CM2 broadband FAQs
Is gigabit the standard expectation in CM2?
At 89.2%, gigabit access is nearly universal; most premises can assume gigabit-capable broadband availability.
Are there postcodes with poor connectivity?
Zero fall below USO, and no postcodes sit below 10 Mbps, indicating connectivity failure is absent.
Why is ultrafast slightly higher than gigabit-specific?
Some premises have ultrafast fibre-to-the-cabinet connections rated at 30-300 Mbps, not gigabit.
What coverage does the large postcode count imply?
The 1,296 postcodes indicate a major urban or suburban zone; gigabit availability across this scale is a significant infrastructure achievement.
