SO21 postcode area guide — Basingstoke and Deane

Where is SO21?

Broadband & internet speeds in SO21

Mixed coverage

Broadband availability in the SO21 postcode district (Basingstoke and Deane) is Mixed — superfast is available to many but not all premises. Across the 732 postcodes Ofcom measures in SO21, superfast broadband (30 Mbit/s or faster) reaches 77.9% of premises and gigabit-capable lines are available to 25.7%.

Around 0.8% of premises in SO21 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.
