Best Postcodes for Broadband in South East
Ordered by the share of premises that can order a gigabit-capable connection.
What this ranks on: the share of premises in each sector that can order a gigabit-capable connection. That is availability, not the speed delivered to any particular address. It is not a judgement about where is a good place to live, and AreaIQ Places does not score areas. Broadband and mobile checker (Ofcom) →
