Broadband & internet speeds in SL2

Strong coverage

Broadband availability in the SL2 postcode district (Buckinghamshire) is Strong — superfast is near-universal and gigabit is rolling out. Across the 1,116 postcodes Ofcom measures in SL2, superfast broadband (30 Mbit/s or faster) reaches 94.3% of premises and gigabit-capable lines are available to 78.1%.

Around 0.1% of premises in SL2 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.
