HP12 broadband FAQs

How does HP12 recover from HP11?

Gigabit improves substantially across the area. More recent cable upgrades or denser development explain the improvement.

What about the 14.3% in the mid-tier?

These postcodes access 30 to 300 Mbps speeds, suitable for families but not ideal for simultaneous 4K streams or heavy uploads.

Are postcodes well-distributed across speeds?

Yes. 84% ultrafast, 14.3% mid-tier, and 1% slow creates a fairly clear segmentation.

Is HP12 good for working from home?

81.6% gigabit support remote work well. The remaining 18% at 30 to 300 Mbps should be fine for single-user home offices.
