decent fixed line. For a business that depends on its connection, the figures that matter most are gigabit and full-fibre availability — the symmetric, low-contention services we quote leased lines and FTTP against.
