Frequently Asked Questions
What speed is "superfast" broadband?
Ofcom defines Superfast as a download speed of 30 Mbps or above. Most ISP-marketed superfast plans deliver 35–80 Mbps in practice.
Is superfast broadband the same as full fibre?
No. Superfast typically means FTTC — fibre to the street cabinet, then copper to your home. Full fibre (FTTP) delivers fibre all the way to your property and is classified as Ultrafast or Gigabit.
Should I upgrade from superfast to full fibre?
Yes if it's available and the price difference is small. Full fibre (FTTP) gives dramatically faster speeds, better upload speeds (symmetric), and is more consistent than copper FTTC.
